If you've spent any time behind the wheel of a second-gen Cummins, you already know that a worn-out 99 dodge ram 2500 steering box is basically a rite of passage for owners. These trucks are absolute beasts, capable of pulling houses and running for half a million miles, but their steering systems have always been a bit of a weak point. If you're currently zig-zagging down the highway just to keep the truck in your own lane, it's probably time to stop blaming the wind and start looking at that hunk of cast iron bolted to your frame.
Driving one of these trucks with a bad steering box feels a lot like trying to steer a boat through a storm. You turn the wheel three inches to the left, nothing happens, then suddenly the truck decides to dive toward the ditch. It's exhausting, it's annoying, and let's be honest, it's a little bit sketchy when you're towing a heavy trailer.
Is Your Steering Box Actually the Problem?
Before you go out and drop a few hundred bucks on a new 99 dodge ram 2500 steering box, you've got to make sure that's actually what's wrong. These trucks have a "steering geometry" that's complicated, to put it nicely. You've got the track bar, ball joints, tie rod ends, and that pesky intermediate shaft. Any one of those can cause "the wander."
To check the box, have a friend sit in the cab with the engine off (but the key turned so the wheel isn't locked). Have them wiggle the steering wheel back and forth while you crawl underneath and look at the input shaft versus the pitman arm. If the shaft coming from the steering wheel is spinning but the pitman arm isn't moving an inch, your box has internal play. If you see fluid leaking out of the seals, well, that's a dead giveaway too.
Why Do These Boxes Fail So Often?
It's not necessarily that Dodge used "bad" parts, but the factory 99 dodge ram 2500 steering box just wasn't really beefy enough for the weight of the 5.9L Cummins diesel engine sitting right on top of it. When you add oversized tires into the mix—which almost everyone does—you're putting a massive amount of leverage and stress on those internal gears and bearings.
Over time, the teeth on the sector shaft wear down, or the bearings get just enough play in them that the whole assembly starts to feel loose. Most people try to fix this by tightening the adjustment screw on the top of the box. Pro tip: be careful with that. If you over-tighten that screw, you'll cause the steering to "bind," and it won't return to center after a turn. That's actually more dangerous than having loose steering.
Replacement Options: What Should You Buy?
When it comes time to swap out that old unit, you've got a few different paths you can take. Your choice really depends on your budget and how much longer you plan on keeping the truck.
The Local Auto Parts Store Unit
This is the most common route. You go down to the local shop, hand over your core, and get a "remanufactured" box. These are usually the cheapest option. They work, but they're often just a roll of the dice. Sometimes you get a good one; other times, the "new" box feels just as loose as the one you just took off. If you're on a tight budget, it gets the job done, but don't expect it to feel like a sports car.
High-End Remanufactured Boxes
If you want to do it once and never touch it again, brands like Red-Head or BlueTop are the gold standard. These companies don't just replace the seals. They actually machine the housings and install larger bearings to take out the factory "slop." Putting a BlueTop or Red-Head 99 dodge ram 2500 steering box in your truck is often the single best upgrade you can do for driveability. The difference in "on-center" feel is night and day.
The Borgeson Upgrade
Borgeson offers a heavy-duty box that's a bit of a different design. It's popular because it has a better variable ratio, which makes the truck feel a bit more modern. It usually requires a different steering shaft, though, so keep that in mind for your total budget.
The 6-Bolt Swap (The Modern Solution)
If you're really serious about fixing this once and for all, many guys are moving toward the "6-bolt" steering box from the newer 4th-gen Rams. It's a much larger, much stronger unit. However, it's not a direct "bolt-in and go" deal for a 1999 model. You usually need a different pitman arm and potentially some modifications to the lines. But if you're running 37-inch tires and wheeling your truck hard, it's worth looking into.
Tips for the Installation
Replacing a 99 dodge ram 2500 steering box isn't the hardest job in the world, but it is heavy and messy. You're definitely going to want a second set of hands when it comes time to lift the new box into place and start the bolts. That thing weighs a lot more than it looks.
Don't Forget the Pitman Arm Puller
You are not going to get that pitman arm off with a hammer and a prayer. Go to the tool rental place and get a heavy-duty pitman arm puller. Even then, you might need to hit it with some heat or an impact wrench. Those things get seized on there after twenty-plus years of road salt and grime.
Flushing the System
Don't just swap the box and top off the fluid. Your old fluid is likely full of tiny metal shavings from the old box's internal wear. If you run that junk through your brand-new steering box, you're asking for trouble. Flush the power steering pump and the lines thoroughly before you hook everything back up. It's also a great time to check your power steering hoses for cracks or leaks.
Bleeding the Air
Once the new 99 dodge ram 2500 steering box is in, you have to get the air out of the system. Jack the front of the truck up so the tires are off the ground. With the engine off, turn the steering wheel lock-to-lock about 20 or 30 times. Keep an eye on the fluid level. Once you stop seeing bubbles, start the engine and do it again. If you hear a loud whining noise, there's still air in there.
While You're Under There
Since you've already got the tools out and you're covered in power steering fluid, take a look at your steering stabilizer and the track bar. A lot of the "dead spot" in a 99 Ram comes from the track bar mount wearing out. If the box is new but the track bar is shifting side-to-side, you're still going to have that wandering feeling.
Installing a steering box stabilizer (also called a "sector shaft brace") is another huge win. It's a bracket that bolts to the frame and supports the bottom of the steering box shaft. It stops the shaft from flexing under pressure, which is one of the main reasons these boxes wear out in the first place.
The Final Result
It's honestly amazing how much better these trucks feel with a fresh 99 dodge ram 2500 steering box. You go from white-knuckle driving on the interstate to being able to relax and actually enjoy the ride. It makes the truck feel ten years newer.
If you're on the fence about spending the money on a high-quality box versus a cheap parts-store unit, my advice is to save up for the good one. These trucks are heavy, and the steering system takes a beating every single mile. Giving your Ram a solid foundation with a beefed-up steering box is something your hands (and your nerves) will thank you for every time you hit the road.
