Jeep has started making a new noise..... only way to describe it, is it sounds like a whining when on the gas.... checked all the obvious things am about to check diff fluid and change.
Now this is my question, when I jacked the rear up and checked I had about an inch where I can turn one rear wheel before the other moves (have recently had fitted 4.56 gears and a truetrac) is this normal with this setup???? or is normal anyway??? please say yes!
Don't know what vehicle you have, but I just changed back axles on my 81 CJ, still up on stands, had dif cover off, still looks like new in there, no locker, anyway I can turn one wheel a 1/4 turn before the other does, don't know if this helps you or not.
Some play is normal and is designed in when the gears are setup. Not sure how much or how it's measured though.

Bill, you should know by now that a Truetrac is a limited slip differential, not a locker.
And Simon, the whine sounds like the R&P installer may have not set them up properly.

and the
differential,
I'm with Jerry on this one. The slop you are experiencing is not abnormal in itself, but coupled with the noise, it sounds like the R&P set-up is wrong.
well dropped the fluid out and I think I've managed to get some water in there, just milky grey goop came out..... oops
teeth look OK and can't see an obvious signs of damage, so am hoping it's just a bearing.
Cheers for the help and advice tho...

Hope it's just water you mean....
You might have no damage yet, just some wear.
I would fill it and drive it to see before ripping anything apart.
The inch of rotation is normal.

Thanks guys, what diff oil would you recommend??? One mechanic I've spoken to has suggested 75/140??? never used that before myself, but this is the first time I've changed the fluid since putting the truetrac's in.
Cheers Sim> Hope it's just water you mean....
When I dropped the rear prop out there was about 1/8" of slop on the pinion, didn't seem right to me! Also correct me if I wrong but water ingress would cause that would?
Took all apart and replaced the all the bearings, not too difficult.... but then I had a mate who helped. Everything is back together again it sounds
1000 times better, there is still a very slight whine (you can only just here it if you listen for it) but this gets overtaken by tire noise when you get above 40mph.....couldn't afford to take it back to the shop, they said it was because of the water damage and wanted £400 to take a look and replace the bearings plus it's 200 miles away.
The whine is dangerous!
Just had a pro do my rear bearings and it is so quite it is scary.
