How are you checking this with a level..?.. A few years ago the TRX350FE/FM were breaking the "A" arm mounting lugs off the frame and Honda came out with a kit to make the front lugs stronger .. Since then we've had 2 TRX500FA's do the same thing .. If the top "A" arm mounting lugs move just a little it will throw the top of the wheel out far enough that it can be easilly seen from the front of the bike ..
First check the frame around where the "A" arm bolts on for any crack or paint cracked or chipped off that looks like the mounting lugs have moved..
