Check your cross member location - your TCA mounts to this.
A little bit of displacement here relocates the inner mount for your TCA forward/back with your lower ball joint moving in the opposite direction. Basically your swaybar acts as a pivot point.
Other point to check is the front swaybar to chassis mount bracket, not the 'D' bracket, the part that bolts to the front corner of the chassis. If displaced the TCA moves backwards/forwards correspondingly.
Assuming your chassis structure is straight some quick measurements will tell you where to start looking, if it is out enough to pull to the left you *should* be able to see some variance in measurements with a simple tape measure and a reliable assistant to hold the other end..
- Measure from front crossmember to front of rear spring mount on both sides - this will identify if your crossmember is displaced; if OK, then
- Measure from front cross member to front swaybar mount bracket - this will identify if your swaybar mount bracket is displaced.
As an aside I assume you have already tried loosening and resetting the upper strut mounts to relieve wind up tension - in my experience the number one cause for steering pulling in the Escort?
