    Default Upgraded Power Steering Pump 1991 Suburban

    In relation to a recent event that occured yesterday (see my blog about it), I'm in the market for a new power steering pump and pulley. I figured while I'm replacing it, I might as well replace it with an upgraded pump. So, does anyone know of an upgraded high-flow pump that would fit into the stock position of my 1991 Suburban with the 5.7L engine. It has the factory accesory brackets with the power steering pump on the lower drivers side.

    I'm not aware of any upgrades of this kind. Just replace the unit with a good quality replacement and you'll be good to go.
    Good Luck and God Bless

    OK. Thanks for the help. I might add a power steering cooler in, but it depends on how things go and how much time I have before I have to have this truck ready to roll again.

    After evaluating how much of a pain it would be to swap the power steering pump out, I decided I'd leave it and just replace the pulley. I left my truck keys in the picture for size comparison; that should be around 8" in diameter!
