Thanks for the video. It will help a lot when replacing the dif. The dif weighs 77 lbs. A bit heavy for me. I gave it a try. It is a challenge for a more mature fellow to do without a lift.
@@chuppositybuddy I need the 3.45 ratio, 2014 rwd, 2.5 L, share the link where u found it. Also, i found some 3.45’s but they are for AWD. Are those compatible with my RWD vehicle?
So hard to find a differential for this car. currently working on a 3.6 ats with a bad diff. We're going to try and fit a diff out of a ct6. I think the axle cups just have to be swapped over from the old diff. Gear ratio is the same as the ats and the dimensions as well. I'm going to make a video if it ends up working out
Can't find em b/c GM ran out of it's own spare inventory - b/c of.replacememt rates. And the component maker stopped making it. Dealing with XTS-4 rear dif & drive shaft replacement now.
Does the main shaft have to be in a certain position when you bolt it back to the replacement diff and same question with the cv shafts or I can just bolt in
I have a 2014 ATS 2.0T Performance Automatic. I have noticed that my differential (the non-limited slip version) has that wet look. My research indicates that is a leak of some sort (gasket or seals). The cause can be a clogged vent screen. Anyone know how to clean said vent screen?
Been looking for weeks looking to find one that is 3.45 gear ratio with out any luck. Any suggestion on where to look ? LKQ has nothing in their inventory
Great video and super helpful since I am about to embark on this adventure myself. I have a 2015 3.6 AWD Luxury and I didn't really notice any in the video, but did you run into any gotchas? I had to get an aftermarket diff since I cant even get ahold of anything else and that alone makes me nervous, if it will even work out of the box or not.
Excellent video! Did you consider having someone rebuild the differential? I see a post below where someone is looking for the parts - are they really not available?
Balls, sound like I get to do this next. Maybe I can replace the bearings. Thanks, dude. It looks like most of them are 3.27 ratio and open for AWD and posy for 2wd I don't know if that helps
My pinion bearing is smoked too. I just opted for a new differential. Couldn't find a dealer diff, so I opted for a 3rd party differential. Hopefully it works.
@@samg2953 I replaced the entire assembly with a differential from Mad Hornets. It worked out perfectly and I have had no issues so far. I drive fast, but not hard and the differential held up well. All I have to say is, make sure you do the proper break-in procedure for a new diff and get that oil changed every 500 miles. Do that twice. After the second time, you're good after that. The differential oil will be black when you first change it out. As long as there isn't any excessive shavings, you're golden.
@@XsaviXander the carriers the most expensive part right about 1000$. After buying that i also need to purchase the other parts to complete the assembly such as seals and pins ?
Supposedy, metal shavings are causing the noise from diff. The diff fluid is supposed to be changed every 40k miles. My diff on my 2.0 15 ATS started to make noise after replacing diff lube and replacing shaft seals. Also, the diffs are hit or miss on the ATS and CTS as well. I ended up ordering a new diff from ebay for $425, even my customers thought it was the brakes.
Do you remember how much you paid for the differential? Also, how long did it take you to replace it? I have a 2015 cadillac cts and I need mines replaced
I have 16 cts. Paid just over $900 for a refurbished rear differential since I don’t plan on keeping the car too much longer. A brand new one would run me just under $2k depending on quality of the differential. I would figure out the exact recommended part # from Cadillac or gm and then search for the part from other sites.
@@partsshooter Finally got it out, Ugh! The darn diff fell to the ground on my finger🩹. I have a CTS so it wouldn't come off with the jack holding it up cause the frame and exhaust was blocking me from pulling it out the shaft. I had to just let it hang, pull, twist and wiggle it to death for it to come loose then BUM! My pinky swelled up like the knot on your head but a little ice should fix it. I went ahead and got new hex screws for the CV axles cause I didn't wanna risk stripping those torx screws. Fingers crossed the new diff goes back in easily. 🤞🏽
I wanna say yes! From a logical perspective, if the gear ratio is incorrect, you'll likely get transmission and abs codes. The wheel speed sensors will be out of synch once in motion. They look interchangeable and would likely work if this was the 90s 😂 but with the technology today, things cant be interchanged so easily. If you do put a different gear ratio in, you'll have to be prepared to overcome the above mention. Probably could disable abs or get things recalibrated somehow if there's a tuner more familiar with this

WOW an actual replacement video with beginning ,middle and end great job man!
great work this job is alot simpler than I thought
Great video. Like how you filmed start to finish steps.

thanks - good info in this video. in 2024 there are many suppliers offering these rebuilt on ebay for under $600.
Can you please share a link, I need one that is 3.45 gear ration they are all $1000+
@@obaidatuli7778 Mine is 3.27 gear and those are in the under $600 range. Unfortunately the 3.45 best I could find is $988

The problem seems to be the vent on top fails and it builds pressure and the seals fail.
Very helpful video thanks!
Very informative. Thank you!
Very good N informative vidoe im having same issue on my 2015 cts 2.ot. i took it in to a shop, and they quoted me 10k .
They are very simple to rebuild. But I can't seem to even find bearing replacement kits for it. ?? Strange

@xchevyimpala69x did that work out for you ?
Does the main shaft have to be in a certain position when you bolt it back to the replacement diff and same question with the cv shafts or I can just bolt in
Sry about that wasn't sure if you topped it up , but what about my first question the shaft you can just bolt on any which way right
Is there any way you can show me the site you got it from I’ve been looking for one for mine for 3 months and I can’t find them under 1,900
What was that stuff you put on the tip of the new diff with the brush after cleaning it? does that part need something on it before installation?
I have a 2014 ATS 2.0T Performance Automatic. I have noticed that my differential (the non-limited slip version) has that wet look. My research indicates that is a leak of some sort (gasket or seals). The cause can be a clogged vent screen. Anyone know how to clean said vent screen?
Tools needed:
18mm socket
18mm wrench
E12 socket
15/16 socket
What is the part number for this differential or the build code?
Been looking for weeks looking to find one that is 3.45 gear ratio with out any luck. Any suggestion on where to look ? LKQ has nothing in their inventory
wow very good video mate ! does the cv shaft and the main shaft as a position or it can be bolt on anyway thank ?
None of those shafts are indexed or balanced to the diff, so you reassemble as they fit
Cadilac service center charges $4200 to replace

Video shows full replacement. I leave nothing out to my best ability. Replacement is straight forward
What would you say total time was? Seemed not bad.
@ayeomans1 I should state this in the video. I can't recall. But 3hrs probably. I work on an array of cars since
Excellent video! Did you consider having someone rebuild the differential? I see a post below where someone is looking for the parts - are they really not available?
It's noon serviceable
None
And did you refill l the diffeeential fluid on the ground or when you reinstalled it
Nope... Did it while it was out
