I previously had the common issue with the Vex offroad truck not turning correctly (Vex offroad Truck - Left and right not working) which was solved by Vex sending me replacement parts.
However, now the truck seems to be underpowered, or else something at the front is preventing the rear wheel drive from doing its job.
If truck turned on its back the rear wheels spin fine forward and back. The front wheels squeak a little, but otherwise turn without any problem. Put the truck right way up however, and it barely moves.
Ironically, before when I had the steering issue, truck would go back and forth at a good speed.
Anyone come across this, or have any suggestions? Thanks in advance!
