how much dose it cost and is it hard to replace

[mhunt]

i just replaced mine last week. You can get bearings and seal kits that run anywhere from $10 (ebay, cheap bearings) or around $45 (pivotworks) it's not hard at all but if you're not mechanically inclined, you might need a manual to walk you through.

do u know what would cause it to go bad im kinda new at sport atvs

[mhunt]

a number of things could cause a bearing to go bad, mainly water/debris in the bearing. the water washes the grease away and debris, like dirt, ruins them as well.
