The 2011 Polaris Rzr 800 is a beloved machine, known for its rugged reliability and off-road prowess. However, like any off-road vehicle, it's not without its potential issues. One common headache for Rzr 800 owners is problems with the rack and pinion steering system. A failing or worn rack and pinion can significantly impact handling, making your rides less enjoyable and potentially unsafe.

What Exactly Is the Rack and Pinion, Anyway?

Let's break down what the rack and pinion actually does. It's the heart of your Rzr's steering system. Think of it as the translator between your steering wheel and the wheels on the ground. When you turn the steering wheel, it spins a pinion gear. This pinion gear meshes with a flat, toothed bar called the rack. The rack then moves left or right, pushing tie rods that connect to the wheels, causing them to turn. Simple in theory, but crucial for precise and responsive steering.

Common Symptoms: Is Your Rack and Pinion Screaming for Help?

Knowing the signs of a failing rack and pinion is the first step in getting it fixed. Ignoring these symptoms can lead to more serious issues down the road, and nobody wants that. Here are some tell-tale signs to watch out for:

  • Excessive Play in the Steering Wheel: This is a big one. If you can turn the steering wheel a significant amount (more than an inch or two) without the wheels responding, your rack and pinion might be on its way out. This "slop" in the steering makes it difficult to control the Rzr, especially at higher speeds.

  • Difficulty Steering: Is it getting harder to turn the wheel, especially at low speeds or when stopped? This could indicate internal damage or binding within the rack and pinion assembly.

  • Unusual Noises: Listen closely for any strange sounds coming from the front of the Rzr, particularly when turning the steering wheel. Clicking, popping, or grinding noises are red flags. Squealing might indicate a lack of lubrication or worn components.

  • Leaking Power Steering Fluid (If Equipped): Some 2011 Rzr 800 models came with power steering. If you notice leaks under the front of your Rzr, especially near the steering rack, check the power steering lines and the rack itself for damage. Low power steering fluid can cause hard steering and damage to the power steering pump.

  • Uneven Tire Wear: While uneven tire wear can be caused by several factors (misalignment, worn suspension components, etc.), a damaged rack and pinion can contribute to it. If you notice one tire wearing much faster than the others, have your steering and suspension system thoroughly inspected.

  • Wandering Steering: Does your Rzr seem to drift or wander, requiring constant steering corrections to keep it going straight? This can be a sign of excessive play in the steering system, often caused by a worn rack and pinion.

What's Causing All the Trouble? Root Causes of Rack and Pinion Failure

So, what's causing these problems in the first place? Several factors can contribute to the premature failure of the Rzr 800's rack and pinion.

  • Rough Terrain and Abuse: Let's face it, Rzrs are built to be driven hard. But constantly pounding through rough terrain puts a lot of stress on the steering system. Rocks, ruts, and jumps can damage the rack and pinion over time.

  • Lack of Maintenance: Neglecting regular maintenance, such as greasing the tie rod ends and checking for loose connections, can accelerate wear and tear on the rack and pinion.

  • Water and Mud Intrusion: Water and mud are the enemies of any mechanical system. They can contaminate the grease inside the rack and pinion, leading to corrosion and premature wear. Poorly sealed racks are particularly vulnerable.

  • Worn Tie Rod Ends: While not part of the rack and pinion itself, worn tie rod ends can put extra stress on the rack and pinion, leading to its failure. Tie rod ends connect the rack to the wheels, and if they're loose or worn, they can cause excessive play in the steering and transmit impacts directly to the rack.

  • Aggressive Driving Style: While fun, aggressive driving with lots of hard turns and sudden stops can put undue stress on the steering components, shortening their lifespan.

  • Manufacturing Defects (Less Common): Although rare, manufacturing defects in the rack and pinion itself can contribute to premature failure.

Diagnosing the Problem: Time to Get Your Hands Dirty (Or Hire a Pro)

Okay, you suspect your rack and pinion is acting up. Now what? Here's how to diagnose the problem:

  1. Visual Inspection: Start by visually inspecting the rack and pinion assembly. Look for leaks, cracks, or other signs of damage. Check the tie rod ends for play by grabbing them and trying to move them up and down or side to side. There should be minimal to no movement.

  2. Steering Wheel Play Test: With the Rzr on the ground, have someone gently rock the steering wheel back and forth while you watch the tie rod ends. If you see the steering wheel moving significantly without the tie rod ends moving, there's likely play in the rack and pinion.

  3. Listen Carefully: Have someone turn the steering wheel lock-to-lock while you listen for any unusual noises coming from the rack and pinion area.

  4. Check Power Steering Fluid Level (If Equipped): If your Rzr has power steering, check the fluid level. Low fluid can indicate a leak in the system, potentially from the rack and pinion.

  5. Professional Inspection: If you're not comfortable performing these tests yourself, or if you're still unsure of the problem, take your Rzr to a qualified mechanic. They have the tools and expertise to accurately diagnose the issue.

Repair or Replace? Weighing Your Options

Once you've confirmed that the rack and pinion is the problem, you have two main options: repair or replace.

  • Repair: In some cases, it may be possible to repair the rack and pinion. This typically involves replacing worn seals, bushings, or other small components. However, repair is usually only a viable option if the damage is minor. If the rack or pinion gears themselves are worn or damaged, replacement is the better choice.

  • Replace: Replacing the rack and pinion is often the more reliable and longer-lasting solution, especially if the unit is heavily worn or damaged. You can choose between an OEM (Original Equipment Manufacturer) replacement or an aftermarket option. OEM parts are typically more expensive but are guaranteed to fit and perform like the original. Aftermarket racks and pinions can be more affordable, but it's important to choose a reputable brand to ensure quality and reliability.

The Replacement Process: A DIY Adventure (If You're Up for It)

Replacing the rack and pinion isn't a walk in the park, but it's a manageable DIY project for experienced mechanics. Here's a general overview of the process:

  1. Safety First: Disconnect the battery to prevent any electrical accidents.

  2. Raise and Secure the Rzr: Use a jack to lift the front of the Rzr and secure it with jack stands.

  3. Remove the Wheels: Remove the front wheels for better access to the steering components.

  4. Disconnect the Tie Rod Ends: Use a tie rod end separator tool to disconnect the tie rod ends from the steering knuckles.

  5. Disconnect the Steering Shaft: Disconnect the steering shaft from the rack and pinion.

  6. Remove the Old Rack and Pinion: Unbolt the rack and pinion from the frame. You may need to disconnect any power steering lines (if equipped).

  7. Install the New Rack and Pinion: Install the new rack and pinion in the reverse order of removal.

  8. Reconnect the Tie Rod Ends and Steering Shaft: Reconnect the tie rod ends to the steering knuckles and the steering shaft to the rack and pinion.

  9. Bleed the Power Steering System (If Equipped): If your Rzr has power steering, bleed the system to remove any air bubbles.

  10. Reinstall the Wheels: Reinstall the front wheels.

  11. Lower the Rzr: Lower the Rzr back to the ground.

  12. Alignment: After replacing the rack and pinion, it's essential to have the Rzr's front-end alignment checked and adjusted. This will ensure proper handling and prevent premature tire wear.

Important Note: This is a simplified overview. Always consult your Rzr 800's service manual for detailed instructions and torque specifications. If you're not comfortable performing this repair yourself, take your Rzr to a qualified mechanic.
