Re: 8 3/4 seal problem / question

[Wakeman Massie <wakey@xxxxxxxxxxx>]

Thank you, excellent info.  I always used Green bearings with stock seals in 
the past with no issues, but I never tried on a pre-'65 housing.  I've had a 
few different axles (Jeeps) leak at the seal which makes a mess of the 
wheel, tire, wheelhouse, brake drums and shoes, so more sealing is better 
IMO.

But I took your advice and I yanked the seals this AM..  I agree it should 
be OK with the Green bearing.  Voila, the rearend is now done.

Thanks again

Wakeman
