Does a center support (carrier bearing for a 2004 f-150 make a noise when wearing out

I'm guessing your you are referring to the drive shaft center support bearing. Remove u-joint 4 bolts at rear diff., then 2 bolts for center support. Slide driveshaft assembly out of trans. and lay on ground. On either side of the center support, make alignment marks on front and rear half of drive shafts with a crayon or tape (very important for re-assembly). Slide rear half off. Press out center support. Clean sleeve with emery cloth or 400 grit sand paper. Press on new center support, lube splines and reconnect drive shaft halves making sure alignment marks meet. Install assembly and torque bolts.

Provided that this is a rear-wheel drive vehicle, there are a number of things which can make noise when you accelerate. Most are due to excess clearance in moving parts. This means some parts are worn out.

On the outside, the U-joint next to the rear differential can be worn and make noise. Inside the differential, usually a pinion bearing(carrier bearing) can make a noise like a whine or growl depending on the gap.

Now in the axle tube, the axle shafts have a bearing on each wheel. Like any bearing, when they wear out, noise usually indicates failure.

When Torque is applied on acceleration, the parts shift creating noise. If you have a Limited Slip Differential, there are clutch plates which have a material which can wear out. These types of rear ends also need a special Additive to make the parts work. Sometimes you get a clatter when the additive is low.

Have the U-joint checked first as it is the only external part to check. The rest will need disassembly.

Please rate my info.

1. Remove the transmission or transaxle as outlined.
2. Insert a pilot shaft or an old input shaft into the center of the clutch disc, pressure plate, and the pilot bearing in the crankshaft.
3. With the pilot tool supporting the clutch disc, loosen the pressure plate bolts gradually and in a crisscross pattern.
4. Remove the pressure plate and clutch disc.
5. Clean the transmission and clutch housing. Clean the flywheel surface with a non-oil based solvent. Wash your hands before installing or handling the clutch assembly parts. Hold the clutch disc by the center hub only.

Before assembly, slide the clutch disc up and down on the transmission input shaft to check for any binding. Remove any rough spots with crocus cloth and then lightly coat the shaft with Lubriplate.

1. To remove the throwout bearing assembly: Remove the return clip and take out the throwout bearing carrier and the bearing.
2. To replace the throwout arm use a / 16 in. punch, knock out the throwout shaft spring pin and remove the shaft, springs, and the center lever.
3. Do not immerse the throwout bearing in solvent; it is permanently lubricated. Blow and wipe it clean. Check the bearing for wear, deterioration, or burning. Replace the bearing if there is any question about its condition.
4. Check the shafts, lever, and springs for wear and defects. Replace them if necessary.
5. If you hadn't planned on replacing the clutch disc, examine it for the following before reusing it. Loose rivets. Burned facing. Oil or grease on the facing. Less than 0.3mm left between the rivet head and the top of the facing.
6. Check the pressure plate and replace it if any of the following conditions exist: Scored or excessively worn. Bent or distorted diaphragm spring. Loose rivets.
7. Insert the control lever into the clutch housing. Install the two return springs and the throwout shaft.
8. Lock the shift lever to the shaft with the spring pin.
9. Fill the shaft oil seal with multipurpose grease.
10. Install the throwout bearing carrier and the bearing. Install the return clip.
11. Grease the carrier groove and inner surface.
12. Lightly grease the clutch disc splines.

The clutch is installed with the larger boss facing the transmission.

1. Support the clutch disc and pressure plate with the pilot tool.
2. Turn the pressure plate so that its balance mark aligns with the notch in the flywheel.
3. Install the pressure plate-to-flywheel bolts head-tight. Using a torque wrench and, working in a crisscross pattern, tighten the bolts to 11-15 ft. lbs.
4. Install the transmission or transaxle as outlined.
5. Adjust the clutch as described in the following information.

If the noise is constant then it is most likely a bad axle bearing or side bearing on the carrier.The dana44 differential is known for wearing side bearings.If the noise pitch changes with aceleration and deceleration then it is a bad pinion bearing.I would be prepared to replace all 6 bearings even if they appear good because of the age and they are prone to failure.Need to get the problem addressed before the ring and pinion gears are damaged.

checking the bearings is a great place to start. to take the axles out you will need to remove the tires and axle cover in side there is a center pin with a single bolt holding it in. remove the bolt and gently pull the pin out DO NOT ROTATE THE AXLES after you remove the pin this will cause the spider gears to fall out of place. once you have the pin out push the axle in towards the ring and pinion and ther will be a c clip to pull out i use a magnet. installation is just in reverse just be careful not to turn the axle sometimes lining the spider gears back up can be a pain. hope this helps

Pretty easy! Here are the steps:

Removal & Installation

1. Remove 2 center bearing retaining bolts and remove the center bearing and driveshaft assembly.
   
2. Check the center bearing for wear or rough action by rotating the inner race while holding the outer race. If wear or roughness is evident, replace the center bearing assembly. Examine the rubber cushion for evidence of hardening, cracking, or deterioration. Replace as required.
   

To install:

1. Place the bearing in the rubber support and the rubber support in the universal shaped support, if removed.
   
2. Install the center bearing and drive shaft assembly. While supporting the center bearing in position, install 2 retaining bolts and tighten to 39-53 ft. lbs. (53-72 Nm).
   
3. Road test the vehicle and check for proper operation.

This is due to internal wear in the differential and should be looked at by a technician you trust before it gets too bad and leaves you stranded.

well uneven wear is not the bearings ,the main cause is worn shock absorbers ,wheel bearings will just make a noise

noise producers on vehicles include the worn brake pad indicator that rubs on the disc when the pads are dangerously low , loose seal shields on the diff pinions , tail shaft noise from failing bearings , "U" joints , center bearing supports and shields for that bearing touching the support bracket from failed bearing rubber mount
if is only heard when moving ,what I am suggesting that everything that turns has to be carefully inspected
for example a bit of rock stuck between the diff flange seal shield and the diff housing will create a noise that is amplified by the tail shaft
