I bought an underdrive pulley for my truck and put it on last year, but noticed halfway through the summer I was getting a weird notice while sitting at lights, then it started doing it all the time. Startup, idling, but would go away during accelerations over 1400rpms. Under hard accelerations it would squeal like it was slipping really badly. Then I took it out the other night and was driving on the highway, and it just squeeled for about 10 seconds at a cruise of 100km/60mph. I haven't driven it much since, except to the car wash, but I switched it out today for the stocker and stock belt, no noises. Has anybody else experienced this? I also never noticed a SOTP difference between stock and underdrive in acceleration. Just noise.
