Center carrier bearing.

Need some help please.

I started to get a vibration under the truck a few weeks ago. I read on here somewhere talk about the center carrier bearing. I spun my center bearing around 180 and it made a huge difference. I want to replace the carrier bearing and wanted to know if anyone here has done it before? It looks like I may need to remove the U joint maybe?

Any suggestions would be appreciated..

First, you'll need to mark up the drive shaft with a paint pen at all the disassembly points. Mark the rear diff to shaft flange, slip yoke, at the u joint you disassemble, at the carrier bearing, and at the transmission to shaft flange. You are doing this so that when you re assemble the shaft, you assemble it exactly as it was before to maintain it's balance. I found it was easier for me to remove the entire drive shaft and take it to a bench vise to remove the u joint. I tried to remove the u joint with my big c clamp under the truck, but it was pressed in too good for the c clamp to handle. Once you get the u joint out, there is a staked nut on the shaft holding the CB in place along with a few washers. I would recommend getting new nut and washers to go with your new CB. After you get the stake nut off, you'll have to figure out how you want to remove the CB. I had a shop press at my disposal, so I used that. You may be able to rent a 2 jaw puller from the parts store, or slide hammer, or just use a BFH. How ever you do it, be careful not to damage your drive shaft. Once you get the old CB off, grease up the new one and slide it on as far as you can get it, with all the hardware it needs. You might not be able to slide it on completely, so at this point is where I used a long socket and a hammer, and I tapped it on enough to where I could assemble it the rest of the way and thread the stake nut on. There are 2 torque specs for the stake nut. One is high to ensure that the CB is seated all the way, then you back the nut off, and put the lower, final torque on, then you stake the lip of the nut on to the notch in the shaft. I'm not sure what the Torque spec is off hand, but I'm sure you could pry that info out of the internet somewhere. The rest is reverse of disassembly. While you're there, you might as well grease the hell out your slip yoke. One person has even gone as far as drilling and tapping in a grease fitting for the slip yoke. Hope this helps some. Good luck

 

Thanks for the write up it will help. I plan on doing it either this weekend or the one after. I will let you know how it went.

 

Some quick points about my experience. I used a

$54 Sunex 52BS Bearing Splitter, for Shop Press

Sunex 52BS bearing splitter to, first, remove the yoke from the splined shaft, then, the bearing. I used a 20-ton shop press. They came off easy. If you don't have a press, you may be able to use a malley/hammer to strike the splitter. I used a punch, I think 3/16" to install the bearing. Tap it in place gently; you will feel when it seats. I used the press and bearing splitter to install the yoke far down enough until I could install the nut. I used a weld seam on the driveshaft to hold the splitter.

I re-used the staked nut; used blue threadlocker during the install. Could not torque the nut because the shaft kept spinning in my little 4" vise. Used an impact driver to install the nut.

I lost all my marks when I cleaned the driveshaft. But, after a week, I have not yet experienced any vibrations. Didn't have any before. I replaced the u-joints and carrier bearing on a 07 Taco 4-door, 4X4 long bed with 124K miles.

Hope this helps someone.

 

I just replaced mine. I didn't do two torques on the nut and my lines didn't line up. I installed the yoke then the 2 bolts that hold the carrier bearing up then when it came to the diff, the bolts didn't line up. They were just a little off so I jacked the rear up and let the tires spin until the bolts lined up. Is that a big Nono? If so, why?

 

Anyone know?

 

That is why it is better to use a center punch to mark the match marks. You cannot wash them off.

 

No big deal

 

I put everything back together and took it for a short drive. Haven't noticed anything so far.

 

Replaced my carrier bearing (

$57 Dorman 934-401 Drive Shaft Center Support Bearing Compatible with Select Toyota Models

Dorman 934-401) a second time, and replaced the center u-joint, since I had to remove it to remove the yolk. Bearing lasted 2 years, but I realized I installed the bearing 180 degrees off last time That raised the shaft about an inch or so and probably put extra pressure on the rubber, which probably accelerated wear. Replaced with APDTY 045512 which came in a bag labelled MTC 9283. Replaced ujoint with a Moog 254 which was a tight fit at the ends when trying to fit the lock ring. The ujoint does feel and look like a heavy duty design, but if I get it again, I will grind the ujoint caps half a mm. Or stick with

Some notes to self: torque for the 8 bolts/nuts: 65 ft/lbs; 2 bolts on center carrier: 27 ft/lbs; yolk staked bolt: 51 ft/lbs. OEM carrier bearing pt#s:

Just in case anyone was wondering still.... The center support nut is torqued to 134 ft-lbs to make sure the CB is properly seated. Then back the nut off and torque a 2nd time to 51 ft-lbs. Hope this helps someone out!

Also, can anyone help me out?! I have a 2009 Prerunner 2WD TRD Sport DC Long Bed.....I know my driveshaft is slightly different than the 4X4 Tacos. My slip yoke slides into the output shaft of my transmission. I believe, the slip yoke is lubed by transmission fluid. Should I also be greasing the splines of the slip yoke every so often with bearing grease?? Just worried that some would end up in the transmission? Thanks for the help!

 

No, You do not need to grease the splines going into the transmission tail shaft.
