Parts for your 2008 Holden Colorado-Strut mounts

2008 Holden Colorado strut mounts: are they actually used?

Short answer: no, the 2008 Holden Colorado (RC) doesn’t use strut mounts. Technical references including the Holden RC Colorado Workshop Manual (Front Suspension section), the Isuzu TFR/TFS/D‑Max Workshop Manual (2007–2012), and Gregory’s Holden Colorado & Isuzu D‑Max Service and Repair Manual all describe the front end as independent double wishbone with either torsion bars (most 4x4 and Hi‑Ride variants) or a coil/coil‑over shock arrangement on some 4x2 models, plus a separate gas shock absorber. There’s no MacPherson strut assembly in this design, so there’s no strut top bearing or “strut mount” as used on cars with struts.

Why not? A strut mount only exists on vehicles with MacPherson struts, where the strut unit carries vehicle load and doubles as a steering pivot through a bearing at the tower. The Colorado’s double wishbone layout carries load through upper and lower control arms and ball joints, while the shock absorber simply damps movement. The shock’s upper attachment is a basic bush and pin/eye mounting into the chassis, not a load‑bearing, rotating strut top. That’s why generic parts catalogues sometimes list “strut mounts” for this model, but they’re not applicable.

What should be serviced instead? For front‑end noises, vibration, or uneven tyre wear on an RC Colorado, attention should go to the parts that actually wear in this suspension type:

• Upper and lower control arm bushes and ball joints
• Shock absorbers and their upper/lower bushes
• Sway bar (stabiliser) link rods and D‑bushes
• Torsion bar anchors, bushes and ride‑height (if torsion bar equipped)
• Tie‑rod ends and wheel alignment settings

After any work that alters ride height (torsion bar adjustment, new control arm bushes, or different shocks), a proper wheel alignment is essential to protect tyres and keep it tracking straight. If the front shock upper bushes are flogged out, they’re replaced as bush kits or with new shocks, there’s no strut top bearing to renew. Using quality bushes and shocks matched to vehicle load and intended ride height is the smart way to keep an RC Colorado quiet, compliant, and predictable on Aussie and Kiwi roads.

Popular questions

Does a 2008 Holden Colorado have strut mounts?
It doesn’t. The RC Colorado runs a double wishbone front end (torsion bar or coil‑type, depending on variant) with separate shock absorbers. Because it’s not a MacPherson strut, there’s no strut top bearing or mount assembly to replace.

What should be replaced instead of strut mounts on an RC Colorado?
Typical wear items include the shock absorber bushes, shocks themselves, upper and lower control arm bushes and ball joints, sway bar links and bushes, and tie‑rod ends. After repairs, organise a wheel alignment to protect tyres and keep steering feel consistent.

I’ve got a front‑end clunk—could it be a strut mount?
On this model, clunks are more likely from worn control arm bushes or ball joints, loose or perished shock bushes, or tired sway bar links. Check ride height (torsion bar models) and alignment if the nose sits unevenly or tyres wear on the edges.
