bj8 wheel bearing discrepancy

i just received my order of wheel bearing components and guess what? they don't fit!! the grease seal,for example, is about 1/4" larger diameter than the original. am i the first to have this problem? can someone tell me what is going on?
 
Somebody screwed up; the only difference between a BJ8 front hub and the prior (6-cylinder) hubs is the use of a smaller diameter outer bearing; the hub seal and inner bearings are the same.

I've had a little exposure to hub dimensions when producing these...

Well Steve, I do not think you are the first to experiece this phenomena nor will you be the last.However, I do find your situation to be absolutely abstruse and will require considerable ruminating to locate it's cause. Consequently, the wheel will not be going on!.--Keoke- /ubbthreads/images/graemlins/laugh.gif
 
well guys, the mystery is solved. i did it the hard way; that is, i ordered the correct grease seals from another mail order house. sure enough, the new seal was too big to be pressed into the recess in the RH hub. being the clever cat that i am, i then tried, for the first time, to fit the seal in the LH hub. guess what, it fit!! now, out comes the micrometer. the recess diameter in the LH hub mikes out at2.87 inches which closely matches the n ewe seal diameter of 2.855 inches. the RH hub recess measures 2.446 inches. MAGAWD, someone has slipped a mongrel hub into the old girl. needless to say, a new hub is on order. i guess this experience goes to demonstrate the need to take our cherished vehicles apart before we can rely on their roadworthiness. thanks to those who lent sugestions
 
Well that did take a bit of ruminating /ubbthreads/images/graemlins/thumbsup.gif----Keoke--- /ubbthreads/images/graemlins/grin.gif
 
When I got my car I had a BJ8 on one side and a early 3000 on the orher. Calipers did not fit and I had to get the entire spindle on out.
 
Steve, I have a concern that you may also have the wrong spindle axel at the problem location on the car?.---Keoke
 
the spindle mikes out the same for both left and right, but i got another unpleasant surprise today when ups delivered the new spindle i ordered last week. the outer race for the innner bearing is more than a press fit, it's a sledgehammer fit! the outer race for the outer bearing rattles around in the hub recess that i also expected to be a press fit. i called the mailorder house that supplied the hub ands the corresponding bearing kits and they have agreed to pull a hub and a bearing kit from stock and see if their parts fit together as they should. if they cAN PRODUCE A MATCH, they will send the matching parts to me.
if they can't come up with a fit, i think i heard some mumbling about shooting themselves.
 
randy,nice, and ya did it with an exacto knife and a bit of sandpaper? wow! see keoke i aint da only one! /ubbthreads/images/graemlins/devilgrin.gif

What really bothers me is the fact that the smaller seal fit on the one side, but the proper seal which was too big for the hub was mismatched. At the base of the Axel ,Inboard side is a round disk like distance piece if the smaller seal fit that distance piece the larger one would not seal on it even if it had fit the hub. Sumpin wrong there someplace.---Keoke
 
you seem to be assuming that the seal with the larger outside diameter has a larger inside diameter. the inside diameters of both seals are almost identical. with that great truth established does anyone have an idea of the origin of the "mongrel" hub? maybe, as a last resort, i can find a seal that fits the mongrel and reuse it.
 
Ain't never heard of such. However, perhaps the seal that fits the Mongrel has some Identification on it; names and numbers if so it possibly can be traced on line or through a high quality bearing supply outfit. Most bearing supply houses can simply match it up using its dimensions if you take it in. seals like bearings are pretty much standard. -Keoke ?
