Vibrating Gear Change
 

Hey all I have a 1995 F350. I repalced the engine two weeks ago. A 7.5 gas. The truck previosuly vibrated some because of the guy who put calcium in the tires for snowplowing. Well I know that may be the sole problem for the vibrating, but I think it has more to do with something and that complimenting the problem. When I hit the gas it goes into a shaking crisis, the dash is vibrating, and it does that for ever, theres no point realy when it smooths out unless I let off the gas, I dont think its the tranny, I just had that checked and they said nothing, but it was VIP and they usually dont lke to deal with that kind of stuff. I want to replace the shocks and tires, I think that mite help, also gettin the exhaust switched out for a flowmaster.

RE: Vibrating Gear Change
 

Does this engine 'vibrate' if you just bring up the RPM's at any/all ranges while stationary? Or is it just while driving, and 'speed related' sensitive? Anything in the driveline/shaft or tire/rims wouldn't/shouldn't vanish if you back out of the throttle suddenly, unless speed is lost as well.. (Manual trans?) A unmatched/balanced flywheel will cause bad vibrations at all ranges, both at speed, and ranging the RPM's in a stopped position.. You make 'more' mension of the dash vibrating than a bad steering wheel/head shake, and at all speeds which if it were a tire/alignment issue, it would shake, but usually will be at a specific speed, and also usually not present at slower speed.. The dash attachments at the door/cowl area do like to break (especially the right side) and the dash will 'bounce' magnifing the issue..
