My 1997 crewcab manual trans makes almost like a spring draging noise while turning but not all the time. It also sometime sounds like harmonics coming out of the steering box or pump. I am pretty sure my PS pump is bad and possibly the steering box too has anyone else had this issue.
Also I know the columns in the OBS trucks get loose but mine isnt wobbleing but when you shut the truck off the wheel dosent lock in place does this mean time to rebuild the colum.
Have you checked the covers over your steering column? i crawled all over my truck looking from a noise coming from steering.. Ended up being the cover rubbing on the steering wheel but for some reason sounded like it was coming from front of truck
