2015 rzr 900s already worn out?

Bought in feb, really love the machine but wow I am on a first name basis with the parts dept. So far I have replaced the steering rack all 4 wheel bearings and all the a-arm bushings are very loose I went through one set of ball joints and install the high lift front a-arms, all the rest of the suspension seems very loose and you can wiggle the wheels back and forth with the new rack the steering it is at least tight. I grease suspension befor every ride and change oil every 50 hours and so far no engine leaks or problems, with my modified intake the air filter stays very clean even in harsh conditions. My question is, anybody else have suspension problems, my machine has 2000 miles
