Suspension Maintenance for Fifth Wheels & Travel Trailers
By Dustin Simpson | California RV Specialists
Leaf spring bushings may be small components, but they play a major role in your RV’s suspension system. These bushings act as a cushion between moving metal parts, helping absorb shock, reduce wear, and maintain proper alignment while towing.
At California RV Specialists, worn-out bushings are one of the most common suspension issues we see—and one of the most overlooked. Ignoring them can lead to costly damage and unsafe towing conditions.
What Do Leaf Spring Bushings Do?
Leaf spring bushings are installed at key pivot points in your suspension system, including:
- Spring eyes
- Equalizers
- Shackle links
Their job is to:
- Reduce metal-on-metal contact
- Absorb road shock and vibration
- Maintain proper alignment of suspension components
- Allow smooth movement as your suspension cycles
Without properly functioning bushings, your suspension system cannot perform as designed.
Why Leaf Spring Bushings Need to Be Replaced
Wear and Tear Is Inevitable
Bushings endure constant stress from:
- Road vibration
- Heavy loads
- Weather exposure
- Continuous suspension movement
Over time, especially with factory-installed nylon (plastic) bushings, they can:
- Wear down or flatten
- Crack or split
- Harden and lose flexibility
- Completely deteriorate
Poor Ride Quality
Worn bushings often result in:
- Rougher towing experience
- Increased vibration
- Squeaking or clunking noises
Replacing them helps restore a smoother, quieter ride.
Safety Concerns
Damaged bushings can directly affect:
- Trailer stability
- Suspension alignment
- Tire wear patterns
- Braking performance
In severe cases, worn bushings can lead to elongated bolt holes, loose suspension components, and potential system failure.
Prevent Costly Repairs
Neglecting worn bushings can cause:
- Premature wear on bolts and shackles
- Damage to equalizers
- Hanger deformation
- Frame stress and fatigue
Replacing bushings early is a simple and cost-effective way to avoid major suspension repairs.
How Often Should Leaf Spring Bushings Be Replaced?
Mileage-Based Guidelines
- Inspect every 12,000–15,000 miles
- Replace as needed based on wear and usage
Visual Inspections
Routine inspections are critical. Look for:
- Cracks or splitting
- Flattened or missing bushings
- Excessive movement in suspension joints
- Metal-on-metal contact
If any of these signs are present, replacement should be done immediately—regardless of mileage.
Annual Maintenance
Bushings should always be included in your annual RV suspension inspection, along with:
- Shackle links
- Equalizers
- Leaf springs
- Mounting hardware
Heavy Use Conditions
If your RV is:
- Frequently loaded near capacity
- Used on rough roads or off-road conditions
- Driven long distances regularly
Then bushings should be inspected and replaced more frequently.
Upgrade Options: Go Beyond Factory Bushings
Many RVs come with factory nylon bushings, which wear out quickly. Upgrading to:
- Bronze bushings
- Heavy-duty kits
- Wet bolt systems (greaseable bolts)
can significantly extend service life and improve suspension performance.
Why This Maintenance Matters
Leaf spring bushings are a small investment with a big impact. Keeping them in good condition will:
- Improve ride quality
- Enhance towing stability
- Extend suspension component life
- Reduce long-term repair costs
- Increase overall safety on the road
