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
How much would it cost me to get a new rear axle completely done
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.
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.
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
new axel clutch pack was installed at 30k, now at 58k same pro blem.
61000, just out of warranty the again at 80000. Second time replacing the clutches in the differential. Ford covered the second time.
After several months of road dirt road travel to a job site, my F-150 started to make a grinding noise. When I noticed the problem i was 150m away from home and had to drive back. Keeping it under 55mph i was able to limp home. The Ford dealership mechanics knew the issue as soon as I described it and corrected it with new rear gears. That's one of my problems solved.
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
chattering noise when backing up or turning
kept hearing grinding noise in rearend noticed wheel seals leaking when chanig back brakes took to garage to get them replaced when i went to pick up was told rear gears where chewed up but it was already back together so i had to get someone elseto fix gears and it took a week + cause couldnt find gears
Grind or shutter when starting out or on turns in rear end
I have that chatter problem in the rear end that people were talking about. When I turn corners at low speeds it feels like I'm in 4x4 or going over a rumble bar..... had the dealership check it out and they said it was the rear differential rear crutches. Told me with parts and labor looking at $800...... any help or advice would be much appreciated.
