Re: 8 3/4 seal problem / question

[Don Dulmage <big-d@xxxxxxxxxxxx>]

Green bearing do not use the stock seals. green bearings are not some wierd 
specal thing we think they are they are just bearings like we used to find 
in say 55 to 57 chevy difs . Have a lot of friends using them now with no 
seals. have a set in my hemi jeep on a set of strange axles and although I 
have not run them yet they were used for about 9 years by my pal G Wager 
with no trouble.  BTW sometimes it is the splined section that is too long. 
When using the grean bearings which do not require adjustment but are self 
centering you and just lop the extra off the end of theaxle at thesplines 
providng thereis enough spline to still engage. in fact when i get axles 
replined I specifya cetain amount of lengthin the pline so i can final fit 
the axle to suit me. Don
