Dryer squeeks already changed bearing

Morning. for the past 3 weeks my dryer started to squeek when turned on. It starts out loud in the beginning but eventually gets lower when it is running for a while. I read some forums and decided to change the bearings. I purchased a bearing kit AP2619300 and installed it over the weekend. When I first used the dryer after the new bearing was installed it was fine, now after 2-3 loads it is squeeking again. I did some more research and now it says to change the Dryer drum slide AP2041815 & AP631382. Do you agree? If so, how many should I order & what colors? It recommends to change as a set! Any other suggestions you may recommend? Thanks Jerry jtatonetti@aol.com

Hi Tom, When you say replace all 4 what exactly am I going to order? 2 of AP2041815 & 2 of AP631382? Thanks Jerry
