I will check inside the rack boots tomorrow, in case a joint has come loose- although fact that track is correct would suggest otherwise. Maybe need to order another pair of TCAs as well........

Frustrating!
Mike:

Don't throw good money away!

Checks:

1. Rack Ends and Rack itself:

Ensure rack float is not excessive; disconnect track rod end joint: check sideways movement this at lowest, middle and top angles. Then rotate 180 deg and check again.

Test TREs in a similar fashion, rotating them before loading them.

Not unknown for thrust washer to wear, remembering they are a sacrificial component and competitive usage places much more end load and thus wear on the part.

2. Bottom Ball Joint: a primary suspect! Disconnect from bottom and using a long lever, move it both up and down (Replace the nut with a much larger washer). Small amount of wear is magnified through the suspension.

3. Test the rims for rotational "wobble": can be done on the car, all provided the wheel bearings themselves are not too worn. Ideally with a Dial Gauge: however, a fixed point at the periphery of the rim can show up significant "Run Out".

Come back with results!
