Ordered wheel/belt kit. Found one wheel had come loose as the back retainer was broke. Taking apart the dryer was fairly easy... the difficulty was the power connectors would not come apart. Replaced all the wheels, the idler wheel and belt. Dryer really needed a cleaning inside... was glad I took it apart and gave a thorough vacuuming/wipe down. Getting the belt on was a bit difficult with the clearances you have but managed. All put back together and working...solved the problem and much quieter now.
