One of the advancements in technology that makes the C4 such a great Corvette is the addition of rack-and-pinion steering. When these systems work properly, they're great. When they wear out, they start to grab and get stiff. This is often referred to as "morning sickness." Many times, the rack is replaced but the rest of the system is left untouched, often with remnants from the damaged unit still lingering.

All '84-'96 systems are basically the same, except for the steering-fluid coolers. The '90 Corvettes had noticeable shudder and moan problems, so GM installed coolers on '90 and later models to cure the problem. We went to the Corvette Clinic in Sanford, Florida, to get the full story on bringing a Corvette's rack-and-pinion steering assembly back to brand-new condition.
