So the car has developed a pull to the right under acceleration, and pulls left under braking. I can't figure out the cause. Here's what's been done.

 

- All ball joints were changed last year and in good shape.

- New wheel bearings and hubs put in a few weeks ago.

- Tie rods and bushings are all in good shape.

- Track rod ends are in good shape, with left side newly replaced.

- No play in any suspension components with the wheels off the ground.

- No play in the steering rack with the wheels off the ground.

- No drag on the brakes, calipers were rebuilt with new seals and pistons last year.

- New CV joint on the left side. Right CV joint doesn't show any signs of wear.

- Same tire pressures all four corners.

- Alignment done last week with both sides even.

- Front subframe mounts are all in good shape.

 

Any ideas what could be causing this?

Have you tried swapping your front wheels from left to right to see if it has any effect or even swap wheels front to back

Uneven castor angles ? caused by a bent tie bar or adjustable bars not set up properly.

The last three cars I have set the caster on have all had the rods set at different lengths to correct the geometry.

Tie bars the wrong length and also wheel alignment.

Track rod ends should be done in pairs (as should anything suspension wise)

The tie bars are adjustable and an alignment was just done earlier this week with castor set to 3 degrees on both sides. I'll try swapping the wheels to see what happens.

Not sure if this will help. I had a similar problem pulled one away on hard acceleration and the other on lift off. All 4 wheels had been aligned. Everything seemed tight. This forum recommended recheck the steering arms. I found the two right hand bolts on the steering arms just slightly under torqued not really loose but a socket wrench showed an easy 1/4 turn. Torqued them up to spec. And the handling is back to normal.

If it's not the Steering Rack, check the bolts on the LH Steering Arm where it bolts on to the Hub.

They can be deceptive as they do stretch and so can feel tight, when they are not.

 

May as well check the RH one too.
