2008 Chevy 3500 dmax steering problem

    I am having a problem with the power steering. On dry pavement with the plow up (9’ Fisher), not moving, the steering wheel will not turn and it feels like there is no power steering. However if the truck is rolling, plow down or the plow is not attached the steering is ok. I bought the truck new and never had any problem until this year.
    The dealer replaced the power steering pump which made no difference, now the service MGR tells me this is normal. I have a GMPP and I am assuming the dealer does not want to make another warranty claim for the same problem.
    Has anyone had a similar problem if so how was it resolved?

    Unless you psi test the pump output theres no real way to say what the psi is. But, for the most part its normal

    Sounds normal to me, my trucks do that too on dry pavement. Basically, when I put my Blizzard 8611LP on my Chevy 1 ton in the fall and pull it out of the shop, it's not turning unless its rolling. Very heavy on the front wheels, just keep some momentum backwards or forwards when on dry pavement.

    Thanks for the replies

    Thanks for the replies. The tire pressure is set at pressure the factory has printed on the door jam. There is no alternative for the plow. I am told over inflation will case other problems and can be dangerous.

    It’s interesting that others have the same condition, I think that GM under designed the steering box for the extra weight of the Dmax with the 9’ plow.

    I am wondering when the steering box will fail most likely when it it out of warranty.

    I am going to try to past in a copy of the GM TSB that make it OK.

    Just out of curiosity why do you feel the need to turn your tires when not moving?

    Thats not the best guideline to go by. Read your tire sidewall for max inflation pressure, usually 80 or 85 PSI on a LRE tire.

    Trying to turn your wheels on dry pavement with a plow on is just causing undo stress on all your steering components. When your plowing it's slippery and it's fine to do then. If you want your front end to last a long time take your plow off when not in use.

    Only turn your wheels while the truck is actually moving. Set your tires at max pressure or 5 psi less. Run synthetic fluid in your power steering system and make sure it is clean.
