    Interesting Problem No.2 - Steering Fluctuating Wildly

    I've noticed the steering at low speeds can be very erratic, occasionally and very suddenly swerving one way or the other, to the point where driving along narrow roads in rush hour can be a little unpredicatable to say the least... no actual incidents so far, but a couple of close shaves!

    Is this something to do with the variable power-steering? Or something more sinister...

    It could be 'tramlining'. A common side effect of many big tyres. On the other hand, is the tyre wear uneven, for example on the inside or outside of the front tyres. Do you hear any knocking or bumping from the front suspension. If you are able, try jacking the front wheels off the ground and try to turn the wheels left and right while someone holds the steering wheel still. Is there any play? Also check for play in the wheels by rocking them from top to bottom.

    Hmmm... sounds more like a job for the local Jag specialist (going in for a service today or tomorrow). There is a slight noise from the front nearside when I go over a pothole, a bit of a clunk maybe... I'll investigate (or rather, get them to!!)

    Thanks!

    Would you say that it feels like extreme tramlining?

    Do you have the same same brand tyres on each axel? Are they of equal wear? Are the pressures correct?

    I had a similar problem with my Rx7 and it was simply a case of replacing the front tyres, which, unknown to me had worn on the inside.

    Never underestimate the importance of your tyres.

    Not checked myself (perhaps foolishly!) but I got a nearside rear puncture on Monday, and when I took it in to my local tyre place he did comment that the tyres looked ok all round... except the knackered one! (£159 for a Pirelli P0 fitted). They're all Pirelli as far as I know (will go out and look in bit) but not checked the pressure...

    Are the Pirellis' notorious for the tram line effect?
