Thanks to Trikyrix for helping out.
I needed to swap out my door weatherstrip (torn) so yesterday we went one step further and pulled my window tracks. They were full of hardened grease. We cleaned them out with Carb Cleaner and regreased them with bearing grease.
I didn't use Lithium grease as it just hardens rather quickly in my experience. Plus, when Rick got his new regulator from the dealer, it looked to have standard grease in it.
We used a very light coating of grease much like his new regulator.
The results are tremendous. The windows are nearly as fast as a new car. They still are faster when using them one at a time but that seems more like a power issue.
Next option to get full speed may be to wire in some relays and supply power direct from the battery as discussed here.
