Just got it changed and its a changed car. Need to look at the speedo now to check my speed its so much smoother.

Funny when the mechanic I got to do it put it up on the ramps he said the shaft felt fine. He couldnt feel any play at all but I saw the sag and perishing when I jacked the shaft gently up myself. Sure enough the bearing support rubber is brittle, sagged, cracked and perished.

 

Thought I could change it myself but no way on ramps and jacks unless you've arms like ET and superhuman strength.

The garage told me it took 3 of them to refit my custom made exhausts.

Will post the piccys of the new and old one soon. This is a job needed on lots of Zs now.

3 hours labour. Huge benefit in vibration killed and transmission noises, whine etc all gone.

you had the propshaft centre bearing replaced?

Picked mine up yesterday after having the centre bearing done and the rear half of the propshaft balanced (first half already done - they're supposed to be done as a whole but weren't).

I think it's killed the offending vibration but need to wait a day or so to be sure it doesn't come back! Gio

I got both the centre bearing and the gearbox support replaced. Worked for me.

Didn't bother with prop balancing or anything like that though.
