Sadly the new lower arms did not cure the issue.
The next step was the steering rack!
The rack is bolted to the front subframe and needs the S/F dropping out of the car.
New bolts and an alignment pin kit for getting subframe alignment right
Exchange rack ready to go
My gaff, glad I dug and made the pit, makes life a lot easier but is still not ideal. I'd love a proper garage with a ramp but what I've got is good for occasional DIY use.
Alignment pins, alignment checked before removal of the S/F.
Steering column clamp bolt. This needs to be replaced. There are actually two of them, one pictured and one on the riser bar off the rack.
Jacked up and securely supported
Coming down
Down and out
Cleaned an new rack on. Note the design height of the ARB
New water funnel
The new rack SORTED out the steering issue !
