I have a ford 8.8 with LSD and 4.10 disc brakes, how can I tell what it came out of so I can get the correct seals and bearings. I also need to get the correct calipers and pads. Thanks.

You fixing these up for me? lol

I'm glad I didn't let these go like this I would have been embarrassed, didn't know the 30 was in that kinda shape and the 8,8 needs seals for sure.

Does it have the tags on the diff cover?

I just bought axle seals today. I just picked the year 1999 and went to autozone and asked for seals for an explorer of that year. They gave me the right ones for $4 each. I have a disc brake 31 spline 8.8

Not that I can see

Maybe mine is the same, are all 8.8 31 spline?

Wouldn't have hurt my feelings. I would have gone through them before putting them under the XJ

no.
Ranger and mustang axles are 28.

Is there any markings on them as to tell which it is

Count the splines..

For the 8.8 diffs that would fit a jeep with out narrowing there are only 2 seal options. The 2 are 8660S (aprox 2-1/4" O.D.) & 8835S (aprox 2-9/16" O.D.) National seal numbers.

Hope that helps,

Miles

Are there disc brake 28 spline axles out there? I have never seen one. I will be looking for spare shafts before long and am curious how careful I have to be about what I get.

Thanks for the info it's helpful
