Replaced Idler pulley and drums support rollers.
Issue 1: Existing Drum Support Rollers were 17mm. Replacements were 14mm.
Resolved: Confirmed with APP that 14mm is the current roller design and they worked fine.
Issue 2: Back rollers were over-tightened with an impact wrench at the factory.
Resolved: Removed back panel and broke free 17mm nuts with socket and breaker bar. However back panel is thin and warped under effort requiring straightening. An impact wrench would have been better to loosen nuts. Be prepared.
Issue 3: Idler Pulley wheel was stuck
Resolved: Replaced pulley. Watch videos on how to reattach the belt properly.
I rated this repair a 3 on the difficulty due to the need to breaker bar off the back rollers and straighten the panel. If the breaker bar failed, I would have had to purchase an impact wrench to complete the repair. Oddly, the front rollers were already loose.
