Ok, i am coming to you guys for some suggestions. I have a rancho pro and for some reason when i accelerate hard it pulls to one side, very badly. I feel no binding, tires are tracking well. So i figure we can have some fun trying to diagnose and fix the problem. Make some suggestions, i will do what you say and tell you the results. Now when i brake its fine and when i take off easily its fine. Just when i accelerate fairly hard or hard.
