Just got this car and I'm having some trouble. I am not new at this but I'm not an expert either.
After getting through the centax adjustment issues and tightening all chassis screws and adjusting some linkages that were hitting the reciever box, I finally got to break in the engine. It is on tank 4 now.
I am running Jaco foam tires shore 35 all around for now.
The problem is this. The car is all over the place. Cannot accelerate hard, it will just skoot to the side and spin out. Even on moderate acceleration it is almost uncontrollable. I have added rear negative tow in about 1 degree, although I know this is not the problem. I picked the car off the bench and when I spin one back wheel the front wheels dont' move. Also if I hold the one back wheel and turn the other it moves to easily. I think my differentials are too loose. Either built with no silicon grease or just not enough grease or too light of a grease.
Questions: Do you think that's the problem and if so can I add grease without taking the diffs out of the car. Can I take off the set screw and add grease or what?
I want to keep this car basically stock, it should be much better than it is with the soft Jaco tires.
