I am getting a strange rhythmic squealing sound from the right rear of my 02 F 350 that is going in time with the speed of the truck.
After the truck is run about 5 miles it starts;usually in cold weather but not always.
As the wheel speed increases the squealing sound pulses faster and as speed drops below 20 mph it stops.
Its definitely not brakes as I have accelerated and decelerated with my foot on the brakes and it has no effect on the sound.
I had this problem last year but before I could bring it in under warranty it stopped doing it.
I can't imagine that it is a wheel bearing problem, over the course of a year it should have seized by now.
I am starting to think u joints or rear diff.
Has anyone had a problem like this?
I still have 10,000 miles left on basic warranty and I think I am going to just have to take it in but I would sure rather know what the problem is before I turn it over to a hit or miss guessing game by Ford mechanics.
Any input will be appreciated.

I don't know much but it could be the carrier bearing on the drive shaft. Just a thought.

 

I have that on a couple of different trucks, one time was a hanger bearing the other time it was u-joints

 

I'm experiencing the exact same problem right now. Only difference is that I can't tell which side it's from. It didn't start until the temperature started dropping. but now I hear it even when it's back up in the 80s. Mine will also disapear above 50Mph. I found my differential oil to be real low. Hoping I had found the culprit I filled it to the plug hole level but it didn't effect the squeak.


rednekf350,
If you happen to come across an answer please pass it on. I'll do the same for you if I find it first.

 

rednekf350,
Put the SD up on stands today and took it up to about 45 MPH. The squealing started at about 15mph. It turns out that it is the Driveshaft Hanger Bearing. I went to the Ford parts counter (only place to get one) and it cost $134. The part is so rare that they had to order it from the plant in Kentucky, it will be here Tuesday.

One other thing. The Ford service rep became quite alarmed when I showed him the squeal. His first words were "Do not drive it any more ! " He said that when the bearing finally fails or seizes it will warp the driveshaft, burn up the Tranny, and kill the differential gears. Needless to say my SD is parked till Tuesday.


Just thought youd like to know.

 

I heard the bearing can get worn or damaged from having your spliines on your slip yoke binding. Did either of you experience a thud type "feeling" when you accelerated from a stop.

 

Nothing that I ever noticed.

 

To those who may have experienced the "thud" when starting from a dead stop, it probably is the slip-joint at the carrier bearing yoke. I took the metal clip off the rubber boot, packed the boot with lithium grease and placed two nylon ties around the rubber to seal it back, then massaged the rubber to force some grease into the splines. It works good. Have done it now every 30,000 miles. Takes a minute or two, but stops the "thud".

Well I just got back from a 500 mile roundtrip to Pa. deer camp and I didn't have any problems but the noise didn't go away either.
About 100 miles of the 500 was in 4wd and about 20 of that was in low range.
The noise sounds alot different in 4wd,more muted and the rhythm sounded slower regardless of speed. Go figure.
I am going to have that driveshaft bearing checked and hopefully replaced under warranty.
I really appreciate all the responses. That's what makes this site the best.

NOISE - DRIVESHAFT CENTER BEARING NOISE - VEHICLES BUILT AFTER 6/1/2002
DRIVESHAFT - DRIVESHAFT CENTER BEARING NOISE - VEHICLES BUILT AFTER 6/1/2002

Publication Date: October 17, 2003

FORD: 2002-2003 F SUPER DUTY


ISSUE:
Some 2002-2003 Super Duty F-Series vehicles built after 06/01/2002, with a multi-piece driveshaft may exhibit a squeaking and/or squealing noise from the center bearing while driving. This noise is produced when the bearing seal rotates in the bearing outer race.

ACTION:
To service, replace the center bearing. Use a center bearing assembly with a white paint dot (built after 6/9/2003). Determine the style of the driveshaft per (Figure 1) and (Figure 2), then follow the appropriate Service Procedure below.

SERVICE PROCEDURE
NOTE: WHENEVER DRIVESHAFT REMOVAL IS NECESSARY, IT IS IMPORTANT TO PAINT MARK THE DRIVESHAFT TO THE TRANSMISSION (OR TRANSFER CASE) AND THE REAR AXLE. ADDITIONALLY, MARK A PAINT LINE THE ENTIRE LENGTH OF THE MULTI-PIECE DRIVESHAFT ASSEMBLY. THIS IS ESSENTIAL TO INSURE THE DRIVESHAFTS ARE REASSEMBLED IN THE SAME ORIENTATION AS ORIGINAL. FAILURE TO REASSEMBLE THE DRIVESHAFT IN ITS ORIGINAL ORIENTATION MAY RESULT IN AN UNBALANCED DRIVESHAFT CONDITION.



PROCEDURE FOR DRIVESHAFTS ILLUSTRATED IN FIGURE 1
Remove the boot clamps from the rubber boot and discard.
Disassemble the driveshaft from the coupling shaft.
Remove and discard the retention slinger, center bearing assembly, and dust slinger from coupling shaft.
Install the new dust slinger and center bearing assembly per Ford Workshop Manual.
NOTE: DRIVESHAFTS OF THE TYPE SHOWN IN (FIGURE 1) REQUIRE THE INSTALLATION OF THE RETENTION SLINGER PROVIDED IN THE SERVICE KIT TO RETAIN THE CENTER BEARING TO THE COUPLING SHAFT.



Reassemble rubber boot and boot clamp to stub shaft and crimp the boot clamp.
Slide the other boot clamp onto the slip yoke of the driveshaft assembly, then assemble the driveshaft to the coupling shaft. BE SURE TO ALIGN THE PAINT LINE MARKS FOR PROPER ORIENTATION. Align the rubber boot with the slip yoke boot groove. Clamp boot clamp while the boot is in the relaxed position.
Reinstall the driveshaft assembly to the vehicle per the Ford Workshop Manual.
Drive the vehicle 10 miles at different speeds with the driver's side window down to verify that the noise condition is corrected.
PROCEDURE FOR DRIVESHAFTS ILLUSTRATED IN FIGURE 2
Remove and discard bearing strap bolts and remove and discard bearing straps.
Remove and discard the end yoke retaining nut.
Remove end yoke from the coupling shaft assembly. BE SURE THE END YOKE IS PAINT MARKED FOR PROPER REINSTALLATION.
Inspect end yoke for any damage to lug ears and/or hub splines. Save the end yoke for reuse.
Remove and discard both the center bearing assembly and dust slinger.
Install the new dust slinger and center bearing assembly per Ford Workshop Manual.
Reassemble the end yoke to the splined shaft. BE SURE TO ALIGN THE PAINT LINE MARKS FOR PROPER ORIENTATION.
Install the new End Yoke Nut (F81Z-4819-AA) and torque to 407 N-m (300 lb-ft).
Install the driveshaft assembly to the coupling shaft connecting the u-joint to the end yoke. THIS WILL TYPICALLY BE A TIGHT FIT AND MAY REQUIRE SOME EFFORT TO SEAT THE U-JOINT INTO THE END YOKE. BE SURE THE PAINT-LINE BETWEEN THE TWO SHAFTS ALIGN WITH EACH OTHER.
Secure the U-joint to the yoke using the bearing straps and bearing strap bolts:
For F250/350 applications use Bearing Strap (E4HZ-4A254-B) and Torque Fasteners (F81Z-4N272-AA) to 34-41 N-m (25-30 lb-ft).
For F450/550 applications use Bearing Strap (E4HZ-4A254-A) and Torque Fasteners (F1HZ-4N272-A) to 61-81 N-m (45-60 lb-ft).
Reinstall the driveshaft assembly per the Ford Workshop Manual.
Drive the vehicle 10 miles at different speeds with the driver's side window down and verify the noise condition is corrected.

i can get the figures 1 and 2 if you need them...

 

emtabmm,

I was wondering if this is realitivly common occurance for these newer trucks. I've spoken with 3 different ford service departments and all gave me roughly the same answer, "1 or two occurances in 15 years" The bearing is currently being replaced on my SD. They had to go all the way to the Kentucky plant to get the part. It must be a reacurring complaint for them to generate a detailed "fix" on the Tech manual. Have you see many of these bearing issues?

P.S. The Ford mechanic was totally surprised when I show him the article you posted

 

It figures the techs wont use the resources given to them....As far as common, I've seen 4 here in southern In. at my Dealer.

 

I am scheduled to take mine in on 12-13.
I told the service writer I was bringing in the tech bulletin and she said "great".
My friend is a tech at the dealer and I am trying to arrange for him to work on it. I also want him to make sure they have the part available before I take it in so I don't lose more than 1 day.

 

I know of a PSD owner who had a one piece driveshaft custom made and eliminated the carrier .

Make sense?
