Front wheel not spinning properly after throttle is released (Ruckus 1/18 4x4)

[Trackpad]

My ruckus seem to pull to the left while in use, particularly when decelerating. when i pick it up and give some throttle all the wheels spin, BUT the front left one always seems to stop before every other when the throttle is released.
I've taken apart my front end and the front gearbox(?) (really new to the hobby, not sure of the terminology) where the driveshaft slides in seems to spin just fine and does not make any strange noises when spun by hand. the driveshaft also seems to be just fine. the bearings were my main culprit before taking it apart but i'm second guessing myself now because they both seem smooth?

any suggestions? I've seen a couple posts on here that seem to refer to similar issues, but i haven't found one where they had this issue with the front wheels, let alone only one.

thanks in advance!

Does it still do it with the wheels off?

You have a drag on front left. Do what @slick2500 said to isolate it being a wheel/nut issue of too tight. Do you have the correct pin and shim behind pin in, swap the bearings etc

You can pull the motor pinion off drivetrain issues are typically easier to diagnose if you can freewheel it
