Product review (4 stars): Replace both rollers, both axles, and c-rings at the same time.
Worked great. Purchasers should seek out at least two videos before doing the replacement job. On many driers, there is a spacer bushing behind the left rear roller, but not behind the right roller. And I damaged one roller while installing the drum. I had to buy another pair, and replace the damaged one. I'm not complaining: It's the difference between a pro and an amateur. There is a trick to lifting the rear of the drum so that it is a gravity-captured connection to the two rollers.
