TeraFlex1744014 Factory Replacement Kit (JK Rzeppa CV)

Good quality, only complaint is that the Allen socket broke.

Great product holds up to abuse, recommend

Fit well. Good quality. I have had it on for about 2 months and I am pleased.Getting it torqued down with their tool was the only challenge. It's a weird angle but it worked fine if you take your time.

Great price and very fast shipping . Came with everything I needed . Had tools to install but was a very good price and quality. Very pleased.

Fixed my front drive shaft noise in my 2012 jku

This kit addresses a flaw that Fiat/Chrysler should have addressed in the first place, especially on the front driveshaft to transfer case. There is very little clearance for the clamp for the boot for not rubbing and destroying the boot prematurely when traveling on uneven surfaces/roads. The Terra Flex replacement is great but is not a easy solution nor will it make taking the front drive shaft out for any type of other repairs easy. I replaced the joint on my 2015 2 door and it is straight forward for a mild mechanic. I would include a shorter 6mm ball hex in the kit to get the proper torque spec and specify engaging the rear cover atleast 95% on evenly for the unit to draw into the transfer case shaft properly. I would also include a second shorter boot clamp as beginners will screw the first up and the clamp is way to long and should not be doubled or tripled wrapped since clearance caused the failure in most case to begin with. I had this kit together and in in under 3 hours and using a deadblow hammer with a wood block to engage the rear cover to transfer case end almost fully should be in the instructions. The transfer case flange should be cleaned or lightly sanded or the 15ft torque lb spec will be inaccurate.I supported the driveshaft parallel to the transfer case for install with a adjustable jack stand to get it to go in straight. I would also measure the transfer case to Rzeppa joint bolt stick out since if the unit did not draw straight in which will cause the end 15ft lb torque to be in adequate to seat the upper part into the transfer case.Do Not use a power ratchet or Impact gun to Draw in the joint to transfer case flange!!! The bolts need to be drawn in slowly or flange with CV boot damage may occur.The longest part of the install was this and removing it may necessitate a new joint unit for the front driveshaft unless you clean it up good for rust etc. Overall this is a Great kit for the 3 Rzeppa joints found in the Jeep JK system,but better instructions are needed or premature fail or even catastrophic at highway speeds may happen.

I got this jeep with the shaft out. I bought this to rebuild the shaft. I put it in, but it would not fit properly. I torqued the bolts down, and drove down the road and all the grease slung out. I returned it as defective and just bought a new drive shaft. While putting it in I found broken bolts in the RZeppa flange on the transfer case. The previous owner failed to mention the broken bolts. I returned this think it was defective but it was not. I will buy again when needed.

When on the trails I heard a loud cracking and popping from under the Jeep, I could feel in in my shifter as I climbed my first trail. I knew something was wrong and sure enough when I climbed under my rig, I found that the boot for my front CV joint was completely gone. The original joint shown above was not designed for my 3.5" lifted Jeep and had finally failed.The new TeraFlex joint that I received was easy to install, had all of the parts and a comprehensive set of instructions. I had a much harder time getting the old one to come off than I did putting the new joint in. Once installed, I took my Jeep back out on the trails with no more cracking! Loved the install and love the product. Thanks TeraFlex!
