[xj] XJ6 front wheel alignment

Hello, this is Martin Mindling in SouthEast Ohio. My car is a 1987
XJ6 sedan.
Question is: The front tires are wearing on the inside - local
mechanic indicates that the car must go to a Jaguar dealership
because special equipment is required for front alignment.
Specifically says car must be clamped on a custom jig and placed in
a fully laden position to properly align the front wheels.
Does anyone know if a typical non-dealer alignment shop can handle
the operation? I am 100 miles from nearest dealer and do not want
to pay an excessive price for alignment. Springs, bushings and
chassis rubber are all new. Tires are Pirelli specified for the
Series III. Tire pressures are according to the book. Are there
any CD’s or specification downloads available for the alignment job?
Thanks very much for any advice, and helping to keep my old Jag on
the road (purchased new in 1987).
Regards,
@MartinJohn

The real world necessity for the “mid-laden” suspension setting tools has
long been debated. I’ve never used them on any of my three Jags and never
had tire wear, steering, or tracking problems.

OTOH perhaps if I had used the tools I would’ve noticed some
improvement or difference. I dunno. Maybe it’s the difference between
“optimal” and merely “satisfactory” results.

Make sure to check for worn suspension components as well.

Hi Martin,

Ever since I was burnt by a franchised fitting bay years

ago and my tyres wore out after 2000 miles I’ve done my own
wheel alignment and with great success.

With the Jag you first need to get the camber somewhere

near spec. There should be a tad of positive camber at the
front, but in the real world, near vertical isn’t too bad
(If by any chance you’ve still got negative camber with no
shims behind the top wishbone, your front axle is deformed).

Toe in can be fairly accurately set using a 2 metre

aluminium straight edge, the type masons use- simply hold
the straight edge flush to the tyre and adjacent to the hub
centre and mark with chalk the ground 2 metres in front of
the wheel,then the same behind. Do this both sides and the
width between the chalk marks, front and back, corresponds
to the specified toe in. The axis behind the wheels should
diverge by about an 2 inches and those in front should
converge by the same amount. Adjust the track rod ends
accordingly.

I'm not having a go at garages, but it seems to me that

if they don’t have a computer program with your car’s spec.
built into it, then they’re lost. it’s not ‘rocket science’
even if they want you to believe that it is!

Any allignment shop can handle this, Marty - as Doug says; the setting
links is for
very high precision…

…which really is the put-off for allignment shops; having equipment to
measure minute fractions of degrees - they are ‘uncomfortable’ with
‘about’. Part of this is that other suspension anomalies, like sagging
springs, may have undue influence without the setting links. They
should, however, be willing to check the allignment to identify problems

  • including slack in joints that require rectification. No reputable
    shop will adjust allignment with slack joinery or suspension faults, and
    may hesitate if they are not sure of specs…

Never had a problem with my local tyre fitting company. I’m
guessing the software they use has the specifications for
unladen alignment so maybe it’s just a question of going to
a different company.
I suspect some places are reluctant to get involved when
it’s a case of shimming things rather than just screwing
things.
I get my alignment checked annually, it’s a good way of
picking up any changes due to wear which can sometimes be
tricky to spot, and is certainly cheaper than having to
change scrubbed tyres.
As for the scrubbing on the inside, I was told at one tyre
fitting establishment ‘‘yeah, they do that’’, hence my change
to a different company. No problems since.–

NoT so, Martin. Any good alignment shop can do this alignment on the Series
III car (Virtually NO Jaguar dealer will now have any special equipment to
do alignment on these cars and the vast majority will send the car “out” for
alignment anyway. Do make sure that the tank is full of fuel for the
alignment.

**You say that you have Pirelli tires “specified for the Series III” - if by
this you mean that you have the (awful) Pirelli P5 tires, I respectfully
suggest that you get rid of them ASAP. These tires are long past their “sell
by” date and were not good to begin with; if you are having a problem with
the car pulling to one side then the problem may in fact be caused by those
Pirellis (in fact by a number of different Pirelli models) which are
notorious for a “belt shift” before the tread is half worn. You can do a
simple test for this by switching the front wheels from one side to the
other. If the car now tracks straight or pulls to the other side, the tires
are the cause of the problem. I have “cured” the issue of pulling to one
side on Series III cars several times by doing nothing more than removing
the Pirellis and installing Michelins :slight_smile: .
You may, of course, also have an alignment problem.

In reply to a message from Dr Gregory Andrachuk sent Mon 18 Jul 2011:

Wear on the inside or outside of the tread is more likeluy, but not
necessarily due to improper toe in. Excess inside wear suggests toe
out is too much. It can be measured by a simple track rod made from
scrap material. Compare center to center half way up on the tire’s
tread, fron to to rear. 0 or just a tad less on the front measure
to the rear.

Or, a string from the center of the rear wheel to the front edge of
the front weel. Note the deflection.

Caster and camber wierdness is usually due to worn or bent parts.
Excess positive camber will wear the inside of the tire. A bubble
level can detect it. Apply vertically in the center of the wheel,
from ground up.

New tires in lieu of dinosauers make a world of difference, I know,
mine is a lot nicer with it’s new shoes.
