I have a MY 1999 with 49k.
I get a vibration from the rear at speeds above 85-90mp.

I have done a cv cup swap and they were not pitted anyway.
The rear wheel bearings are perfect.
All the bolts on prop etc are tight.
The diff mounts look ok (no obvious leaks).
The rear calipers are new so not sticking.

I rarely go above 80mph to be fair but I want to try and solve this problem without throwing money at it but it costs what it costs.

I have done a search but it only really shows the CV cup issue

Thanks in advance.

 

Bent rim possible that's always an issue with me or maybe you lost some balance magnets on a rim.. Next I would try alignment

 

Rims are ok, just fitted some JDM BBS rims and it did it before I fitted them, alignment also ok

 

Just to bump this thread, Just had diagnosed the diff output bearings have play in them !
