vibration

[mattw1992]

Hello All,

Have a 1999 Olympic Edition. I get a vibration when driving around 40-60km/h, worse when not accelerating. Some days it will be really bad and others I will hardly notice it.

I have checked the engine mounts, driveshaft and centre bearing and none of these are the issue, also not tire pressure or wheel alignment.

I'm thinking it may be the transmission as when I put it into neutral it almost instantly goes away? any ideas what it could be and how to fix it, it's driving me mad. (pun intended)

Thanks

other bits

when was the tranny serviced
do you thing its a clutch/master/slave cyl or pressure plate problem if a manual

if auto maybe torque converter

broken or saggy rear gearbox mount

shocks or spring sag

worn steering rack

rear tortion bar braces on the rear

just for starters

Thanks, It's an auto. Will take it up to the mechanics to get them to check it out. As i said, when i stick it into neutral it almost instantly goes away. The idle seems a little rough also.

Just got I back from the mechanics, cv joints replaced. Is definitely better but certainly not gone.

Torque converter perhaps?

So they have replaced the CV joints, now i have a new/different vibration, it seems more constant, there when accelerating, cruising and braking. Any ideas.

What was this? rear wheel bearings?
