Creality hi combo- printer bed bearings & a solution Ifound for ghosting

First I was having Ghosting & such- The extruder carriage bearings were bad. If you’re having issues with your prints that you can’t figure out, Check for movement on the extruder. I replaced mine with an upgraded carriage. Great prints.

Today the print bed bearings started screaming. After pulling it apart, I found that they were installed over tightened. Can someone point me to where I can purchase some replacements?

I found the replacements.- They’re SG15 U-Groove bearing- 5x17x8/9.75mm.
