Engine/Transmission (1994 - 1998) 98 2500 diesel hard vibration

[Birchman]

Hey,need some ideas/help 98 2500 diesel not so bad when whole vehicle is cold but once driven and warmed up I have a hard vibration/rubbing underneath especially turning too the left you can feel it through the seats,starting to think it's more to the middle to back of truck.seems to be getting worse.

Thanks the Birchman

You'll probably find the propellor shaft center support bearing is shot.

Definitely check the carrier bearing.

Another thing you can check is ff it has a 4" or larger exhaust on it, check to see if it's hitting the frame. I've seen self-installed systems where fellows don't put all the brackets on and the pipe will shift at the turbo allowing the larger pipe to hit the frame. Makes an awful racket and you can feel it in the floor, especially on the passenger side.

Thanks a lot!!!when I get home I'll check it out.

Thanks I'll check it out just had new exhaust put in but this problem has started before that
