No drive to the nearside rear?

Hello again. Those of you who have read any of my other threads will by now have realised I have bought a real crock! Anyway, having not played with my 02 Jimny for a couple of weeks after fitting proper rear 2" lift springs, I went for a drive, got about 20 metres before turning around due to a really odd noise from the rear. I jacked up the rear and didn't really seem to be able to replicate the noise, but eventually took both wheels off and then whilst on axle stands, got my wife to sit in and go through the gears. No obvious noise, but now I could see the rear properly, I noticed the rear offside was not rotating at all. Unlike the offside which was turning as expected. Am I missing something in how these diffs work, or does it point towards yet something else I need to address in terms of the half shaft or diff itself. Thanks

Brakes are fine as I suspected them first so took the drums off. I will investigate further with the light tomorrow and report back. Thanks. There are no obvious clunks or bangs, so maybe all is well. 

Fingers crossed then!

The drag could be caused by a wheel bearing that is breaking up. The half shafts should rotate smoothly and quietly with no up or down movement but with a modicum of in and out.
