I recently replaced a power steering pump on a GMC Yukon XL after it came in with the complaint of no power assist (power steering). the following day the customer contacted me and explained that the power assist would sometimes fade while at highway speeds. After some quick checking I decided to do what I should have in the first place and deleted the variable power assist entirely. Removing the variable assist system can be accomplished a couple different ways and ill give you a quick rundown of what you need and what works best in each case. This video tip is relevant to both Chevy and GMC cars, trucks and SUV's including Chevy Silverado, Chevy Tahoe, GMC Sierra, Yukon, Cadillac Escalade and other GM vehicle equipped with the infamous variable assist power steering system. This video will also be helpful for those simply wanting instruction for replacing the power steering pumps on these vehicles with or without the variable assist option. Watch this video for more information.
