2015 GMC Sierra 2500HD 4wd 6.6l Duramax LML Steering Issues

[bselff]

I have steering issues with it locking up while backing into a stall or pulling out and the steering gets tight and hard to turn. The dealer states no problem found. I have read some posts and think I may try the steering box, loosen and retighten. Any thoughts would be greatly appreciated

Loosen and retighten?  What procedure did you find?

 

A very common thing to also check is the lower steering shaft from the firewall to the gearbox.  The universal joint will bind and cause poor low speed steering.

 

If that's good, check all of your linkages (pitman arm, idler arm, center link and tie rods), you've possibly got a hydraulic issue.  It could be the pump, the hydroboost or the steering gear.

I had read on another forum that one person found that he loosened the gearbox, drove around a little and saw how much it had moved, retightened and that had alleviated his issue.

I sent GM an email, attaching the one I had sent when I only had 43,000 miles when it originally started to show up. The responded asking some questions, so I sent them a copy of the RO I had from them which stated NPF.

Waiting for their response now.
