C1 Corvette Steering Gear Restoration
|
Prior to operating the gear, fill the housing with lube. For a moderate climate, use a 90W-120 or similar EP gear lubricant. The factory fill was "SG" (steering gear) lubricant, similar to 90W gear lube. Multi-viscosity lube provides better protection when the engine heats up the steering gear. After driving the Corvette briefly, check and top off the lube to the bottom of the fill hole threads. While chassis grease is often added to offset a leak problem, the modern sector seal should retain gear lube for many years. View Related Article
