I have a 08 2500 6.7 h&s tuner,egr,dpf delete,cat back 4",6"lift & s&b intake.Recently i have been getting a weird rumbling noise which sounds like it is coming from the front end.I have changed the oil in the tc & both diff,s,replaced the front u-joints & had all the wheels balanced with no look.Can i remove the front drive shaft and drive like that to try to eliminate the shaft.Any thoughts.

 

Wheel bearing?
