neilc Posted September 7, 2019 Share Posted September 7, 2019 Ive got a bad vibration which I'm assuming is a the rear prop , I've taken it off , replaced ujs and I'll put it back in later , when I removed one of the cups there was no sign of any needles , not even the shattered remains , not even black dust , they were there when I installed them ! Have they just broken down ? Where would the fragments go ?weird because 2 of the ends were perfect but the opposite end to this one had a few broken needles . Thanks .

steve b Posted September 7, 2019 Share Posted September 7, 2019 Were they all greasy when you took it apart ? What brand was it ? Was the oil seal ring still there on all four pins? cheers Steve b Quote Link to comment Share on other sites More sharing options...
neilc Posted September 7, 2019 Author Share Posted September 7, 2019 Weirdly yeah ,they were all greased and seals still on , the only thing I can think is that they were ground down so bad that they disintegrated! Quote Link to comment Share on other sites More sharing options...
Snagger Posted September 8, 2019 Share Posted September 8, 2019 That’s exactly what happened. They’ll have been broken up and spat out, and once it started, it’d have progressed quickly. The root cause would be good to know. Blue box, unbalanced shaft, wrong grease or inclined diff pinion axis would all be likely causes.

neilc Posted September 8, 2019 Author Share Posted September 8, 2019 I can rule out blue box ! 1 Quote Link to comment Share on other sites More sharing options...
