One of the reasons the HQ, HJ, HX, HZ and WB Holden range remains so popular today is that these cars were genuinely pleasant to drive. Compared with earlier Holdens, the HQ platform introduced improved ride quality, better road manners and more refined steering. Whether fitted with a six-cylinder engine, a 253 V8 or a 308 V8, these cars offered comfortable cruising and predictable handling that suited Australian roads perfectly.

Unfortunately, most surviving examples are now more than four decades old. Steering components that once delivered smooth, accurate control have often become worn, loose or neglected. Many owners assume that vague steering and excessive play are simply part of driving an old Holden, but the reality is quite different.

A properly rebuilt HQ-WB steering system should feel surprisingly precise and stable. If your Holden wanders on the highway, requires constant correction or feels vague around centre, chances are there are worn components that need attention.

Understanding the HQ-WB Steering System

Most HQ-WB Holdens use a recirculating ball steering box rather than the rack-and-pinion systems found in modern vehicles.

The system consists of:

• Steering box
• Pitman arm
• Idler arm
• Centre link
• Tie rod assemblies
• Steering column
• Steering couplings

Power steering became increasingly common throughout the model range, particularly on V8-powered vehicles and luxury variants.

While robust, every component in the system is now susceptible to age-related wear.

Excessive Steering Play

The most common complaint among HQ-WB owners is excessive free play in the steering wheel.

Symptoms

• Steering wheel moves before wheels respond
• Constant corrections required on highway
• Vehicle feels vague around centre
• Wandering at speed

Common Causes

• Worn steering box
• Worn idler arm
• Loose tie rod ends
• Worn steering couplings

Many vehicles suffer from several worn components simultaneously.

Worn Steering Box Problems

The steering box is often blamed first, and sometimes for good reason.

Symptoms

• Excessive free play
• Inconsistent steering feel
• Tight spots when turning
• Fluid leaks on power steering models

Causes

• Internal gear wear
• Bearing wear
• Lack of maintenance
• High mileage

Steering boxes can often be rebuilt rather than replaced.

Best Steering Box Rebuild Kit

Recommended Product: Rare Spares Steering Box Rebuild Components

Benefits

• Restores steering precision
• Retains original steering box
• Excellent parts availability

Best For

• Restorations
• Factory-correct vehicles
• General steering repairs

Idler Arm Wear

The idler arm is one of the most overlooked steering components.

Symptoms

• Wandering steering
• Excessive steering play
• Uneven tyre wear
• Front-end looseness

Why It Matters

The idler arm supports the centre link on the passenger side. Once wear develops, steering accuracy deteriorates rapidly.

Many owners replace steering boxes only to discover the idler arm was the real culprit.

Tie Rod End Wear

Tie rod ends connect steering movement to the front wheels.

Symptoms

• Steering looseness
• Clunking noises
• Uneven tyre wear
• Poor wheel alignment

Causes

• Lack of lubrication
• Age
• Road impacts

Worn tie rod ends are among the most common steering faults found during inspections.

Best Steering Rebuild Kit

Recommended Product: Rare Spares Front Steering Rebuild Kit

Benefits

• Replaces common wear items
• Improves steering accuracy
• Restores factory steering feel

Best For

• High-mileage vehicles
• Complete front-end rebuilds
• Restoration projects

Steering Coupling Failure

The flexible coupling between the steering column and steering box deteriorates with age.

Symptoms

• Excessive steering play
• Delayed steering response
• Cracking or deterioration visible

Causes

• Rubber degradation
• Oil contamination
• Age-related cracking

Replacing the coupling is often a surprisingly effective repair.

Power Steering Leaks

Power steering-equipped vehicles commonly develop fluid leaks.

Common Leak Locations

• Steering box seals
• Power steering pump
• Hoses and fittings

Symptoms

• Fluid under vehicle
• Whining pump noise
• Heavy steering
• Low fluid levels

Most leaks are repairable without replacing the entire system.

Best Power Steering Fluid

Recommended Product: Penrite Power Steering Fluid

Benefits

• Protects seals
• Reduces wear
• Suitable for classic Holden systems

Best For

• Routine servicing
• Leak prevention
• Steering system maintenance

Steering Column Issues

Steering columns can also develop wear.

Symptoms

• Steering wheel movement
• Rattles
• Excessive column play

Common Causes

• Worn bearings
• Loose mounting points
• Damaged column components

Although less common than linkage wear, column issues can contribute to poor steering feel.

Vehicle Wandering on the Highway

Highway wandering is one of the most common complaints.

Potential Causes

• Worn idler arm
• Steering box wear
• Poor wheel alignment
• Worn suspension bushes
• Incorrect tyre pressures

Steering and suspension should always be inspected together.

Steering Wheel Vibration

Symptoms

• Vibration through steering wheel
• Shaking at certain speeds
• Uneven steering feel

Possible Causes

• Wheel balance issues
• Suspension wear
• Worn tie rod ends
• Bent wheels

Not every steering problem originates in the steering system itself.

Best Upgrade for Steering Feel

Recommended Product: Nolathane Steering and Suspension Bushes

Benefits

• Reduced movement
• Improved steering response
• Better road feel

Best For

• Street cars
• Touring vehicles
• Performance builds

Many owners are surprised by how much steering precision improves after replacing worn bushes.

Wheel Alignment Matters

A perfect steering system will still perform poorly if the alignment is incorrect.

Symptoms of Poor Alignment

• Vehicle pulls left or right
• Uneven tyre wear
• Off-centre steering wheel

Always perform an alignment after steering repairs.

Power Steering Conversion Upgrades

Many base-model HQ-WB Holdens were originally fitted with manual steering.

Benefits of Power Steering Conversion

• Easier parking
• Reduced steering effort
• Improved drivability
• Better comfort

Power steering conversions remain one of the most popular upgrades for regularly driven vehicles.

Best Steering Upgrade for Daily Drivers

For most owners, the ideal steering refresh includes:

• Steering box inspection
• New idler arm
• New tie rod ends
• Steering coupling replacement
• Wheel alignment
• Suspension bush inspection

This combination often restores steering performance close to factory condition.

Common Steering Repair Mistakes

Adjusting the Steering Box First

Many owners tighten the steering box to remove play without diagnosing the true cause.

This often creates tight spots and accelerates wear.

Ignoring Suspension Components

Worn suspension bushes frequently mimic steering faults.

Replacing Only One Component

Steering systems wear as a package. Replacing one worn part often leaves other issues unresolved.

Skipping Wheel Alignment

Alignment is essential after major steering repairs.

Pre-Purchase Steering Inspection Checklist

When inspecting a HQ-WB Holden:

• Check steering free play
• Inspect idler arm movement
• Examine tie rod ends
• Look for power steering leaks
• Drive at highway speeds
• Inspect steering coupling
• Check tyre wear patterns

Steering problems are rarely difficult to identify if you know where to look.

The steering systems fitted to HQ, HJ, HX, HZ and WB Holdens were well designed and extremely durable, but time has taken its toll on most surviving examples. Excessive play, wandering, fluid leaks and worn components are now commonplace.

Fortunately, steering repairs are generally straightforward, parts remain readily available and the improvement can be dramatic. Many owners are amazed at how modern their Holden feels after a proper steering rebuild.

If your HQ-WB Holden feels vague, unstable or tiring to drive, don’t assume it’s simply because it’s old. A well-maintained steering system can transform the driving experience and make these classic Holdens safer, more enjoyable and far more rewarding to own.
