Ed:

Agree with comments that you need alignment performed to ensure your rear end is right. I believe you are located in Asia where highly trained independent tech isn't available round the coner. I will advise you take your car back to the dealers to get it measured properly. The low end equipment some of these techs have are not enough to do a proper job. Perhalps not the case for 124 but definitely for 140. They can't even do the wheel balance properly.
