Big bear 4 wheel drive

hey guys,

I just got this Big Bear 400 4 wheel drive. Today I was pulling a heavy ice shanty. When starting out on the ice I noticed the right front tire wasnt spinning.

Is this normal? One guy that was with me thought it may be a limited slip rather than true 4 wheel.

any thoughts?

thanks... Kane

Yea the BB doesn't have a locker. Highlifter does sell locker kits for them though.

yes kanes, It has an unlimited slip differential(thats pretty much how it works like) So the tire without the traction will spin, The one that actually could pull you forward won't thanks to bad design.

Next time you find yourself stuck (wheather in mud/snow/etc...), and only 1 of your front tires is spinning and the other is just sitting there....Apply the front brake a little at a time and it will "lock" the front end. At least it does on my Foreman. I would try that a few times before I wasted my money on a locker IMO

Ya that just your forman. It has a more advanced differential than the bear. I don't think it will work on it

That's a little trick that works on all 4x4's without a locker.

The only advantage to having a 3 wheel drive set up is you are a lot less likely to snap an axle shaft.

I also said try it.

...And unless something is wrong with it, the axleshaft will not break with the power output of the Big Bear....

It's not just about engine power output. Tire size and weight play a big role. Also the year of the BB. Yamaha used a different axle shaft for all their '03 4x4 Utilities that are more prone to break.
