Replaced all four rollers on this older LG dryer. Now it runs so smooth and quiet! The front right roller had worn away the metal bushing/shaft over 20 years of use so it was wobbling to the point the dryer could not be used. The new rollers are really high quality and made the dryer run like new, actually better than new because the stock rollers were bushings (shaft/sleeve) while these replacements are actual sealed ball bearings. It took much longer to do this job than it could have because I took the time to clean decades worth of lint but overall it wasn't bad. The hardest part was removing the old rear rollers but with a little time and cursing, I was able to slip a flex-head ratcheting wrench behind the rear bulkhead to remove them.
