How to change axel bearings on 400ex.
The hardest part is getting the old bearings out. There is no lip to catch a punch on. You can not push them straight threw. If you try that you will break the carrier. I have welded a piece of steel to the bearing race to have something to hit on. Weld a scrap to one bearing, knock it out, slide the tube out and then you can remove the second bearing.
I have 3 quads and atleast 2 are broken.
