Rear brake backing plates

I dont think there is either, now that you mention it. I've all ready got a whole new bearing kit waiting.

 

That would be the magic bearing tool alright.
Such a well thought out design... It made the job almost painless (almost because while i was doing it, i tripped over the hydraulic lift base that was holding my truck up in the air, and cracked a couple ribs... But even with broken ribs i was able to finish the job that day with the tool )

 

If you do it, i recommend replacing: backing plates, wheel cylinders (theyre only $10 and it beats the hell out of fighting to get the old one off a rusted backing plate or trying to open a rusted bleeder screw), plan on getting new studs and nuts for the bearing housing if the rust is severe (2 of the 4 on each side broke when taking mine off)... Of course axle bearings, inner and outer seals, and axle bearing housing o-rings....Since you have the brakes all apart, might as well do those too...So new brake shoes and brake hardware kit...and last... Depending on rust... Plan on replacing the 2 brake hard lines to each wheel... They'll likely break too... And new parking brake cable.
