When driving down the road, the vehicle drifts and is difficult to keep going in a straight path. This symptom occurs while driving at any speed. What is wrong with the truck?
The steering has free play because there could be an issue with the linkage in the idler arm. In order to fix you can can either fix the linkage or replace the idler arm all together. You can buy a complete idler arm at your local auto shop. Just come in with the truck/car information and they should be able to provide a complete set with the bracket and everything already attached.
