All My Rear Bearings Get Toasted

[moogenite]

Mugen and Associated have the 15x21x4 bearings on the inside.

outside is same as most other cars, but i've heard many mugen driver say the inside bearing fails often.

I dont see why you'd have issue's with the outside wheel bearing failing other then bad balanced wheels, extremely rough conditions or immense dust.

or you have bent your axles... so they put stress on the bearing... did you check?
