Flaming river rack and pinion?

The threaded shaft is the tie rod.....it is on a ball socket (inner tie rod end ) under the rubber boot. It is suppose to turn / rotate. On a standard rack setup, that is how the toe adjustment is made.

Before you do anything....please make sure your rack is centered and the steering wheel turns equal amounts from side to side.

Are you sure the heim/outer tie rod end goes on the top? (looks that way in the picture)

Hope it helps.
