Needle bearing

Is there any easy way to check that little needle bearing the stub shaft rides on short of pulling the whole hub assembly. I think one of them is bad, as I'm hearing what sounds like the front end turning when I turn left, and a random clunk...that I can not track down. Driving me insane

I've already done one hub on this truck, pulling it off isn't a huge deal, but if I could avoid it, I will.

Other than the bearing, what will I need if I do have to replace it. If memory serves me correct, I'll also need that yellow o-ring seal that goes around the unit bearing?

The easy test is to simply lock the ft hubs IN. If the noise goes away, because Locked those needles aren't turning, then unlock them one at a time to see which side has the noise in it.

I'll give that a try. I'm guessing it's the right side, as the left is relatively new.

you will only need a new o-ring if you are still running the vacuum locks.
