It's possible. The H2 rims don't have a significantly different offset from stock. My feeling is the offset has more impact than the tire size (within reason). I've been reading where some folks with stock trucks have had issues, but some don't. Who knows. It's probably luck of the draw as to whether one's truck is trouble free or a problem child. The only other issue I have is the steering box leaks. Not much just keeps the box damp.
Autozone didn't have the ball joints or a clamp for rent. I may spring for my own clamp. I found on the web a set of 4 joints for $220, which I think is pretty good. They won't be greasable, but for that price I'll just plan on another 58k then replacement.
Also from what I understand, neither my steering box or joints would be covered under the 7/70 warranty. Neither are powertrain items.
