If anyone has installed a "new" window motor in the tailgate of their Suburban, you may have noticed that there is very little engagement between the motor gear and the regulator gear. I think the motor gears and motor mount standoffs are just a little wrong. I cut 1/8" off of the motor standoffs, not including the little centering nub. If you count that, I probably cut off 3/16".
After I cut the standoff, engagement was good, but there wasn't enough room between the gear and the cover plate with the bushing. I did two things to allow the cover plate to fit and for the bronze bushing to still have enough support. I flipped the bronze bushing over, so the lip was on the outside. To hold the bushing in, I happened to have a starter shim lying around, and that was the perfect length to use as a retainer.
Here's a pic of the cut down standoff. I did all three.
Here's a pic of the whole install. Note the flipped end support bushing underneath the starter shim. I also added an extra ground wire since the regulator was kinda crusty and I didn't clean it.
I installed new rollers on the regulator. My regulator spring popped off, so I'm not sure how much tension it was supposed to have. I added 1/2 turn more than it seemed to want. This REALLY helped with speed and motor effort.
Below is how it works now. If you notice, at the end it slows down, where the spring is the tightest. And the spring tension really helps shoot the window up quickly. Before, at about halfway up, the motor would struggle to close the window. Now with the extra spring tension, I haven't had any more issues. I even changed my mind about running a new power wire and relays to the back.
