1990 Jaguar XJS Front Bearing Replacement

The soft line is attached upside down, JJJ. However, if it is long enough to not be stretched at all when on full lock AND full suspension travel, it will be OK. If you change it round, you will have to make a new hard line of course.
Shims: read carefully:
Shims: read carefully:
- The steering arm is attached to the top of the upright, above the inner end of the stub axle
- The steering arm is ALSO attached to the upright TOGETHER with the BOTTOM caliper fixing bolts.
- This bottom caliper bolt goes: a) through the arm, then b) through the caliper, then c) through into the upright (as shown by the lockwired bolt in the photo below.
- Because the top bolt of the steering arm goes into the upright, and the bottom caliper bolt goes into the upright in a different plane, it is possible that the two bolted surfaces are not exactly parallel to each other.
- To ensure that this possibility does not result in a permanent bending moment on the steering arm when all the bolst are tightened, you have to insert a shim between the arm and the caliper to take up any space that may be there when the top steering arm bolt is tightened.
- So the procedure is to a) loosely insert the top caliper bolt not quite even finger tight, then b) loosely insert the bottom bolt through the arm and caliper into the upright but not even finger tight, then c) do up the top steering arm bolt tight, then d) tighten up the TOP caliper bolt, then e) try a feeler gauge to see if there is a gap between the arm and the caliper on the lower caliper bolt!
- If there is, get shims to this thickness and insert them, somehow into the gap!
Damn Greg. Amazing post and I will follow it...
I'm posting a photo. Is the shim the area I circled and,,, it goes on the OUTSIDE? I would have thought that it would be between the first and second layer of the arm and caliper combination. I can't even understand what effect a shim would have way out there so close to the bolt head.
But, ok!
Finishing work now. COViD mess has me on 3ed shift. Home to get some zzzzzzzz's. Talk soon!

The inner RH bearing looked pretty good. The RH outer bearing roller,,, not so clean. The inside of the race pretty spotless and the outside rim, not so clean. A bit "sticky" when trying to roll it between thumb and forefinger... The stub, on the outer, had a couple light groves... I think I'll have to live with that a while.
