I’ve been having a problem with my steering wheel not returning to center or feeling no like I have no assist from like 10-2. The H2 is new to me, I had all serviceable parts in the front end replaced along with the left knuckle, and both hubs. Then for the alignment, the left me at like 3.75 caster. Still the same. Last night I dropped the skid plate and removed the stabilizer shock, checked the steering gearbox and set it for 1/4 turn out then drove it, still the same. Backed the gearbox off another 1/4 turn and drove it, still the same. What’s next?? We have any GM mechanics in this room???? This is a 05 SUV 35” tires on 17” rims.
