I purchased a new/used set of these ball joints for my Jeep Gladiator. I know buying open box anything comes with risk, and as you can see, this product was damaged from a previous buyer who must have returned them. My guess is that someone tried pressing the new ball joints in and crushed the top of the ball joint where the grease zerk goes. This makes installing the grease zerks impossible without drilling and maybe gluing the serks into place.If you buy these used, check for this damage BEFORE you take your Jeep apart

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.

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

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.

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.

Ordered for someone else to replace the the ones on their 2021 gladiator. I think one fit? Not sure if was lower or upper but the other didn't fit? Not very sure since I only helped with the order and not with looking up parts or the repair.

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.
