Hey Scotty, can you check the mileage on a used car with Bluedriver?
Scotty, must you take the Lord’s name in Vain?
Hey scotty didn't you live in Texas? I always thought you live there cuz the car plate showed texas now shows Rhode island
Scottykilmer why do you always work on Toyota? You are a Yank, work on Mustang, Camaro, Challenger or Charger.
Changing the differential fluid is something that's often overlooked. The best rule of thumb is when you change the transmission fluid or gear oil change the differential fluid too. But if you have a truck and you are loading it down it's a good idea to change the fluid more often.
And it’s not lifetime. Do it at 60 K.
And dispose of it in a non-jerk way. Burning it in an old pan outside is fine if you live in the country.
scotty is a legend. his expertise on cars is amazing!!
I'd like to hope so seeing he's been a mechanic for 54 years.
Just did this in our 2012 Rav4, so easy. I was $65 all in (had to buy a different allen wrench that could fit into the front fill plug, used Mobil1 75w-90, and a really simple pump from Advanced Auto) and it took about 1 hour. Local shop wanted to charge $296.
96$!! For the job,,, 200$ for there out Sunday trip
Under 25 for me 13 for 1Q gear oil, $6 10 mm hex socket, $5 Walmart marine pump
@@jonmo2694 nice, yea the more I think about it, I'm thinking it was more like $45. 1qt oil, new hex wrench (long handle), new cheap pump
Scotty keeps us on our toes with vehicle maintenance!
He sure does
Be sure to use the right fluids. Some manufacturers use special fluid, especially in the transfer cases. Like certain Hondas. In our fleet, we have an 07 Ridgeline that takes a specific fluid for the transfer case, since it is AWD. Major damage can be done if the wrong fluid is used, so always follow the recommendations in your owner's manual. And I highly recommend buying the exact fluid from the dealer. Yeah, it's more expensive, but not as expensive as replacing a failed unit because the wrong fluid was used!
My 09 Honda has a crappy front end and a little rust, but it is paid for! Made in Canada, shifts like a dream and well taken care of!!! Been driving it everywhere, almost from day ONE of finding Scotty's channel....back when he had only a couple of million subscribers. Scotty is THE MAN!
My husband and I are going to buy the last vehicle we'll ever own since we are in our upper sixties. we want a small suv . We thought about rav4 but you said new are not the best.I really appreciate your help
I'm 70 years old and for the first time in my life, the Tacoma truck I bought in 2012 is worth more than I paid for it brand new. Has 72,000 miles on it and I had to replace my 80,000 mile Dunlops because of dry rot not because the tread was worn out. I know it doesn't need a tune-up yet, but 13 years old is 13 years old.
Water pump, differentials, transfer case (if applicable), and transmission fluid change if you’re going to keep it 😀
Wow, you got your money's worth on those tires
@@joshr8666 I get my money's worth on my cars too.
Mine go bald every 6 months 😂
@@isaacainley5876 Do you drive a lot of miles on cheap tires? Or do you have the low pro thin tires?
My Michelin tire guy told me they wear down fast and are expensive. I would have bought a Toyota Venza, but it had low pros, so I passed. Looked easy to bend a rim.
New vehicle manuals suggest mileage intervals to change oil and or coolant and or transmission fluid are to long between changes that I usually halve the mileage recommended.
Bought a 2017 Toyota Camry XLE in 2021 and I completely went through all the fluids and changed them all.
Even the brake fluid which was fairly clean but I wanted to bring my car up to date with me as a new owner.....starting fresh.
The Michelins that came on the car were OEM and the fronts were pretty much done when I got the car with 27k miles.... inspectable but.......drove with them through the summer and fall.
So that tells me the previous owner never rotated the tires......so I bought a new set of 4 tires plus an alignment just before the winter months.
My car drives like a dream......smooth as butter.
Did this today to my Rav 4! Thanks Scotty!
What would we do without you Scotty?!? No one else is helping us and giving us information on stealerships and our vehicles like this, these days!
It is true!!!!
God, please bless Scotty and his family and all his grandchildren for all Scotty's kindness to people around the big World.
You are 100% right Scotty maintenance is everything. And Toyotas need maintenance they will last much longer if you do the proper maintenance.
The electronics are the first things that will show age
@@DavidNgo86 Unfortunately you are so right.
Hello Scotty,
Great stuff! I particularly love the fact that you advise your huge audience to crack the Fill Plug first and then the Drain Plug! I have witness so many mechanics make the mistake of draining a gear box before they ensure that they can fill it! LOL 😁😄😃😀😆😅😂🤣
Chuck Whigham
really was great advice!
Cracking open the fill plug also allows the fluid to drain better. Allows some air in as the fluid drains out. But yes check to see if you can loosen it first. That would suck if you cant get the plug out. Also make sure you use the correct sized hex as well. Don't strip it. Also if its tight tight bump it loose with a rubber mallet, not a steel mallet.
Can you explain why to use a rubber mallet versus a steel one ?
I do not recommend using a 5 gallon hard plastic water jug to hold your oil. Have you ever seen those things crack? They're not very forgiving. Laundry detergent containers are the best. You could throw that thing out of your truck while you're driving and it would be fine. But the plastic water jug is asking for trouble. 😮 🤦🏻♂️ 🌊 🤸🏻
Good that he mentioned about the tires. Of course, most people won't believe it. That's ok, because I make a lot more money off of replacing AWD units than I do from tires...
Scotty is the best mechanic teacher on the earth and youtube!!
When I do my diffs/transfer case on my 4Runner I use two sets of ramps, has always worked really well, just another option.
I'm a native of the Az desert and have had 4x4's most of my life. I had mentioned this to a friend who bought his 1st and he didn't listen and couldn't get it loose after draining it. I also mentioned that he should at least run the 4x4 units once a month for about 10 or so miles to keep the seal's from drying out because it could cost good money if they start leaking and it doesn't take long with our climate to dry out the seal's.
i also have a 4x4 but almost never use 4WD, would not changing the rear differential oil still cause damage to the gears?
You are always using the rear axle. You can get away with not changing the front if you aren't using 4x4, but the rear should be done at least.
In some vehicles, like mine, the front differential is always turning but not under load. I'd recommend to just change them both at the same time, along with the tranfer case fluid (In mine it's transmission fluid), in most cases it is. Use whatever spec & fluid type is recommended by the manufacturer
@@JamesFlynn-np7sq really appreciate the answers but sorry for my lack of knowledge as I never understood the difference between transfer case oil and the rear differential oil? (and yes i only use what the manual specifies always)
Here’s a tip. Don’t forget to use Teflon tape on the drain and fill plug threads. It makes it a whole lot easier to get those plugs off again. I never had any of them back out even with anti-seize compound on those threads. They were even worse to get out with the old differentials that used a 3/8 square that fit a 3/8 drive ratchet.
Scotty thank you so much for your sharing of automotive information. You have saved me a lot of money. Wish there were more truthful mechanics like you. God bless you and your family.
So running overly worn front tires with less worn rear tires hasn’t already screwed up the AWD system?
Great advice as always. Scotty, you should stay longer, leave in August, it seams you just got to RI. 😊
I did that on my 2018 Ford escape Awd the ptu, the transmission and what a pain in the butt to change the diff fluid but I've done it!! Thanks Scotty
Same, I have a 2013. Ford really stuck it to us with that rear diff. I was only able to get about 1 pint out but it took a full quart to fill. Also nice job Ford for having the factory fill extremely low.
I understand the replacing of all 4 tires so they are the same size, but why is ok for the AWD system to drive on unevenly worn tires?
I'd think having the front to rear so different wear wise would also damage the system the same way replacing only the front would.
Watched a TH-cam about 5 things good mechanics do. Loosen the fill before you drain was on the list. There’s Scotty showing off how good he is
I had a VW that had a 19mm Allen screw in it, Had to go buy one, guy at the auto parts store knew what year my VW was, 1972 Super Beetle.
Highlighting the order of removing the plugs is great advice.
Nice. I like to flush a few ounces through with drain plug out to rinse the old. Especially if the fluid was really bad. 😊
this would be my next level of challenge. I can do my engine oil and filter quite well now. Mine is a 2006 Highlander. Wonder what type of washer I should get.
Scotty's the man!!!! Always helping us u tuber fellars n fellets out with maintenance!!! You rock 🪨 Mr. Scotty!!!
I just changed my transmission, transfer case and rear differential fluids in my 2019 Honda Ridgeline. It was easy and saved a lot of money.
I assuming this is the same process for a Mazda CX5 which is all-wheel drive more or less. Love your videos BTW Scotty -- very informative!
it is no joke, i have a ford explorer (mazda tribute) 3L 2009 and nobody ever changed the gear oil. it was noisy AF before i fixed it.
My neighbor did this for me last weekend. It was black toxic sludge. I've heard people say it's good for life, but no it's not.
I had a hard shifting problem in my auto trans, changed fluid and filter, smooth as silk now
Drags fill tube through sand on driveway. Introduces sand into differential.Yikes!
So your saying with an awd vehicle if you pop 1 tire with a pothole you need to buy 4 new tires instead of just the 1 that popped ?
Just bought a 4th gen 4runner and the people were meticulous about maintenance. Every two years they would do the service Scotty shows here plus front and rear diffs. Simply amazing!
I changed the fluid yesterday on my Acura TSX, shifts like a dream and smooth as silk at 149,000 miles, maintenance is key
On all wheel drive vehicles no one replaces all 4 tyres in Australia.
You have to. It'll wear out the transfer case or tranny..unless you have the same exact tires..then yu might be able to get away with it
I changed both front and back diff.on my Jeep WK2 at 95k miles. I bought it used because it was such a clean vehicle, figured it could only help. The fluid on both came out looking brand new. Jeep calls for every 60k miles.
Might look OK but most of its properties is probably gone or failing
You did right to change it
I have never owned a car that had a drain plug in a differential or transmission! I have to pull the pan or cover to drain them. And have owned 86 cars in my life.
Nice demonstration Scotty. I will be doing the same thing to my BEAST. Thanks for the reminder too.
Thank you for the RAV4 AWD knowledge. So many of us are driving them, trying to keep them on the road.
It's for any awd.....because some people want a honda,or another awd
Scotty, do you ever do any repairs or maintenance inside a shop or garage ??? Always in the driveway? I’ve been a shop owner/mechanic for over 30 years and I have no desire to roll around on the ground. Great work btw. Knowledge is strength
like my mechanic friend, retired from workshop as he developed dermatitis from the grease and oil contact. Yet he would do it for friends at his home's driveway. He would probably do 1-2 jobs a week.
All-wheel-drive (AWD) vehicles need a lot of maintenance, as well.
My Subaru never did
Back in the good old bad old days, EP oils used to come with both a straight and cranked pipe
Brand new drain pan brand new gloves; have you ever done this before? 😂
How do you know it's new pan? And why use crap gloves for video?
@@psynurse you can't tell. Have you ever done mechanic work?
Scotty is in Texas might have something to do with how the pan looks @@Avengedsevenfoldrocks
I've been doing this for my niece's CRV. Started at 55000 miles and doing every 50k-only down side is you have to use the Honda Dual Pump 2 fluid and its not cheap!!!
scotty I did this on my 98 frontier Nissan four wheel drive, also a stick as well. great mileage improved
Subaru has front and rear differentials. The transfer case is integrated with the transmission. How often should the fluid be changed? The manufacturer recommends changing at 30k miles for severe service but no change interval for normal service. I did transmission and differentials at 60k.
Oh my Scottie, I thought the car had to be level???
great video, ut if your going to try this please make sure you get the right oil, unlike what i did when buying GL5 when i was supposed to put GL4 in, now i have to do it all over again. 😅
never changed any fluid, only added some and that since 1995 on the same car my volvo 740 from 1985
After my 2001 escape needed a new engine, I bought a 2007 jeep patriot at the ford dealership. It was about a year old with very low mileage. I bought a 5 year extended warranty from the dealer to cover me while I was paying off the loan.
I had the car for about 3 and a half years when my right wheel went out. I took it to a dodge dealer and presented my warranty for payment. The dodge service rep called and told me my warranty had expired. After calling the ford people, they said evevthough I I purchased the warranty, it was activated when the car was first delivered to the dealership. In essence, I paid for a 5 year warranty that began over a year before I purchased it. I was sh*t out of luck. I had to pay out of pocket. I will never bu a warranty again. It's just like you said, these are insurance policies, and there isn't anything more crooked than an insurance company!
Very simply question to ask “please highlight in this contract where and when my warranty ends”
I always buy the Platinum Extended Warranty thru Toyota Canada. The most years and kilometers they offer. The Platinum covers almost everything except wear items like brakes, tires, wipers. I feel it is cheap insurance in case something goes wrong. There are alot of electronics on today's cars and with the salt usage in Canada something is bound to go wrong. 2009 Toyota Rav4 V6 had to get 3 driveshafts to the rear replaced. That paid for the warranty in itself. 1st failed just after regular warranty. 3rd failed just before Extended warranty was up. Of course this is my opinion.
Bought a used 2000 CRV 10 years ago. It was making a bad clicking noise in the rear going around corners. Changed the rear diff fluid and noise is gone. Currently 212,000 miles with no noise.
I would bet that 95% of drivers never change their diff and transfer case fluids. If you buy a car new and only keep the car a few years this will probably never become an issue for you. However, if you buy used cars, it could cost you. Whenever I have purchased a used car I always replace all of the fluids right away just in case the fluids have never been replaced.
Scotty is definitely one of my favorite people! love what you do and thank you for all the priceless advice! you are the best!
Also DON'T forget the Transfer Case on 4WD vehicles & CV Joints, my previous FORD Bronco went through 3 CV Joints during the Warranty Period ❗
Look up the manufacturers recommend oil some of the newer transfer cases use Atf or a specific oil.
It’s funny how extended warranties know exactly what-not-to cover
Rule of thumb , If you buy an extended warranty the car wont break , if you dont buy an extended warranty you'll be fixing something every 3 months.
Hey Hey Scotty...I see you have a TN flag in the background of the Video...are you from TN? I'm here in Clarksville close to Nashville!! Thanks so much for the videos...I have learned so much about my autos from watching your vidoes that I am teaching my 16 year old son about his first car...you are like my favorite mechanic uncle I never had!! Much love from TN!!
I remember changing out the differential fluid in my uncle’s suburban after 156,000 miles. Compared to new fluid it looked very worn out. FWIW
If you take the fill plug out before you take out the drain plug ...it flows out much easier and quicker...
I just bought a 90' Nissan Pathfinder 4*4 and been sitting awhile that's the next thing I plan to do had to change several old GM truck rear diffs love the videos KY ✌️
How is it that the tires are already different size (as the fronts are severely worn) and it hasn't ruined the all-wheel- drive system ? Why wouldn't putting two new tires on the back and moving the back to the front be be the same or better than the current setup ? Your premise makes no sense.
Just changed the manual gearbox oil in my mondeo...pig that was to do, lca and subframe in the way, but i did it Scotty. Whoop whoop🎉🎉 used an hex/Allen key inserted through a spanner to tighten everything back. Not much space for anything else. 15 year gear oil that came was junky black and dirty.
Yup i change all fluids in my 2014 ford f150 every 60,000km runs like a dream ❤ oil changes every 5000km
Thank you scotty for this channel. All your knowledge u shared will be avaliable for ever and that's awsome
You are right. Great words.
Scotty the most honest mechanic 🧰🎉
Can i make a AWD Drive to a FWD?
Thank you for all your instructive videos Scott
I can't thank you enough for the videos that you do!! I love the videos and the information you share! It's so helpful! Thanks again😊
Park it on a flat surface & then jack it up so it's no longer flat.
Thank you ❤, Scotty! 😊
That was some damn good advice. Thanks for sharing.
I'll tell ya another trick... When I put differential fluid (in which every vehicle I ever owned) I'll put stop oil treatment in with it also (never put in motor) makes it so slippery in there you WILL notice a difference! And especially in a standard transmission... Makes the gears slide in shifts so nice. I've done this every one and haven't had a problem. In fact guy I knew his truck once sounded like the rear end was gonna fall out.. drained the old out filled it with stop oil treatment only.. it quieted down and he still drives the truck to this day never changing a anything.
2:30 Am I the only one that LIKES the smell of gear oil?? :D
Please listen to what Scotty says here. I had the misfortune of buying a 2011 Toyota Venza V6 AWD used. I bought it with 80,000 miles. At 83,000 miles, the rear differential completely went out. As it turns out, the previous owner never maintained it. $5500 later, I had a new differential. That was 20,000 miles ago. Everything is great now, but you better believe that come 110-115,000 miles, that differential will be getting new gear oil. Maintain your vehicles, folks.
Torque spec nice n tight
I like using the Motul 300 75W-90 GL-4/GL-5 gear oil in both my 6-speed gearbox and differential on my 370Z. I top off the levels at 10k mile intervals and change it at 20k miles. The Motul is a GL-4 and GL-5 API certified oil that has extreme pressure wear protection for hypoid bevel gears on differentials but doesn't use harsh sulfur and phosphorus compounds that can be corrosive on soft metals and seals. The Motul is more expensive but it does perform very well, especially under high temperature, high rpm use.
God, please bless Scotty and his family and all his grandchildren for all Scotty's kindness to people around the big World.
I vibe with his UGH when poppin these plugs because some of these be TIGHT! Lol
If you have a manual transmission, it's the same process as a transfer case or rear differential fluid change - only the type of gear oil is different.
And make sure you can fill it before you drain it! Haha 🤣
Those Dreaded TransxaxLes... Storys; Listen uP🆙 , Lol.
Great tutorial Scotty.
The 5 gallon water conditioner is a good idea! Got a bunch of em laying around! Haha
One of my concerns for doing self maintenance is that something may break off, etc. and now the vehicle has to be towed AND repaired AND maintenance. Gotta know your limits. ha.
Replace all 4 tires even on part time all wheel drive cars?
I love ❤️ how Scotty surrounding Clean, it reminds me of myself doing that same work in a clean place.
Thankx Scotty i most likely need to do that.
I have a five year old 4X4 Isuzu 3.0 liter diesel. It only gets serviced at an Isuzu dealer. The last time I got it serviced the mechanic asked me to look at the coolant. It was nearly clear. He said that when the coolant loses the color, it should be changed. The coolant wasn't that expensive so I had it changed. My Isuzu is the best vehicle I have ever owned. No problems at all and it still looks like new. It is more economical than my wife's gasoline car with a tiny 1.5 liter engine.
Never stop posting videos!!!!!!!!
Scotty ..
Still doing oil changes when he really doesnt need the money .
Scotty mentioned an
Important Tip about loosening the Fill plug first BEFORE you drain it .
We are already in middle of July!
I think you should use a torque wrench to snug those bolts. But hey, what do I know?
Rotate from time to time 😂
How can you say four tyres have to be bought together to keep all four wheels the same diameter? The front tyres clearly wear more quickly than the rears so they'll soon be a different diameter, which you say is unacceptable.
You rotate your tires every 5000-10000 miles. Keeps all the tires the same...until, hopefully, they all wear out at the same time. The issue is when you have 50,000 miles on a set that has 20,000 miles left, and you blow a sidewall out on one tire! You have to replace all 4. That happened to me on my 2016 Legacy.
I wonder how large a staff Scotty has to come up with these daily videos.
Pretty sure it’s just him - I was thinking the same but he makes it clear he does it himself - possibly one or two of his children may help with editing or something but 3x a day posting videos, he’s a beast! Funny thing is, he’s not in it for the $, he is literally just in it providing information - what would we do without him? No one else is giving us this info about vehicles and stealerships these days!
He does it by himself
