MDC Suspension Bush Replacement – Camper Trailer Suspension Repairs

MDC Suspension Bush Replacement Caboolture

Looking for professional MDC Suspension Bush Replacement or Camper Trailer Suspension Repairs? At Caravan Mechanic and Detailing Service, we regularly repair and replace worn suspension bushes on MDC camper trailers, Market Direct Campers, off-road camper trailers and caravans throughout South East Queensland.

Recently, an MDC camper trailer was booked into our workshop for a Camper Trailer Roadworthy Inspection. During the initial inspection, we identified a serious suspension issue that would have ultimately resulted in suspension failure if left unattended.

The polyurethane suspension bushes had almost completely deteriorated, leaving very little bush material remaining between the suspension components.

This is a surprisingly common fault that we regularly encounter on MDC camper trailers and other off-road camper trailers fitted with polyurethane suspension bushes.

Suspension Repair

What Are Suspension Bushes?

Suspension bushes are designed to isolate metal components within the suspension system while allowing controlled movement.

They help:

✅ Reduce vibration

✅ Absorb road shock

✅ Maintain suspension alignment

✅ Reduce noise and squeaking

✅ Protect suspension components

✅ Improve towing stability

Without properly functioning suspension bushes, excessive movement occurs throughout the suspension system, causing accelerated wear and poor towing performance.

Common Signs You Need MDC Suspension Bush Replacement

Many camper trailer owners don't realise their suspension bushes are worn until a roadworthy inspection or major service is carried out.

Some common warning signs include:

• Suspension squeaks and noises

• Clunking sounds from underneath the camper trailer

• Excessive movement in suspension components

• Uneven tyre wear

• Reduced towing stability

• Wandering or swaying while towing

• Excessive wear on suspension bolts

• Visible cracks in the bushes

• Missing bush material

• Roadworthy inspection failure

Unfortunately, suspension bushes often deteriorate gradually over several years, making the problem difficult to notice until significant damage has occurred.

Why Do MDC Suspension Bushes Fail?

One of the most common causes of suspension bush deterioration is incorrect lubrication.

Many owners and repairers unknowingly use standard workshop grease, which can cause polyurethane bushes to break down prematurely.

Polyurethane suspension bushes require specialised lubricants designed specifically for compatibility with polyurethane materials.

Using incorrect grease can cause:

• Bush swelling

• Bush softening

• Cracking

• Premature deterioration

• Increased suspension wear

In some cases, we have seen bushes fail within 12 months due to the use of petroleum-based grease.

Grease That Should Never Be Used on Polyurethane Bushes

Petroleum-Based Grease

Petroleum-based lubricants can attack polyurethane and cause rapid deterioration.
 

This is one of the leading causes of premature suspension bush failure.

Standard Lithium Grease

Although commonly used in automotive workshops, lithium grease is generally not the best choice for polyurethane suspension bushes.

It lacks the adhesion and long-term protection provided by specialised polyurethane-compatible lubricants.

Recommended Grease for MDC Suspension Bushes

For camper trailer suspension repairs and new suspension bush installations, we recommend:

Silicone-Based Grease with PTFE (Teflon)

Benefits include:

✔ Excellent water resistance

✔ Long-lasting lubrication

✔ Superior adhesion

✔ Reduced squeaking

✔ Polyurethane compatibility

✔ Improved suspension life

Specialised Polyurethane Suspension Grease

Many premium suspension manufacturers supply dedicated lubricants specifically designed for polyurethane bushes.

These products are generally the preferred option during installation.

What Happens When Suspension Bushes Are Ignored?

Many owners assume a squeaky suspension is merely an annoyance.

However, worn suspension bushes can quickly lead to more expensive problems.

Potential consequences include:

Suspension Bolt Wear

Excessive movement can wear suspension bolts and mounting hardware.

Suspension Hanger Damage

Loose suspension components can damage chassis-mounted hangers.

Uneven Tyre Wear

Poor suspension geometry can rapidly destroy expensive caravan and camper trailer tyres.

Poor Towing Characteristics

A worn suspension system can reduce towing stability and increase sway.

Roadworthy Inspection Failure

Significantly worn bushes can result in a failed roadworthy inspection.

Increased Repair Costs

Replacing bushes early is significantly cheaper than replacing bushes, bolts, hangers and tyres later.
