I've had mine since 1998 and only put 1 bearing in the rear axel tube. My dads honda 400 has went through 12 bearings and 2 hubs and it's the same model. Does everyone share my luck because I drive mine hard!

 

I have replaced the right rear wheel bearing once. Thats it for wheel bearings.
My CAT is also a 98 454 4x4. We have had great luck with it. And it has been rode hard
and has held up good.

 

My 98 500 Cat went 3700 miles with the original wheel bearings, ball joints and tie rod ends. All this with 27" Vampires and mudded every time out. However the 01 250 has had every wheel bearing replaced on it, and the 02 500 I had went through one front bearing in the 900 miles I had it. They all use the same bearings but it seems like the older ones may have held up better. At least mine did.

 

Yes I,ve had great service with my ac. My only problem currently is that I keep fouling plugs every month or so. I need to take the carb off and clean it. I just wish we could find more accessories for our models.

 

At 2500 miles I have change all wheel bearings once, but I'not afraid of mud.
