Hot bodies 1/8 diffs

I got to take it out and I'm having a problem with the truck pulling to the left. I have the wheels pointing dead straight. It seems that the servos don't want to center. They will center when I give the wheel a quick turn left or right a few times. That is fine when sitting still, but if I have to do that when the truck is up to speed that will = a crash!!!! I guess I'm going to have to wait till the Hitec 9380's are released:(. I will tell you guys it sounds really cool when running, much different than the stock brushless. It will pull the wheels off the ground at will. Even though it has all metal gears it is not as loud as my stock truck. I'm just afraid to bring this thing up to speed if it's going to act all squirley. Yes I did center the servos when mounting the steering linkage. I don't have another set of servos that I could use, and I don't want to buy something that I won't end up using later.If I adjust the trim when the servos truly center they will pull the side so I don't think that would be the solution. The servos are Hitec HS 5625's. Any thoughts guys?
