Nuts: Are these "one-time use"?

[Packin4]

Getting ready to order some parts and can't recall where I read this but... are these "one-time use" nuts on '87 Carrera:
1. Trailing Arm nuts (near trans tunnel)?
2. CV Axle nuts (32mm, outboard CV, not castle nut)?
Thanks in Advance!

I have been told the CV joint/axle bolts are to be replaced after each use.

On my 81SC and 87 930, I reused the CV bolts all the time. As long as the heads were screwed up. YMMV.

CV nuts? Do you mean bolts? I would not reuse them. They’re cheap, why risk it? Not sure of the size for your car, but on a ‘77 they are 45 mm.

I'm talking nuts (not bolts). Specifically the 32mm axle nut (at the end of the outboard CV axle) AND the nuts at the trailing arm bushing (near the trans tunnel).

Big 32mm central nut is reusable. Torque it to spec.

stub axle nut is reusable, if you wanted to allay any fears, put a dot of loctite blue on the threads.

I agree, as long as the heads and threads are completely undamaged there is no need to replace them.

If you have the Schnorr serrated washers, they can also be re-used if undamaged. However they can only be used a few times before they have damage and need to be replaced.

Anybody know if the trailing arm nuts (22mm socket, near the trans tunnel) are one-time use? They appear to be the "self-locking" type.

Those are reusable
