What nobody has yet mentioned is that GREEN is a company name like Kleenex orB.F Goodrich. The "Green bearings" are not roller bearings like a soda can, but BALL bearings. They are absolutely nowhere near as durable as the factory style tapered bearings manufactured by the TIMKEN corporation. They will never last 100,000 miles like the Timkens. They will not last if you enjoy road racing or any type of cornering. They are okay for drag race cars that spent 99% of the time in a straight line.
The only advantage these inferior bearings have over the factory stuff is that they need no adjustment. The adjustment takes a few minutes. You are not gaining anything by switching. I didn't know about the weakness of the ball bearing design until 2 years ago when my "Green" bearings started failing after 7000 miles. I would have installed the Timkens but my axle shafts have been cut too short to utilize the factory setup. I went with Mopar performance bearings that are essentially the same as the "Green" versions. When these fail, I'll order new axle shafts and go with the Timkens again. I like to cut corners rather than drive in a straight line.
There are rear disc brake kits that work with the Timken bearings. Contact Doctor Diff. He sells brake kits at reasonable prices. I have his 10.7" kit on the Charger. It uses Toyota rotors, Mustang calipers and pads and a custom bracket to mount it all.
