i have a 2003 polaris sp 400 and for some reason the right rear axle keeps wearing th e fastest.when i bought it the guy said he had t oreplace alot of boots on the right rear and now i have replaced the the half shaft once back in august 2009 and now its clicking again. only when your in reverse and turn right.is there anything that im doing wrong.just like last august.the other prblem for my machine is the winch.when i tryed to to pull a quad out( not over 1000lbs of tention) my winch started to pull and the grinded. we flipped the freee wheel *** back and forth and push it in to the bottom. it grinded again but with bearly any tention it goes in adn out normally. is this the gear inside of the housing.

my dad has a 2004 polaris sp 600 and he has a polaris winch also. but his willl go out but when u push the in button it does nothing. is this the rocker switch or the little box at the back of the bike that has i think is the relay.

if anyone no's anyting please help. please tell what atv your talking about.

 

well I would say your winch in shot, unless you want to buy and change out the gears. and your dad's most likely is the contactor, you can buy a replacement for about $40 or $50 I believe on ebay, also you could buy a warn contactor to replace the cheap polaris one

 

I would look and see if the rear arm is bent in any direction causing more bind on the shaft or messing up the suspension travel. Could be bent up,down, forward or backwards. Also check all the rear bushings to make sure the rear suspension isn't moving around more then it should.

If you are tearing up the cv boots I would get better boot guards.

 

check the bearings on the 400 and make sure you're torqueing the nut down properly.
On the winch problem ,sometimes all they need is a disassemble ,good cleaning and relubed

 

the cv booot looks fine but i didnt take a huge look at it.last time we changed just the half shaft so could it be the inner cv joint and if it was would i have to buya full shaft or do they make a innner half shaft

 

I would order a whole new complete shaft from the cv-man he is half the price as the dealer an it is noticably a much stronger shaft and when i ordered it he had it out the door the same day, do a search online he is a real good guy to deal with
