'97 Chevy Suburban 1500, Steering Drift

Q: Jim, I own a ‘97 Chevy Suburban 1500. Since the first day, we noticed that the steering was extremely easy. We also noticed that while driving down the highway, the truck drifts right or left. You are always steering to stay in a straight line. Would a Steering Stabilizer help with this problem? Otherwise the truck is great.

A: Actually your complaint is not uncommon. ALLDATA Information System shows Technical Service Bulletin (TSB) # 76-30-01 addressing a vehicle owner’s complaint about steering that may seem to wander or be perceived as too loose at highway speeds. The TSB wants the technician to inspect the front end for any binding steering or suspension components. If any components are found to be binding or loose they should be lubricated or replaced as needed. If this does not correct the problem the alignment should be checked and set to the specification outlined in the TSB. If all is found to be correct the problem may be in the steering box. Depending on the Gross Vehicle Weight (GVW) the corrective repair may require adjusting the spool valve preload or replacing the steering box. The spool valve is a part in the steering box that controls the flow of power steering fluid to the assist part of the steering box. The adjustment procedure reduces the sensitivity of the power steering. Of course the replacement power steering box addresses the problem as a complete unit. Some diagnostic time will be needed, but you’re not being over sensitive, your steering is.
