Parts for your 2018 Holden Barina-Steering bushes

2018 Holden Barina steering-bushes — what’s actually fitted?

For the 2018 Holden Barina (TM series, GM T300 platform), “steering-bushes” aren’t a separate, serviceable part. Holden/GM Service Information (SI) and the GM Electronic Parts Catalogue for the TM Barina list no replaceable steering rack mounting bushes or column bushes for this model, the electric power steering is column-mounted, and the rack-and-pinion is rigidly fixed to the front subframe. Workshop references for the Sonic/Barina platform (e.g., Gregory’s/Haynes) outline the same setup: if the steering gear mounts or column support interfaces wear, the steering gear or column assembly is replaced as a unit rather than renewing individual bushes.

Why go bush-less? With electric power assist at the column, GM engineered the rack to be solidly mounted for precise control and consistent assist calibration. NVH (noise, vibration, harshness) isolation is handled elsewhere in the body/subframe structure and suspension. That’s why there’s no routine “steering-bushes” replacement interval on a 2018 Barina, and you won’t find a genuine part number for them.

If there’s play, clunks or vague steering on this Barina, the usual suspects sit around the steering, not in it. A good service check should look at:

• Inner and outer tie rod ends for play or torn boots
• Lower control arm bushes (especially the rear hydrobush) and ball joints
• Sway bar link rods and D-bushes
• Strut top mounts/bearings and front wheel bearings
• Intermediate steering shaft joints for any notchiness

If the steering rack itself develops movement or noise, the SI procedures call for diagnosing the gear and, where required, replacing the complete steering gear or column assembly. After any front-end work, a wheel alignment is a smart move to protect tyres and keep the Barina pointing straight. Regular inspections every service (or 10–15,000 km) will catch wear early and keep the steering feel tidy without chasing non-existent steering-bushes.

Popular questions about 2018 Holden Barina steering-bushes

Does the 2018 Barina have steering rack bushes I can replace?
No. The TM Barina’s rack is solid-mounted and the electric assist is at the column. GM’s parts listings don’t show separate rack mounting bushes, and the service procedures replace the steering gear as an assembly if needed.

What’s likely causing a steering clunk if it’s not the steering-bushes?
Most commonly it’s a worn tie rod end, a tired lower control arm rear bush, or a loose/worn sway bar link. Less often, the intermediate shaft joints or strut top mounts can cause a knock. A quick front-end inspection on a hoist will pinpoint it.

How often should the Barina’s steering get checked?
Have it inspected every service or 10–15,000 km, and always after a hard pothole hit. Any front-end repair should be followed by a wheel alignment to keep handling sharp and tyre wear even.
