Power window assembly rebuild
I just installed the front roller and roller & slider assembly during my power window assembly rebuild. I purchased all the parts from ZIP and found that the rollers are very stiff and do not roll freely. When test fitting the pieces together before final assembly, I noticed the rollers don’t turn inside the run channel; they slide which causes added resistance and which will likely cause the rollers to develop flat spots. It seems these rollers should turn freely. Many on this forum recommend adding a thin layer of white lithium grease inside the run channels. If I add grease, there will not be enough resistance and the rollers will never loosen up enough to roll. Has anybody else had this problem?
Thanks

Yes, the roller should roll freely. They are probably poor quality made in China parts. About all you can get these days. You can try turning them by hand to see if they will loosen up. You also need to put the grease in the tracks or the roller will wear out.

Gary, you are on target about the cheap material coming from China. But, I went to the NCRS webpage and seached their archive forum. I read the same complaint about GM replacement parts when these parts were still available from the dealers. My old rollers appeared to have too much wooble so I replaced them since I was in there. I should have left them alone. Some day I will learn that if it ain't broke don't fix it. I presume that the rollers are designed to turn easily. Other wise why have a roller.

The parts are not all made in China. Man this gets blamed on allot of items, we try not to buy anything from overseas, but sometimes this is impossible.
First the rollers are made just like the OEM, they are reproductions. The originals were also stiff and you have use lithium grease just like they did when they assembled the car for the first time. The rollers will loosen up over time.
