Hi All,
Hoping someone could lend some ideas with relation to a vibration that I am having with my P38 diesel, vehicle has just turned 90K miles.
Problem I am having is that at around 50mph I get a vibration / shimmy through the steering wheel. I have recently put a set of 18" wheels and tyres on and I cannot be certain whether the problem is simply exaggerated through the fitment of these tyres or has caused it in its entirety.
On the 16" wheels, there was some vibration and shimmy but not as bad, but the vibration at 50 was not particularly noticeable.
I checked the propshafts and ball joints (upper and lower) and did not find any wear. I found a bit of slop in the steering joints so changed the drag link / track rod along with the joints, and also changed the steering damper. I hoped that this would fix it but to no avail.
I have checked the viscous coupling and this is all in order.
I am running out of options and patience. I have searched on the various forums and there have been numerous mentions of a similar problem but unfortunately no solutions.
As mentioned earlier, the wheels and tyres are relatively new and I am going to get them re-balanced at 3pm but other than that I can't think of anything left to do?
The only thing in the back of my mind that I thought might possibly cause it is that I know that the dual mass flywheel needs changing. It has been faulty for some time but apart from some "wobble" at idle it has not bothered me unduly. Is it possible that the problem could be related. I'm not ruling out the vibration coming from anywhere as from previous vehicles I know that the vibrations are transferred through the steering.
Any advice please? I am due to pick a caravan up on Monday with it!
Regards,
Dave
