      Review & Installation Video

      So OPR's front lower ball joint end that we're taking a look at today is going to be a good quality, factory-style replacement for the Mustang owner out there that's on a budget, and that need to replace a worn out or a broken joint. So some typical signs of a bad ball joint can easily be characterized by the following. You're going to be hearing some clunking. You might have some bad vibrations. But from personal experience, what I've felt in the past is that the steering wheel has a tendency to travel a little bit easier. Now, looking ahead to the installation, despite how small this sucker is, it's going to be a pretty involved one out of three wrenches on our difficulty meter here, and you should expect to be wrenching for about four hours. So manufactured from factory-style equipment, this direct fit replacement is going to be manufactured out of a block of fine-grain, high alloy steel. That's going to be for strength, as well as durability. Now, this is also going to feature a powdered metal gusher bearing with grooves. What that essentially means is that it's going to allow grease to flow through the joint to the stud, to ensure you're going to have a long life out of this part. Now, additionally, this is going to feature a patented press-in cover plate, which is going to help minimize deflection and give you better overall steering feel. Now, a great thing about this ball joint is that it is going to feature a grease relief valve, so you can flush out dirt and debris to extend its life. Now, the boot itself is going to be made out of a polyurethane compound that's going to be able to withstand dirt, abrasion, as well as high temperatures. Now, doing my job here, guys, I do want to call it out that this is a factory-style replacement, compared to the Whiteline option that we do have back on the website. It's going to be a difference of about $5. But between the OPR to the Whiteline, your main difference is only going to be the pressed-in cover plates. But on the flipside of the equation here, in comparison to the Steeda offering, that's going to run about $140. But that unit is going to be geared towards a lowered car, and they're essentially going to help get your suspension geometry back into check, give you better steering feel, as well as improve the handling overall. Looking at the pricing here, expect to be spending about $40 to $50 to get these onto your car per side. I will mention that if you were to pick these up from your local dealer, you would be looking at closer to around $100. Installation-wise, you should expect to be wrenching for about three to four hours. It is a very straightforward job, and we will be giving it one out of three wrenches on our difficulty meter here. Now, looking ahead here, guys, you're going to need the entire toolbox. There's so much needed that I'm going to have it listed right here. But at a glance here, guys, you're going to have to get that car off the ground. You're going to need to pull your wheels, tires, caliper, rotor. You're also going to need to disconnect the bottom of the strut from the spindle, as well as pulling out your factory spring. But once everything is out of the way, it's more or less just going to be getting your new ball joint end in place and reinstalling everything in the opposite order, then you're good to go. So that's going to wrap up my quick review of OPR's front lower ball joint end, fitting your 1994 through 2004 Mustang, which can be found right here at

        Definetly a good quality ball joint. Nice and stiff. Dont forget to read the directions on the cap. Couple thing I didn't like about these; there needs to be more grease inside them and the grease fitting doesn't come with a cap.

        After replacing the OEM joints from 95 and pressing the new ones in everything is perfect, no play very well built and having the grease zurks is a major plus over the factory ones

        It's supposed to move like that?

        The factory ball joints could be spun with my index finger with absolutely no resistance. That's not a good thing. I had to forcibly move these OPR's to get them to move. I was impressed with the quality and the fitment, it absolutely tightened up the steering system as a whole - and theres no more squeaking when the wheel is cut hard.

        Great replacement

        My front suspension about one year ago was starting to make unusual sounds after driving for about 10 mins or more. The sound was similar to the shocks were going out, but the ride quality was fine. I had my mechanic replace all shocks and struts 2 months ago, the sound was still there but he pointed out my ball joints needed to replace within a few months. Few weeks passed I order the OPR ball joints had my mechanic replace the old ones. I recently got a wheel alignment and now the sound went away and my mustang handles great. Current suspension setup: Eibach pro kit springs, Koni shocks and struts, SR Performance Front and Rear strut tower and OPR front lower ball joints.

      I just purchased tubular A arms. I was told the brand is QA1. Will these fit or does anyone have width and height of these?

      • If you have the street tubular A-arms from QA1 these would fit, however, their Race A-arms would have a specific type of ball joint.

      My front end squeaks horrible will these ball joints stop that.

      • The squeaking sounds coming from the front end are typically due to bad ball joints. However, in some cases, there could be other culprits as well.

      I need replacement ball joints but I just got my car and I don't want to cheap out on it. Would it be good to get the Steeda X2 Ball Joint Kit or the SR Performance Anti-Roll Ball Joint Kit even know my car isn't lowered?

      • We would recommend either the Whiteline replacement ball joints over the Steeda and SR Performance due to the ball joints being more ideal for lowered Mustangs. The Whiteline would be a great upgrade from the stock ones and would be great quality. If you were going to lower your Mustang shortly after replacing the ball joints then we would recommend the Steeda brand.
