My truck in my signature has a random vibration that has been popping up the last couple months. It will slowly come up to a moderate vibration and then slowly go away over a course of 2-3 miles. A couple months ago it did this a few times and have not had this happen since then until yesterday. It feels like going down a washboard road except not as severe and totally random as to when it will show up and not something I can get it to do. Tires appear fine and are rotated every oil change. It's not the roads as I travel these roads all the time and would know. Only thing I can think of is something is loose or some slop has built up somewhere.I mention to my local mechanic when I had my wife's car in for service and he was a little stumped although he hasn't looked at it yet. Any thoughts? Dan

Have you been able to isolate it to a general area? Front/back, left/right. Can you feel it or just hear it?

Check the steering box to frame bolts for tightness as well as the Pittman Arm to tie rod joints. Manufacturers like to use no grease plastic insert joints that don't last very long and being a Michigander myself, I know what the roads here are like....bad to worse. Government Motors has had some ongoing issues with the steering box itself on pickup trucks, yours may be one with the issue. You need to check the TSB's to find out.

whats the tsb numer so i can see if my truck needs repaired ? ..
