The steering is as smooth as it's always been to the left, but to the right it jerks and fights me turning right. The pump is less than 6 months old from doing the hydroboost conversion. Is it in the steering gear box?

 

Yes, that's a failing steering box. My 02 Tahoe did it too. I replaced it with the Cadillac p/n for the same year.

 

Yup agreed with Geoff. sounds like the steering box.

 

I guess I know what I'm doing this weekend.
