xjr v8 tramlining

[alanmercer7]

I have just bought another xjr v8 1999, and the big difference from this one and my last one is the ammount of movement and bouncing off road markings, I have had the tracking checked -ok, but the tyres are all needing replaced,could this be the reason, or something else -help please

Steering damper is the next thing to check after tracking, AFAIK ?

I have the bbs milans which I think come with slightly wider tyres has never tramlined. If it needs tyres try that first

Thanks for both of your replies. What is the steering damper,and what does that involve to sort. I am getting new tyres on this coming week

Lower wishbone bushes and lower ball joint are the common causes of that, is a thread on here for an XK with the same fault.

Steering dampers are fitted to performance motor cycles, there is no such think on a car.

Worn tyres masively exagerates any camber sensitiveness of any car, so you might find that with new tyres fitted the level of tramlinging is reduced to an exceptable level.

If not look into having the wishbone bushes and ball joints checked/replaced.

I thought you could have them on 4x4's, specifically defenders with power steering...didn't they have a steering damper so the wheel doesn't whip round while you are off road?

Thanks again for your help. Paul I hope the new tyres sort the problem,if not I will get the bushes and balljoints checked out -sounds expensive

An independant jag specialist reccomended I had the steering damper changed at the same time as the lower front suspension mounts to cure this problem (6cyl. X300). Something to do with that way the steering rack is mounted? I never crawled around under the car to investigate for myself, sorry if I'm repeating duff information.

mr.Tame Technician, You were spot on -it was the lower balljoint causing the problem , Thanks for your help -great forum
