On my 2005 4x4, what should the Caster be set at for the best drive?. It is all stock, no lift. The specs show 4. 0 to 5. 5 degrees, I am at 4. 6, and it doesn't really feel right, like it wants to over steer a little. Also the toe, the specs show -0. 3 to +0. 8, mine is 0. 1 on the left and also the right. The steering is real touchie.
