Steering problem

[Davy]

My '95 850 2.0T5 keeps steering to the right after several checkups. When i
let go of the steering wheel it's immediately gone where other cars i've
driven on the same road keep goin straight ahead for a while. I know
it'll always go a bit to the right of the road but this is a bit too much
if u ask me and nobody can find a problem. Other thing is the steering
wheel starts shaking when driving around 130-150kmph which i think comes
from the rims. Even when the wheels are ballanced they do it again after a
while. I'm thinkin of buying new ones in a while though.
Can those 2 problems have some connection or not?

This might be trivial, but does it do it on all roads you drive or just a
certain road?
Also I might be tempted to switch wheels and tires from one side of the car
to the other... both front and rear. See then if it pulls to the left.....

check for uneven wear on the tyres, this can easily be eliminated by
swapping the left wheel with the right one and if its a wheel or tyre fault
the pulling will switch from one side to the other........use this method
for testing only as you will undoubtably have directional tyres fitted which
cannot be permanently switched to the other side.......
the vibration at this speed also sounds like uneven wheel balancing, these
alloy rims are harder to get right than the older steel rims so make sure
its done correctly.......

Don't forget that the 850s are Front Wheel drive cars and need the rear wheels
to be tracked as well. Generally high speed wheel wobble is caused by imbalance
of the rear wheels. I would also look to the state of the suspension bushings,
wheel bearings and engine/gearbox mounts as well as the subframe mountings.

Cheers, Peter.

"Bad" radial belt will cause pulling described. Crossing wheels
described above is a good test. This could cause vibration.
Also, alloy wheels can warp or get bent which will produce high speed
vibration, even when tires appear balanced. Examine tire/wheel
carefully on balancing machine for eccentricity. Remounting tires can
help but may need to replace wheel(s).
