Steering wheel shake on MK1 Sierra

Have you replaced the bulkhead bush for the steering column? To test, from under the bonnet, hold the steering shaft where it exits the bulkhead and try and lift it up and down, ideally there should be no movement, but realistically there will be some, but not too much..

Also anti-roll bar bushes to body wear.

It could be this. Swap the wheels around and see if things change. If the problem gets noticeably worse or better, this is the cause. You would be surprised how often you pay for wheel balancing only for the mechanic to give the wheel a quick spin on the machine. Next time make sure the machine reads zero before you let the mechanic take the wheel off.

I had a problem like this on a Sierra too many years ago to clearly remember, it turned out to be a bush in the front of the propshaft, I can't for the life of me remember the details, There was something just behind the front u/j in the shaft. A second hand shaft cured it if I remember correctly.

Thanks to MrCheerful, DP and r - I will investigate your suggestions and report back to the news group (for beneft of others) when I finally cure the problem.

Thanks again

the ONLY way to solve the problem is to do the following fit new front hubs fit new front discs fit new front pads problem solved everything else is just pointless unless you replace the outer track control arm bushes with some polyurethane items the steering column bush (lives on the steering column in the bulkhead) is a £3 item and a pain in the posterior to change but this just means that the steering wheel goes up and down when you shake it the propshaft doughnut will manifest itself in a vibration from the back/bottom of the car and can be easily checked by wobbling the prop to see if there is a problem with it

I find them easy to change, what do you do?

it's all the lying on the back in some bent position that does me in (broken back and all)
