I wrote in awhile back regarding steering sensitivity with my 89 suburban. Since then I have worked through the front end steering components. I replaced the steering gear box with a AGR gear box (not impressed) and replaced the inner and outer wheel bearings on both sides. The steering feels more sensitive than it did before. I have adjusted the gear box adjustment, but all it seems to due is stiffen up the return after turning. It has not helped with the tracking. I was wondering if there is a way to adjust the amount of assist from the power steering pump or at the gear box, or if there is any aftermarket equipment that would help. I would appreciate any help.

Thanks
