Unserviceable main shaft u-joints?

Hey everyone.

I have an earlier thread on here regarding an odd vibration I was getting in my 2008 JGCO CRD.

I've heard back from the dealer that we bought it from and their technician has diagnosed the problem as a seized main shaft u-joint. I spoke with them again and apparently the main shaft and u-joints is an unserviceable unit and requires a complete replacement part from Jeep. The cost is in the range of $1700.00 for the replacement part. I've been told that the component is rather unique in comparison to others the technician has seen.

The option I've been given is to have the main shaft sent to be rebuilt to replace the u-joints and to make the component serviceable in the future should one d them fail again.

Sorry for the newbish inquiry but I'm very new to this vehicle and have only ever owned FWD.

Has anyone heard of this?

I did a little digging this morning and think a clearer picture is starting to form:

I have not heard of any shops that can "rebuild" the OEM rear u-joints, but maybe someone figured out a way.

Here is a little newer thread on replacement drive shafts and u-joints. Some are reportably being sold on ebay now. http://www.jeepforum.com/forum/f67/g...views-3483658/

MOPAR does not sell servicing components for these driveshafts. When mine went bad, the entire rear driveshaft was replaced at ~$1,200. It also ruined the output seal on the transfer case, so that was replaced also. Luckily, powertrain warranty covered everything.
Have seen some posts in other threads that aftermarket suppliers now produce driveshafts with replaceable U-joints. You'll have to do a search on this forum for more specifics.

This is all great info.

Thanks everyone.

I heard back from my dealer. The shop that is rebuilding/building the driveshaft should have it completed by later this afternoon. By the sounds of it I believe it will be a newly built aftermarket component that will be serviceable in the future. It will come with a warranty as well.

I'll post more details as I get them.

Just heard back from my dealer.

The original shaft is unserviceable and was not rebuilt. A local shop that specializes in driveline parts built a custom piece with grease fittings and serviceable components. I'm going to assume it's probably identical to the one in the link I attached in a previous post on this thread.

The part came out to $760 CAD taxes in. I'll get the information of the shop and post it on this forum for anyone looking to have the same part built.

So here it is.

I snapped a pic of the underside of the Jeep this morning. Looks essentially the same as the custom built one in the link I posted earlier.



Here's the contact info of the location. They're located in Oshawa, Ontario Canada (just east of Toronto).

Looks good. How is it in terms of noise and freedom from vibrations?

I drove it 70km on the highway home. Under hard and gradual acceleration it stayed smooth. The vibration during deceleration is gone completely. There weren't any noticeable uncharacteristic sounds during the drive home. Just the sweet sound of the diesel at an unreasonably high RPM at cruising speeds (common' Jeep! At least one more gear!).

Thanks for the feed back. There are a number of driveline shops here so if I needed one made I could get it done locally. BTW our old '98 ZJ still has the original non greaseable (but serviceable ) joints in both the front and rear driveshafts. These models also used the same U joints in the front axle half shafts. Those are original too. 17 years old and 163,000 miles...

I just went through this on mine as well. What an idiotic piece of engineering. After some calling around, Indy Driveshaft in Indianapolis has a shaft in their catalog just for WK crd's. $395 and it was on my doorstep two days later. It's steel with normal U joints.

U joint replacement

Hi, I'm new to the forum. I just wanted to share with everyone another option in Toronto area. I took my drive shaft to a shop called Cardanic, they replaced the original u joint with a greasable one. This is good option since they remove very little metal so it keeps the strength. I've been driving the jeep since november and its worked great. They charge $250 CAD per u joint, I did both ends . Here is their info if anyone needs it

CARDANIC
175 Toryork Drive, Unit 61, Weston, ON
Tel: 416-743-6500
