Mine was solved with a road-force balancing.

 

you were lucky, alot of people here tried it and saw no change, including myself. glad your nibble is gone though

 

Mine was solved by a careful Road Force Balance. Now, I will say that depending on the quality of the road, I will feel a little nimble. Nothing bad and definitely something I can live with as it passes. There is a stretch of interstate I go over going home and I get some nibble each time only on that specific section at any speed. I really think that if you can ensure that the wheels are good, the tires are good, and the balance job is good, and the steering wheel is not giving you a death wobble, then you are most likely feeling the road. The 2004+ F150 steering is very sensitive and accurate.

Incidentally, the nibble I had in the steering was caused by my back tires not being properly balanced. I didn't feel it in the "seat of my pants" as they say you will if the rear tires are out. I felt it in the steering. I don't have a lift, just a leveling kit, so I cannot put on a stabilizer w/out mods. I have just learned to live with the fact that certain roads aren't laid down as well as others and that I will have a bit of nibble on them. I say this because 99.99% of my driving the steering is just as it was when I had a stock setup..smooth and certain.

Good luck!!

 

I have tried it all and no help!!!!!

 

my local mechanic is going to print off the newest 5 page TSB for the steering nibble after hours today. He said it is a very extensive processto find the exact problem . When I get it I will try to scan it and post it here or somewhere anyway. I could email it to whoever would like to read it.

 

Posting it up here would be ideal.

 

I have read on this site that some of the mechanics performing the road force balancing aren't doing it right.

It worked for me. Good mechanic.

 

I agree. It's just as much the "balancer" as it is the equipment.

 

Nibble started with tire rotation at 5k, since then 1) road forced balance by tire store,nibble stopped 2) came back at 10k tire rotation 3) dealer road forced balanced, 5 new tires, new steering rack,seemed OK 4) tire rotation at 15k, front rotor seals leaking, new rotors (went bad from all the nibbling????) 5) now have slight steering wheel shimmy now and then, irregardless of the same road or tire
temp. At 10k after #3, Ford engineer & service manager took truck for ride , engineer said tire pressure was off.
06 F-150 XLT SCab 8' bed,HD payload, Tow Pkg 7 lug rims

 

Tire pressure was off? By how much, 15 pounds??? Wow.

 

Here's my fix: Get rid of the dang 20's. Get some 17s, 18s at largest. Buy some Michellin tires and RFB them. Fixed mine.

 

I never noticed any "nibble" I dont even know what a nibble is

 

You’re lucky, I had more than a nibble (steering wheel vibration) I had a steering wheel shake. The wheel would turn back and forth about a half inch or more when driving at 65 MPH or what ever the frequency was for your vehicle. My problem turned out to be the Baer Eradispeed front rotors, one of which was out of round by over .040 of an inch. They sent me new rotors and Baer considers them to be in tolerance at .015 inch out of round. It still has a slight nibble, but it is much better now. If only Baer could make round rotors I don't think it would be noticeable.

 

I am sure Ford knows how to fix this problem. They don't want to spend the money. I have seen a few people who get the to replace the steering rack and it has cured the nibble. Tire pressure being off a few pounds, tires being rotated, etc should NOT cause the steering wheel to wobble back and forth period.

 

I started a new thread asking about this exact problem before doing a search DOH

I got some new American Eagle 20" rims and Cooper H/T Discover plus 275/55 R20 Tires installed last week at a local tire shop on my 2004 F150 (New bodystyle). I noticed some considerable shake in the steering wheel in the speed range of 60-65mph. Took it back today, all 4 tires were balanced again and the same problem still exists. The ride is stiff in general, so every little bump probably makes it feel worse.

Never had any issues with nibble before the larger tires and rims. My stepdad is a mechanic, I'm going to let him take a drive and offer advice.
