[Fot] Inner axle shaft of IRS rear axle moving outwards.

[van.mulders.marcel at telenet.be]

I found just now that the big washer was touching the cover of the diff housing : there is a groove where these 2 parts did touch. So the rubber mountings had no function anymore. Maybe the vibration of the pinion/crownwheel has worked as a hammering (in the curves)?

Marcel, I just had my diff apart to replace seals and just to look around inside. I had to use a 20 ton press to get those bearings off the inner axle shaft; very tight. I'd check the tolerances on the shaft and bearing. You may have some wear in the parts. Pressing them back together took some force too. 

Loc tite has a product for holding bearings onto shafts, green I think. It may help. 


Hope this helps and good luck.

The inner axle shaft (right side) has moved out of the axle house by as much as 12mm, so far that a lot of oil has leaked after a race. 
The ball bearing has slided inwards on the axle shaft by the same amount (retained by the oil seal housing). Has anyone experienced this? Before? I noticed these bearings had moved a little, but never more than 3mm. In fact, nothing does prevent the bearing of sliding on the axle shaft, except the interference. 
Does someone know a fix? Loctiting the bearing on the axle shaft? Machining a groove for a circlip? 
Marcel.
