Unusual! pull the backplate off and have a bo peep....better yet, take a pic and post it

got any oil?

Hope it is not what happened to me years ago. I was driving along a dirt road when the rear locked up. After I came to a stop and got out to see what had happened I discovered that there was smoke coming from the diff housing. Went around to the back to get a closer look and found a hole through the rear cover. Took the cover off and found (apart from no oil) that the CW bolts had all come loose and one of them had sheared when it came out far enough to contact the diff housing and had gone trought the rear cover like a bullet and let all the oil out. The front pinion bearing had melted and the pinion was welded to the housing. When this happened it took three teeth off the crownwheel and cracked the CW housing and everything was a pretty electric blue colour. When I dismantled and repaired it I found the cw bolts never had any Loctite on them and had slowly came loose. Must have been a Monday morning at the assembly plant. I must be one of the few who have destroyed a Sals (without even trying!)

since every thing else is spinning fine, there will be nothing to see, until I get the axel out.

Yes plenty of oil

Aside from the fact its locked one side axle, which will mean pulling the centre to fix the damage, not that I've broken a diff or 50

Ok the side axel is locked to the housing not to the carrier.

Have drive to the other wheel, so not CW or pinion.

drive to the other wheel, she drives ok but the Speedo and taco are a bit out now.= axel not spinning and holding the spiders which are driving the other wheel a bit faster, the difference being taken up by the center diff.

So if an axel only touches the spider and flange. And i have removed the flange so its not there, spider will be ok because there is drive to the other side.

The next closest points or possible contact points would be the stub or the carrier it’s self. Rule out the carrier because that would give the same as a locked diff, which its not. Stub? Well to lock this tight there would be some evidence, hot oil, bluing etc but there is none of that.

So possible is a broken axel that had bound up on its self in the tube??

Either way I will have to get the axel out before even bothering to pop the diff cover

Put the axle bolts in loose, jack up the wheel and rock it violently side to side. If it bound up forwards it may unlock in reverse.
