Sooo I need some expertise on this.
My driveshaft splines look fine but this ...is it a grease seal... plinked off the u joint when I was cleaning it up after removal.
There's a shop in Green Bay WI called Machine Services that specializes in Ujoints and from their shop guy Mitch I was told that for $130 they would install a new u joint on my drive shaft. Apparently, these units are not serviceable.
What advice can you all offer? I think I need to remove these items from the for sale listing and perhaps shelve these for a rainy day. If these little rings are grease seals or dust seals my joint would fail prematurely if sold to an unsuspecting bricker...
