Default Unit bearing D60 question

simple question... what supports the axle shaft on a unit bearing axle?

On a kingpin, there are needle bearings on the inside of the spindle....

here is the deal. I have a "squel" on the right front of the D50 in the tow rig. I think it happens when the axle shaft (that isn't turning) rubs part of the unit bearing (that is turning). When I lock the hub in (so the shaft is turning witht he hub), the noise goes away. I thought it was the hub, so I swapped the left and right hubs, and the noise stays with the right side.

Is there a bearing between the unit bearing and the shaft? If so, is it servicable or is it an assembly to the unit bearing. Or is there a bearing that sit in the axle tube toward the C?

sorry this is a newbie Q... I've never had a unit bearing axle apart.

Your unit bearing is bad you have to replace it

The unit bearing supports the axle

x2 They will rust up, they sometimes take out the stub shaft as well, you can buy that bearing separate.

I fully understand teh Unit bearing supposrts the weight of the vehicle via the hub, but that isn't the problem. I was asking what supported the stub shaft as it was passing throught the ID of the hub.
