4 Best Ball Joints for Jeep JK & TJ

by | Auto Tools, Best Of (Cars)

OEM Jeep ball joints come and go. They’re usually decent, but you can’t expect any tremendous performance or durability. After all, we’re talking about OEMs.

At one point you have to change them and you find yourself at a crossroads. There are a lot of brands that manufacture quality ball joints for Jeep – be it Wrangler or TJ.

The Holy Trio is Dynatrac, Synergy and Teraflex, no doubt about that. You also have really budget-friendly brands like Moog or Alloy USA.

Which one of these manufactures the best ball joints for Jeeps?

Tricky question – and it also depends whether you drive a JK/Wrangler or a TJ.

For JK/Wrangler owners, lot of people swear by the legendary Dynatrac ProSteer, even though they’re quite expensive.

Why? They’re made of military-grade stainless steel and have Teflon coating for extra long life. Unlike other kits, they’re also rebuildable…and manufactured in the US too.

For Jeep TJ owners, this Synergy ball joint kit will get you the most reliable performance in the long-term. Other TJ kits from Teraflex, Moog aren’t as good and I haven’t seen a Dynatrac TJ kit yet.

Before I get to the concise comparison table Jeep ball joint reviews, I want to discuss something else.

A lot of Jeep owners are surprised when they get a quote on the removal/installation of their ball joints. You can easily spend a lot if you hire someone else to do it. I’m talking about several hundred bucks here.

Changing the ball joints yourself isn’t particularly hard, but it takes time. If you decide to do it, you might lose half a day or so, but you’ll save quite a bit of money.

If you decide to DIY, don’t forget to grab a ball joint press kit. I recommend this one, as it supports the Dana 30/44 front axle on Jeeps and Astro manufacture great quality kits.

Here’s one example video of changing the Dynatrac ProSteer ball joints:

As for the comparison table, here’s a quick comparison between the 4 best ball joints for Jeep Wrangler/JK I can vouch for.

Honest recommendations:
4 best ball joints for Jeep JK & TJ

1. My top recommendation for Jeep JK ball joints:
Dynatrac ProSteer

No compromise. This is the tagline I’d attach to this set of Dynatracs. Manufactured locally on Americal soil, they come built-in heat-treated stainless steel that lives up to military standards. To enhance this tough construction, there’s also Teflon coating on the wear points so you can say goodbye to premature wear.

A big plus here is the fact that this set of Jeep ball joints is both rebuildable and easily greaseable.

This is the holy grail for any owner! You not only have the “basis” – a solid construction, but you also have the means to prolong it further by lubricating with grease. And if despite this something happens, you can rebuild your kit.

I guess you can understand why Dynatrac ProSteer is considered a masterpiece, right?

I’d also call them the “Death Wobble Killer” as the performance improvement and overall ride stability they give you is unmatched.

An absolute beast for any terrain, and especially recommended for you crazy off-roaders. The only downside is the price, but I think it’s well worth it.

2. Best value for the price
Tie: Synergy vs Teraflex ball joints for TJ/JK

To me, Synergy and Teraflex are virtually the same in terms of what they offer you. Price-wise too…

Both of them are better constructed and more durable than your typical OEMs that can even include plastic parts. Yikes.

Let’s cut to the important details: both of them can also be greased easily, but are not rebuildable. You will see your death wobble fixed and enjoy better driving, but you won’t have the full set of luxuries like the Dynatrac kit.

Also, both brands work with RCV shafts for those of you who are into this 🙂

If you plan on doing more off-road adventures, go for the Teraflex like these. Just keep in mind that these are not suited for extreme off-road driving.

Terraflex ball joints for Jeep JK or TJ: a few words on what to know.

The main difference between these two lies in what generation Jeep you actually drive.

As far as ball joints for Jeep TJ go, Synergy has a more reliable ball joint kit. I’d recommend considering it as your best bang for your buck pick if you’re a TJ owner.

Teraflex’s best kits only support Jeep JK 2007-2012, so anything outside this timeframe will demand some modifications. Here’s the Synergy TJ set:

Best ball joints for Jeep TJ - well, Synergy outperforms Terraflex here for sure. Here's the recommended set I have for you.

As with the Dynatracs, installation is not rocket science. In some kits you also have some hardware parts that will make the task easier for you. Here’s a video of changing to the Synergy ball joint kit for Jeep Wrangler:

3. Budget consideration:
Alloy USA ball joints

Alloy USA is pretty much comparable to Moog in my opinion. Their Jeep ball joints are decent, but definitely a step behind the brands I talked about above.

The big advantage you have with these is affordability. Keep in mind this kit includes knurled ball joints. Also, while you can grease them, the process can be a bit trickier than other higher-end Jeep ball joint brands.

A good solution to this trickiness is to make sure their fitting is facing forward when you press them in. Grabbing a needle nose adapter together with your kit is a good idea. Even then they’re not as easily greaseable.

That said, these perform significantly better than OEMs and cheaper alternatives. A decent choice for those of you who don’t care much about extreme terrain and stick to usual road infrastructure.

Recommended for budget pickers, but if you can upgrade your budget I’d go for the more premium ball joint kits.

As a closure

I consider ball joints to be a fundamental part of any vehicle. In this sense, I’d advise you to invest in a proper set of these. It might not be Dynatrac if they’re outside of your budget…but don’t be cheap here.

The four choices I presented you with work well in varying degrees. All of them are without a doubt a huge improvement over the OEMs you’ve driven so far. They’re also better than other brands like Moog for example, who I otherwise recommend for other vehicles.
