Hey folks, if you’ve ever worked with inner ball joints—whether you’re a mechanic, a parts buyer, or someone who just likes to tinker under the hood—you know these little (but super important) parts don’t mess around when it comes to being stored wrong. I’ve been supplying inner ball joints for over 12 years now, and I’ve seen way too many good parts get ruined because someone stuck ’em in a dusty corner or stacked ’em heavy on top of other metal bits. Today I’m gonna break down exactly how to store these things right, no fancy jargon, just real talk from someone who’s shipped thousands of these bad boys out the door and watched how people handle (and mess up) storage. Inner Ball Joint
First off, let’s get one thing straight: inner ball joints aren’t just random metal and rubber chunks. Most of ’em have precision machined surfaces, rubber dust boots that seal out dirt and water, and even tiny internal bearings that get easily gunked up if they’re not cared for. I once had a regular customer send back a whole pallet of inner ball joints because when he installed ’em, the boots cracked and let in sand, and turns out they’d been stacked on top of a stack of heavy brake calipers in his warehouse for 6 months. That was my wake-up call to write this—don’t let that happen to you.
Let’s start with the basics: where you actually put these things. I know, I know, everyone’s got a “spot” in their garage or warehouse, but not all spots are created equal. First rule: NO damp areas. I don’t care if your shop is in a basement or a back room that floods when it rains—inner ball joints hate moisture. Why? The steel parts will rust, even if they’re coated. You might not see rust right away, but give it a few months and that tiny surface rust will catch inside the boot or on the ball stud, and when you go to press it into a control arm later, it’ll scuff up the surface and cause it to fail early. I’ve had way too many warranty claims come back because of rust from bad storage, so take this part seriously. And don’t even think about storing ’em in an outdoor shed. I don’t care how well you seal the door—bugs, rain, temperature swings, all that crap will mess ’em up fast. Keep ’em inside, in a space that’s climate-controlled if you can swing it, but at least somewhere that doesn’t get standing water.
Next up, how to position ’em when you store them. This is another big one. I see people all the time lay inner ball joints flat, or stack ’em on top of each other like they’re pancakes. That’s a no-go. Here’s why: the dust boot (the rubber part that keeps dirt out) is soft. If you set a heavy part on top of the boot, it’ll stretch it out of shape, or even tear it, before you even use the part. And the ball stud—the part that sticks out to connect to the steering knuckle—if you stack heavy stuff on top of that, it’ll bend. A bent ball stud is impossible to install right; you’ll have to hammer it, which ruins the precision, and it’ll wear out way faster. So what’s the right way? Hang ’em, or stand ’em upright. Wait, let me clarify—stand ’em so the ball stud is pointing straight up, not to the side. If you stand ’em on the non-ball stud end (the flat part that bolts to the control arm), that’s fine. Or if you have hooks, hang ’em by that same flat mounting flange. That way, there’s no pressure on the boot, no weight bending the stud, and air can circulate around every part of the joint. I keep all my replacement stock in plastic bins with built-in slots for hanging, and it’s saved me so much hassle with damaged parts before they even leave my warehouse.
What about wrapping or covering them? A lot of guys think wrapping ’em in plastic wrap is a good way to keep dust out, but hear me out—if you wrap them too tight in plastic, you trap moisture. Even if the parts were dry when you wrapped ’em, any tiny bit of moisture in the air will get sealed in, and that’s a recipe for rust. The exception is if you use breathable plastic—like the stuff that’s made for storing metal parts, it lets air flow through while keeping dust out. Or, my go-to: use brown paper or corrugated cardboard sleeves. I keep a stack of cardboard boxes that are the perfect size for a single inner ball joint, so I can slide each one in, close it up, and stack the boxes without crushing the joints. The cardboard keeps dust off, it’s breathable so no moisture gets stuck, and you can label each box with the part number, vehicle it fits, and the batch number—super helpful if you need to find a specific part fast later. Avoid using plastic bags unless they’re perforated. And whatever you do, don’t leave the packaging the parts come in from me (or any supplier) lying open. That cardboard box I ship in is designed to protect the part for storage too—don’t toss it out after you unbox the new ones.
Now, what about temperature and how often you check on them? A lot of people forget about temperature, especially if they live somewhere that gets super hot in summer or freezing in winter. Extreme temperatures are bad for the rubber dust boots. If it’s too hot, the rubber will get soft and stretch, and if it’s too cold, it’ll get brittle and crack. I’ve seen boots crack just from being stored in an unheated garage in Minnesota during January—no damage from installation, just the cold making the rubber brittle. So try to keep the storage spot between 40 and 80 degrees Fahrenheit, if you can. If you don’t have a climate-controlled space, at least keep them away from windows that get direct sunlight for hours every day—sunlight does the same thing as heat, breaks down the rubber fast. And how often do you check on them? I do a quick check once every 3 months. Just pull a few joints out, look at the boots for cracks, make sure the ball studs aren’t bent, and wipe off any light dust with a dry rag. It takes 5 minutes, and it can save you from having to replace a whole batch of parts that went bad from sitting in a forgotten corner.
Wait, what if you’re storing inner ball joints long-term—like more than 6 months? That’s a different scenario, and I get it, sometimes you have to buy parts in bulk to save money. If that’s the case, there’s a couple extra steps. First, make sure you grease the ball stud lightly with a thin coat of lithium grease before putting them into storage. Wait, not too much—just a thin layer, so it doesn’t attract dust. That grease will protect the steel from rust even if there’s a tiny bit of moisture in the air. Second, if you’re stacking boxes (and I really only recommend stacking 2 high max, even with cardboard—more than that and the bottom boxes will get crushed), put a layer of foam or cardboard between the boxes to take some of the weight off the ones below. Third, mark the date you put them into storage on the box. I follow the “first in, first out” rule, so I use the oldest parts first, which makes sense—parts don’t last forever in storage, even if you do everything right. I’ve seen parts go bad after a year in storage just because the rubber boot dried out, so don’t hoard inner ball joints longer than a year if you can help it.
And let’s talk about the mistakes I see all the time, just so you can avoid ’em. First, storing them near chemicals. I once had a customer store a pallet of inner ball joints next to a bucket of brake fluid in his workshop. The brake fluid fumes ate through the rubber boots on half the joints—total loss. So keep them away from any chemicals, solvents, cleaners, anything that has strong fumes. Second, not labeling them. If you have a bunch of different inner ball joint sizes, you’ll mix ’em up in no time, and when you need one for a job, you’ll be digging through a pile of parts for 10 minutes, which is a waste of time. Third, dropping them. I know it sounds silly, but a quick drop on the concrete can mess up the internal bearings inside the joint, even if you don’t see a scratch on the outside. Those tiny bearings are precision parts, and a hard bump can make them wear out early. So treat inner ball joints like the precision parts they are, not just another metal thing.
Here’s the thing: inner ball joints are a critical part of a car’s steering and suspension. If they fail while you’re driving, that’s super dangerous. Storing them right isn’t just about saving you money on warranty claims or replacement parts—it’s about making sure they work when you need them to. I’ve been in this game long enough to know that most parts failures that get blamed on bad parts are actually from bad storage before they even get to the installer.
