I am having the worst time trying to solve a axle seal problem. I've asked several forums where it is more appropriate since this is in a '67 gto, but I get 4 different answers from 4 "experts" and they are all different. Here's the deal... This axle is in a '67 gto, but probably not the original. There's a chance it's from a '69 GP. My axle seal was leaking. Looked at it and found the retainer plate was bent. Took it off and found that the seal (an inner type) casing was ground up and the bearing was not seated in the housing all the way. It had like 1/2 of side-to-side movement. I****umed the housing was not made for an inner seal and got an axle from Flat-Top that had the machined area for the outer type seal. The axle that was in it slides right in, no problem till the bearing hits the inner seal. The new axle won't mesh with the splines even though they are both 28 spline axles and every measurement I take seems to be very very close if not exactly the same. It acts as if the splines are cut too shallow on the new axle. Anyone ever seen this? Further more I don't know if I have a 8.2 rear or an 8.5 and then I don't know what PN for bearings I need or what seal it should have. Most people agree it's an 8.2, but they seem to use the inner type seal, and I can't get that to fit in the housing I'm losing my patience with this thing. I've spent 3 days on it now just trying to get it back on it's feet again. Here's some pictures of the axle, housing and seal that didn't fit on this site: GTO Headache
Yo Rev...I can decode your axle for ya if you give me the code stamped on the left axle tube, about 3 to 6 inches out from the center section. Some have it stamped on the backside and some have it on the front side...usually on the back side.. It's gonna be a series of letters and numbers.
I take it back Rocky. I found a few more numbers that might mean somthing.OK here they are.. N166 (on axle tube facing down driver's side) 00 or uu kinda bad stamping, but the look too round for Us (above the N166) 67890 (cast into the center section) 128?3(?) (also cast into center section, above the other) If these decode into anything please let me know Thanks in advace. Oh and also I pulled the other sides retainer plate (everything looks original on this side) and it Does use the outer bearing seal.
