I have read many of the posts on this but can't seem to confirm so hoping to get a clear answer.

I have noticed a lot of tire wear on the inside of the rear tires. I know this is common but I also read somewhere that I should change the shocks to solve the tire wear problem. I had one out and it seemed to be in great shape so do I replace anyway? The car is an 06 GT and has 124 KM. I assume the shocks are not the originals based on their condition.

Also how do you know when you should change the sway bar links? I have the bushings on order to get rid of the rear rattling sound but wondering if I should change the links at the same time.

Any advice is appreciated. Thanks
