So a couple weeks ago my car would start to fish tail when I would let off the gas. Now it’s fish tailing when I go over 40mph and gets pretty bad at times. Yesterday I replaced the rear sway bar with links and it’s still doing it. Pan hard bar was changed 5 months ago and shocks at the end of the year last year. Rear Upper control arms have never been changed and lower controls need to be swapped but would that be the reason to the rear end swaying side to side every time I drive?
