lmorris Posted May 3, 2012 Share Posted May 3, 2012 Posted in engine section, but seems more appropriate here. 2008 F250, lifted cab for a HPFP. Now I have a nasty vibration at 1500 RPM. Lifting vehicle on the frame will cause noise to go away, then I here a snap noise on light accell turning out of parking lot and noise returns. If you hard accelerate past 1500 RPM you will not hear/feel it. Tried retorquing body mounts on the floor and was no help. Will attempt to drive with mounts loosened to see what happened. Any input if greatly needed. Thanks. Edit: After removing lower portion of the body mounts I was better able to see that the front 2 bolts were not centered in the hole and were contacting the body. Re-positioning the body fixed the concern. Quote Link to comment Share on other sites More sharing options...
