2001 tahoe steering problem

Hello i have a 2001 Tahoe with a steering problem..when i turn to the left steering feels fine when turnign right at low sppeds feels like steering binds or has no assist. at times.. I have replaced evo sensor, pump disconnected evo solenoid on pump yet problem is still there

thanks for your help

Interesting, same problem just surfaced on my '98 a week or two ago, exactly the same actually--easy to the left, hard to the right at slow speeds--like the power steering isn't kicking in correctly. I just assumed it was EVO since I've had problems with that before, but I guess your case shows otherwise. Shoot a post if you figure anything else out and I'll do the same.

thanks i will its driving me nuts

What's the correct name for the EVO? What's the part number? Does anyone other than the dealer carry it?
