Restore steering function in your 2007.5-2010 Chevy/GMC 6.6L LMM Duramax with a new Steering Shaft. Replace the worn component in your vehicle with the direct-fit couplings, intermediate shafts, upper or lower steering shafts, or repair kits available. When the u-joints in your factory steering shaft wear out it can lead to steering problems like a loose feel in the steering wheel or misalignment. Replacement Steering Shafts are available from top industry brands including Borgeson and Dorman.
