TeraFlex 1744014 Factory Replacement Kit (JK Rzeppa CV)

Good quality, clear instructions. Relatively simple installation. Much better than the knock off brand I bought previously. Well worth the extra money to buy this one

Nice replacement for the old bearing and boot!! You would think that as much as you pay for them the bearings would all ready packed whit grease. Instead you get a plastic container of grease, with no applicator spout to fill in the voids of the bearing. The grease supplied is so thin that trying to pack it with the grease is messy and wasteful. I put masking tape over all the bolt holes and used a pair of plyers and smashed the grease tube flat to apply the grease in the voids. Now putting the bolts into the bearing requires long fingers or three hands, but it can be done it just takes a while!! The banding provided to secure the boot to the axle shaft was a failure. I just did it the old fashion way to I used two pieces of bailing wire to secure the boot to the shaft! Wala !!!

Fixed my issue with higher jeep driveshaft angle. Quick and in-expensive fix to keep the boot from ripping. Went wheeling with it and had no issues. The bolts are hard to install and glad the kit came with it's own tool to install.

Perfect fit, good quality, easy work.

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.

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!

I blew out the factory part mudding. I found out it is common on lifted wranglers. This part was an easy replacement and fixed the clunking in the front end that started while using 4x4, and gradually bled into 2x4. Highly recommend.

Replaced my front drive shaft u-joint on my 2013 Jeep Rubicon, old boot ripped, and grease came out and had a grinding sound and binding while in 4-wheel drive. Good quality and easy to install within an hour or so.

Quality product as advertised.
