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?
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.
rumble noise at slow speeds turning or backing up and turning from the rear end shudders and shakes whole truck
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.
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.
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
Raced rear differential clutch pack
Slight grinding sound coming from rear. Thought it was the wheel bearings.
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
Noise at 70 miles per hour
having a vibration on take off, was told it needs rear differential clutch pack kit. was quoted a price of 700 for parts and 900 labor!
How much would it cost me to get a new rear axle completely done
Rear end grinding noise and sticking/grabbing when cornering. Spoke to a recently retired ford mechanic who said it was the clutch pack in the rear end and that by making a couple tight circles on a dry surface both ways would help to free the clutch which does work most of the time. Truck now has 48,000. I also changed out the fluid to amsoil and added an extra quart. Clutch still sticks and I will have to replace it sooner than later.
Noise coming from rear end turn slips
Front end grinds around turns and when heavy braking is applied, need to drive with traction control off for it to go away
