So as a follow up,
that set that the service center put in gave up the ghost at 30,000 miles.
I bought the tools from Motion Pro and did the last swap myself. Its 12,000 miles later and there is no sign of that 10,000 mile notch from the previous 3 sets of tapered roller bearings.
The thing I did different was to just tighten the bearings to the factory torque spec. I didn't "crank 'em down to seat the bearings, back it off and then torque to spec" as it was explained to me by the previous folks that did the job to assure me that the bearings were seated well and would last.
