Product review (5 stars): Repair kit fixed my squeaking dryer.
This repair kit fixed my squeaking dryer!  It took about 1 hour for the entire job.  Rather than read the enclosed instructions, I followed along with this video ([...]).  For the most part this was a one person job, but I needed help (or longer arms) to attach the hitch and support.  Only one caution - the provided adhesive sticks good to skin, if you are a sloppy person like me, wear some gloves when applying the adhesive and felt.
