How To Replace Differential Mounting Studs
Can the two bolts that come down from the chassis that go through the "wings" of the differential be changed? The threads on mine are severely damaged. Please note that this ISN'T a question about the front diff mount
If they are not replacable, how can I solve this problem?

Bump. Mine is broke in half. I can get the nut back on, but without the washer/bushing piece that goes on first. Even then, I am only able to get MAYBE 2 threads. If anyone knows how to do this, please post about it. If it takes cutting a hole through the floor, I am ok with that. I just really need this fixed. I really dont think it is safe to drive around with only 2 out of the 3 mounts actually doing something.
There are a few other threads similar to this, and none have an answer.
Thanks for any help

A friend recommended that I cut the stud and weld in a new one. Find a parts car in a junkyard and if you can, hack it.
Sounded like pretty good advice, but I went to see if my threads could be saved. I cleaned out the threads with a die and the nut went back on without a hitch.
Man this was an old thread, I was amazed that I got no responses in 2 years other than yours!

Im amazed that after an hour of searching, I didnt actually come up with some sort of answer lol. I have a parts car, so I may just go ahead and cut it and weld another one on. I was kind of thinking that a small hole cut in the floor and I could beat it up out of there kind of like a lug/wheel bolt and replace. Guess Im not so lucky. I guess if anything in another 2 years when someone searches they will at least get an answer. Thanks for the help.

OK, so I priced it through a local dealership and they obviously have to order it but its $345.xx plus tax of course. Gonna look and see if I can just pull that piece from my parts car. Gonna have to empty it out though as its currently full of steel getting ready to be crushed... Ugh, what a pain in the ***.

OK so this took awhile but I finally got some pics of exactly how to do this the CHEAPER, and MUCH EASIER way.
First off, you must cut a hole in your floor of the trunk/hatch area. There is a very easy locating "bump" that is an oval shape that marks where the stud is. Pic below shows the hole size that I had to cut out of the floor (stud has already been removed in pic).
Here is the part once removed. I used an air hammer with a cold chisel bit to cut the spot welds on the sides and a drill for the bottom. Dont drill through the bottom of the cross member if you can help it. Once removed this is basically what it looks like:
I then welded in the new piece (pictured above, didnt think it was worth taking a pic of the broken one) into the location that it needed to go. Here is a pic of that step:
This is a pic of the underneath once its all put together. I also welded the piece that was cut out of the floor back into the floor. I also didnt take a pic of this as it was done kinda crappy lol. Im not the best welder in the world so Id rather not show off my lack of "skillz". All in all it took roughly 15 minutes to cut out the "parts" (good) one and another 15 to cut out the "bad" one. The another 20-30 to weld it all back together and bolt it up as it should be.
So there it is, the writeup on how to replace a diff mount stud if needed. BTW, the oval "bump" is on both sides of the car on the floor so it doesnt matter which diff mount stud happens to break or get stripped out. Good luck and enjoy!!!
