1969 B Body I have a axle seal leaking on a Dane rear end. I'm going to replace both seals and bearing on both sides. NAPA shows different seal and bearing P/N for different gear ratio's.. Do I need to know my ratio, or all the axle seals and bearing for a Dana pretty much the same? Thanks for any info..

Dana axle bearings and seals are the same as the 8 3/4". Gear ratio is irrelevant.


I'm supposed to respect my elders, but its getting harder and harder for me to find one now.

It gets confusing with some parts lists, just be sure to only tell them 3.54 or 4.10, those are dana ratios. Dana and 8-3/4, 3.55, 3.91, 4.11 use a different inner seal. I would suggest an E-mail or call to Cass at Doctor diff and get the right stuff the first time.

Inner seals are not the same bearings and outer seals are. Stock dana passenger car seals are 2.5002 in diameter, 8-3/4 are 2.69 diameter..stock housing.
