Working on my POS '85 X1/9.

The front wheel bearing was way freaking shot. I'm embarrassed.

There is a steel retaining washer underneath the spindle nut. had some rubber remnants around it, like it was may have once been a secondary seal for the wheel bearing?

Picture 1 is the new bearing in place, with the old nut and the rubber washer bit in question.

Picture 2 is the washer bit close-up, so you can see how the rubber is cracked and perhaps torn?

Again, this is the later type front spindle. No retaining nut requiring the special tool - just a circlip and what you see pictured.

Would that have been part #4374303 listed as a "gasket"? Showing one on each side of the bearing?

yes, definitely rubber. And it's definitly bonded / vulcanized to the steel washer-like core.....

If it doesn't pop up to page 7, scroll down to it.  There are supposed to be "gaskets" on either side of the bearing, items, 5 and 7 in the expoded drawing.

(BTW... this stuff is found EASILY in the Best Of section under Online Manual... that Damon so thoughtfully uploaded and posted for us.)

Again, this is the later type front spindle. No retaining nut requiring the special tool - just a circlip and what you see pictured.



There are three purposes for the washer seal.

First, to protect the bearing seal from impact damage. Rocks, stones, grit and other nasty stuff very often gets wedged up in there and tries to grind away at the bearing seal. Better when that doesn't happen, hence the added layer of protection.

Second, the washer seal keeps contaminants (mostly worried about water) away from the knuckle-to-bearing surface. That way, the bearing doesn't get rusted into place and the knuckle surface doesn't get ruined so you don't have to throw it away along with the bearing.

Third, it backs up the bearing seal to help keep contaminants out of the bearing. Here, we are working on the experience that many of these double row ball bearings specified by Fiat (from various vendors) have an unfortunate history that they are not equipped with the greatest seals. Or the seal material itself is questionable, or the assembly is less than perfect. Let's just say elastomer engineering and quality control has been an issue with many of the bearings sourced in Italy.

We're talking here primarily about the inboard side, because the outboard side of the bearing is protected a bit more by the rotor hat.

thanks for the refernce to the pics. Didn't think to look there. Actually what I was llokign at was #4, the "washer". There are also remants of #7, the "gaskets" -- I had thought those were what was left of the bearing seals.....

This stuff is going to be unobtanium, isn't it?
