I know, I know I am driving ya'll nuts, but this problem WILL NOT GO AWAY IT SEEMS and I am at my wits end. If I cant cure it I am gonna sell the truck.

Ok I fixed my brakes, they work great I got new drums and new shoes and took back the shoes I got at napa which sucked.

Now onto my vibration:
At take off you feel what I can only describe as perhaps a stutter. When you take off it almost feels as if something is wiggling. The t-case lever actually wiggles side to side during this takeoff and seems to move alot more than I would expect. At higher (btwen 35-50+) speed there is a slight vibe, no stutter/wiggle but the vibe remains. It happens under moderate acceleration, coasting or light acceleration and you cant feel it at all.

I have:
-Had it to a driveshaft shop where they apparently replaced some kinda stud, and balanced my driveshaft and replaced the carrier bearing.

-I had the guys at my shop check all the mounts. The motor mounts seem fine, the tranny mount had some play but very little. Transfer case looked as if it may have touched the underside of the cab body, slight rub mark there-perhaps with torque it rubs..i dunnno.

-When changing gears it clunks into gear in R or D. I was assured my U-joints are fine, but I am thinking the clunking means they arent. The driveshaft guy said he woulda replaced them otherwise.

-Last thing is the shifter linkage will not work properly. You must jamb it into park and even then if your on an incline the truck rolls slightly and it locks into park. I have adjusted it 2x now and for awhile its fine, then it gets sloppy again. Thinking its related to the u joints too.

So I have a tranny mount coming monday and gonna try that, if that dont work I am gonna do u-joints. I cannot think of anything and I mean anything else possible that could cause this besides perhaps I damaged something while 4 wheeling and having no other t100 to compare it to on hand I cant narrow something like that down.

Like I said, if it cant be cured its a money pit and I think ill go buy an F250.
