That part is called a flange, and you do need to either chase it or re-tap it with a clean tap.

You'll probably want to replace the seal after disturbing it, and you'll need to fill the gear oil correctly.

I wouldn't use a tap and die set on it, get yourself a thread chaser kit and try it first and see if it holds torque..

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

The rear axle bolts came loose. I tried reinstalling new bolts and washers per the forum but the threads are boogers up and will not allow me to bolt up to the gearbox. I am looking for advice ? Should i tap and die the threads to make it work or should i get a new hub? I am not even sure what the part is called that axle bolts to on the tranny side. It is held on with a torx head bolt. Is there anything i should know about before removing ? Please help.

POST 2Original post

I wouldn't use a tap and die set on it, get yourself a thread chaser kit and try it first and see if it holds torque.. here is a example of a thread chaser kit. Amazon Amazon

POST 3Original post

Yea i would start with the chaser then move to a "bottom" tap if the threads r good. The bottom tap has less tappered threads and wont have to go through as far to clean them up. Also get new bolts as those may be stretched or damaged. Blue lock tight will be your friend when installing to insure they stay put.

POST 4Original post

That part is called a flange, and you do need to either chase it or re-tap it with a clean tap. Although you don't need a bottom tap, but if you have it that is fine. Buy new bolts. It looks like the internals are all messed up. They are hard, grade 12.9 so not everyone local will carry those and they have to be specific length or they will interfere. Do need to torque it to specs (81Nm) and if you really want it secured, drill the heads of the bolts and install safety wires. They will never back out again. By the way, your CV boots are almost gone and need to be replaced.

Thank you for all of the responses. I have ordered all new bolts and the 3 washers under them. I am fixing to order a new axle as well. I�m probably going to order the new flange rather than chasing the threads. My question is what happens if I remove the bolt in the center of the flange is that piece easily replaced or should I trailer this to a shop ?

From the drawings on autoatlanta i think it just slides out. U may loose some fluid? What year is your car. From the drawings i think the only trans with a center bolt on the flang was the limited slip versions. The standard rears have an internal clip.

POST 7Original post

That looks like a ZF automatic so I'd guess a Mk1 car.

I have a friend who would refer to your situation as "fat wallet syndrome" Chase the threads. Replace the bolts. Unless the boots are torn or the CV's clacking, don't bother changing the shafts. Removing the flange from the trans means potentially opening up a can of worms. You'll probably want to replace the seal after disturbing it, and you'll need to fill the gear oil correctly.
