New floor boards

So I bought a set of far mudding floor boards.

Fitment isn’t 100% but works.
You can’t use factory xmr foot pegs with them without some modification.
You lose the factory fender flares.


But I don’t have to worry about rubbing now with these 32s.

Maverick whine

I have a whine that only happens in drive but not in reverse. Ive changed the one way bearing, replaced to belt and put in a new clutch kit. The only thing I haven't checked is the rear diff. I changed the fluids in the engine and transmission 3 rides ago. Any help would be appreciated.
