Parts for your 2013 Subaru Tribeca-Strut mounts

2013 Subaru Tribeca strut mounts — what they do and when to replace them

Based on technical sources, strut mounts are fitted to the front suspension of the 2013 Subaru Tribeca, but not the rear. The Subaru Factory Service Manual for the Tribeca identifies a front MacPherson strut design that uses an upper strut mount with an integrated bearing, while the rear is an independent multi‑link setup with separate shock absorber mounts (not “strut” mounts). This is also reflected in Subaru’s parts catalogue listings for “Front Strut Mount” and in aftermarket fitment guides from major suspension suppliers, which list front strut mounts for 2006–2014 Tribeca models.

For the front end, the strut mounts sit at the top of each MacPherson strut assembly, tying the strut to the body under the bonnet. They carry vehicle weight, isolate bumps and vibration, and let the strut rotate smoothly when steering thanks to a built‑in bearing. Good mounts keep the Tribeca quiet, stable, and predictable, especially over corrugations and rough Kiwi and Aussie roads.

They’re a wear item. Rubber hardens and cracks with age, bearings dry out, and corrosion creeps in. When they’re on the way out, drivers often notice clunks over speed humps, a creak or groan when turning the wheel at parking speeds, vague steering, or a tendency for the wheel to “stick” and not self‑centre cleanly.

• Tell‑tale symptoms: clunking or knocking, steering stiffness or “memory steer”, front‑end shimmy, and uneven tyre wear.
• Inspection tips: look for split rubber, perished isolators, rusty top plates, and rough or notchy bearing feel when the strut turns.

Best practice is to replace front strut mounts whenever front struts are replaced, or at roughly 100,000–150,000 km depending on use. If the Tribeca tows, spends time on gravel, or regularly hits big potholes, bring that forward. Always do them in axle pairs (both fronts), fit new hardware where specified, and follow safe spring‑compressor procedures. It’s smart to refresh the dust boots and bump stops at the same time. Once fitted, book a wheel alignment to keep tyres wearing evenly and the steering tracking straight.

Choosing genuine or OE‑equivalent mounts with quality bearings will keep steering light and accurate. During routine servicing, a quick check under the bonnet for torn rubber and any top‑hat movement can catch issues before they become bigger, noisier problems.

FAQs

Do all 2013 Subaru Tribecas have strut mounts?
Yes, at the front. The 2013 Tribeca uses MacPherson struts up front (with strut mounts) and a multi‑link rear without strut‑type mounts. So you’ll be replacing front strut mounts, not rear.

How long do strut mounts last on a Tribeca?
Many last 100,000–150,000 km, but harsh roads, heat, and towing can shorten that. Replace them whenever you fit new front struts, or sooner if there’s noise, binding, or play.

Can worn strut mounts cause other damage?
They can contribute to uneven tyre wear, imprecise steering, and extra stress on the struts and springs. Left too long, the knocks and binding can accelerate wear across the whole front end.
