Review & Installation Video

Review & Install Video

I'm Ryan from extremeterrain.com and this is my review of the Synergy Ball Joint Set for all of you with either the Dana 30 or the Dana 44 axle in your 2007 and up JK. Today we are going to talk through the installation of this ball joint set, which I am going to give a two out of three wrenches. There isn't any major modification, cutting, drilling, or grinding necessary to get these installed, although you will need a ball joint press in order to get the old ball joints out and the new ones in. And there is a good bit of disassembly of your front axles to do in order to get access to the ball joints. So this isn't something that everyone is going to wanna tackle. If you do decide to tackle this on your own in your driveway, you are going to have set aside around four hours, but we'll get more into the installation in a bit. We're also gonna talk through the construction and a few of the features of these ball joints. A new set of ball joints like this is for those of you who have large, heavy tires on your Jeep and/or go off-roading a lot and have worn out the factory ball joints. The factory ball joints aren't going to last a long time with the big, heavy wheel tire package, heavy wheeling, or with a low backspacing on your wheels, which can push the wheel tire package away from the Jeep. Those are all things that will add additional stress and can wear out those factory ball joints fairly quickly. So an upgraded set like this is a great option if you're replacing your factory ball joints because you're going to get a lot more life out of these joints than you will if you just replace what you have with an OEM set that's exactly the same. These are going to be much, much stronger than those factory OEM ball joints are. Now, these are not an adjustable set of ball joints. You cannot adjust the preload on these like you can with, say, the Teraflex. These are much more of a traditional style ball joint that is just built very, very tough and is very, very strong. As far as construction goes, these studs on these ball joints are a heat-treated 4140 steel. All of the wear surfaces on the inside of the ball joint are metal on metal to give you that strength. These are, of course, a greasable ball joint. They come with these silicone grease boots and spring retainers. They also come with all of your castle nuts, your cotter pins, your Zerk fittings, all of the stuff that you're going to need to actually get these installed. Now, some of the grease fittings aren't your traditional Zerk fitting that you're gonna be able to attach your grease gun to and pump with grease. You will need a specific fitting for the end of your grease gun that is a pointed nozzle in order to depress the ball and fill that particular type of grease fitting. So keep that in mind when you're installing these. You may need that additional piece for your grease gun if you don't currently have it. As I said before, the install for these is going to be a two out of three wrenches, no cutting necessary. However, there is a good bit of disassembly of your front axle to do in order to get your old ball joints out and your new ones in. This is going to take around four hours, give or take, depending on your experience and the tools you have at your disposal. Now, as far as tools go, you are going to need that ball joint press that we talked about. It's not necessarily something you have to purchase, most auto parts stores will rent it or even loan it for free, but it is something you're going to have to have on hand in order to get this job done. So the first step in getting these ball joints installed is removing the tire and the brake assembly. Then you're going to be removing the outer C with the unit bearing and the axle shaft all as one piece to finally expose the inner C with the ball joints in place. You'll use your press to remove the old ball joints and press the new ones into place and then reverse that process in order to get everything put back together. Now, again, I know I made it sound simple, but there are a lot of smaller steps within that process that need to take place. This is going to be an involved install that not everyone is going to feel comfortable with, and that's okay. There are shops that will install these for you without a problem. Again, you'll definitely have to have all your hand tools handy, you're gonna have to have your ball joint press, and you're gonna have to have about four hours if you decide to do this in your driveway. Synergy is known for making really high-quality components, and their ball joints fall right into line with that. These are going to be a very strong ball joint that's gonna hold up really, really well, especially when you compare it to those OEM ball joints, but even when you compare it to some of the other aftermarket ball joints. So I don't think that the asking price of $200 is too much for these ball joints. I think that they are appropriately priced. However, if you are interested in something that's a little bit more modern, a little bit less traditional, the Teraflex ball joints that are adjustable, that are touted as the last set of ball joints you'll ever have to install, are only $40 more than these ones. And again, you can adjust the preload on those if they do start to wear out on you. So that is something to consider. If you're somebody who's a little bit more traditional and you want a more traditional style but very beefed up ball joint, that's where these fall into place and, again, appropriately priced. If you have 40 more dollars, if you want something that's adjustable that you can add preload to if they start to wear, the Teraflex ball joints are available as well. So if you have a big, heavy wheel tire package on your Jeep, you're running low backspacing on your wheels or even wheel spacers, and/or you wheel your Jeep hard, chances are your factory OEM ball joints are not going to last very long. And when it comes time to replace them, you might as well upgrade them to something that is much, much stronger than that original equipment on your Jeep, because these are gonna hold up a ton better than those factory ball joints ever would. So that's my review of the Synergy Ball Joints, fitting all 2007 and up JKs with either the Dana 30 or Dana 44 front axle, that you can find right here at extremeterrain.com.

Design and Construction. The Synergy Heavy-duty Front Ball Joint Set is an upgrade from stock which completely eliminates the old nylon liner style for extended durability and performance. The ball joint boots are made from durable wear and tear resisting silicone polyurethane.  Featuring a stud made from 4140 steel and induction heat treated bearing surfaces for the smoothest operation while maintaining the life of the ball joint.

Advantage. The Synergy heavy-duty ball joint set is ideal for replacing your existing factory-made ball joint sets especially if you're lifting your rig. Both the lower and upper ball joint pieces feature fully greasable metal-on-metal bushing design that offers high wear resistance, giving you more security than stock ball joints which are prone to premature wear on lifted Jeeps.

Warranty.  Synergy backs this heavy duty ball joint kit with a 12 month unlimited warranty, giving you full security and value for a solid year. Please see manufacture's warranty for full details.

Application. The Synergy heavy-duty front ball joint set is designed for use with Dana 30 and Dana 44 applications on 2007-2017 Jeep Wrangler JK models.

These ball joints are a huge improvement my 2011 Jeep Wrangler has never driven this tight and true with 35" tires.

Wow! What a difference, I forgot what it was like to drive with solid steering and no wandering or raddling on Michigan pot holes. Definitely worth the extra bucks for a bulletproof setup.

*SOME 2012 and ALL newer Jeep Wranglers come factory with larger front axle shafts (Dana 30 44) than previous years. Will it require any grinding? Thanks.

Just to verify, is this a full set of (4) ball joints plus hardware? This pictures for this product show one upper and one lower ball joint pair plus hardware, but the "whats in the box" tab for this product indicates (2) upper & (2) lower. Thanks.

    Fixed my death wobble!!!

    I replaced my factory ball joints at 48000 miles with these better designed units. I have 35" tires on a flat fender 2" lift and once I finished it I felt like it was a brand new Jeep it rode so smooth. Well worth the hassle. Pricier than other brands, but I trust the Synergy products.

    Great ball joints

    If you are lifted and have any size tires over stock, you will be looking for ball joints soon. You can tell these are pure beef. Nice boots, grease fittings, and heavy duty. Do yourself a favor.. When installing, MAKE SURE YOU PUT THE BOTTOM ONE IN FIRST! I slipped up and put the top in first on one side and it was a bad time. Even the weight of the jeep could not drive it in. Your standard autozone press will work with some ingenuity.

    Smooth Ride

    I was experiencing death wobble issues and noticed that my driver side ball joints where starting to get loose. I decided to just replace them all with these Synergy Dana Ball joints. I would have went with the TeraFlex ones instead but they where out of stock at the time. These ball joints fit with no problems, just a long 4 hours of labor. But to add to the death wobble issue I noticed my Stabilizer was getting leaky as well. So I got a new TeraFlex stabilizer figuring if i'm going to fix the problem i might as well do it right the first time. Now after all the new parts are on my steering feels just a tad tighter (not sure if its suppose to feel like that) but seems to take the bumps in the road better then it used to.

    Built well "BUT"

    I just order this set of 4 ball joints about 2 weeks ago and when I went to press the last ball joint in it snapped at the neck of the stem . Overall they were well built and have great movement . But the bad part is in order for me to get my Jeep on the road I went to get an Ac Delco ball joint from the local parts store .

    Synergy ball joints are a must have

    well built ball joint you can't go wrong with these. Wish I could get them for all my vehicles. Synergy ball joints are a must have for any jeep that sees off road action or has oversized tires.

    Great!

    Great product! Fit was good, giving it 4 stars on fit, because I could not get a standard grease gun to fit onto the zerk as stated in the instructions - I needed to grind out a small amount of material from the yoke of the axle. I greased these right after install, hoping they hold up longer than the OEM as so many before have stated.
