Hi All,
For weeks now I have been trying to eliminate front wheel wobble/vibration from my late 85 oval-dash 944. It is fitted with Avon ZV3s, and displays at times alarming shaking at the steering wheel, at speeds varying from 60mph up to nearly 90mph. The problem is not consistent, though, on occasion being virtually non-existent, but then a few miles down the road returning with a vengeance.

The rims are Fuchs alloys, 7x16, fitted with 205/55 16s, pressures 2 bar ( 29psi ). They have been balanced 3 times in all, once by fitting to the balance machine with studs/nuts, rather than using the centre hole. All alignments etc have been double-checked, and none of the wishbone bushes look shot. It has no play in joints or wheel bearings. On smooth acceleration up through the gears, no vibration occurs - it is only when cruising at a constant speed.

It is the erratic nature of the problem that is so puzzling to me. Does this sound familiar to anyone out there and, if so, what is the solution please ?? All/any help gratefully received, people ! Cheers.

possible sticky brake caliper which will grab the disk and cause it to heat up and warp slightly, this sounds like a very good candidate due to its intermittantness.

sounds like a worn wishbone rubber to me

? Do you mean the balljoint, or the rubber bushing where it joins the body ?

I have just had a similar issue, although not so severe, with my 968. It turned out to be old tyres that had gone out of round from standing for too much of the time

How old are the tyres on your car?
There should be a 4 digit date code somewhere on the sidewall.

I had a similar issue with my old Lux. It my case it was the steering uj tie bar.(i think that's what its called) the part that passes the exhaust manifold. On the early cars they didn't have a heat shield and the joints would simply burn all the grease out and ware out.

Hi

Did the steering feel heavy too?
