Differential Oil Seal Replacement

[WIL35]

The input oil seal on my BTR diff is leaking; does anyone know, typically, how tight the nut is that I will need to undo on the diff input, to get to the oil seal?

I'm trying to work out if I can get it undone with a heavy duty socket set with extensions or whether I would need to hire a compressed air driven impact wrench.

Thanks

If you have access to a lift you should be able to do it with a breaker bar and a length of cheater pipe, if however you won't be able to get it very high off the ground I would recommend an impact wrench, assuming you are doing this "in-car". The pinion nut is usually torqued to above 250 ft/lbs and has copious amounts of thread locker applied.

Thanks, that sounds promising. I can get the car 2ft off the ground on some full length ramps. I've got a 3/4" drive socket wrench with a 20" handle on it and a short length of scaffold tube for extra leverage.

Presumably I'll have to stop the wheels trying to turn at the same time!!

Biggest problem I had was finding a socket to fit, in fact so far I haven’t.

Isn't it a standard metric size then?

Don’t think so. I measured across the flats went off to the local second had tool emporium and came away with what appeared to be just the job but not so, have been back several times to swap it for a different size. No luck in finding an exact fit so far.
