Well, since the wheel shake isn't as exaggerated as it was prior to the road force balance, we decided it might be residual as the tires flat spots get some road time. The dealer was very cool in that they recognize it's still there. I'll report back after a couple hundred more miles to let everyone know what I find out.

 

Sounds great..... a few notes for troubleshooting if anyone is wise enough to turn this info into something.

1. It's definitely speed sensitive
2. Changing lanes makes a difference (wierd)
3. I have aftermarket rims/tires.... still have the problem
4. It reminds me of driving a forklift ... i.e. speed up/slow down reduces shake
5. This one is the most interesting to me. A rear balance issue you feel your butt shake. A front balance issue you feel the wheel shake. I've noticed that it almost seems to transfer from intensity from front to rear and back again. It's subtle but it happens. It makes me wonder if something causes the shake and then maybe harmonic balancing is also insufficient and allows it to move throught the truck.

Just my 2 cents.....and YES it is ANNOYING.

 

I've got 6200 miles on mine and it just started to shake like crazy this morning on the freeway for the first time. Went away at 60 mph came back at 65-80 mph...then went away completely! Came back about 5 miles further down the road and at all speeds over 60. Anyone found out any news yet?

 

Sound like a wheel balancing issue to me, my old Ford used to do that and I'd go get the wheels balanced and it would go away, as a matter of fact my old Ford has been doing it for a while now and pulling to the right, today I had new tires put in the front and now it rides smooth as silk (almost as good as my Dodge). I'd have to say thats pretty dang good for a truck with dang near 250K on the clock.

 

What model and year Ford?

 

I'm still searching for answers. I have to say I doubt it's the tires. My road force balance showed absoltely perfect on the printout. Yet now it happens much more frequently than it did before. I'm going to ask Chrysler to buy this back if that can't fix it. Absolutely love everything else about the truck, but you can't have the wheel shaking on all highway trips, just doesn't make sense.

The wheels could be bent (out-of-round) and balanced but still vibrate. Ask your mechanic to do a lateral and radial runout check on each wheel. This involves putting a dial indicator on the wheel while it rotates to measure any amount of wheel bend (runout). There is a spec, maybe 0.010" (ten thousandths) or so, which the runout must be less than. The same can be done for the hub (rotor flange) but a wheel will bend more easily than the hub.

 

This happened on my 06 and two brand new 09's (one I test drove and mine). I have a feeling it's something a bit deeper.

 

I had the run out checked on my latest visit. No help. MEchanic said runout was within tolerance. He also increased the tire pressure to 45psi. why this would help i have no idea. Did not help at all.

I have since switched to 17" rims with brand new Goodyear Wranglers (Silent armour). I ran these tires on my 2004 with no problems at all. The truck steering still vibrates. If anyone goes to the dealership and they tell you it's tire issue - Call BS!!! after the 10th wheel balance/alignment/rotation/runout check and brand new tires on steel rims - I think it's safe to say this is not a TIRE issue!!!
