I was ready to do this yesterday. Did some research at brickboard and figured I had all the info and tools and the replacement seal to get it done. I never expected the label on the differential housing would be missing! I removed what little undercoating was there just in case it was a small label, most undercoating is long gone to rust. There is no label to read. Help! Is there any other way to determine if my car has a compression sleeve or not? From what I have read there is a big torque difference on the nut when putting this back together again. I have read that if my car has the compression sleeve it needs 49 ft-lbs on the nut. If it is the no sleeve type it needs 148 ft-lbs. I am at a loss on how to proceed. Thanks for all replies. p.s. Is a new nut just a "be safe" thing, or a strongly advised item to do? I sure do want to have a failure because of a nut.
