2004-2008 F150 vibration issue.

[sspstang]

For about 42k miles now, my truck has this vibration in the wheel, at 60-65 mph. I have had 3 different sets of wheels on it, and I have taken it to countless tire places, including discount tire. I had the tie rods replaced at 140k. It gets really annoying, because I drive a lot, and I can not figure it out. The current set up, is 20" Mamba rims, with pirelli scorpions 275/60/20s. I also had these tires on the truck when I was still running the stock wheels. I swapped over to a set of 22" rims, and they had goodyear 305/40/22, and it was doing the same thing. All three sets of wheels and tires have left the vibration at the same speed, which makes me think, it isn't the tires or rims. Has any one ran into this? It goes away at exactly 66 mph.

It sounds like driveline harmonics to me. Have you checked the pinion nut to make sure that it is tight? You might consider having the driveshaft checked for straightness & balance.

A co-worker had been complaining about similar vibrations for a while in his F150. His pinion nut had backed out - completely stock truck with rearend never touched. He had it retightened and no more vibration.

Ford has had an issue with these trucks having a vibration. Just curious, 4 door?

There is a TSB concerning it. Basically road test with a vibration analyzer to find the frequency and go from there. Tires/ driveline have different frequency they vibrate at.

Yea I think they even added a weight to the exhaust on some of those trucks because the exhaust system had a vibration.

Will do. That makes a little more sense.

Yes it is a 4 door.

mine does it too!

You say the vibration is in the wheel.... I am going to assume you mean the steering wheel.

These trucks are VERY sensitive to tire balance issues. Ford actually says have the tires road force balanced and it should be less than 25lbs of road force, but they actually want less than 10 which is tough to do even for a new tire. I have seen many trucks with over 50lbs of road force on the tires!

The larger/aftermarket wheels and tires make it even worse usually.

The first step in the TSB is basically to do a proper road force balance. (after getting proper NVH Hz reading.

General rule of thumb is if you feel the vibration in the wheel, its wheels/tires type of thing, feel it in your butt, its driveline/dampner time.

I ask about the 4-door thing only because it seems all the worst ones I tried to fix were 4-door crewcabs with short beds.

The real question is, does the seat squeak?

Yes I meant in the steering wheel. It is only shakes my arm. I will do this, I am so sick of it.

Only if I fart.

I stopped in at my tire shop, that I take all of my vehicles too. The owner who has a 07+ crew cab silverado, told me, that when he put his 24" wheels on his truck, he to picked up the vibration. He was saying I needed some sort of round ring that would take up the space on the hub. He says that is more then likely where it is coming from, as he checked the balance again, and they were perfect. Has anyone heard of this ring? He said it was 40.00 for all 4. I would be willing to take a shot, if it would fix it.

Hub centric rings, certainly necessary if your wheels r not snug around the hub now. Those fords came with hub centric wheels from the factory most aftermarket r lug centric, the centering rings take up the space between the aftermarket wheels so it's mated to the hub again.

this....spot on. And if a pinion nut IS loose, expect to rebuild the unit soon
