I have an 01 TL that is aggressively pulling to the left. I have replaced the following (all four sides): wheels and tires (same problem with factory wheels and tires) struts, upper/lower arm, lower ball joint, cv axle, inner/outer tie rod ends, hub and wheel bearing, caliper, hanger, disks, brake pads, spindle nut, and a front end alightment (three differnet shops), tire pressure is equal all sides (35psi), i checked for a sticking caliper and everything is good. when driving staight (regardless of speed) it pulls aggressively only to the left side. under braking the car holds steady straight forward. The one thing I have not replaced is the knuckle. I have owned this car since new with 156K on it and it has never been wrecked. Does anyone have an idea on what is going on?

 

Have you examined the 24+ year old #10 & 11 left radius rod bushings (or their associated components below) to see if they have perished?

 

Great idea, I actually didn't think of checking those. Will check them out to see if they are good or bad.

 

It's hard to say without the readout from a wheel alignment; have you had an alignment performed and a picture of the readout?
