Slip yoke wear - causes?
Posted: Wed Jul 03, 2019 9:45 am
I've had a gearbox tailshaft oil leak since day one with every box I've tried.
My present gearbox had a new tail bush fitted and new seal last year but the leak persisted. I'm about to fit a new gearbox which has also had a new shaft bush and seal fitted and I want to try and cure this once and for all.
My attentions have turned to the slip yoke (the only thing which I've never changed) and on inspection this does show some wear but nothing which seems significant (no indent where the seal makes contact). However the running face where it contacts with the bush is polished and slightly ridged.
All my diff and engine mounts are good (diff fitted with TTR competition mounts) so what usually causes this oil leak from the tailshaft?
How critical is the fit of the slip yoke in the bush? I can pick up slight wear using a vernier caliper but it does not seem too bad.
I am poised to buy a new slipe yoke but have a feeling there is an underlying issue which will make this go the same way.
Any comments appreciated.
