Strut Rod Bushes with Fitting Position Front Axle, Rear Axle for HSV CLUBSPORT VN

Nolathane strut rod bushes replace the worn bushes at each end of the VN CLUBSPORT front strut rod, the bar that braces the lower control arm against the chassis. Depending on the vehicle and where you?re from, the strut rod is also called a caster rod, castor rod, radius rod, tension rod or drag strut, and its bushes are often simply called caster bushes or castor bushes.

These bushes control how far the lower control arm moves backwards under braking and forwards under acceleration. When they wear, the front wheels shift in the wheel arch every time you brake, causing brake dive, wandering steering, clunks and uneven tyre wear. Polyurethane strut rod bushes hold the arm firmly in place and restore stable, predictable steering.

What a Strut Rod Does on the VN CLUBSPORT

Some front suspensions use a lower control arm with only one inner pivot. On its own, that arm would swing forwards and backwards. The strut rod runs from the outer part of the arm forward or rearward to a mount on the chassis, bracing it so the wheel stays in the correct fore-and-aft position.

Because the strut rod sets where the bottom of the wheel sits, it also sets caster, the backward tilt of the steering axis that gives the vehicle straight-line stability and self-centring steering. The bushes at each end of the rod are what keep that geometry stable while the suspension moves.

Why VN CLUBSPORT Strut Rod Bushes Matter

Under braking, the tyres try to drag the wheels rearward. The strut rod bushes resist that force. If they?re soft or worn, the lower arm moves back, which reduces caster and changes toe in the middle of a stop. That?s why worn strut rod bushes often show up as:

• The vehicle pulling to one side or darting under braking
• A clunk when braking or taking off
• Steering that feels light, vague or wanders on the highway
• Excessive brake dive at the front
• Shimmy or vibration through the steering wheel under braking
• Uneven front tyre wear
• An alignment that changes between visits

These symptoms are often blamed on brakes, tyres or steering components before the caster rod bushes are checked.

Why Strut Rod Bushes Wear Out

• Repeated braking and acceleration loads pushing the arm back and forth
• Large, soft factory rubber bushes deflecting until they tear
• Heat from the engine and brakes hardening rubber
• Oil and fluid leaks softening the rubber
• Potholes, kerb strikes and rough roads
• Performance driving with harder braking and wider, stickier tyres

On many vehicles, the chassis-end bush is a large, soft design that wears faster than other front suspension bushes, especially on high-kilometre vehicles.

Standard and Offset Strut Rod Bushes

Standard replacement strut rod bushes restore the factory geometry and remove the movement that worn rubber allows.

Offset strut rod bushes, sometimes called caster correction bushes for strut rods, move the rod?s mounting point slightly. That shifts the lower ball joint forwards or backwards and changes caster. They?re used to restore caster on vehicles where wear or a ride height change has reduced it, or to add caster on performance cars for better straight-line stability and steering weight. Each listing shows whether a kit is standard or offset and the fitting position it suits.

Caster Bushes on Passenger Cars vs 4WDs

The term ?caster bushes? means different things on different vehicles. On passenger cars with strut rod front suspension, it usually refers to the strut rod or radius rod bushes covered here. On solid front axle 4WDs, ?castor bushes? usually means offset radius arm bushes, which rotate the axle housing to correct caster after a suspension lift. They?re a different part, so confirm the suspension type on your VN CLUBSPORT before ordering.

Polyurethane vs Rubber Strut Rod Bushes

Factory strut rod bushes are often large and soft to absorb road shock and noise. That softness lets the arm move under load, and as the rubber ages, the movement increases.

Polyurethane strut rod bushes hold the lower arm firmly, so caster and toe stay where the alignment set them under braking and acceleration. Nolathane has been making polyurethane suspension bushings since 1974, originally developed to replace brass bushes in hillclimb competition. The signature red bushings are made in a range of durometers (hardness grades) for each position and offer outstanding abrasion resistance, high load-bearing capability, increased tensile strength and resistance to oil, grease, ozone and weathering.

The honest trade-off is that firmer strut rod bushes transmit a little more road shock into the cabin than soft factory rubber. Most drivers notice crisper steering, steadier braking and less dive rather than harshness.

Choosing Strut Rod Bushes for Your VN CLUBSPORT

Before ordering, confirm:

• The mounting position, chassis end or control arm end
• Whether you need standard bushes or an offset kit for caster correction
• The exact vehicle variant, as model year and body style can change the bush
• That the strut rod itself is straight and the threads at the chassis end are in good condition

Replacing the bushes on both sides at the same time keeps braking behaviour even. Our fitment guarantee means the kit you order for your VN CLUBSPORT is confirmed to suit it.

Replacing Strut Rod Bushes on Your VN CLUBSPORT

Strut rod bush replacement suits professional workshops and experienced home mechanics. As a general guide:

1. Raise the vehicle safely, support it on stands and remove the front wheel.
2. Remove the nut at the chassis end of the strut rod and unbolt the rod from the lower control arm.
3. Withdraw the rod and remove the old bushes, which may need a press or puller.
4. Clean the mounting points and inspect the rod and chassis mount for damage.
5. Fit the new bushes with a grease suitable for polyurethane, noting the orientation of any offset bushes.
6. Refit the rod, then lower the vehicle onto its wheels and tighten all fasteners to specification at ride height.
7. Have a wheel alignment (tracking) carried out to set caster, camber and toe.

Doing this job together with lower control arm bushes saves labour, as many of the same components need to be removed.
