HELP!! 2005 Pete with Vibration

Check your drive line angles. Ride height will change your drive line angle and cause a very bad vibration. Had a customer that replaced the clutch, transmission, remove and check both again to find nothing, roadtested it with him and it would take the shifter out of your hand a 55 mph. I dropped his rear air valve one inch, vibration moved up th 65 mph. dropped it another 1/2 inch, vibraton gone.

 

How long have you had the vibration. Do you have diff temp gauges and are they high. Had a truck come from the factory with the front diff a 3.55 and the rear 3.70. It got about 150 000 kms on a front diff before failure. After the front diff failed twice the dealer caught the mistake and repaired under warranty.

 

Are you talking about the damper on the front of the engine? Most will hear a front drive gear noise before you would feel a vibration. Did you have the flywheel machined, what happened to cause the vibration. Not to scare you but have had broken crankshafts very hard to diagnose. Had one that the dyno operator replaced a set of injectors before he found the crankshaft broken. is your front or rear seal leaking at all?

Also, have you had the top end set? the intake actuators can cause a vibration.

 

On XM radio awhile back TMC tech talk was talking about vibrations in a pete. Maybe you can find some archives on that.

 

When did this vibration start, right after you put the new clutch in? Did you have the driveshafts balanced?

Any tires wearing funny?

If it was the dampner wouldn't he start breaking flywheel bolts?

 

does this vib happen at any speed under high torq? or just higher speeds say 55 and up?
