Problem Description and Possible Solution
If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing differential clutch kit. An updated differential clutch kit available.

from stop to takeoff i get a clunk. it seems like there is a lot of slack in the drive train somewhere. it seems to be getting worse.any thoughts?
rumble noise at slow speeds turning or backing up and turning from the rear end shudders and shakes whole truck
I had the diff clutch replaced by Ford at 21000, 34000 and now at 77000. These are in kms so they work back to 13125 miles, 21,250 and 48,125 miles. It is a 2011 F150 XTR 4x4, 5.3l. I would like to know if there is something that I could be doing to extend the life of this part. Ford has been good at replaceing it without charge, but it is a real annoying problem.
Horrible grinding rubbing squeeking noise while making turns. But only happens after truck has been driven in heat on highways for long period of time.
Clutch pack is binding and slipping on corners and taking off from a stop
Rear makes a howling vibrating noise as it goes from. 30 mph on up. Have replaced the tires, but my mechanic suggested that it might be the differential. I have an appoint for him to check it out.
not fixed yet, After traveling 50 plus miles on interstate and you get off the interstate the rear end shutters at low speed, sometimes when you first take off it makes a little noise sort of like a bearing freezing up.
How much would it cost me to get a new rear axle completely done
Slight grinding sound coming from rear. Thought it was the wheel bearings.
Same as others, shudders when making turns . It's. Definitely the clutch packs.
new axel clutch pack was installed at 30k, now at 58k same pro blem.
Raced rear differential clutch pack
I had the this problem in may I had ford to fix it 480.00 was the cost and it never help it does the same thing took it back to for they told me we never had a truck in here like yours don't know how to fix it. I have a 2011 f-150 eco boost v6
61000, just out of warranty the again at 80000. Second time replacing the clutches in the differential. Ford covered the second time.
chattering noise when backing up or turning
Not fixed mechanic said clutch packs drained oil and replaced put in an additive helped a lot but getting worse again after a few months. makes whining noise when turning and has a shutter when starting off or backing up. Very disappointing Ford should recall and fix. Probably making noises long before detected just did not detect them until they got bad. Ford should fix very disapointing
Looking for a solution. I have seen from drive lines to rear end clutch, They replaced rear end clutch and same problem.
Hearing sounds when slowing down in rear end . Had fluid changed with no change to sound
grinding noise was heard from rear end when making turns under power. Replaced clutch pack and problem was solved....until one year later, same problem. Waiting now to see what ford dealer has to say.
I went to ford last week and they said that i needed to replace my ring and pinion gears in the rear. It would cost me $1800 to do that. I'm going to get an second opinion.
