Product review (4 stars): Quick & easy fix for a horrible dryer squeak
GE dryer is ~16 years old, started making a pretty bad whine/squeak about once per revolution. Repair man said it would be about $200 to replace the entire front bearing assembly (if the diagnosis is that you have "bad bearings," it's probably these lubricant strips for a bearing surface...not ball bearings). He claimed you can't replace only the bearing strips. No thanks, I would either figure it out myself or replace the dryer. I bought 2 of these strips and 2 other strips - it wasn't clear which is for which spot (high or low) but I believe they're all interchangeable. Anyway I took 4 the old bearing strips out (actually 1 or 2 were missing, hence the whine/squeak), put these in (had to super glue one of them in because the hold-in tab on the dryer was broken), and it works just fine, cured the squeak.  Wish I had tried this first instead of paying the guy $80 to drive in my driveway and try to get me to overpay even further....  Lots of vids out there on how to take the front panel apart from the dryer drum to get to the front bearing.  A very cheap and easy fix when your dryer sounds like it might self-destruct.
