Prove it? Well I bought the truck new, and I have never changed
the wheel bearings, but I have repacked them 2 times since new,
the first time I had about 150,000 on the clock, and then at 250,000
This was a Daily Driver, but I only ran 235s for most of it's life on stock
wheels, it wasn't until I rebuilt the engine and added the turbo at 230,000
miles that I went to the 33s and aftermarket wheels, 8" x 4" backspace
so haven't really stressed the bearings for that long I guess, only about 50K
miles.
