Drum Bearing
At the rear of the dryer is a support component called a drum bearing. It helps to hold the drum in position while it rotates. The bearing is covered in high-temperature grease that allows it to move easily. The grease can dry over time from heat that comes off the motor. When this happens, friction is created when the drum turns, sometimes causing an irritating squeaking noise. Locate the bearing by removing the dryer’s back panel. Place one or two drops of lubricant directly on the bearing to quiet the dryer.
Belt
The belt that straps around the Axxis’s drum can make a squeaking noise if it starts to slip or wear. Remove the dryer’s top cover panel that should slide off after you unscrew several screws beneath the control console. Inspect the belt for signs of wear, such as cracking or lifted fibers. Replace the belt if it appears damaged.
Idler Pulley
The idler pulley allows a belt to maintain a firm grip on the drum on most dryers, including those made by Bosch. The pulley has a wheel that turns a section to keep the belt taut. The wheel should turn with ease when it’s working properly. However, if it starts to breakdown, the wheel will stiffen and might start to squeak. The idler pulley is located near the bottom of your dryer near the motor. You can usually access it by removing the dryer’s lower front panel. Evaluate the wheel’s movement by manually spinning it with your hand. If it squeaks or is hard to turn, replace it.
Glides
A pair of plastic glides cover the drum’s metal rims of Bosch dryer to keep the circulating drum from scraping the cabinet. When a glide starts to wear, it will usually break apart, exposing a portion of the drum’s metal edge. The exposed edge could rub on the cabinet when the drum tumbles and make a squeaking noise. Inspect each pair of glides. There will be a pair on the front and back exterior of the drum. If the glides appear brittle or split, swap out both pairs.
