S15 4x4 wheel bearings

[jmczzz]

I am putting new rotors, pads, rear brake shoes & springs on my 91 S15 4x4 Jimmy.

 

Manual says, " check wheel bearings for leaks". There are no viable leaks, no looseness, or noise from rear or front bearings.

 

I don't want to tear down and replace if no indication of trouble. The axle diffs have been serviced regularly, no leaks.

 

 

What else would indicate bearings need attention?

 

Thanks, Jim

Looking at all bearing races and roller bearings for pitting, abrasions / burning or flat spots would be another issue. Looking for any seepage from seals. Knowing how to
"preload" the bearing when reassembling would be a few things to consider.
