Recently my x3m has an accident, I drive car want to left lane change, but hit the car on the left，my car's left rear suspension was broken.
To fix it, I replace the Left lower swing arm with a new one.

But, when the car is repaired, I found the car go deviation and steering feel bad.The car can hardly travel in a straight line, I have to adjust my Steering wheel often.

I bring my car to bmw repair shop to do wheel alignment and clear steering memory, but the problem still have.

Finally, I have to do Cable four-wheel alignment to fix the problem.

Thank goodness, my x3m steering feel good as before, and the car can go straight line again!

If I am reading this correctly you had a bent frame and getting that straightened was the final step in repairing your car. Glad you got it fixed up!

Getting the swing arm straightened was the first step in repairing.Finally I have redo the Cable four-wheel alignment to fix the toe angle not correctly.

Was the swing arm (control arm) straightened or replaced? On an expensive car it's much better to replace these parts than to bend them back into shape. A part that was straightened won't have the same strength and probably not the same shape as a new replacement.

The swing arm has been replaced a new one, bend them back is not a good idea.
