[Mg-t] Axle or Differential

[Stuart C. Keen, Jr.]

While in my driveway yesterday, I started the engine, then placed the TD
into reverse - resulting in a LOUD BANG and no movement. Jacked up the rear,
and with engine running, put transmission in gear. The drive shaft appears
to be rotating properly, and universal coupling to the differential seems
good - but neither rear wheel rotates. In fact, with engine off, I can
freely rotate both rear wheels. Previously, there was always considerable
drag and it was difficult to rotate either by hand.

What has snapped or broken? From this layman's point of view, it is either
the differential (ring or pinion) OR the axle.

I cannot pull either of the rear wheels outward which I suspect might be
possible if the axle was broken (or is there something preventing the
outward movement?). Also, if it was the axle, then would BOTH wheels be
affected, not just one?

I am looking for some enlightenment before I drag the TD off to the British
repair shop - or, if simple enough, do it myself.
