Review & Install Video
I'm Ryan from extremeterrain.com, and this is my review of the Alloy USA Heavy Duty Ball Joint Kit, fitting all 2007 and up JKs. These will work on both your Dana 30 and your Dana 44 front axle. So, regardless of which trim package Jeep you have, whether or not it's a Rubicon, these will work for you.
Today, we're gonna talk through the installation of this Ball Joint Kit which I am going to give a three out of three wrenches. This is a very involved install that does require a good bit of disassembly of your front axle, and it also requires a ball joint tool in order to install them. So, it is going to be something most of you are going to wanna take your Jeep to have installed. We're also gonna talk through the construction and a few of the other features of these Ball Joints. This Ball Joint Kit is for those of you who have worn out ball joints either because you have big tires, you have little back spacing on your wheels, and/or you wheel your Jeep really hard. A lot of the modifications we do to our Jeeps will wear out a set of factory ball joints pretty quickly, even if you have a bone stock Jeep, eventually ball joints will wear out. They're simply a wear item.
So, if you're going to replace them, you might as well replace them with something that is heavier duty and going to last longer than the OEM set will, and that's where these come in. Alloy USA has a good name in suspension and drive train components, they've been around for a good long time. And these are a very well-built, very strong set of ball joints, that are priced right around where most of the other sets on the market are priced.
As I said before, these are going to be a lot stronger than an OEM ball joint, and they're gonna hold up a lot better. These do have a chromoly ball joint shaft, they have a carburized alloy housing. These are greasable, they come with polyurethane grease boots to keep the grease in and the dirt out, and these are greasable ball joints. So, you are going to be able to service the ball joint, keep them lubricated, which will keep them alive a lot longer. Now, these are a knurled ball joint and the factory ones are not. If you have a ball joint seat that is a little bit worn and that has a little bit of play in it, using a knurled ball joint is a good way to make sure that the ball joint is going to fit really tight.
However, if you don't have a lot of play and you have a regular smooth ball joint seat, getting a smooth ball joint isn't a bad idea either. It's really up to you what you would prefer and what you wanna install in your Jeep. These do come with, of course, the castle nuts, the grease fittings, everything that you're going to need to get them installed. This is a set of four ball joints, you're gonna have upper and lower for both the left and the right side. It is a complete kit and again, it is very well-built.
The one thing that is different about these, than say the TeraFlex ball joints is that, these are not adjustable. This is more of a standard ball joint, although it is very strong. TeraFlex does make something that for about $40 more, you can get an adjustable ball joint, that you can adjust the preload on so, when they do start to wear out you can adjust them, you don't have to swap them out. These are not going to be those, these are much more of a standard non-adjustable ball joint, although again, they are built very, very well. They are very, very strong and they're gonna hold up a lot longer than an OEM ball joint would.
As I said before, the install for these is going to be a three out of three wrenches. In order to get these installed, first you're going to have to remove your tire, your brakes and the complete unit bearing from the outside of the axle including the axle shafts. From there, you'll be able to remove the outer seat and finally use a ball joint press tool to press the old ball joints out of their seats. After that, it's just a matter of pressing the new ones in place, reinstalling the seat, the axle shaft, unit bearing, your brakes and, of course, your tires.
It does seem like it's a pretty straightforward process, and all in all it is. If you decided that you wanted to tackle this on your own, you could purchase, or even rent, or borrow for free a ball joint press tool from most auto parts stores. However, you're not gonna be able to do the job without that tool. So, if you do decide to do this on your own, make sure that you get that tool and have it on hand before you get started. Other than that you're not going to need a lot of specialty tools, but I would set aside around four hours to get this installed completely.
These ball joints are priced right around where most other sets of standard non-adjustable ball joints are priced, give or take $20. And as I said before, when you start looking at ball joints in the way that they are constructed, these are built very well, all of the wear surfaces are hardened, these are going to hold up for a good long time. If you do have the budget for it, you wanna spend 40, 50 more dollars, you can get an adjustable set of ball joints from TeraFlex that are going to last even longer, because when they do start to wear out you can adjust them. However, if you're looking for a standard set of non-adjustable ball joints, these ones are priced right and very well built.
So, whether you've worn out your ball joints from just putting a ton of miles on your JK, or worn them out a little bit quicker because you have large tires, low backspacing on your wheels, or you just wheel really hard. These are going to be a high quality and well-priced replacement.
So, that's my review of the Alloy USA Heavy Duty Ball Joint Set, fitting all 2007 and up JKs, that you can find right here at extremeterrain.com.
