Hi Team,
I'm still playing around with trying to fix the nasty wobbles on my GQ, time is difficult lately.
I'm going to check out King Pin bearings next and I might just replace them anyway.
I'm not overly keen on just removing a shim like some have done.
The question I have is if I replace the bearings with the same brand which I assume would be the Koyo's (need to confirm this when checking them) would you need to bother with removing everything inside and checking the preload or would it be fine to just replace with new and go?

Bear in mind that even if you replace the king pin bearings, you would still need to gauge the tork with an assortment of shims. So, in my humble oppinion, if your current bearings are good (no marks, smooth turning movements) I would really just re-stack the shims accordingly to achieve the manual load.

Thanks mate, I understand the shims and preload so they sit nicely above and below and I understand the shims purpose of machining tolerances of the knuckle in the factory but if they are the exact same brand bearings replaced than surely the bearings are bang on with size and will match the shims already in place to suit?

It could very well be, but honestly, out of coincidence. I wouldn't count on that.
You see, if one bearing race is pressed a little less onto the knuckle seat, the shimming would be different. Bottom line is, shimming is the final adjustment on a king pin by king pin basis.

Eureka!
I finally solved the nasty wobbles.
Just replaced the panhard rod bushes and it now drives like a bloody dream!
They felt fine with no movement but closer inspection showed some wear and they were nolathane too.
Anyways, Its such a pleasure to drive now!!!

I made up this little tool today which easily removed and installed the bushes too.

Found a good extrusion that works well with the top radiator today from Clarky.
