Hey guys I have a 1989 big bear that is in near mint condition, with one problem.. when I roll it in backwards with the gearbox in netruel it rolls good for 10 feet then the rear of the quad starts to squat and is really hard to push. My first thought was the brakes so I completely removed the front brake shoes and rear brake pads and still have the problem. Has anyone experienced this or have any advice?? Thanks

 

Next thing I am going to inspect is the transfer case ujoint. If any one has a 1989 ish big bear 350 can you please do me a favor and go roll it in netruel forward and backwards 15 feet and see if you experience any resistance or suspension squatting.
Thanks

 

I don't know if I can help you here....probably not.. But I can't see any logical reason that any ATV would experience what you are unless the ATV has an axle/bearing issue. You say you have removed the front AND the rear brakes....right?

 

Yes brakes are disconnected also something I forgot to mention is when I lift the the quad in air and spin the wheels there is no resistance at all and ever thing is smoth. But I will inspect the bearings thanks.

 

I have a 94 big bear pushed it forward and backwards and no squatting , however if its running and I put it in reverse it does squat a little bit

 

Thanks RJ for taking the time to help me... I am pretty sure that I have the problem narrowed down to the front drive shaft u joints.. I will be sure to post my results after I install new ones.. thanks

 

no problem , hope you get the issue resolved

 

Anybody have a ujoint part# for a front drive shaft for a 89 Big Bear that I can get from napa of some other auto parts store or am I stuck buy from dealer? Thanks

 

not sure of a part# to buy at napa, but there is always ebay or online shopping
