2008 Can-Am Outlander 800 Rear Suspension Parts Diagram: Complete Breakdown and Guide

If you own a 2008 Can-Am Outlander 800, understanding the rear suspension system is crucial for maintenance and repairs. This guide provides a detailed breakdown of the rear suspension parts diagram, explaining each component's role and how it contributes to the ATV's ride quality and durability. Whether you are replacing worn parts or troubleshooting a handling issue, this information will help you identify what you need.

The 2008 Outlander 800 uses a Torsional Trailing Arm Independent (TTI) rear suspension designed for a balance of comfort and off-road capability. The system consists of several key assemblies: the trailing arms, sway bar, shock absorbers, springs, and linkage components. Below, we dissect the diagram part by part.

Rear Suspension Assembly Overview

The rear suspension is mounted to the frame via pivot points. The main structural components include the left and right trailing arms, which connect the rear axle housing to the frame. A sway bar links both sides to reduce body roll. Coil-over shocks provide damping and spring support.

Trailing Arms

• Upper Trailing Arms (2): Connect the top of the rear axle to the frame. They control camber and toe during suspension travel.
• Lower Trailing Arms (2): Larger arms that bear most of the load. They attach from the bottom of the axle to the frame.
• Pivot Bushings: Pressed into the ends of each arm. These wear over time and cause clunking or loose handling.

Sway Bar (Stabilizer Bar)

The sway bar is a U-shaped torsion spring that connects the left and right lower trailing arms via drop links. It reduces body lean in corners. The sway bar mounts to the frame with rubber bushings. If you feel excessive body roll, check the bushings or the bar itself for cracks.

Shock Absorbers and Springs

• Coil-Over Shock Units (2): Each rear wheel uses a combined coil spring and shock absorber. The spring rate for the 2008 model is typically around 150 lb/in. The shock is a gas-charged twin-tube design with adjustable preload but not damping.
• Spring Preload Adjuster: A collar on the shock body allows you to increase or decrease spring preload for different loads.
• Shock Bushings: Mount at the top (frame) and bottom (lower trailing arm). Worn bushings cause side-to-side play.

Other Components

• Axle Housings: The rear axle is a live axle (solid) design. The trailing arms attach to the axle housings.
• Rear Wheel Hubs: Splined to the axles, with bearings.
• Brake Caliper Bracket: Mounted to the axle housing; the rear disc brake caliper bolts here.
• Parking Brake Assembly: Located on the rear driveshaft or within the brake system depending on model.

Common Wear Points and Replacement Tips

Over time, rear suspension components on a 2008 Outlander 800 will wear. Here are the most common issues:

Bushing Wear

Trailing arm bushings and sway bar bushings are rubber or polyurethane. After 10+ years, they can crack or soften. Symptoms include:

• Knocking noises over bumps
• Vague steering or wandering rear end
• Uneven tire wear

Replacement: Use OEM or aftermarket polyurethane bushings for longer life. Always replace both sides at once.

Shock Deterioration

Shocks can lose gas pressure or oil over time. Signs:

• Bouncy ride
• Bottoming out on large bumps
• Leaking oil on the shock body

Replacement: Several aftermarket options exist, from standard OEM replacement to adjustable shocks. For trail riding, a good choice is the Elka Stage 1 or Fox Podium RC2. Make sure to match the spring rate to your weight and accessories.

Sway Bar Link Damage

The drop links connecting the sway bar to the trailing arms can break. Symptoms:

• Rattling noise on uneven terrain
• Increased body roll

Replacement: These are inexpensive and easy to swap. Use heavy-duty links for aggressive riding.

Step-by-Step: Reading the Parts Diagram

A genuine Can-Am parts diagram is available from dealers or parts sites. Here’s how to interpret it:

1. Identify the Section: The diagram is labeled "Rear Suspension" (or "Suspension," "Rear").
2. Locate the Main Groups: The diagram is divided into assemblies: Trailing Arms, Sway Bar, Shocks, Hubs.
3. Use the Part Numbers: Each component has a number. Cross-reference with your VIN to ensure compatibility.
4. Look for Hardware: Diagram includes bolts, nuts, washers. They are crucial for reassembly.

Example: Part 700001234 might be the right trailing arm. Part 700001235 is the bushings kit.

Maintenance Schedule for Rear Suspension

• Every 50 hours: Inspect bushings for play. Grease pivot points if grease fittings exist (usually none).
• Every 100 hours: Check shock for leaks. Measure sag: adjust preload if needed.
• Every Season: Remove and clean the sway bar bushings. Re-grease if using polyurethane.
• Replace: Bushings every 2-3 years if riding hard. Shocks every 200-300 hours.

Final Recommendation

For a 2008 Can-Am Outlander 800, the rear suspension is robust but aging. Focus on replacing bushings with polyurethane and consider upgrading shocks if you ride aggressively. Always use a genuine parts diagram to ensure correct fitment. If you are not comfortable with suspension work, have a certified mechanic inspect the bushings and shocks. Proper maintenance will keep your Outlander handling well for years to come.

Remember, the diagram is your best friend—keep a copy in your shop. Check your local Can-Am dealer or online parts fiche for the exact 2008 diagram. Happy trails!
