1998 power steering

[CharlieM]

I am having some issues with my 1998 suburban power steering. Replaced the pump a couple years ago and ever since it feels very light at highway speed but very stiff when moving slower around town. The pump also whines pretty bad at higher rpm’s. I now have the engine out for a rebuild and want to get the steering figured out. It has just over 300k miles on it so I was thinking about putting a new gearbox on along with another new pump. Is it possible to install pre EVO parts on this to avoid future headaches? Thanks

Sounds like a defective pump.

Does this vehicle have Hydroboost brake assist?

I was thinking about putting a new gearbox on along with another new pump.

Don't let your original steering box go back as a "core" until you're satisfied with the "new" steering box.

Is it possible to install pre EVO parts on this to avoid future headaches?

Sure.

It does not have hydro boost brakes.

what years of pump/gearbox combo would I want to use to get rid of the evo system?

Gearbox doesn't matter. No difference that I know of between EVO and non-EVO in the gearbox.

Pump and hoses would be '96, as EVO started in '97.
