A suspension refresh meaning replacing certain parts of the suspension; such as struts, control arms, wishbone brackets & bushings. I don't think it's necessary because of the low miles that are the car. It really is a mystery to me considering how many parts you've already replaced.

 

Initially i suspected it could be the coil spring however many mechanics told me there should not be any issue or major wear & tear with it as they normally last for a very long time

I also suspected the way the mechanics assemble the parts maybe it's incorrect however when I brought my car to another workshop for an inspection, they told me the parts were properly assembled.

Everyone told me it's in my mind but i know it's not as the effect is apparently quite obvious to me
