ok i'm new to this diesel stuff but i'm learning ever so slowly. but i do i have a vibration in my truck. and i went underneath the truck to inspect to see and the only thing i've seen is oil coming from the rear end. mainly wear the drive shaft and rear end meet. and the only time i really get the vibration is when i start pushin the throttle but its still there when i get off of it too. so can some 1 help me figure this out because i dont want to take it somewhere and they do the same thing i did and they charge me a $100 than tell me to schedule a time to bring it in. thanks Ryan

 

how bad is it shakin? diesels naturally shake. get on a diesel tractor and start it. my tractor will shake ya up pretty good. shakes more at idle though

 

honestly my wife caught to it just before i did and she doesnt know jack nothing about diesels or truck in general. but its pretty bad. i feel it more in the steering wheel than in the seat

 

hmm i cant answer your question by much of a mechanical aspect but maybe check the bolts on your steering column. keep the hood open and see if you can see anything shakin. or maybe you got a cylinder or two not firing(injectors) but i'd think that'd be more of a v-8 problem. for now i'd say check the bolts and steering parts under the hood

 

rgr thanks ill do that tomorrow when i can

 

if that doesn't work i can't tell ya much more. i'm hopin one of the dodge guys will chime in here soon

 

Check Your U-Joints especially the ones In the front axel the stock ones are junk also if you have a 2 piece drive shaft check the bearing also the wheel bearings. Is it a auto or manual?

 

Sirwrenchiezolot is 100% right. Definately a good place to start would be your U joints in the rear shaft. Also check the carrier bearing if you have a long wheel base truck. Those things will cause a vibration under hard acceleration.

 

thanks guys but that was exactly it. the joint at the rear end shook pretty good and the front is not as bad im replacing both at the same time..
