Problem with the inner and outer tie rods where they meet the hub with their ball joints being worn ?
Or the control arm ball joints not moving correctly?
If you jack the front of the car up does it work with less pressure on everything?

Ball joints corroded with rust instead of grease as above post /

Hello and welcome .

If you have had a new rack fitted it would also have new inner tie bars fitted (they are cheap) I have just replaced mine , installed new gaiters (all Lemforder) , the rack was fine but I removed all of the grease that I could get to and replaced it = super smooth. It should look something like mine shown here.

Who supplied the rack ?

I thought a new rack would heve come fitted with new tie rods any way

My point exactly . The new rack would have been complete with inner tie rods and gaiters , a pretty straightforward job for any mechanic hence me asking OP where the rack came from.
