Thumbs down front motor turns the wheels slower than the rear...

one of my motors has a noticeably significantly slower turn speed when the tires are on. its the front motor so when I'm wheeling in the snow, my back end digs in because the front doesn't grab enough to get over the ruts the truck makes as it breaks trail. i reversed the plugs so the faster motor is now in the front, but I'm confused as to what the deal is. i did some diagnosing and its definitely not the gears.

anyone have a diagnosis as to what it is with the motor?

That was my guess too. I took the motor off and ran it through water to clean it. It seemed to make it better, but went back to running slow the next time I took it out.

Did switching the motor wires make a difference what motor went slower? Or is it just textbook clodstall?

Clod stall is from what I understand the rear motor going slower under weight. This is the front motor going significantly slower than the rear in a free spin at full throttle, and it wasn't this bad when i first got this rig. I probably wouldn't have even noticed it had I not been wheeling in snow since i got this rig. Where it used to push through snow until momentum stopped and wheel spin started to dig in, the front would no longer grab and pull past where the wheel ruts ended and the back end digs in before the front (you can visually see the front was spinning slower). Switching the polarities of The motors so the rear is now front has made a dramatic difference in performance on the snow, but the one motor (originally the front, now the rear) is still noticeably slower but not such a big deal now that the front gets the spin and grab power it needs

Needs new brushes? If the motor does fine when it's not on the truck, it could be a stripped gear or maybe a pin fell out?
