May have found my bus...but it has a rear end vibration

01mark and others, you might be interested in this report by Timken bearing mfg--see page 19 regarding brinelling. Here is an interesting quote: " Improper mounting and disassembly methods and/or extremely high operational impact
or static loads may cause brinelling."

Seems bearings can flat spot just sitting---- Jack

yes I am reasonably sure Chrysler knew what they were talking about when they told us to change out hundreds of bearings because they had flat spots on the rollers. Gene

Well than the engineer is a little bit reasonable.
Races and ball or rollers will flat spot if vibration or enough compression force is applied to pass through the elasticity cycle of the metal.
There is a term people don’t associate with metal. Elasticity
