Parts for your 2008 Subaru Tribeca-Wheel studs nuts

2008 Subaru Tribeca wheel studs and nuts

Wheel studs and nuts are absolutely used on the 2008 Subaru Tribeca. Subaru specifies a stud-and-nut arrangement rather than lug bolts on this model. This is confirmed by the 2008 Subaru Tribeca Owner’s Manual (wheels and tyres section, which calls up wheel nut torque), the Subaru Factory Service Manual procedures for wheel/hub work, and the Subaru FAST parts catalogue listings that include both wheel studs and wheel nuts for the 2008 Tribeca.

The studs are the fixed threaded posts pressed into the hub, and the nuts clamp the wheel to those studs. It’s a simple, robust setup that makes wheel changes straightforward and helps keep the wheel centred under load. For the Tribeca, Subaru specifies M12 x 1.25 threads and a wheel nut torque of about 120 N·m (88.5 ft‑lb). That torque value appears across the Owner’s Manual and FSM and should be applied in a star pattern for even clamping.

As part of routine servicing, it’s smart to check wheel studs and nuts any time wheels are off, after tyre rotations, or when chasing vibrations. Look for:

• Cross‑threading, stretched threads, or corrosion on studs and nuts
• Damaged nut seats or mismatched seat style (tapered vs flat/washer) to the wheel
• Loose, over‑tightened, or seized nuts from impact-gun abuse

Replacement and care tips for a Tribeca:

1. Always match thread size and seat style to the factory spec and the wheel design. Using the wrong nut style can crack an alloy or loosen off.
2. Install wheel nuts clean and dry—no oil, copper slip, or anti‑seize on threads unless Subaru explicitly calls for it. Lubrication changes torque‑to‑clamp load.
3. Tighten in a 5‑point star pattern to 120 N·m with a quality torque wrench. Re‑check torque after 50–100 km, especially on new wheels or after brake work.
4. If a stud is stripped, bent, or rusty, replace it. On the Tribeca that means removing the brake caliper and rotor, pressing the old stud out of the hub flange, and pulling in a new OE‑spec stud squarely.
5. Avoid rattle guns for final tightening, use them only to snug. Final torque should be by hand.

Done right, fresh studs and correctly torqued nuts keep the Tribeca’s wheels secure, stop brake pulsation caused by uneven clamping, and prevent those annoying vibrations at highway speeds.

Popular questions about 2008 Subaru Tribeca wheel studs and nuts

What is the correct wheel nut torque for a 2008 Subaru Tribeca?
Subaru specifies about 120 N·m (88.5 ft‑lb). Tighten in a star pattern and re‑check after 50–100 km. This spec is noted in the Owner’s Manual and the Factory Service Manual.

What thread size are the Tribeca’s wheel studs and nuts?
The 2008 Tribeca uses M12 x 1.25 threads. Always confirm the seat style matches your wheel (tapered or flat/washer) and avoid mixing aftermarket nut styles with factory wheels unless verified compatible.

Can a home mechanic replace a broken wheel stud on a Tribeca?
Yes, with the right tools. The brake caliper and rotor need to come off, the damaged stud is pressed out, and a new stud is pulled in squarely. Take care not to damage the hub or wheel bearing, and always torque the wheel nuts correctly after refitting.
