Hi all. I have owned my Coleman Fleetwood Nevada GTS for almost 3 years. I have rebuilt it from almost the frame up. I have never messed with or worked on axles before. What I am looking for is to replace everything but the axle beam. I have searched this site and I have the manual, but can't figure out for sure what size and parts I will need. E Trailer website said the most common parts for a 10' or bigger pup was 3500 lb 10 x 2 1/4" wheel assembly. I am not sure I am right. The reason I want to do this is for one I have know idea how old these parts are. Plus my friend towed it for 40 miles without the E brake pin connected. I have not moved it sense. What is the best way to figure out which bearings, brake kit, drums, seals and whatever else I would need? Or problem I may run in to? At the same time I would like to install a over under kit. Any info would be greatly appreciated. FYI I have not removed the wheels yet. Waiting till spring. Thank you for any help.
