Vibration through dash!

Sat Jul 19, 2008 5:47 pm

Ive got a vibration through my dash about 90 ish!
Doesnt really do it until then and doesnt do it over 90.
Normally i would say rear wheel ballence but its had new tyres front and rear two days ago, so im at a bit of a loss of what it could be!
Anyone else had this? Or know what it could be?

dannyboy, did you have bad vibrations before your new tyres were fitted?.

yeap! and... the front suspension feels like its made of custard tart!
You turn into a corner and you always have to corrct the steering demand!
Im at a loss because nearly all the parts on the cars suspension are or have been new in the last 3 years or so and every thing seems tight.
Just cant seem to figure it out as this is a fault ive never had on any of my E30´s

Just tried the car again its only speed related not revs!
And it only does it when you drive ing if you knock it out of gear above 90 and drift its ok!
So im taking it it will be the g box mounts even though they are new ish the g box coupling is ok so im at a loss

Had an issue with diff mount once but noticed it through the seat not dash, maybe worth a look though ?

Thats new as well!
Dont suppose it could be an innner ball joint on a suspesion arm?

Hi Danny,
Check your prop centre bearing at the same time and make sure that is all secure....

If you need a new centre bearing I have just had a new one fitted (that I got from Paul at Cotswold BMW) and the prop rebalanced at Firow Propshafts outside Oulton Park - absolutely fantastic job they did, and re-painted the prop as well!

as above i would say .

i have a wobble on mine that does what you say (goes when you dip the clutch and is not rev related) the only other thing it may be it tracking but the centre bearing may be your best bet.

haynes manual says how to pre-tention the bearing . but i cant coment how good the right up is as i only skimmed it enough to give up on it and wait till another day.
