My professional wrench said he "neutered" the antilocks on half a dozen 97's and all customers were estatic. All got better braking and longer service intervals. The only problem is liability if there is a wreck at some point. If you do it for someone and then they run over a kid on a bicycle, they are going to blame the wrench. this needs to be done by the truck owner. My wrench showed me which wires to yank and let me do the actual deed. I have never regretted it.
My 93 nor my 2001 had these issues. Of course the 93 didn't have antilock and the 01 has 4 wheel disks. I believe the 97's probably have an issue. michael
