In reply to a message from MikeSW17 sent Tue 1 May 2007:
Well, it’s not the wheel alignment.
Swapped the N/S front and rear tyres. Drove the car for a
few minutes no problem.
Returned and swapped the O/S front and rear tyres… OOPS,
on moving off the car veers heavily to the right, needs
several ounces of pressure on the steering wheel to pull the
car to straight.
So off to the local tyre shop.
‘‘Hi, can you do me a wheel align?’’
‘‘No, not on a Jaguar, needs special equipment.’’
‘‘Right, but I know there’s something wrong. I just want a
‘best effort’ set-up I can work from. Anyhow, it’s already
less than 150.8mm from sub-frame to ground.’’
‘‘Ok, well if that’s what you want…’’
The alignment was well off, toe-in ~8mm. Chap adjusted it to
roughly parallel - ignoring my suggestion that 3-4mm toe-in
would be nice - but then I couldn’t understand much of his
language, why should he understand mine?
‘‘Take it out for a drive, see how it is’’ (I think he said)
Much better, still pulling to the right but only needs
finger-tip pressure on the wheel to correct.
Under braking the pull to right vanishes, but is constant
under acceleration/constant speed.
Chap put it back on the ramp and got the inspection light
out. Showed me that the rubber round the bottom O/S wishbone
bearings was squeezing out round the bolt head - didn’t look
good compared with the N/S one.
All this for free - no charge (just the price of a pint or
two in the mans hand) - didn’t expect that from a
high-street tyre ‘specialist’.
Anyhow, problem diagnosed, not alignment but camber angle
which was suspected (by me and you lot), but I didn’t much
want to hear.
Any ideas how much changing the wishbone bushes might cost
me? My local garage guy started mumbling ‘‘oh, seized pins
big job, hard work’’ (he usually gets sad and complains he
didn’t charge enough for the last job) before asking me to
bring it back on Friday to get it on the ramp for a look.
Not too sure, but I think this job needs the front spring
compressor tool? I don’t think they have one…
Might take the car over to Surrey Jags tomorrow see what
they have to say.
I think I only need to do the O/S ones (soon) as after
swapping the N/S wheels there was no noticable change in
steering - although the N/S tyre wear seemed similar?–
The original message included these comments:
Continuing my investigations into tyre wear, I am looking at
the wheel alignment.
