WHITELINE, MCA Steering Rack Coupling Bushes

Steering rack coupling bushes are replacement bushes for the steering coupling, the flexible connection between your steering shaft and the steering rack or steering box.

What Is a Steering Coupling?

When you turn the steering wheel, the movement travels down the steering column and steering shaft to the steering rack or steering box. On many vehicles, the steering shaft connects to the rack or box through a steering coupling. This coupling is sometimes called a steering coupler, a steering shaft coupling or a rag joint.

A steering coupling does two main jobs:

• It transfers steering input from the steering shaft to the rack or box.
• It provides a flexible connection, which helps absorb some vibration and accommodate small amounts of misalignment between the shaft and the rack or box.

On flexible couplings, this flexibility comes from bushes or a flexible element built into the coupling.

What Do Steering Coupling Bushes Do?

Steering coupling bushes sit inside the coupling and form part of the flexible connection between the steering shaft and the rack or box. They help:

• Connect the steering shaft to the steering rack or box
• Absorb some vibration before it reaches the steering wheel
• Allow a small amount of flex in the connection

When steering coupling bushes are in good condition, they help the steering respond as it should. When they wear, the connection can loosen, and the steering may feel different.

Types of Steering Coupling and Column Bush Kits

Fulcrum's range includes several types of kits:

• Steering coupling bush kits, which replace the bushes in the steering coupling
• Rack and pinion coupling kits, for the coupling on vehicles with rack and pinion steering
• Power steering and manual steering coupling kits, as some vehicles use different couplings depending on whether they have power or manual steering
• Steering column bush kits, which replace bushes in the steering column

If your vehicle was available with both power and manual steering, check the product listing to make sure you choose the right kit for your setup.

Steering Column Bushes

Steering column bushes support the steering shaft inside the steering column, helping it rotate smoothly and stay in position. Over time, these bushes can wear and allow movement in the column.

Fulcrum's range includes steering column bush kits for selected vehicles. They're often replaced at the same time as steering coupling bushes during steering repairs or restorations.

Signs Your Steering Coupling Bushes May Need Replacing

Steering coupling bushes move every time you turn the steering wheel, and they can wear with age and use. Worn steering coupling bushes can contribute to:

• Looseness or play in the steering wheel
• Clunking or knocking noises when turning the steering wheel
• Vibration through the steering wheel
• Bushes that are cracked, perished, torn or visibly damaged

These symptoms can also be caused by other steering or suspension components. Steering parts are critical to safety, so if you notice any change in how your steering feels, have your steering inspected by a qualified technician as soon as possible.

Steering Coupling Bushes for Older and Classic Vehicles

Many older and classic vehicles use steering couplings with replaceable bushes, and the original bushes have often worn after years of use. Steering coupling bushes and steering column bushes are common replacement items during classic car restorations and maintenance.

Replacing worn steering coupling bushes alongside other steering and suspension work helps bring the vehicle's steering back to good working order.

Choosing the Right Steering Coupling Bush Kit

Steering coupling bush kits are designed to suit particular vehicles, so choosing the right one starts with your make and model. Before you buy, check:

• Vehicle fitment: use the vehicle search to find steering coupling bushes that suit your make, model and year.
• Steering type: confirm whether your vehicle has power or manual steering, and whether it uses a steering rack or a steering box.
• The part you need: check whether you need coupling bushes, a rack and pinion coupling kit or steering column bushes.
• What's included: check the product listing to see what comes in the kit.

Full fitment details, specifications and inclusions are listed on each product page. If you can't find steering coupling bushes for your vehicle, or you're unsure which ones you need, Fulcrum's team can help.

Fitting Steering Coupling Bushes

Steering coupling bushes are part of your vehicle's steering system, so they need to be fitted correctly. Replacing them may involve disconnecting the steering shaft from the rack or box. Make sure the steering is correctly lined up when it's reassembled. If you're not confident working on steering components, have the bushes fitted by a qualified technician.
