RV: 1994 Fleetwood Bounder
Engine: 190HP, 5.9L, 6BT5.9
Tranni: Allison 4 speed
135,000 miles
Description of symptoms: Began hearing a strange noise from the rear of the coach that got louder then the radio. Pulled over at a rest stop and put my hand on each hubcap. Found a hot one on the drivers side rear of the coach. Also smelled something strange near that wheel. Allowed wheel to cool then slowly (under 45MPH) drove 20 miles to where I could deal with the problem, made a few calls and got into a shop near my home town.
Problem: The left rear bearing failed, probably caused by hitting a speed bump in Mexico the month before at 55MPH. The spindle had cracked and a leak of differential oil had ruined the brake pad.
Solution: The bad spindle had to be sawed off, a new one machined and then welded in place and further machined with a neat milling machine that hangs right on the axle & spindle assembly ($1300 just for that job). Replaced bearings on both sides (rear). Replaced brake pads both sides (rear).
Cost: $2500
