Does anyone know how Jaguar actually decided what size spacer to use? I've replaced entire hub last year for the MOT because excessive wheel movement at 9-3, the car failed the MOT on the same thing this year, was a surprise tbh but the forward tapered bearing was indeed shot. I quickly fitted the old hub bearing(one was still ok on it) and all was well until I've put everything back together. There was still some movement.
I've looked into it closer and realised that I was missing the adjustable spacer at the front and it was only fitted at the back which meant that the front bearing was fairly loose at its race and probably why bearing got destroyed.
Thing is, I can only ever remember having a single spacer at the back on my current Jag and previous two(and I've replaced bearing on both of them on one side)( and now I'm pretty sure this is incorrect and the spacer should be used on both sides. Luckily I had the spare spacer on the old hub so fitted that at the front, grinded down maybe a third of it with an angle grinder so the whole hub fitted tight in the wishbone and now I get zero 9-3 play. Car of course passed the MOT with no issues.




Now, I'm wondering how the heck Jag decided what size spacer to fit here, I just squeezed the bearing into the hub with my fingers and grinded the forward spacer so the bearing was tight in the race on both sides and the spacer was flush with the pivot pin on both sides too.
I imagine not exactly correct way to do it, even though it worked!
I'll probably remove the other side hub and check if the spacer is there too.
