Twice in one week my 2004 GMC Canyon coming out car was turning onto the roadway under power ,my steering jerked out of my hand and almost control. What the problem?
Check the fluid and see if it’s low.
If your fluid is good and problems persist it could be the spool valve in the steering rack. This valve directs the fluid to the correct side of the rack when you turn the steering wheel. If this is the problem you need a new rack.
