Today’s ’little job’ UJs
Posted: Tue Oct 13, 2026 8:35 pm
Decided I’d replace the UJs, bit of vibration at 30-40mph, slight play at both joints, nothing too serious but a job to do.
Done UJs on MGs and Triumphs but never a minor, can’t be that difficult, can it?
Diff flange bolts off, no problem. Spline off gearbox, no problem. Maybe lost half a small cup of oil, no problem.
I’ve a 12t press so getting the cups in and out is dead easy, right? NO! The joints are tapered and the press pushes the shaft all over the place, PO mangled the holes with a mallet and the cups were destroyed pushing them through. Pushing the new ones in with the press was overkill - literally and destroyed a new UJ. Back to my old trusted G Cramp method and all back together and working fine
‘‘Twas a job in more need of doing than I thought, vibration now gone!
