Does your 74-89 911/912/930 have the common slop, wiggle and/or rattle in the steering wheel? This is a common issue with these cars and is the result of a worn-out OEM bearing liner. Rennline’s Steering Column Support Bushing installs in about 15 minutes and leaves you with a smooth/quite steering column. This is a big improvement over the factory replacement sleeve that takes hours to replace and is sure to fail again down the road.
