howdy to all just found this site looks great. I have a 1998 tahoe problem is that sometimes when I am driving it the steering wheel jerks to the right ,usaully on a right turn but did it once in a straight road. is this the start of a steering going out, if so what can I check out or replace . I am a mechanic on a helicopter so hopefully I can fix it myself if pointed in the right direction. Thanks a lot Bob W.
