Whirlpool dryer WED4800XQ4 squealing noise

[kabs996]

Hello.....my 10 year old electric dryer is making a loud sqeualing noise upon start up, after about 5 minutes it goes away.  I have changed the belt and greased the wheels and motor shaft with no luck.  Anyone know what I should try next?  It is really loud but the fact that it stops after a few minutes is weird.  Thanks for any help.

First, don't grease anything on a dryer. It is not recommended and just attracts lint which over time will wear out parts and bearing surfaces quicker. 

Squeal noise is usually either the idler pulley/shaft or the drum support rollers/shafts. I'd advise replacing both on a ten year old unit. Could be the motor but typically it's either the idler or rollers, or both.

Whirlpool builds a repair kit for these...

4392065 is the part number. Buy OEM, don't buy on Amazon. This kit includes the belt, two rear drum support wheels, and a new idler pulley assembly. Clean the roller shafts for the rear wheels really well before installing the new wheels. I'd also have you look at the rear drum seal and if it's excessively worn change that, too. You'll already have the drum out so you may as well do a full tune up and clean up.
