| Lubricants | Maintain moving parts | Silicone spray, grease |
With these tools and materials at your disposal, you’ll be well-prepared to conduct a thorough inspection of your RV trailer suspension. Next, we’ll dive into the visual inspection process, where you’ll put these tools to good use.
Perform a visual inspection
Check for visible damage or wear
Begin your visual inspection by carefully examining the entire suspension system for any obvious signs of damage or wear. Look for:
- Cracks or bends in metal components
- Loose or missing bolts and fasteners
- Uneven tire wear, which may indicate suspension issues
- Sagging or uneven trailer stance
Inspect leaf springs
Leaf springs are crucial components of your RV trailer suspension. Pay close attention to:
- Cracks or breaks in individual leaves
- Misalignment or separation between leaves
- Signs of rust or corrosion between leaves
- Worn or damaged spring eye bushings
| Leaf Spring Condition | Action Required |
| Minor rust | Clean and apply rust inhibitor |
| Cracked or broken leaf | Replace entire leaf spring assembly |
| Worn bushings | Replace bushings |
| Severe corrosion | Replace entire leaf spring assembly |
Examine shock absorbers
Shock absorbers play a vital role in providing a smooth ride and maintaining stability. Check for:
- Leaking fluid or oil
- Dents or damage to the shock body
- Worn or damaged mounting bushings
- Excessive play in the shock rod
Look for signs of rust or corrosion
Rust and corrosion can significantly weaken suspension components. Inspect:
- All metal surfaces for signs of rust
- Areas where water may collect, such as U-bolt plates
- Suspension mounting points on the trailer frame
With the visual inspection complete, you’ll have a good understanding of your RV trailer’s suspension condition. Next, we’ll move on to testing the suspension components to ensure they’re functioning properly.
Test suspension components
A. Assess tire wear patterns
Evaluating tire wear patterns is crucial for diagnosing suspension issues in your RV trailer. Uneven wear can indicate alignment problems, worn suspension components, or improper tire pressure. Here’s a quick guide to common wear patterns and their meanings:
| Wear Pattern | Possible Cause |
| Center wear | Over-inflation |
| Edge wear | Under-inflation |
| One-sided wear | Misalignment or worn suspension |
| Cupping or scalloping | Worn shock absorbers |
Regularly inspect your tires for these patterns to catch potential problems early.

B. Check wheel alignment
Proper wheel alignment is essential for safe towing and even tire wear. To check alignment:
- Park on a level surface
- Measure the distance between tires at the front and rear of the axle
- Compare measurements – they should be equal
If measurements differ, your trailer may need professional alignment.
C. Evaluate axle condition
Axle condition directly impacts suspension performance. Look for:
- Bent or cracked axles
- Loose U-bolts
- Rust or corrosion
- Uneven spacing between axle and frame
Any of these issues warrant immediate attention from a professional.
Check suspension mounting brackets
Next, focus on the suspension mounting brackets. These critical components connect the suspension system to the frame. Inspect for:
| Aspect to Check | What to Look For |
| Loose bolts | Tightness and proper torque |
| Cracks | Hairline fractures or visible breaks |
| Rust | Severe corrosion or pitting |
| Alignment | Proper positioning and evenness |
Ensure all brackets are securely fastened and show no signs of damage or excessive wear.
Inspect equalizer condition
The equalizer plays a vital role in distributing weight evenly across axles. Examine it for:
- Wear on pivot points
- Proper lubrication
- Alignment with axles
- Signs of overloading or stress
Assess hanger condition
Finally, evaluate the condition of the hangers, which support the spring assemblies. Look for:
- Bent or distorted shapes
- Cracked welds
- Worn bushings
- Proper alignment with springs
If you notice any issues during this inspection, it’s essential to address them promptly to ensure safe and smooth travel. With the frame and mounting points thoroughly examined, we can now move on to evaluating the suspension bushings and bearings.
Evaluate suspension bushings and bearings
Inspect rubber bushings for wear
Rubber bushings play a crucial role in your RV trailer’s suspension system, absorbing shocks and reducing vibrations. To evaluate their condition:
- Visually inspect each bushing for signs of wear:
- Cracks or splits
- Deterioration or dry rot
- Deformation or flattening
- Check for any separation between the rubber and metal components
- Look for signs of rust or corrosion on the metal parts surrounding the bushings
| Bushing Condition | Action Required |
| Minor wear | Monitor closely |
| Moderate wear | Plan replacement |
| Severe wear | Replace immediately |
Perform maintenance tasks
Clean suspension components
Keeping your RV trailer suspension clean is crucial for its longevity and performance. Start by using a pressure washer or garden hose to remove dirt, debris, and road grime from all suspension components. Pay special attention to hard-to-reach areas where mud and salt can accumulate. For stubborn dirt, use a brush and mild detergent solution.
Lubricate moving parts
Proper lubrication is essential for smooth operation and reduced wear. Use a high-quality grease gun to apply lubricant to all grease fittings on the suspension components. Common areas to lubricate include:
- Leaf spring shackles
- Equalizer pivots
- Brake cam bushings
- Wheel bearings
| Component | Lubrication Frequency |
| Shackles | Every 3,000 miles |
| Pivots | Every 6,000 miles |
| Bearings | Annually or 12,000 miles |
Tighten loose bolts and nuts
Vibrations during travel can cause fasteners to loosen over time. Use a torque wrench to check and tighten all suspension-related bolts and nuts to the manufacturer’s specifications. Key areas to inspect include:
- U-bolt nuts
- Shackle bolts
- Equalizer bolts
- Shock absorber mounting bolts
Replace worn components as needed
During your inspection, if you notice any severely worn or damaged parts, it’s crucial to replace them promptly. Common components that may require replacement include:
- Cracked or delaminated leaf springs
- Deteriorated bushings
- Corroded or damaged fasteners
By regularly performing these maintenance tasks, you’ll ensure your RV trailer suspension remains in top condition, providing a smoother and safer towing experience. Next, we’ll discuss how to keep a maintenance log and schedule future inspections to stay on top of your RV trailer’s suspension health.
Regular inspection of your RV trailer suspension is crucial for ensuring a safe and comfortable journey. By following the steps outlined in this guide, you can effectively assess the condition of your trailer’s suspension system, from visual inspections to testing components and performing essential maintenance tasks.
Remember, a well-maintained suspension not only provides a smoother ride but also helps protect your trailer and its contents from damage caused by road vibrations and impacts.
