My tailgate window is extremely slow to go up ..The motor in there is only a couple years old and not used that often .. And I have lubed the regulator and guides a while back .. I was thinking of swapping out the motor again .. Any suggestions on where the problem may be and does the Dorman motor have any more torque than the Ford style motors ?

There have been a lot of issues surrounding the repair of the rear window motor.
Now, when mine finally went out, the motor would spin but, the window would not move.
Many of us have had this same problem. I will not be discussing the removal of the regulator at this time.
First, but the repair kit. There have been talks about using several 3/8 nuts for this but, I was still leery about that so, I decided to just pick up a repair kit from Discount Auto Parts.
Dorman part number is 74410
BEFORE YOU TAKE OFF THE MOTOR, MAKE SURE THAT THE REGULATOR IS ALL THE WAY IN THE UP POSITION!!!!!!!!!!!!!!!!!!!
This is for your safety. You can very easily break your hand if you do not do this. Notice that my regulator is NOT in the full up position at this time. Once I pulled the motor out, the regulator “snapped” up with a LOT of force. I got lucky.
Lubrication Discussion; "...90% of you all probably already know this so I guess I'm talking to the other 10% of us who don't/didn't. My rear window has been giving me problems for the last 4 months. It would go down a few inches and it would get stuck. Then I would either have to rock the dash switch back and forth to get it to go down or go to the back and use the key with one hand and push down the window with the other---Very frustrating. FIX: 1) First roll down the window, drop the gate and take off the inside panel (about 8 philips head screws) covering the tailgate. You will see pretty much nothing but glass after doing this. 2) Then manually flip the latches so you can use the key to roll the window back up. ***Very Important*** Put something under the window to support it--sawhorse, lawnmower or whatever. The weight of the glass could cause it to break when rolled up with the tailgate down. 3) After the glass is up you'll have access to the inside mechanisms. If you bend over and look at the underside you'll see a couple of arms that attach to two 6"-8" pieces of channel. These arms move along the channel to raise and lower the glass. 4) Get some grease and smear inside both channels. You don't have to glob it in there just put enough that it goes completely on and along the inside of the channels. 5) Roll the glass back down. 6) Put your inside panel back on. 7) Pull your tailgate release handle one time to make your latches go back to the open position and close your tailgate. 8) Now roll up your window and see if it helped any. Mine goes up just as smooth as ever now. It doesn't slow down a bit. Now this may not work for everyone but it sure worked on my rig. Brian..BTW, this took about 45 minutes start to finish...."

The window glass mechanism should be lubricated whenever the glass channel or window regulator is removed, or excessive effort is required to operate the windows. To lubricate a door window mechanism, apply an even coating of Multi-Purpose Grease D7AZ-19584-AA (ESR-M1C159-A) or equivalent to the window regulator rollers, shafts and the entire length of the roller guides

I would more suspect that the cause is poor electrical connections. You can check thet by using a 12V battery and jumpering direct too the motor leads. If it is still slow when you do that, it could be binding in the track or the lift gear, or the motor. However, without seeing it, I'd bet on bad connections. You can also test with a meter at the motor to see what the voltage is when someone is operating the control. You should have close to the battery voltage when engine is off and close to the charge voltage, (about 13 to 14 volts) with the engine running.
If you will notice, the ground circuit has to run the full length of the truck 2 times as it is done through the dash switch.
