I guess I'm just an old fart. *sigh*

But then, maybe that's why they lasted 165,000 miles on my 1992 without so much as a repack. Those look like non-tapered rollers in there, in the O-Reilly pic. Is that so?

Lot more load-bearing area. And no adjustment? (No opportunity for mis-adjustment, either.)

 

non tapered, I think what you are seeing is the grooves for the splined axle shaft that goes in there. I'm not sure what kind of bearings are actually inside it.

 

They are sure it's the bearing right? I have fairly aggressive AT tires and as they wore they were sounding exactly like a bad wheel bearing to the point that after I couldn't find anything wrong I took it to a local mechanic I trust for a second opinion. He checked it out and said the bearing was fine but the noise was caused by the tires, even he agreed it sounded amazingly close to a bad wheel bearing.

 

I believe its a wheel bearing. I still have the factory tires on so I dont think it would be that and I actually bring my truck to the local performance shop for everything so I trust them. My friend works at a garage so he told me just to order the part and he will help me change it out for nothing but maybe lunch and a 6 pack. Also you guys are right it comes as a hub assembly and the cheapest I can find around here for the premium part is $155.

 

Both front wheel bearings under 5000 miles (yah, that's right... 5000).
