Would like a little advice here. I am currently doing a brake job and replacing the four bearings and inner seals on
the four rear wheels. I have 9 Napa seals 21771 that interferers with a 1/4" dowel pin. I checked with all of the
parts stores in my area and all the seals interfered with the lip. In my bag of spare parts I have an original
seal #3857731 and it also interferes with the lip. The only difference that I see is the original seal's chamfer is
.060" wide where the Napa seal is .090" wide. If I remove .030" from the Napa seal would that give me the sufficient
clearance so the bearing won't rub and contaminate the bearing with metallic fillings from the seal.
I did a pre-test on the rear spindle with the Napa seal and could not see how the bearing could rub on the chamfer,
but the bearing was not under load either.
