PEUGEOT 2008(2016 MODEL) CAR STILLS ON THE ROAD.

Hello everyone.

In May 2021, I bought my 2016 model Peugeot 2008 1.2 puretech allure while at 42,200 KM.
To summarize the problem; I have a hard time keeping the car in the lane. The vehicle usually pulls to the left, but this time the vehicle starts to pull to the right while making a small intervention to the steering wheel and trying to center the lane. While driving, it feels as if there is a jerk on the steering wheel of the vehicle.

I realized that there was a left pull when I drove the vehicle just before I bought it. I said it would be solved in Rot-Balance, I didn't have any problems. However, the problem was not solved even though I did not have the wheel balancing adjustment, renew the tires in original size and dimensions, and even have the canber-casters checked.

I showed it to Peugeot Mepa before. They couldn't solve it.
I asked the master while having new tires fitted and wheel balancing adjustments made, he said there is no problem.

Do you have any suggestions on this subject?
What do you think might be the cause of the problem?
What can I do for a solution?

There may be a gap in the steering box. There may be a problem with the swing bushings.
