Hi bowhuntrr, if you ever find out what the problem is please let me know, I have a similar problem. After I had my wheels balanced it was gone for a week but now it's back again.

ive got a 2002 ext cab and it had that vibration with the stock wheels and i bought new wheels and it still has is. i dont know what it is, ive check bolts and joints and bushing and i see nothing that is bad. its kinda annoying but ive learned to live with it.

I found this link in the forum about the front drive shaft spinning in 2wd on trucks with autotrac and that the spinning is normal.This would explain the vibration.I am also getting a slight vibration.Maybe I'll change out the U-Joints with greaseable joints.

I am printing this thread off for the dealership. I have had three balances, two rotations, 2 alignments. The vibration leaves only for a short time and it comes back.

Mine is between 57-63mph

I saw a sign in one of the local AutoZone's that said about cv joints, how to tell if they're worn. 1, vibration at high speed 2, popping at low speed turning. I wonder if this could be it, my truck has 106K miles on it. I had the front wheels balanced and the vibration was almost gone for about a week. I wonder if a balancing cancels out the vibration of the cv joints until it gets too much ? Just a thought. The cv joints are those the complete "half shafts" that go from the transfer case to the front wheels ? Also, all people who have this problem all drive 4WD ?

I've got the same problem.........I recently replaced my inner and outer tie rods with some Dana ones......then I had it aligned and it still does it.....I'm kinda leaning towards the CV's being shot......anybody know how to tell if those are bad??

[bowhuntrr]

thanks for the info, i guess i should have stated my trucks are only 2 wheel drive.

I had a customer suggest the flex-plate my be out of balance. any of you have that checked? and how would you do that?

What is this flex-plate and where is it located ? Mine is a 4WD truck.
It seems when the truck is loaded it almost disappears.

He is probably talking about the plate that connects the crank to the stall convertor. It is a plate. If that were the cause you would see the vibration at the same exact rpm's in any gear not just a speed. IS that what you see?

No, it's only between 'bout 50 and 65 mph, either in 3rd or OD.

How about getting the driveshaft balanced, or at least checking the balance?
