arm bearings all done, wasnt difficult really, just a bit time consuming, once i had the arm off, you wouldnt believe the play in the bearings, there was about 7-8mm of movement in them !!, the bearings had disintegrated and it had worn a giant chunk out of the swinging arm once the bearings had been ground away!, I had to beat the snot out of the outer bearing races to get them out as they were fully siezed in, I beat one of them so hard that i actually split the outer race and it fell out then, and the rollers in the bearings were just dust !, there were 3 rollers left shaped like rusty rugby balls and half the outer race on 1 side was gone, worn/rusted away, and the inner race on 1 end had cold welded itself to the axle tube and i had to slit it with a dremel to get it off ! But the new bearings went in easy, tapped them in with a 24mm socket and hammer, and its all done now, if anyone else does it, you can probably expect it to take about 3-4 hours per side, the difference it makes to the suspension is amazing too, it floats again like my old XM did on the back, the slightest weight on the back and it goes down, then pumps itself back up a few seconds later, very nice and smooth and noise free on the bumps ! I just wish i had done the job sooner, as i could see the back wheels leaning in a bit and it was creaking when the suspension moved sometimes too.
