How To Build A Driveshaft

[@robertmason8341]

Great info and like the style of your videos you make, no music, no bs, just good and informative and with just the right amount of personality to not overdo it or go the other way and be too bland!

[@mountainsgarage]

Thanks! You made my day!

[@craigbuness5554]

Thanks Shawn for a good video. I agree with your choice of components, Spicer and Plymouth Tube.

[@michaelkennedy2528]

Loved Maine when I visited there a lot. Hung out in Portland, Bar Harbor, Old Town and Legrange mostly. Went Lincoln on occasion. Nice video.

[@jaywdub3356]

This guy is the best!! I wish I lived next door to him!!! Keep on doing videos bro!!

[@mountainsgarage]

Your welcome Neighbor!

[@andydurrett6222]

I love your channel. Fine craftsmanship

[@BigFun4Life]

Great informative video as usual,thanks for sharing your knowledge buddy.

[@ShopDogFabrication]

Thanks for the video, adding a turbo to my dart. Want to upgrade the stock driveshaft. 7260 joints not so good.

[@slayfan21]

been building my own for my jeep mostly from junkyard parts and new tube. i need to get me one of them tube cutters. been using a bandsaw and then v blocks to dial the runout out lol. slip spline style shaft tho

[@matthewperry6506]

Great video

[@fixingthingswithpastorbill3840]

Great job this is the same way I have done it for years, rarely ever had any problems “ I just did on one my channel then I stumbled on yours “

[@mountainsgarage]

I will check out your channel!

[@fixingthingswithpastorbill3840]

@@mountainsgarage thanks 😊

[@scottmock6743]

awesome video

[@rgi8426]

What about balancing? How do you balance your driveshafts?

[@kewlmanable]

Now thats saving money!

[@charliebardo6255]

Where do you order your Spicer parts from bud ? Was it Traction there in Maine or someplace online? Really like your channel bud very interesting. And as a Yankee living in the south it's a treat listening to a Mainer talk. I'm from Madison Maine but moved to Louisiana 13 years ago to make a living. I miss Maine but don't miss what the politicians have done to the state. Keep up the good work sir, I look forward to seeing your new videos. Even though you've contracted that LSitis affliction 😂

[@mountainsgarage]

I have purchased from Jegs, EBay, and Drivetrain America. Lately wherever I can find it.
Strange Engineering has billet weld yokes and that is where this tube came from. The next shaft might get the billet ends!
Thanks for watching! I also have small and big blocks. I used to put a big block in everything!

[@MHolt3573]

Thank you sir.

[@baby-sharkgto4902]

What part of Maine do you live in? I use to live in Northeast Maine, many years ago. I enjoyed this video! I went from a 2 piece steel drive shaft to a one piece aluminum and finally to a carbon fiber. Having them all I can say that the carbon fiber is easily my favorite because of how quiet it is, not to mention strong and less likely to vibrate at high speeds. I liked the aluminum too but they were very loud. The two piece steel that came with the car is excellent for extremely high speeds but not trust worthy with extreme horsepower/torque.

[@mountainsgarage]

I live in Standish, about 20 miles West of Portland.
I dream of a carbon driveshaft!

[@noampitlik2332]

I really like your dot.

[@davidreed6070]

Will all the billet transbrake valve bodys brake in 1st and 2nd. Turbo 400. I would like you to do a video and teach me what engages or disengages for each gear

[@mountainsgarage]

No you have to specify if you want 2nd gear launch. ATD is a good choice!
I did a TH400 video on how it works, but can always revisit the subject.

[@kevinholbrook7174]

That was a awesome 👏 video bud! What would you charge a person to build a custom driveshaft for me? I am in the process of building one of my dream truck’s and I will be lengthening the frame but I don’t know how to measure for a driveshaft?

[@mountainsgarage]

Driveshaft parts were in short supply, but are coming back.

[@TheAkstewie]

.120 wall what thickness on the tube?

[@goatsinker347]

That's one hilarious accent.

[@mountainsgarage]

What accent??

[@timdontwannasay5889]

I was tempted to build my own before but I'M DOING IT NOW! I have a question, because my mind doesn't seem to want to shut down. What would be the downside of using cv joints instead of universal joints? Seems like the timing would be less crucial and more contact area to apply the torque through.. I've been mulling it for a while and I can only think of maybe a few house power.(?)

[@mountainsgarage]

Awesome!
The CV shafts, at least OEM style, are definitely weaker.

[@timdontwannasay5889]

@@mountainsgarage 😬 ouch! I always thought their main weakness was full turn and full throttle.. Thank you anyway!

[@timweb1510]

I have a non locking RPC dipstick that seems to be popping out of the tube for my turbo 400. I can’t see why it’s falling out other than vibration. Really gets me mad with the fluid I see on the firewall and possible issues with it being open while driving. If I were to go with a locking Lokar should the “full” line still be like your earlier uploads where you place a screwdriver against the pan and that’s the line? Many times I’m not sure mine is full while hot and in gear but I assumed a little bit accumulated above the pan line? Thank you

[@mountainsgarage]

I use the Proform 66182 locking dipstick, BTE sells one just like it, probably others. It fits with the flexplate shield as well.
I won’t use a Lokar, most don’t have anything holding them in the transmission and the fill hole is too small.
Most come miss adjusted out of the box, but yes the fill line is even with the pan rail inside.

[@timweb1510]

@@mountainsgarage thank you, I did read questionable reviews on the lokar. It’s on a sbf foxbody and I don’t believe I can get a hard line/non flexible tube in there. Sorry, I should have mentioned that

[@johnbean2596]

@timweb1510 Take electrical tape and wrap it around the sealing area. Works great

[@user-ir4bl7fl7u]

I have a broken jeep cherokee drive shaft. If i use a stick welder i rent from home depot or a equipment shop what rods should i use and what voltage? Im trying my best to work with what i got.

[@firstielasty1162]

I really suggest learning that on something other than a driveshaft..

[@GeneralElectricCNC]

Do you ever take runouts on the tube before you weld everything up? Balance is an issue.

[@mountainsgarage]

Yes I have many times. The moly tube is nice.
No balance issues yet, except with store bought mig welded mild steel shafts that cost three times more.

[@royboy620]

Hey pal, what yokes are you using, cast or chrome moly? I know you mention the tube is moly but I didn't hear the yokes?

[@mountainsgarage]

I have done both. Hard to get anything for parts right now!

[@royboy620]

@@mountainsgarage do you tig the cast ones? I see they say mig weld the cast ones. I have both types of welders but would prefer to tig it up.

[@mountainsgarage]

@@royboy620 Yes I tig them.

[@kermets]

Shawn not sure of your Darts over the line rpm but the 60" driveshaft can only turn about 4622rpm until critical-speed
...funny that mild steel has a higher critical-speed

[@mountainsgarage]

Yes the safety factor drops fast much over 50” length.
Thanks!

[@hooligans_garage7465]

What filler rod did u use?

[@mountainsgarage]

ER70S2 in 1/8”

[@lars5671]

So is it not nessecary to balance them if they are buildt precicly enough?

[@mountainsgarage]

That was a tip I got from the chassis shop, so far no issues.

[@Thatcressidaguy]

Awesome video! Did you have to balance it at all?

[@mountainsgarage]

Haven’t had to yet.

[@Thatcressidaguy]

@@mountainsgarage oh wow that’s awesome! I suppose if you weld it all straight and do all the prep correctly it should be fine

[@mountainsgarage]

@@Thatcressidaguy The light chrome moly tubing and the TIG welding help. I learned this from a chassis shop.
Local shops use mild steel and MIG welding.

[@Thatcressidaguy]

@@mountainsgarage oh yeah awesome as! I might give it a try! Fire the tig up and get some chromoly tubing, only thing is here in Australia for about 1.5 metres it’s about $450

[@jasonjennings5833]

Do you know how to add links in your descriptions to the parts you use, or the place you get material? That would be handy.

[@mountainsgarage]

I usually try to mention it during the video, and approximate cost. Popular questions.

[@slayfan21]

is that the ridgid no 30 cutter?

[@mountainsgarage]

Yes it is! I should have given more info!

[@petermullin5387]

I see in a lot of the off-road videos they are using non greaseable u-joints because the cross I solid and significantly stronger.

[@mountainsgarage]

They are OK on a shaft that is part time. You have to maintain the solid joints, take apart and grease.

[@danielbuckner2167]

This must be slow speed off road or for farm equipment since it isnt balanced

[@mountainsgarage]

180MPH

[@danielbuckner2167]

Off of bbn purenluck. I prefer to rely on those with talent. But hey, good luck!

[@danielbuckner2167]

*off of pure luck

[@mountainsgarage]

@@danielbuckner2167 If you have a local shop that can build you a TIG welded chrome moly shaft that is awesome.
All of the “Pro” shops in my area only build mild steel shafts with giant MIG welds and washers tacked on for balance.
Name the shops in your area that can and I will buy from them.

[@danielbuckner2167]

If I were using g a shop I would but I was looking for a simple alternatives to use a long bed lathe which is the easiest if you have one(or a friend). I feel like I ask too much so wanted to lighten his load. I'm not going to blindly "give it a shot" with a shrug, just not my style. You do you if you feel lucky go for it

[@001rickster]

You need axi line machine . AA Wheel and Truck Supply omaha ne. I'll build you a driveshaft. Trucks cars heavy duty trucks agriculture, pto shafts

[@slowcountryboy476]

uhmm, I failed to see how you balance the assembly.

[@mountainsgarage]

I don’t, but you could.
The tig welded chrome moly tubing in lighter and more precision than a mild steel shaft mig welded shaft, that helps.
If I ever have one vibrate, I will build another. Hasn’t happened yet, 180mph.

[@danielbuckner2167]

Sooo... just dumb luck and if it vibrates you drop another 200-300!? Hard pass, I'll get mine on a lathe and test the runout. Hell kids in the 1960s at least tested runout on the car and that's better than luck.
