service @60000 mi lists state that rear whl brgs are serviced what's that mean?

What is your question?

I have checked your,and other sources and all agree that at a 60000 mile service a lube/inspect is required for rear wheel bearings on my 2000 Tacoma ---questions I have are:dosen't the gear oil in the differential do the lubing of the rear wheel/axel bearings? ---does this service involve removal and eventual replacement of the brakes,back plate, abs speed sensor, axels, gaskets and seals?---is this servicing part of normal 60000 mile service?---Or is it billed extra even though it is listed on service requirements?----thx--- boatman---
