Both passenger and driver were toast. The inner ball bearing retainers on both sides were broken or cracked.One race had a scuff on it.The key on the washer under the castle nut was torn off on both sides. I replaced the king pins and all of the bearings 5 years ago. I have only put 7000 miles on the truck.Any ideas why they would fail? I would appreciate any feed back before I invest in new parts again.Thanks. | | | | | Joined: Dec 2004 Posts: 1,897 Shop Shark | | Shop Shark Joined: Dec 2004 Posts: 1,897 | Roller or ball bearings? Where were the bearings made?
Wheel bearings should last 50k miles or more, however the new steel they are making them out of is crap. Make sure you get a quality set of bearings. | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | not properly installed - too tight likely, maybe too loose, and maybe never checked after redone?

I also had trouble with old stripped castle nuts which I replaced.The bearings are (were) ball bearings and although made in China they were supposed to be a top brand.I will check my manual and see if there is any reference to tightness if I can't find the right answer I will get back to the forum.
Thanks again for the opinions.

After recieving them, I popped them open and saw the large made in CHINA stamped in them. They were sloppy in the race, which no ball bearing should have any 'feel' of movement in. I sent them back and reordered through my bearing supplier. I recieved some Japanese bearings of a much higher quality. Its been several years with no problems.
I believe they need to be torqued at 35 foot pounds, not like tapered bearing settings, but my memory may not be serving me correctly...
