Parts for your 2018 Holden Colorado-Tie rod end

2018 Holden Colorado tie-rod-end — what it does and when to replace it

Technical sources confirm the 2018 Holden Colorado uses tie rod ends as part of its steering gear. The Holden Colorado RG Workshop Manual (Steering section) details inner and outer tie rod end inspection and replacement procedures, and GM’s Electronic Parts Catalogue lists left and right outer tie rod end assemblies for MY17–MY20 RG Colorado. Reputable aftermarket catalogues in Australia and New Zealand also range replacement tie rod ends specifically for this model, reinforcing their fitment.

On the 2018 Colorado, the outer tie rod end links the steering rack to the steering knuckle at each front wheel. It lets the wheel pivot smoothly while steering input is transferred accurately, thanks to a ball-and-socket joint protected by a rubber boot. When it’s in good nick, steering feels tight, the ute tracks straight, and tyre wear stays even.

Because most OE tie rod ends are sealed-for-life, there’s no routine greasing. However, they still live a hard life with corrugations, potholes, heavy loads, and off-road work. As part of regular servicing, a tech should check for play at the joint, torn or perished dust boots, and any looseness at the locknut. If an aftermarket greasable unit is fitted, a small top-up of quality chassis grease at service intervals is wise—just enough to slightly swell the boot without blowing it off.

• Common signs it’s time to replace: vague steering, a clunk over bumps, uneven or rapid inner/outer tyre wear, steering wheel shimmy, or a metallic knock when turning at low speed.
• Inspection tips: with the ute safely raised, grasp the tyre at 3 and 9 o’clock and feel for play, watch the joint while an assistant nudges the steering, check boots for splits and grease seepage, look for rust dust around the ball stud.

Replacement is straightforward for a trained technician: the joint is separated from the knuckle, the old outer is wound off the inner (counting turns helps preserve toe), and the new unit is torqued up with the locknut secured. Even if the turns are matched, a proper four-wheel alignment is essential afterwards to protect tyres and keep steering spot-on. If one side has failed due to wear and kilometres, it’s sensible to replace both outers together. And if there’s any free play at the inner joint, plan to renew that at the same time.

Popular questions about 2018 Holden Colorado tie rod ends

How long do tie rod ends last on a 2018 Colorado?
Service life varies with use. Many last well beyond 100,000 km on sealed roads, but frequent off-road work, big tyres, or heavy towing can shorten that. Regular checks at each service catch wear early and save tyres.

Can it be driven with a worn tie rod end?
It’s not recommended. Excess play affects steering response and braking stability, and wear can escalate quickly. If there’s noticeable clunking or wandering, it should be inspected and repaired before further driving.

Do you need an alignment after replacing a tie rod end?
Yes. Even if the new end is fitted to the same thread position, toe settings can shift. A post-repair wheel alignment keeps the Colorado tracking straight and prevents uneven tyre wear.
