truck: 2006 dodge ram 2500 mega cab heavy duty cummins

So guys i got this situation goin on,

under no load when i accelerate i get a bit of a shake and it goes away once i get going. when i have a trailer or any type of load the shake gets big like it shakes a lot but then goes away once i get going? i cant figure it out

 

Sounds like axle wrap. Do you have a lift with blocks? Broken rear leaf springs?

 

nope shes all stock just a level kit in the front and sittin on 315's

 

so its when the engine is at low rpms?..annnd WOT or just regularly accelerating?

 

just accelerating has nothing to do with RPM but the harder i press the gas or if i have a load it will shake harder drives normal after about 5 kmph

 

axle wrap only happens on hard acceleration and from a dead stop, not wile cruising.

The 2500's have 2-piece driveshafts that have a center carrier bearing. i would crawl under your truck and shake your driveshaft where it enters that bearing and see if there is any play. It shouldn't move at all, so a slight clunk and it's bad.

if it's not that, then your torque converter may be the problem. How many miles are on it?

 

ill go check right now and only 150,000 kilometers

 

This sounds like it could be a broken trans/eng mount. How about putting it in gear with emergency and foot brake applied and running the engine up some (power brake). Don't spin the tires but put a strain on the engine and drive train. If the engine is missing under load it will show up. If the engine isn't missing then have someone look to see if a mount is moving. Be careful and don't run over anyone.....

 

IDk but lets see if other CTD guys can help him out.

 

like stated before, its either the carrier bearing, torque converter, the only other possibility is a failing u-joint, set the e-brake, and put the trans in nutural and move the drive shaft around to see if anything is loose
