you need a new bearing carrier, wats the black bar coming off the shouck mount?

[hondaking52]

and is your swinger cracked to?

yea looks like you do need a whole new bearing carrier. My friends 400ex had the same thing happen where one of em broke off and he had to pay alot to fix it. His bearings were out and it ate the shiz out of the carrier which i guess also tweaked the outside at some point. I think he had to get a new axle even or maybe swinger. cant remember. I just know you should check your bearing every once in a while.
You may of just cracked it on a rock or something though. idk

its a support for the tow bar. and no its not cracked. thats a leaf stem from the ride last nite

looks like this when you pull it out.

Just buy an aftermarket bearing carrier. They come with dual row bearings that last so much longer and have grease zerks on the sides so you can grease it without removing it. My favorite brand is rad
