I've only seen excessive thrust bearing wear once on an employers 1991 F150 4x4 plow truck that was still under the factory warranty.
According to the dealership the cause was a faulty torque converter that was shoving the crank forward. I got a look at the actual mess it caused because I was friends with one of the Ford Dealerships' mechanics. They installed a warranty replacement 302, AOD transmission, and torque converter and the problem went away permanently... fairly extreme remedy but effective.

It could easily be the transmission and apparently it's difficult to track down. This article may be a good jumping off point...
