I have a 2014 Mustang GT convertible and purchased direct from Steeda a suspension kit for the car which included the following: Springs, Struts, Shocks, Front sway bar, Rear sway bar and Panhard bar. My local Ford dealer about a month ago installed all the components on the car. However, there is a crunching sound coming from the rear. The service guy told me this when I picked it up and said he installed everything per Steeda's instructions and was unsure what it might be. They told me to drive it and their hope was the suspension would "settle" in and the noises would go away. Now mind you the factory suspension never made a noise so I find this very unusual. I spoke to them Friday and told them it has not gotten any better, I believe it's gotten worse. The sound is made at slow speeds when the rear suspension has to flex, ie. going over a speed bump or if there is a great radial degree in the road it will make it then as well. I spend a lot on these pieces and for installation and it sounds like ****. The Ford dealer is trying to tell me this kit re-uses the factory bushings on the rear shocks and they believe that is the issue. I would say great, But they want to charge me $150 to put in new shock bushings. If that's not the cause, Then I'm out $150 and still trying to figure out the issue. I do not know a lot about suspensions and relied on Steeda to provide me with a setup and the Ford dealer to install it. Does anyone have any idea or advice on what I could do. I'm not a mechanic nor have tools, So I will have to take it to someone. I just don't want to have to dump another $500 in something that should of worked with what I already spent. Please help!
