I have a 2006 TH4400 TrailHand. This was SUPER helpful info -- thanks everyone for posting. I can confirm the only way to do this is dropping the engine/tranny subframe. You don't have to remove the trailing arm, brake, e-brake, etc. -- just use a ratchet strap to pull the trailing arm up out of the way enough to remove the cover.
However, now I'm into ANOTHER problem -- the primary clutch is shot, and there's no availability from the dealer (besides it listing at $1250). Anyone know what the equivalent replacement is? I pulled all the numbers -- TEAM makes the primary and secondary set. TEAM won't help, none of their suggested vendors have any idea.....is this basically the same clutch used on the 2006 Polaris Rangers?
