Review: Fixed my occasional death wobble! - If you're on the fence about buying these ball joints, let me assure you they're worth their weight in gold! I installed a Teraflex leveling kit for my 2015 Wrangler JKU and immediately started to experience an occasional death wobble. I was told by my wheel alignment shop that my tie rod ends and ball joints checked out fine. Since my ball joints "were fine" I decided to install a Teraflex adjustable track bar front and rear but that didn't fix the issue. I debated new tires because they're 4 years old, but decided to take the cheaper route and bought the Teraflex Ball Joints. I always had a shimmy in the steering wheel at all speeds and now a severe wobble in the 45-52 mph range. As soon as I drove the Jeep down the block with the new ball joints installed I knew right away the problem was fixed. No low speed shimmy no death wobble in the 45-52 mph range. Just a rock solid steering wheel. If you have a wobble in the front end, get off the fence and buy these Teraflex HD Ball Joints....IT'S THE BALL JOINTS!! Also, the photos in the description are the old style joints, I received the newer ball joints with the dual grease Zerks on the lower joint.
