As above, noticed quite a lot of play in flange to prop shaft, I assume there is a bearing at that point in th diff which I suppose is kaput, is it a case of releasing the drive shafts to release the drive pinion, or is there an easier way, it’s a Rover diff, thanks, Pete
 
By play do you mean in the rotating way, some movement will be had. Or if you grab the shaft and push you get movement up, down and side to side?
 
Could be the nut on the pinion is slack remove propshaft and check the nut on diff. Diff has two tapered bearings if the nuts loose they will not be preloaded.
 
Ok changed diff and fitted a new pinion oil seal but when I tightened the castleated nut it locked up, I contacted d l s and they told me there are two types of oil seal, so they sent me the other one which seemed a bit more robust than the Brit part one, but still locks up when tightened, according to manual is 85 , if I loosen off it frees, any idea,s.

Thanks for that mate, doesn’t,t really help,the diff was a good spare I had, only thing I did was put a new oil seal in and now it locks up when I tighten the castle nut,

take flange off and look down in to the diff is there a spacer or just the taper bearing
 
I have looked down and it looks like a bearing I can read sk on the front, but think I have cracked it, when looking down when flange is in place it’s not quite down flush with end of pinion shaft, I got a spring washer about 2 mill thick that sits in the orifice, and managed to tighten the castle nut up, and seems ok no play anywhere, I will give it a run tomorrow,
