Rear axle bushes

As it was a nice yesterday - well not wet and windy - I persuaded myself to go out to shed to re-assemble my rear hubs with tapered shafts from Roger, when I noticed that the bush in the axle was missing from the near side of the axle. Looking down the hole I could see it, so it must have been turning with the half shaft for goodness knows how long. I poked a bent bit of wire in and hooked in back, thinking if it must be loose fit in the end of the axle and just slip out, but no. Luckily I have the technology to extract it, which took some pulling so it's certainly not even a sliding fit!

So my question remains - is this a common problem? If not, any ideas as to what could have caused it to migrate inwards? It's not a tight fit on the old shaft so I wouldn't possibly have pushed it in when I last assembled the axle. The off side is OK.

Got the pic Tony and am enjoying being able to see these again. No clue what your bushing issue is but trust knowledge from others will flow shortly.

Attachments :Thanks Rick, as my messages don't come back to my in-box from the group, although they do on another of my groups, it's good to know it didn't get swallowed by yahoo....

Attachments :hi Tony - it's not a common problem, but occurs because the half-shafts flex a lot, and come into contact with the bushes. This heats them up, they expand and jam the shafts: they then rotate in the axle and get loose, before cooling down. The best solution is to forget them and fit lip-sealed hub nuts (available from your favourite MG retailer).
Your solution is certainly ingenious, but most people either leave them in, or remove the diff. to hook them out from inside.
