Review & Install Video
Today, we're going to talk through the installation of this kit, which I am going to give a two out of three wrenches. There's no major cutting or drilling necessary to get these installed. However, there is going to be a good bit of disassembly of your front axle to do in order to get these installed. So again, a two out of three wrenches, probably around three hours to get these installed. But we'll talk more about that install in a second. We're also going to talk through the construction and a few of the features of these ball joints. Ball joints are a wear item on any Jeep, and especially if you have big tires on your Jeep and/or you wheel it hard, you are going to wear out your factory ball joints quicker. So when you change them out, going to an upgraded, much stronger, heavier-duty set is definitely a good idea. These ones from Synergy are going to be the same metal-on-metal-style ball joint that you can get from some of the other manufacturers, and they're going to be right around the same price. Synergy has a good name. They make a high-quality part. I would definitely trust installing these in my Jeep, and I think they're a pretty good deal. These are designed to fit in either your Dana 30 or Dana 44 front end in your 1990 to 2006 Wrangler. They are going to come in a kit of four. So you'll have two upper and two lower ball joints to do your entire front axle. As I said before, these are a metal-on-metal ball joint, which is a little bit different from your factory ball joint that actually has a silicone piece on the inside of it. These ball joints are going to be greaseable. They come with all the Zerk fittings that you'll need to get them installed. One thing to point out is that these are a knurled ball joint. So if you don't currently have a knurled ball joint installed in your Jeep, you can go ahead and install a smooth ball joint, or you can go with knurled. But once you've installed a set of knurled ball joints like this one, you're going to have to stick with those. So that is one decision that you'll have to make. So like I said, I am going to give this a two out of three wrenches for installation. There's a good bit of disassembly of that front axle assembly to do in order to get these installed, and you're probably going to need to give yourself around three hours. In order to get a set of ball joints out, the best way to do that is by using a ball joint press. Of course, to get your new ball joints in again, a ball joint press is the best way. You can probably get a ball joint out by hitting it with a big enough hammer. But you always risk damaging that ball joint so that it won't come out easily, damaging your steering knuckle, and you're going to need that press to get the new ones in anyway. So go ahead and either purchase or rent a ball joint press before doing this job. Now, if all of this disassembly of your front axle isn't something you feel comfortable with, that's okay too. You can always take your vehicle to a shop and have those install these ball joints for you. However, if you do want to do this on your own in your driveway, it's certainly something you can tackle. The first step is going to be removing the tire. Then, you're going to have to remove the brake assembly, and in some cases also remove your axle from the axle assembly. Then, you can go ahead and unbolt the steering knuckle and remove it, finally removing the ball joints. The install process is going to be the same in reverse, pressing your new ball joints into place, putting your steering knuckle back together, reinserting your axle shaft, putting the brakes and, finally, the tire back on the Jeep. Again, about three hours, and you will need that ball joint press. This set of ball joints comes in at right around the same price as some of the other heavy-duty ball joints on the market that are going to be designed similarly. So as I said before, I think Synergy has a good name. They make a high-quality product. This does come with a 12-month warranty. So I would trust installing these on my Jeep. However, if you do have some brand loyalty to one of the other brands that makes a heavy-duty ball joint, like I said, they are going to be similar in price. So you can go with one of many options. So if your factory ball joints are worn out, either due to a large tire and/or wheeling your Jeep really hard, going with an upgraded set of aftermarket heavy-duty ball joints is a great idea. Going through this install will take a little bit of time. So if you can do it less frequently by installing a stronger part, I think that that is a really smart idea. So that's my review of the Synergy four-piece heavy-duty front ball joint set, fitting all 1990 to 2006 Wranglers, 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.
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.
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.
The Synergy heavy-duty front ball joint set is designed for use with Dana 30 and Dana 44 applications on 1990-2006 Jeep Wrangler YJ & TJ models.
