Diff play

Had my SIIa up on the ramps this weekend to check a few things over - including figuring out where all the oil levels are and checking those.

I knew that the front propshaft (rear) UJ had play in it - when I bought the truck in January the seller gave me the advisory not with the MOT from August 2008.

It said 'slight play' on the advisory note - but in the intervening 6 months this thing has become wobblier than a jelly on a trampoline - I think I was very fortunate it hadn't given and taken a chunk out of the gearbox in the process.

Whilst checking I spotted a small amount of play in the rear prop UJ - looks like a bearing race (is that the right name lol) had broke as I could see the bearings - so that's both props off and UJ's ordered.

Which brings me (finally) to my question - I have some play in the rear diff. Is this normal that i can rotate it a wee bit? It's a rangie diff if that makes any difference...

if you hold the flange on the diffand turn from left to right how much free play is there

Not much really, I can rock it a few mm to either side. Probably worrying when it's not warranted, having seen how what is described as 'slight play' in the propshaft can rather quickly turn into a 'how the **** is it still in one piece' situation!

a few mm iether is about right if it was a couple of inches thet would be a disaster, as for the uj any free play on them is telling you to change them quick,even a tiny ammout of slack will give you vibrations and alsorts of problems it could even wipe out your g/box, i would get them changed asap,

Ta, glad the diff isn't a problem. UJ's on order from Paddocks.
