Dear Panel,
Trying to sort a problem on my wife's MK1 Sierra Estate which is baffling me slightly - wanted to pick your brains. Problem 50 mph and then breaking causes the steering wheel shake (but only by a small amount - more irritating than dangerous)
I've replaced the lower ball joints, track control arms and bushes, checked wheel bearings and all ok.replaced the callipers and disks (calliper seized so replaced both and disk/pads at the same time). Still the problem occurs..
The steering rack is 5 years old (and 30 K miles), also replaced the track rod ends and front shocks at the same time.
Questions
1.. Could it be the pattern parts I replaced 5 years ago - anyone had a problem with a track rod end/steering rack wearing after this time - admittedly the short journey and parking wear belies the 30K ageing. 2.. Wheel balancing - the steering wheel doesn't wobble at speed - but could a minor balancing issue cause the problem ? 3.. Tracking - could this contribute ? Many thanks in advance for all adviceSydney
