The steer gear on mine is a TRW HFB70 . I had it rebuilt at
Power Steer Inc.
Also, there are 2 ujoints at the bottom of the steering column that never get greased, & that could be the problem.
Also, the tie rod at the axle end of the drag link was bad.
Also, I had a loose wheel bearing.
Most of this info was previously posted for more details.
