04 ram1500 awd. vibration on acceleration

Hmm, when I had my 04 1500 4x4, the tire shop got it leveled out by just cranking up the bars, no kit needed. Never had any vibration issues.

yes, awd as tmccuda said. no 2wd option. lift is higher than stock torsion bar set up would do. truck has new tires and stock wheels (20"). tho they are 275 65 20 instead of 60 series. unfortunately wont fit on stock ride height( so im told).had vibration with old tires also. vibration starts at 10mph on up, whenever on the gas.suspect is frt 1/2 shafts,but can only find aftmkt correction shafts for 06 and up (kore). any of u truck guys know of any other axle companies. as I said before, lift looks like torsion bar keys and rancho shocks. nothing involving differential or control arm mounting points. ride height is more like 2500 than 1500. truck is not skying.im figuring not too commonly reported, due to truck being awd. thanks again for the input from everyone, gregg

Remove the front drive shaft and take it for a ride, see if the shake goes away. If it's gone, then you know it's the front drive line. Don't leave the driveshaft shaft out though. Just for a test.

How many miles? As said remove the front shaft and try in in 4wd. You can also do the same on the rear. You may have to clamp a small plastic jug on the tail shaft housing for fluid loss. I will just about bet the vibration is in the front or rear shaft. Remove the shafts and feel the joints. Its either a tight rear joint or bad front shaft couplings. Remember the drive shaft is spinning 3.5 to 4 times faster than the axles.

YES. already had removed front driveshaft, and vibration was gone. talked with ready-lift. they said cant raise awd for just this reason. anyone know a company that can alter these or offer new half shafts (axles) with better operating range. thanks again,gregg

I think you have to replace the front drive shaft. There is only a single u-joint at the diff side of the shaft, the xfer case end has a sort of CV slip-joint deal. That is where mine wore out and I had to get a new/ reman from Carquest.

Balancing wont matter when Xfer case end is worn.

as I said, already had frt driveshaft checked and balanced. suspect half shafts vibrate only with torque on them. much like a u-joint on a rear propeller shaft. any way, lowered frt end tonite, as low as kit would allow, and vibration is gone. gonna see how much height I can get away with tomorrow, then recheck alignment.will post my results. thanks again for all the input, gregg
