Need input:banghead: Working on a 2002 Dodge Ram SLT 1500 4X4, Has Vibration under throttle only. Things already checked are as follows: Ignition system, U-Joints, Rotors/Pads were extremely worn replaced (no-help with vibration) Fuel/Air filter checked good, scanned found no codes, Truck runs and drives/shifts well pulls well, just mysterious vibration felt upon accelerating. Also checked hubs, tie-rods cv's in front rear axle bearring, have noticed can feel vibration more through transfer case lever as well, wondering if anyone has experienced this, thinking only, not tested ( torque converter/tranny/transfercase) any suggestions would be greatly appreciated.truck info 4.7 Magnum V-8-factory wheels firestone tires in good shape, shocks etc. 127,000 mileage recently complete tune-up, no help for vibration.

The drivelines may need to be balanced. Find a driveline shop and take the shafts there and have them rebalanced. Some machine shops may even have the ability to balance them.

+1 for W&F...

frout drive shafts have a little metal tag spot welded on them for balance these are prone to break off over time and will create a viberation take if off and go to a shop that do,s drive shafts and they can rebalance it for you

thanks for input.
