Check the u-joints in the drive shaft. Are they binding up? Work the u-joints around by hand with the driveshaft out. They should turn smoothly and uniformly-any looseness or stiffness in any portion of travel is a bad u-joint. Not sure if u-joints on Nissans can be replaced, or if you have to buy a new or used driveshaft with the u-joints. At one time u-joints were not replaceable, but some aftermarket suppliers were trying to change that. You would have to check at a parts store.
Check the frame piece that the carrier bearing and bracket sits on. Is it still straight and true? Not bent from being hit from underneath (like running over a large boulder)?
Is the bearing still good? What is getting busted, the bearing itself, or the rubber insulator ring, or the metal bracket that holds it all in place? Unless there is a problem in the rear differential (like locking up), it is likely a mis-alignment of the bracket or frame it sits on, or a seriously bad u-joint, or a seriously bent drive shaft.

1996 Dodge Dakota SLT ext cab 3.9 V6. How to remove drive shaft? Has a double shaft with a bearing in the middle. Bearing has a square frame around it.Has 3 u-joints on the drive shaft.

The shaft is removed in one piece. You first locate the two bolts that hold the center bearing assembly to its cross brace and remove them. Then, you go to the rear differential and remove the two straps holding the rear u-joint to the pinion shaft. Once you remove the rear u-joint from the pinion shaft, tape the loose end caps in place to prevent loss. Now you can slide the driveshaft to the rear, disengaging it from the transmission in front. You may want two people to do this as you need to avoid allowing the front yoke of the driveshaft to slam into the ground. Installation is the inverse of removal.

did you mark the two ends of the shaft at gearbox and diff
so they lined up again
with the center bearing replacement
did you mark the two halves before separating and replacing the center bearing
then make sure they lined up again

if vibration is there
you may need to go to a diff shop and have the drive shaft balanced properly

This may depend on which side of the support bearing the slip joint is on the tail shaft. If it is on the diff side of the bearing then the problem will be that the slip joint has seized and every time the diff rises or falls from load or bumps in the road instead of slipping it pushes the whole shaft forward or pulls back to allow for the changed length of the distance from diff pinion and rear of gear box. If the slip joint is in the rear of the gear box then you may have to alter the angle that the mount has to the drive shaft. On a Mazda I had I found that the mounting plate was square to the chassis but the bearing needed to be about 3 degrees off to compensate for the drive shaft angle. This meant that the ball bearing was under mis-aligned load from the hard rubber and caused premature wear of the bearing

460 with a C6 trans & a 8.8 rear end how long of drive shaft do I need center to center of front & back Ujoint

This isn't something that should be advised on line.

You might need a 2 piece drive shaft with a carrier bearing, or a single piece might work.

You'll need to take into consideration the length of the spline (either @ the tail shaft of the transmission or @ the carrier bearing) to make sure there is sufficient spline length to allow for the lengthening and shortening of the overall length as the rear axle moves up and down with the increase or decrease in spring loading. Also need to be aware (on a vertical plane) of the relative parallelism of the transmission output shaft and the differential input shaft.

This one can bite you big time if you don't do all your homework!

In any event, you'll probably be better of if you engage the services of a professional drive line shop in your area.

Good luck!

Viberation in drive line truck has 7 u joints, replaced the 2 rear ones,vibe still there,but somewhat better. the rest of the seem to be ok is there a different shaft that would fit? at $50.00 a joint it...

Did you change the carrier bearing. It will be cheap compared to a transmission and new drive shaft. Got 1 in my shop right now. Customer did not listen. Check that carrier bearing Cost $1350vs $50

On vehicles covered by this information that are equipped with a two-piece rear driveshaft assembly, the center support bearing may be removed for replacement. To be sure if your driveshaft may be serviced, check with your local parts supplier or dealer for parts availability information.
  1. Matchmark and remove the rear driveshaft assembly. For details, please refer to the procedure located earlier in this section.
  2. Remove the strap retaining the rubber cushion from the bearing support.
  3. Pull the support bracket from the rubber cushion and the cushion from the bearing.
  4. Press the bearing assembly from the halfshaft.

To install:
  1. Assemble the center support bearing to the driveshaft:
    1. If removed, install the inner deflector onto the front shaft half and ***** punch the deflector at 2 opposite points to make sure it is tight on the shaft.
    2. Fill the space between the inner dust shield and bearing with lithium soap grease.
    3. Start the bearing and slinger assembly straight onto the shaft journal. Support the shaft and using a length of pipe over the splined end of the shaft, press the bearing and inner slinger against the shoulder of the front shaft half.
    4. Install the bearing retainer, the rubber cushion onto bearing, the bracket onto the cushion and the retaining strap.

  2. Align and install the driveshaft assembly to the vehicle.
