[xk] 120 Front suspension

Lower Steering swifel:
I bought a rebuilding kit but it has only:

  • a new ball pin with nut and rubber seal
    and a socket for the ball made from a plastic like
    material. I find no way how this part should fit in
    the old ball socket cap, which still has a (worn )
    layer of the original ferosbestos material.
    How much end play in this unit is tolerable ??

You need to remove the old ferrosbestos cup before you can install
the new cup… You will probably have to “dig” it out…
Clean all the metal pieces and reassemble with a coating of grease
on the ball pin and in the cup… don’t over do it… The “End Play” (Float)
between the Ball Pin and housing should be .010"… There are shims
required to achieve this end play (Float)…
Once assembled and installed, then you can grease the ball joints as
you normally would.

Tanks to all the people who responded to my offside/nearside question.
I have almost finished the front suspension and steering and there are
only
two things remaining to do:

  • upper ball joint: I could not find a replacement so I decided to use
    the
    the old one. It is not worn out and I did not feel any endplay. Is this
    part
    critical, should I check it again ??
  • track rod end rubber bushing: I could not find a replacement rubber
    busing,
    so… see above.
    Good night

Peter H;
The upper ball-joints are available from most of the major XK
suppliers… Check with some in the UK. And, Yes, Ball-joints, either upper
or lower, are very critical… General rule of thumb… if you can move the
ball-pin easily by hand, it’s too loose. It needs to be very tight in order
to handle the load without play.
On the Track-Arm bushing… those, I don’t believe, are available…
but one can replace the “bushing/pin” as a unit… the “new” ones press in
the Track-Arm. There are two different sizes… one for the XK’s and the
other (a larger unit) for the MK VII’s. I don’t have the actual sizes
handy…
If these above items are “repaired” incorrectly, you WILL have
problems with your front end…
As the advert says… “Pay me now, or pay me later” ;-}

Charles…
Is this after the lower ball is installed in the spindle housing, cap then
attached, but before the taper on the pin is fitted to the lower suspension
arm?

Jerry;
No, this would be for checking the wear on used “factory
assembled” units like the top ball joint…
A correctly rebuilt/shimmed lower with it’s .010" end float will
move fairly easily after it’s assembled.
