Hope you guys can help me out again,I know this isn't SuperCoupe related,but maybe some of the Ford technicians have experienced this before...
2000 F150,SuperCab,5.4,Automatic,2wd,Gibson shorty headers,Magnaflow(Lightning) exhaust,117,000 miles...
I have an irritating moan/rumble/buzz that resonates throughout the cab and can also be heard at times outside the cab.It only does it at idle or just above idle in gear,doesn't matter whether its in drive or reverse.I can duplicate the noise by just barely touching the accelerator with my foot on the brake or with the e-brake.It is below 1000 rpm's and reverberates like a subwoofer.I have removed all of the heat shields above the exhaust,loosened clamps and retightened,loosened engine and trans mounts and resettled them,removed my bedliner,and installed an additional vibration damper further forward of the original.This has been happening for a while,but has progressively gotten worse.
One thing that I did yesterday was to put a jack under the exhaust hanger/isolatator bracket that is mountedalong with and above the transmission mount and the vibration went away.I know it sounds like I solved my own problem,but has anyone else had this same problem???..Can I remove this hanger without risking damage to something else???..I've searched,but is this a common problem,or should I just replace the hanger???.. Please help me out..!!!
