Carrier bearing

[dakota.morgan91]

I agree it will be accessible and relatively easy to change and on “other” trucks they may be fine but a Jeep truck in the rocks may be another concern .... and if they snap say goodbye to your drive shaft and what ever it slams into. I’m more worried about secondary damage after it detonates

All I can think of right now is the episode of Mythbusters where they tried to catapult a car by dropping the front of the driveshaft into a pothole while the car was in motion! Now picture a gladiator offroad catapulting over the rocks! xD

on a serious note as far as offroading that is a very good point and question. I bet they designed it with the torque of the upcoming diesel in mind (I hope), so I would assume it must be pretty hardy. Although (playing devils advocate slightly) I am curious if the Rubicon with the different transfer case uses the same unit? There is a chance the Rubi has a beefier shaft and carrier bearing and the diesel will be Rubi only... I really don't know, just speculating.

Wait, what exactly is the problem here? It won’t carry plywood?

you shut your mouth! lol

Well, on a serious note, this is the first I've heard that the Gladiator uses a carrier bearing and two-piece driveshaft. I hadn't thought about it before, and yes it does suck. Carrier bearings usually wear out long before U-joints or CV-joints do, and, it just creates another possibility of vibrations in the driveline by making the driveshaft unnecessarily complex. If full size, crew cab pickups can use a one-piece shaft, why can't a Jeep?

They likely did this to try and keep break-over angles intact. But personally I'd rather have a simpler design with a one-piece shaft and perhaps a brace or skid plate.

Funny Troll is Funny. Could you describe for the class exactly what a 'driveshaft brace or skid plate' would look like on a JT?

The next time we got someone at a show, they should bring some string with them - crawl under the rig & have someone hold one end at the t-case & the other at the pinion flange to see how much more clearance is created. If they had put a 1-pc driveshaft in it, we'd all be bitching about mangling the driveshaft on the rocks too easily. Toyota has used a center support for years & I've never heard of it being an issue.

Well, I could draw a picture if my son would let me borrow his crayons for a few minutes. But a brace or skid plate would look like a stamped piece of steel that would bolt onto both frame rails and run between the two so that the vehicle would high-center on the skid/brace before it would the driveshaft itself. Other vehicles have used similar setups for years. It's not rocket surgery. The amount of rear axle droop is controlled by the shocks, so it's not hard to calculate where to mount said bracing.

As far as Toyotas not having issues with their carrier bearings, that's likely because the rest of the truck either falls in half at the center of the frame first from all the rusting they do or the owner trades it in before it's out of warranty. The Toyota truck is one of the most commonly traded-in trucks in the nation at 1 year of ownership per the numbers.

Once a long wheelbase vehicle with a 2-piece driveshaft gets some mileage on it, that bearing is one of the most often replaced parts on the truck.

back in the day i had a bad carrier bearing in my 89 extended cab Toyota PU. Guess it's like anything else, if it breaks fix it

Not a big deal. Older BMWs had them too. Easy to tell when bad, and about an hour to swap.

Sounds like F.U.D. to me...

6800 miles. Chasing a driveline vibration. I dropped the rear driveshaft and test drove. Vibration gone. I too would prefer a solid shaft without the carrier bearing.

How did you test drive if you dropped the rear driveshaft? Front wheels only in 4H?

Did you end up getting a new driveshaft? OEM or single-piece?

There are several companies that provide drive shafts for the Gladiator. One of them is local. I've been debating going that route instead having the recall done to replace the shaft and bearing. I wonder if I could use the receipt for that to request Reimbursement for the cost of taking care of the recall myself?

my Jeep had the rear driveshaft recall also early production due to carrier Bering not greased the dealer kept saying they didn't have a replacement yet over a year may 14th so i went with a one piece Tom Woods, i've been trying to get some reimbursement but no luck yet.

Probably look like this:
