I have a 98 Chevy 2500 pick-up, 4×4, 7.4l With the abs fuse out and the plow on or a trailer in tow, the steering has been locking up when I come to a stop and the brakes give a little like they dont want to stop. With the abs fuse in and the plow on or off the steering doesnt lock up but when coming to a stop the brakes loosen up at the last part of the stop, but still stop. I have recently replaced both front and back brakes, bled and rebled, replace hydro-boost unit, and replaced two bad brake lines one regular and one from the abs unit. I am comtemplating changing the powersteering pump because sometimes the steering is hard when it hasn’t warmed up enough, and the pulley has been whining even though the belt is good and tight. The abs fuse hasn’t been in for about a year cause the previous owner said he took it out cause it was better to plow with it out….but I recently put it back in cause of the steering locking up when braking….sidenote…even though I changed all the brakes, and lines, and bled, and bled, and replaced the bleeder screws it still didn’t seem like the brakes were strong enough. PLEASE any information or opinions you may have will be greatly appreciated…Thanx..JR
