I think this may be outside the normal range of alignment jobs that tire and alignment shops usually deal with, and any information or suggestions that I could go in there with would help in getting this worked out. The also said that the recommended range was something like 4.2-4.8, if I remember correctly.Ĭould this caster setting (both before and after the current alignment) be what's causing the drifting? If I raise the front spring height, could that help get it back in range (I have adjustable Aldan coilovers on the front, so I could easily raise them by 1/2' or so)? Or might the vehicle need different upper control arm bolts in order to get the caster to another 'range'?Īny advice folks could offer would be of great help.

Its all in wether or not you want that truck payment.

Either way, NBS or OBS, its still a Chevy, and it will look better then every other truck on the road :imo. The way they redesigned the front suspension makes it VERY easy. It was - and still is currently - set at 5.1 left and 5.9 right they said that was the 'best' they could do. A buddy and I put a lowering kit on his NBS. The caster seems to be the only thing that is somewhat our of reguar spec. 1500 1994 1995 1996 1997 1998 94 chevrolet chevy obs pickup silver truck.

And this is AFTER another front end alignment. The truck is still wandering left or right, and I have to gently correct.
