I need to replace the rear bearings in my Raptor. I have read many how to's on the subject but I still can't decide how much grease to pack in the carrier. The carrier now does not have any grease in it but the how on another web site says to pack it full. Wouldn't that cause a lot of drag at high speed? What's best: packing the grease outside the spacer, between the carrier and spacer and then on the axle as well; or just do as they do stock, no or little grease in carrier? I know the answer sounds obvious-grease is good but think about it at 70mph with the grease around the carrier spinning like crazy. Tons of drag. Any thoughts? Thanks.

 

I just replaced the bearings in my RAPTOR
and I just put a little grease between
the outer seal and the bearing to help
the seal keep water out the bearings
themself are sealed with grease so
no matter how much grease you put in
the carrier it won't help that much
just be a bitch to clean next time you
replace them

 

From past experince, to make your bearings last longer. You should take a ice pick or simlar tool, and carefully remove the seal that is on the bearing itself. Then pack more grease in the bearing, and then press the seal back on. You will be suprised at the amount ( or lack of) grease that is in new bearings. Also when installing bearings in a housing that has a grease fitting it does little good to the bearing if it is installed with both seals on the new bearing. Too reap the benefits of the grease fitting remove the seal from one side of the bearing, then install the bearing with the remaining seal to the outside. Now when you pump grease into the carrier you force grease into the bearing not just around it.

 

The dealer just replaced my bearings under warranty. The head dude told me that if you wash your Raptor too much that the water works its way into the hub assembly and pollutes the grease. He also said that if the chain is too tight it will put undue stress on the bearings.

 

I recently just bought a new carrier bearing with the bearings pre packed. Was wondering if the spacer between the bearings should be loose inside the housing itself?

 

What one did you get? I just ordered the niche complete assy. Hope it’s a good one. Has a grease fitting but where’s the hole in the carrier???
