Another weird steering/suspention problem
I got another one for you guys 
Maybe somebody has suggestions or ideas that can help. The situation is the following, I am having terrible vibration at right hander conres with more then couple degrees of steering angle when going anything faster then slowly. No noticable behaviour like that on lfet handers, nothing strange on straights, stable under braking, even handles when sliding into right hander but when going round corner it shakes strongly enough for uninformed passanger to notice.
We'll be investigating into that on next days but so far I have no idea whatsoever what could taht be that would give such symptoms only on right hand corners..

Vibration is a little bit weird, can't locate it really. Seams to me like inner wheels though. For me it's more like front by my mate a rallyd river says he feels it more fromt the rear.

Have you tried it back on standard TCA's ?
Also worth checking the steering rack where it comes through the bulkhead is fine.

No not the bearing - the rack. Is there any play in it ?
Inside the rack there is bearings and the one on the right may be worn ?
Really hard to diagnose over the net. All we can do is throw suggestions at you.
Are the top mounts okay / tight ? Rubber bushes sitting fine ??
Have you swapped the wheel onto the other side to see if it follows ?

when did it start jakub? was it after any work on teh car or after driving though a hole in the road etc..?
could be front wheel bearing, remember there are 2, an inner and outer, in a left turn and in a straight line it may only be really loading one side up, but when u turn right, the faulty bearing is being loaded and showing up as a wobble...? just anohter idea

I think I have to look further into bearing thing. Never had a bearing failure without this loud train-like noise.. hmm...

OK, so we checked everything.
First thing we fond out was that it's transmission related. On the throttle it's MUCH stronger and as it comes on boost it becomes even stronger with g-force rasing. It's felt stronger to the back but in tunnel area. First idea was pop=shaft support bearing but it wasn't that (we changed it). Now last idea is gearbox mount. It is soft and vibration can also be felt on gearshifter. Maybe it's moving a bit too much and making pressure on prop shaft or something. I'ma currently working on getting new one....

So far we tracked it down to gearbox mount failing. Vibration is comming from the transmission tunnel, just behind the seats.
