TeraFlex3442022 JK Dana 30/44 Complete Knurled Ball Joint Set, 1 Pack

I have been battle very flighty steering and bump steer for about 2 years now on my 2010 JKU (non-Rubicon). I have replaced just about every component of my front steering over the last 18 months; u-joints, ball-joints, springs, shocks, tie rod, track bar, drag link, upper and lower control arms, all front and rear suspension bushings. Nothing really seams to help. These ball joints were part of a larger upgrade I did a few days ago. Here's the story on the ball joints: I bought some Moog ball joints to replace my well worn factory ones about 15 months ago. I never liked them. They felt very loose and my steering got worse and worse until I finally decided to bite the bullet and get these Terflex HD Ball Joints. I was originally a bit nervous about spending twice as much for ball joints, but I wish I had done so sooner.These HD ball joints came in the prettiest car parts box I have ever seen. It included easy to follow instructions with pictures. About the only thing that didn't come in the box that I would have liked to have seen was grease zerk covers, but I had some on hand.Installation was a breeze. After tearing down the front drive/steering, I pressed out the old ball joints. Then used a wire wheel in my drill to clean up all of the surfaces and remove any rust that was present. Then I greased both the ball joint and c-arm mating surfaces. The new joints pressed in nicely. It is worth noting that you should really read the details on how to position the lower ball joint so that the grease zerks are accessible; especially if you have RCV axles! Once the ball joints are pressed in, you need to reinstall the grease bushing on the upper ball joint. This can be a little tricky as the hole in the c-arm is deeper than the ball joint body in the back. I managed to get mine on by using a little bit of grease and then pressing and spinning the bushing until it had seated all the way around. Install the grease zerks, but don't grease them until you have reinstalled your steering knuckle. Once your steering knuckle is reinstalled and torqued down, throw in the cotter pins and grease the joints liberally. (I also replaced my axles, u-joints, hubs and bearings at the same time as I installed these ball joints).Once everything was back together, I took my rig for a spin and the difference was immediately noticeable. Initial results show no signs of flighty, wandering steering. Bump steer is gone. I will keep an eye on these new ball joints through the new break-in period and update this review if anything changes. But, as of right now, I couldn't be happier.So, if you are on the fence about whether or not to buy these TeraFlex HD Ball Joints, pull the trigger. You won't be disappointed!

Very happy. Tightened up my steering and made the car run solidly over bumps. Glad I went with these. Installed in 3 hours with the help of a friend and the right tools.

2010 jk. first time I've replaced ball joints in this jeep. passenger side tire was leaning in at about 3degrees negative camber, thought it was a bent c. steering wheel was way off center. had a vibration at 55 mph. cured every one of those issues. drives like the day we got it. fairly easy install with clear instructions. highly recommended.

These are super nice and great quality. Go with these over the others! There are knurled as well.

Save yourself from frustration and rework. These adjustable ball joints are JUNK. The set screws don't hold the nut at torque specs specified by TF. The adjustable nuts would either tighten up or lossen while driving. The joints are way to tight when set to torque specs specified by TF. If you can reach the torque spec with the JUNK little wrench they send with the set. If their product was as good as the packaging they may have something. Just a couple of weeks trying to dial things JUNK joints in and now removed and put in another brand that work flawlessly. The TF tie rod and drag link are the same JUNK joints also. Save your money and go someplace else. The seller will not do anything to rectify the situation so now I have some paper weights in the shop.

These are great. I previously had synergy and they did not last. I also lile that you can adjust these. Install was just like any other. No trimming needed.

Best ball joints on the market other than Rare Parts ball joints at half the price. Good quality.

These seemed to be very well built ! I unfortunately miss understood the part that is adjustable ! I needed offset ball joints ! Fast shipping good price for quality of parts ! Jk jeep people need these ! Great packaging as well

As described

Traía unas marca Synergy en un Rubicon 2010, estas nuevas Teraflex las superan en calidad, aparte que la inferior es ajustable al desgaste y trae graseras, muy buen producto, me sorprendió hasta el empaquetado de primera

Tel qu'annoncé

I bought this product thinking it was the best quality and so far so good. However, after installing one side top ball joint, I realized that there was no thread on the hole for the grease zerk. I had to remove the new ball joint and ask for a new set to take the good ball joint from the new set and return the set with the bad ball joint. However, it was fast to receive the replacement set. 3 stars because of the lack of quality control.
