Differential Bolts replacement DIY: updated bolts
Well, I figured I'm seeing threads where people are saying "I had my local Indy shop change out my differential bolts" and while sometimes they get it done for free, there are other times that people actually pay.
This is VERY SIMPLE and even someone with little to no experience can do it with a little patience and 15 min of time. Total time for this DIY was 30 min for me, but that involved pictures and a bathroom break for both me and my husky (who is in the middle of being potty trained) Any questions, feel free to ask but as you will see, it's pretty self explanatory. Tools needed: - revised bolts (2) part number 23 00 1 222 891 - E14 Torx socket - breaker bar and 3/8" wrachet - two small extensions - swivel - torque wrench. Start by raising the car and getting the rear on jack stands. This is BY FAR the most important part of any DIY under the car. Sadly, we lost one of our members on svtperformance.com when the cobra dropped on him while changing a clutch. I use jack stands, wood under the wheels (if the wheels are to remain on. If the wheels are coming off, put them under the car toward the middle. A ruined set of wheels can be replaced, you can not!!!) and a floor jack next to me while I'm working. It DOES get in the way, but if the car happens to drop, the little annoyance won't matter so much. BEFORE getting under the car, give it a good shake to make sure it is sturdy. Put a block in front of the front wheels. http://i62.photobucket.com/albums/h8...r/IMG_1109.jpg These are the two bolts to be removed. They are E14 torx. http://i62.photobucket.com/albums/h8...r/IMG_1110.jpg http://i62.photobucket.com/albums/h8...r/IMG_1112.jpg http://i62.photobucket.com/albums/h8...r/IMG_1123.jpg Place the jack under the side to be worked on just like shown below. Jack it up just enough to take the weight off the bolt. This will stop the rear end from shifting when the bolt comes out and make the job that much quicker. It actually makes getting the bolt in/out easier as well. http://i62.photobucket.com/albums/h8...r/IMG_1117.jpg I had to use a breaker bar to loosen the bolts. Neither were loose. Once loose, I used this set up on the drivers side http://i62.photobucket.com/albums/h8...r/IMG_1121.jpg and this on the passenger http://i62.photobucket.com/albums/h8...r/IMG_1122.jpg Now this is why you use the jack. If you didn't it will look like this http://i62.photobucket.com/albums/h8...IMG_1116-1.jpg Not a big deal...just use the jack to re-align it again if needed so it looks like this http://i62.photobucket.com/albums/h8...r/IMG_1119.jpg Note: If you look at the hole, I think this might be what is causing bolts to break/back out. The hole is too big (at least on my car) and the rear end can actually move even with the bolts fully torqued. The two bolts next to each other http://i62.photobucket.com/albums/h8...r/IMG_1114.jpg The new one compensates for the play by eliminating the threads toward the top and it even tapers out a bit. This DID NOT eliminate the play, but reduced it considerably. The loud "clunk" when shifting hard (I have an SMG) has almost completely gone away. It is still there, but much less noticeable. I would highly suggest checking the torque periodically as I'm pretty sure these will back out too. And if they do, they will break eventually as well. With the jack in place, the new bolts will literally be able to go in by hand. http://i62.photobucket.com/albums/h8...r/IMG_1120.jpg torque the bolts down to 61ft/lbs. This can be a little tricky as most torque wrenches are HUGE. Use your swivel....It makes life so much easier! Drop the car and enjoy a quieter rear end under hard shifts!! Total cost was around $5 for the two bolts from my local stealership. |
Excellent DIY, good emphasis on the jacking up part.
However, people need to stop finding things wrong with this car because now I need to fix them :D |

Serious about finding things wrong with this car! It's getting ridiculous :lolhit: |
Just FYI you should not jack from or support the car by the diff cover. It's made of aluminium and the cooling fins could possibly get damaged or collapse. Definitely not made to support the weight of the car. Jack from the rear subframe, or if you must, the diff itself.

Very nicely done! Thanks for taking the time to put this together.

So are these bolts improved in anyway?

Change them out? Yeah, why not...it was $5 and will literally take 15 min or so. Necessary, no. I see keeping up on torque specs as more important. |
Thanks for sharing, :thumbsup2:
