Review on 🚗 Dorman 748-561 Rear Passenger Side Power Window Regulator and Motor Assembly for Dodge/Sterling Trucks - Black Finish by Dre Fowler

The product arrived in good condition. I removed the old block and installed the new block. The device fit except for the lack of a fastening screw. The block is made in China. My old nuts and bolts were fine, so I pressed the correct bolt into a vise. After the device was installed, it rolled down, but sometimes I had to help it to get it rolling again. So what is the guarantee for this chopstick set? I checked it several times for binding, lubricated the rails with the correct grease, sprayed Teflon grease on the window seals and lubricated the pivot points on the hardware. The engine appears to be misaligned. It rolls down like a 2500rpm drill with no power to get back up.
