How to Troubleshoot & Replace Whirlpool AP6007368 / WP233520 Thrust Washer

Ended up being a worn drum roller; was missing a washer. Since I had the dryer taken apart ended up replacing the idle pulley, other drum roller, and belt. Figured I can give the dryer a tuneup, so I won't have to worry for at least another 5-7 years. Only cost $80 and a couple hours of elbow grease. AppliancePartsPros had all the parts I needed at the best price. Their model filter identifies all common wear&tear parts, was easy to navigate and order. Also had YouTube install/replacement videos. Now it's is very quiet and runs like new! One stop shop for DIY maintenance. Love it! 

Replaced roller, axle, & washer. Reused Snap ring, but ordered it just in case. Probably only needed the roller, but replaced axle and washer to ensure I didn't have to do it again. 

I found one of the drum wheels broke of not allowing the drum to spin. Took about 15 minutes to replace the wheel and washers and it's back up and running. 

After ordering these parts and another order for the idler wheel, I removed the motor/pump assembly from the washer (four bolts, two hose clamps, and motor electrical plug). Removed the idler tension spring. Inverted the assembly and removed the retaining clip and broken idler wheel from the tension arm (a pair of snap-ring pliers is helpful but not absolutely necessary). Replaced the spacer washers, idler wheel and retaining clip. Reinstalled the motor assembly and reattached the belt to the drum pulley. Reconnected the hoses and electric clip. Attached the idler tension spring to tension the belt. Test run washer. Works great.
