JXB Performance Driveshaft Center Carrier Bearing Support

I took the plunge and got in on the preorder for the JXB Performance 2-piece driveshaft carrier bearing support. The parts that arrived were top-notch quality with great fit and finish. I went ahead and ordered the carrier bearing spacer drop kit as well, but didn’t end up needing them with the +1 Coachbuilder shackles and RAS.

Install consisted of using a sawzall to cut through the OEM carrier bearing casing - a little nerve racking but worth it in the end. Use a utility knife to remove the remaining rubber bushing and then install the included 2-piece bushings and carrier housing. I went ahead and added some blue loctite for peace of mind.

Just a couple things to note:
My OEM carrier bearing is about 9 years old with 155K miles. That said, it wasn’t in horrible condition - though, it did have some slop in the driveshaft, and you could feel it going from reverse to drive, as well as from coasting to on the throttle. The JXB bushing removed all of that. Power delivery and shifts are as smooth as can be with the Road bushings I went with. I don’t feel any slop in power delivery anymore, and there’s no more hesitation between on and off throttle.

Is it for everyone? Probably not, but it’s worth it for trucks with higher mileage or probably for those chasing high power with headers or boost. I have no regrets with the install and would recommend this product for those interested.

 

Looks like a great kit! It's made it to my list of "soon!" Thanks for sharing the experience! Was there a shop you ordered this thru on a GB?

 

Just ordered mine!!!!

How did it feel on road during hard acceleration?
Any noise or vibrations?

 

I ordered through their website on preorder

 

Feels fantastic on hard acceleration, absolutely no hesitation. It’s smooth, no vibration at all. I went with the road bushings

 

Looks like you kept the OEM bearing? And how much play did you have in the stock bushing?

 

Other options out there that don’t use a factory bearing. Which is what I got. https://slewhousemotorsport.com/products/toyota-billet-adjustable-center-support-bearing

 

The slewhouse option is about $100 cheaper since it comes with the bearing already.

 

Yeah, I kept the OEM bearing. It’s a sealed unit, and I didn’t see any issues with it. I had maybe 1/4” of movement each way I pushed it

 

I think mine also moves almost 1/4” each way. Were you experiencing any vibrations?

 

I didn’t have any complaints with mine. I figured it was getting up there with wear/tear, and was itching for an upgrade

 

Can someone help me
I am trying to install this and the holes dont line up
I have a 2016 tundra

 

Sorry, I didn’t have that issue. Is the bushing centered around the bearing?

 

Yes

I have tried flipping it around to see if that would work and still no. What's wierd is that the install video on YouTube from jxb is on a

$29 2014-2021 tundra Driver Side (Chrome-Left)

2014-2021 tundra and your is a 2016. But my driveshaft looks different from yalls ?!

 

Any rear lift at all? And are you RWD by chance?

 

Yes I have a baby lift of 1.75 in the rear
And it's 2wd

 

Is yours 4wd?

 

Mine is 4WD. 2WD has a slip yoke going into the rear of the transmission. May possibly need a drop spacer or something if you have that much rear lift

 

Okay so after reading the reviews on this I decided to go for it. Seemed like a straight forward install, everything lined up nicely and loved the way it made the truck feel on acceleration. Drove it to head out with some friends tonight and about 20 min in I started to hear a whirling noise followed by a burning rubber smell. Luckily I was just arriving to my destination at that time and I hopped under the truck to look and everything looked okay. Babied it on the way home and no sound or burning smell but I know it will return if I get on it a bit. I'm thinking something was heating up excessively causing the issue. Not sure if its the bearing itself or what. I'm going to take it apart tomorrow and have a look. Has anyone else experienced this or have any ideas what it could be? I did email jxb and they are trying to help trouble shoot as well.

 

I’ve got about 3K miles on mine since install, but I haven’t had any issues with noise, vibration, or burning smell.

 

So I found the culprit. Must have just been off a bit but the rubber bushing was catching the rear driveshaft shield. There’s certainly not much tolerance on the back side of the bushing. It looked clear from below but was catching at the top. Took everything off and just adjusted the position slightly and it seems all good. I will say, JXB was very responsive to my emails as well. Jay seems like a good dude.

 

So i got the redesign of the carrier bearing from jxb for my truck.

I am lifted in the rear about 2 inch. I measured the angle of the drive shaft and this is what I got.
I drove it around for a couple of days and didn't feel any vibration(I think, I dont know where I am supposed to feel the vibration).
Question is do I need a carrier bearing spacer?

 

I don’t know about the angles. There are probably others on here that will know much more about that. My understanding though is that if you don’t have a vibration from take off say 0-15mph you are good and don’t need a drop kit. You’ll feel a driveline vibration, it’s not super dramatic but definitely something you would notice.
