Centre diff issue and questions
Posted: Fri Oct 04, 2019 11:46 pm
The patient: 1999/2000 RX Liberty wagon (EJ251) 5spd manual - aka, Basil
Issue: swapped in second hand gearbox (pick a part special!) only to find the vehicle now has a wobble like feeling from the front left when under acceleration, becomes worse with heavier acceleration. All other times the vehicle generally feels unsettled.
The other issue is that I have that totally awesome catch-let go-catch-let go feeling or experience when turning tight such as when performing a U turn.
Questions:
1) can a stuffed centre diff create the issue with the front end that I’m experiencing?
2) can the viscous gel stuff leak from the viscous LSD housing, and if so, what does it look like?
Question 2 was asked because after stripping down the old box that was replaced, Ive found a ball of what looks like silicone near the front diff area, grey in colour I think, and in between the drive and output of the centre diff is the same sort of material. It does seem like silicone but its just a real odd place to find it!
This gearbox has presumably done over 400k km now - if it hasnt been changed at some point. It was swapped because of a bearing noise and it was slipping out of gear (possibly due to shot pitch stopper rod and gearbox mount).
Upon rotating the centre diff it seems the noise is in the rear bearing. This centre diff is good so it’ll end up in the wagon either way - unless that grey material is the viscous gel stuff, then I don’t know what we’ll do...
