It was about a day. I gave it to them over Thanksgiving so not real sure how long the repair took. I ended up driving with a mechanic and replicating the issue with him sitting in it with me. Then he knew right away the issue.

What was your mileage when you took it in and they covered it?

Did changing the fluid and adding the Friction Modifier help?I've researched this symptom on several Forums.
To start, I'm going to change the fluid in the rearend and add the required Friction Modifier for the limited-slip. I'll see what effect this has on the shudder.
Please post back what the dealer tells you on Monday.
Maybe between the two of us we can help determine what's going on
Thanks.

Sounds like they replaced the diff clutches under warranty.

Well after 3 weeks at the dealer they finally are saying they will go ahead and replace the steering gear. Ford finally gave them approval. I hope to have it back sometime next week and hope this solves this horrible steering defect.

Thank you all for posting all this information. I had the same symptoms at 71k. Shuddering while at low speeds both left and right. I went ahead and changed out the oil on the rear axle and used full synthetic and added a Ford XL-3 friction enhancer and after 100 miles the shuddering went away. Saved a trip to the dealer and a $190 service fee just to look at the truck.
Thanks to all on this thread!!!

Figured I'd join so I can help someone out. I have a 2006 espy that did the same thing. Spent almost $1000 on the front end replacing parts. Still did it. So I seen someone mention changing the rear diff fluid and adding the additive. Figured what the hell even though I was positive it was in the front. Changed it out and....bam! No more vibration when making slow turns giving it gas. Even seems to have freed up the backend some as well. Please try. It's worth the investment

If you have them, it’s the clutch packs in the rear diff. Had mine replaced and problem solved. Ford has new ones for the 15-17s that are upgraded carbon fiber. If you dont, check all vacuum lines, solenoid, and hoses running off the 4WD system that can be malfunctioning and causing your 4WD gears to slightly activate
