TeraFlex JL/JT Dana 30/44 HD Ball Joint Kit w/out Knurl

Jeep fit to jl only

These ball joints made my day. I have a 2018 Jeep Wrangler JLU Rubicon V6 and it had been suffering from the dreaded death wobble issue. I went to three different shops, and they all gave me advice on what needed to be replaced so I followed their advice. However, nothing they suggested completely resolved my DW problem and I went to two different off-road shops and a Jeep dealership. Before experiencing DW, I added a Mopar lift. Once I started experiencing the DW issue, I installed front and rear adjustable track bars. Next, I installed a new Synergy tie rod and drag link. Also, I installed a new steel steering gear box which was recommended by the dealership and an off-road shop. The parts reduced the frequency of DW but did not fully cure the problem. After doing much research, I came a across an article on a Jeep forum that mentioned the OEM ball joints in 2018-19 Jeeps are not very good. They use a metal on plastic architecture which doesn't last long especially if you have over sized tires or spacers. Who buys a Jeep without adding larger tires or spacers? Anyway, I mentioned to the dealership that this may be the issue and they told me that the ball joints had nothing to do with the DW issue. Regardless, I took a leap of faith and purchased these TeraFlex ball joints based on quality and affordability. I must say they did not disappoint. They are made very well, much better than the OEM ball joints. The greatest thing of all is that I have not experienced one death wobble incident since I installed them. Before I would I have to pull over 3 times if I drove 10 miles anywhere. These are well worth the price. I installed them myself and it was my first-time installing ball joints. They are a little difficult to install but any install for ball joints would not be easy.

Solid ball joints! Alittle tough on the install unless you have the right tools. Fixed my death wobble and seems sturdy.

Make sure to watch the video on the Terraflex site before you get started. The ball joints are directional and not the same length. Great build quality, easy installation (if you know how to install ball joints in the first place) and they made my JL drive like a new vehicle at 73k miles. You'll want an alignment after they are installed.

The factory Jeep JL ball joints are garbage, mine only lasted 50K miles. I had a completely new suspension and was still getting a shimmy at higher speeds when hitting big bumps. Tested the ball joints and couldn't really see any noticeable play. Knowing how bad of a design the factory ball joints were I decided to install these for piece of mind. Completely eliminated my shimmy and Jeep drives great again. Teraflex makes good products. I highly recommend.

2022 Jeep Gladiator, 38x13.5 inch MT Baja Pro Xs tires. With only 9k miles. The puny, non-serviceable factory ball joints just didn’t hold up (4th photo shows a factory ball joint.) Packaging was excellent. The install was easy, the included instructions were very comprehensive, and included torque specs for everything that had to be reinstalled after the ball joints. Took about 3 hours to complete install. The grease fittings are easy to service on the vehicle and the preload adjustment is as well. The ball joints even came with the tool to make the on-vehicle preload adjustment with. These are an excellent value and definitely better than what came from the factory.

Steering was pulling right and also somewhat in any direction depending on road contour. This tightened up the steering.

Had some movement in my factory ball joints, upgraded to these and completely eliminated death wobble. Very happy with this upgrade. Was even able to install myself with an adapter kit so saved myself at least $1000 from the dealership.
