My original WE130 vice was making similar noises so I contacted Wicked Edge. They were very helpful and sent me the document that MarcH has referenced, but they also told me to look for scratches on the pedestal. I followed the instructions for disassembly and reassembly twice, both times polishing off the scratches that I found on the pedestal using 400 grit wet/dry paper. Unfortunately, the scratches came back a third time.
I contacted the folks at Wicked Edge and they sent me some replacement parts for the vice (if I remember correctly the pedestal and the washers). That solved the problem, and it hasn’t returned in the year that has passed since.
