If anybody owns/owned an early 2000's+ Chevrolet truck or SUV, you're probably very familiar with the "bump" that I am referring to. The Chevrolet's would be fixed by replacing the intermediate steering shafts. Any similar issues with you guys?
I know what your talking about. A lot of GM's had that issue and it drove me crazy in my previous cars. Never had that kind of issue with any of the Ford's I've owned.
I also know what you are referring to, but have not had or seen this on any 11+ mustangs. Did someone remove the shaft through the firewall or at the rack at all? Also how many miles are on your car?
