Vibration
Hello - I have a 2002 SD 4WD auto trans extended cab/short bed (92K miles). Run 55psi front and 70 psi rear per door placard. Recently started getting a vibration when cruising at 45MPH and to a lesser extent at 55MPH. I was due for new tires so I got Hercules which where balanced and also had the alignment checked (no problems.) Vibration has subsided greatly but still does it at 45MPH. A little faster or slower and it goes away. I checked the u-joints on the (one-piece) driveshaft and they seem tight. I do not feel any vibration in the steering wheel but really cannot tell if it is coming from the front or the rear. Any thoughts on possible gremlin would be appreciated

Im assuming you feel it in the seat? If so, its often towards the rear, feel it in the steering wheel its often towards the front. I have a vibration in the seat at 55-60, u-joints good, tires good. Im looking toward shocks(107k miles) on them, and servicing the rear end. Couple ideas for ya... Jay
