Resto thanks for the info I'll keep it in mind and check that area as well.
Bill there is some slop on the trunnion. I've ordered a u-joint kit, shim kit and okie bushing. The bearing at the back of the gearbox seems fine. The front yoke bolt wasn't all that tight either ( certainly not to specs anyway ). I've started to practice my cursing and swearing so that I'll be up to scratch by the time the okie bushing arrives. Cheers mate
