Ok after reading everything that you have posted I would recommend you getting a few more things checked:

I would suggest bring it to more intensive and precise automotive service center .another solution would be replace all the suspension mechanism in front, replace all the disk brake mechanism front and back, and the last try buying 4 new tires have it aligned properly..hope this help. thanks for using fixya!

Your problem sounds like a faulty brake caliper. You describe a pulling while pressing the brake. I'd look at the front left brake caliper. My guess is that it's frozen (not fully releasing when you take your foot off the brake). It's possible that with all the parts you had replaced that the problem was less pronounced due to all the other issues you were having with the tie rods and ball joints. Assuming your tires are fine after all the front end work, you car is displaying classic symptoms of having a frozen brake caliper. When you corner, the car slows down making the pulling more pronounced. A bad caliper will wear down the brake pads faster. I'd have the brakes inspected at another shop.(shame on Sears for not doing that already) I hope this solution helps with your issue.
All the best!

Check your radius rod bushings. One side may be worn/damaged/loose allowing one of the wheels to move foward under power.
I would also check the engine/trans mounts. Too much movement can make torque steer worse.
wheel balane has nothing to do with a pull..........
bad tire, alignment out of specs, worn suspension parts will cause a pull.
you might want to switch the front tires side to side and retry it check tire pressure as well.
Also - the right side is the short shaft. If the left side CV joint(s) are worn - this could cause the short shaft side to have more control. (ie. the turning problem, and drifting on accell. and stopping)
STEERING WANDER The vehicle lacks directional stability and wanders or drifts from side to side. Possible causes include:
Loose or worn steering components. Inspect the tie rod ends, inner tie rod sockets on rack & pinion steering units, and the idler arm and center link on parallelogram steering. Check the steering column couplings. Also check for loose or broken rack mounts. Check the amount of play in the steering rack
or steering gear. Lateral play at the edge of the steering wheel should usually be less than 1/4 inch (always refer to manufacturer specifications). Replace worn parts and/or adjust rack yoke or adjustment screw on steering box to reduce play.
Loose or improperly adjusted wheel bearings. Check and adjust wheel bearings to specifications.
Insufficient caster. This may be due to increased ride height at the rear of the vehicle (raising the rear end with air shocks or air springs) or lowered ride height at the front of the vehicle (weak springs or shorter than stock springs). Increase caster and/or reset to specifications.
Extremely low tire pressure. Inflate to recommended pressure.
Extreme toe misalignment. Check the steering linkage and adjust or repair as needed.
TORQUE STEER The steering veers or pulls to one side during hard acceleration. This is a common condition in front-wheel drive cars with unequal length driveshafts, and is caused by unequal toe changes as the suspension is loaded. Compliance allows the wheel with the longer driveshaft to experience less toe-in change than the wheel with the shorter driveshaft. This causes the vehicle to veer towards the side with the longer driveshaft. FWD cars with equal length driveshafts usually do not experience this condition.
Torque steer cannot be eliminated, but certain conditions may make it worse:
Loose or collapsed control arm bushings.
Loose or worn tie rod ends.
Loose or worn inner tie rod sockets.
Loose or broken engine/transaxle mounts.
Vehicle manufacturers have offered various repairs to reduce the severity of torque steer in some FWD cars. The corrective measures include using stiffer control arm bushings, shimming motor mounts, realigning the engine cradle, replacing the motor mounts with stiffer mounts, or increasing cross-camber.
