Thanks for all the tips. Just to close this thread out, I flushed the system. No change. Based on one of the earlier comments I checked the universal joint on the steering column to the rack and pinion. It looked ok, but just to be sure, I drenched it in spray lube. Problem solved. Was it the universal or the refresh of the PS fluid, I am thinking the joint looked good but was somehow binding. Thanks for the tips to look at the column joint.
