Rack Boots on the 2012 Holden Colorado: Purpose, Maintenance and Replacement Advice

The 2012 Holden Colorado is a solid and reliable ute that has been popular with Aussies for work and play. When it comes to steering components on this model, one commonly asked question is whether rack boots are fitted and if they require any special attention during servicing. After referencing various technical sources and workshop manuals, it turns out that the 2012 Holden Colorado does indeed utilise rack boots on its steering rack assembly. Understanding what these rack boots do and how to look after them can help keep the steering functioning smoothly and avoid costly repairs.

So what exactly are rack boots? Rack boots are flexible rubber or synthetic bellows that cover the inner tie rod and the exposed portion of the steering rack. Their main job is to protect the steering rack assembly from dirt, dust, water and debris while also keeping the steering lubricant contained inside. This protection is crucial because the steering rack is a precision component that converts the rotational movement from the steering wheel to lateral movement in the wheels.

Without rack boots, contaminants like mud and grit could enter the rack housing and cause premature wear on the internal components such as the rack gear and pinion. This wear can lead to loose steering, unusual noises, and in severe cases, complete steering failure. The boots also prevent moisture ingress which can cause rust and corrosion on metal parts. Put simply, rack boots act like a seal and dust cover to maintain the integrity and longevity of the steering system.

On the 2012 Holden Colorado, which comes with a steering rack and pinion setup, rack boots are definitely an essential part. They are usually found clamped tightly around the steering rack ends and connected to the tie rods with metal or plastic clips. These boots flex as you turn the steering wheel but remain sealed to keep out road grime and moisture. Regular maintenance checks will often involve inspecting the condition of these boots for any signs of cracks, tears or splitting.

So how should a 2012 Holden Colorado owner approach rack boot maintenance? Since the rack boots are rubber components exposed to heat, cold, water, and dirt, they can deteriorate over time. During routine servicing or wheel alignments, mechanics typically inspect the boots for damage. If they find any holes, splits or signs of perishing, those boots should be replaced immediately to avoid potential damage to the steering rack itself.

Replacing rack boots is a job that most mechanics do during routine servicing if damage is found, but it can also be tackled as a DIY project for those with some mechanical know-how. Typically, the process involves removing the wheels, disconnecting the tie rod ends, sliding off the old rack boots, cleaning the steering rack area thoroughly, lubricating the moving parts with appropriate grease, and installing new boots with fresh clamps. Proper greasing and correct fitting of the racks boots are key to ensuring long-lasting protection and smooth steering operation.

Some practical tips for 2012 Holden Colorado owners:

• Check the rack boots whenever the vehicle is serviced, or if you notice symptoms like steering looseness, noises or vibration.
• If a boot is damaged, replace it promptly to protect the expensive steering rack.
• Use parts that meet OEM specifications or are high quality aftermarket replacements to ensure the durability of the rack boots.
• Keep an eye on other steering system components when replacing rack boots, as worn tie rods or inner bushes can cause additional strain on the boots.
• Regular wheel alignments help keep steering components correctly positioned, reducing wear on the racks and rack boots.

In short, the 2012 Holden Colorado uses rack boots as an essential part of its steering system, and looking after these boots helps maintain steering precision and vehicle safety. While they may seem like a small part, failing to replace worn or damaged boots can result in expensive repairs down the road. So next time your Holden is at the mechanic, ask for a quick look over those rack boots to keep your steering sharp and your ute happy on every trip.
