Review: Perfect kit - Jeep fit to jl only
Review: Death Wobble Be Gone - 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.
