Just an update. Been mudding in this thing every weekend since the first post and have yet to have a only 1 issue, but its due to mud/sand and thats the parking brake push knob getting jammed. No overheating, no issues with bushings, no issues with wheel bearings. Brake pads are shot, but that is again due to the nature of the driving i do. i love the amazement from others when they only hear its a 500 and I am pulling them out of mudholes with their rigs way more expensive and many more equipped. Yes, i have been stuck but only due to roots in certain holes and high centering, but NEVER due to deep mud. In Low it just putters through and has never bogged down or stalled. Even water above the steering wheel doesnt stop it. (yes, i have sealed everything, relocated fuel tank breather and dielectric grease all connections). I have smacked it against trees and bounced all around, the chassis and cage are all still very tight and dont creak or make weird noises and nothing has come loose.
This is one of the best purchases when it comes to fun/dollar. I will be working on the air susp this fall as i didnt want to tear it down and not be able to ride, and will start another thread.
