Quick reference
| Fastener | Torque (ft-lb / Nm) | Notes |
|---|---|---|
| Wheel lug nuts | 95–100 ft-lb / 129–136 Nm | Typical spec ~97 ft-lb; retorque after 25–50 miles, clean/dry studs & nuts. |
| Engine oil drain plug (5.7L 3UR‑FE) | 29–31 ft-lb / 39–42 Nm | New crush washer recommended; do not overtighten aluminum pan threads. |
| Automatic transmission drain plug (AB60) | 15–21 ft-lb / 20–28 Nm | Toyota WS fluid. Fill/inspection plug commonly 27–30 ft-lb (37–41 Nm). Verify by trans tag. |
| Front brake caliper mounting bolts | 90–125 ft-lb / 122–169 Nm | Fixed front caliper; two large anchor bolts per side. Use medium threadlocker if specified. |
| Rear brake caliper bracket bolts | 65–90 ft-lb / 88–122 Nm | Floating rear caliper bracket-to-knuckle. |
| Brake caliper slide pins (where equipped) | 20–30 ft-lb / 27–41 Nm | Rear has guide pins; front is fixed caliper (no slide pins). Use silicone brake grease on pin boots. |
| Front axle shaft (hub) nut | 170–220 ft-lb / 230–298 Nm | One-time-use staked nut; replace and stake after torque. 4WD only. |
| Spark plugs (3UR‑FE) | 13–18 ft-lb / 18–25 Nm | New crush-washer plugs installed dry; no anti‑seize. If reusing, aim low end and verify crush. |
| Valve cover bolts | 6–9 ft-lb / 8–12 Nm | Small fasteners into aluminum; tighten in stages/pattern. |
| Intake manifold – upper plenum bolts | 13–18 ft-lb / 18–24 Nm | Tighten center‑out in a crisscross sequence. |
| Intake manifold – lower to cylinder head | 20–25 ft-lb / 27–34 Nm | New gaskets recommended; torque in sequence center‑out. |
Note: Ranges are provided to cover trim/package variations and common service literature differences. Always verify by VIN in the Toyota OEM service manual.
Wheel lug torque pattern
The 2020 Tundra uses a 6‑lug hub. Tighten lug nuts in a star/cross pattern to seat the wheel evenly and prevent rotor or hub distortion:
- Number the lugs 1–6 around the circle.
- Initial pass at ~50% of final torque in a star pattern (e.g., 1‑4‑2‑5‑3‑6).
- Final pass to 95–100 ft‑lb (129–136 Nm) in the same pattern.
- Recheck torque after 25–50 miles, especially after wheel or brake service.
Brake torque notes
- Front vs. rear hardware: The Tundra’s front fixed calipers use large mounting bolts (no slide pins), while the rear floating calipers have a bracket (higher torque) and guide/slide pins (lower torque). Do not mix these values.
- Clean threads and mating faces: Remove rust and debris from the knuckle and caliper ears. Lightly wire‑brush bolt threads; do not lubricate unless Toyota specifies a threadlocker or thread sealant.
- Use the right lube in the right place: High‑temp silicone brake grease on slide pins and inside boots only. Keep grease off pad friction surfaces and rotor.
- Rotor set screws (if equipped): Snug only. These are not structural fasteners.
- Aftermarket components: Big‑brake kits or reman calipers can carry different torque values. Follow the component manufacturer if it differs from OEM.
Why torque matters
Applying the correct torque prevents fastener stretch, thread damage, and component distortion:
- Wheels: Over‑torque can stretch studs and warp brake rotors; under‑torque risks wheel loosening and stud shear.
- Engine sealing: Proper torque on the oil drain plug and valve cover prevents leaks and protects soft aluminum threads.
- Intake manifold: Even, sequenced torque avoids vacuum leaks and gasket pinch that can lead to drivability issues.
- Drivetrain: The transmission drain and axle hub nut rely on correct torque to maintain clamp load, fluid integrity, and bearing life. Always replace single‑use staked axle nuts.
Disclaimer: This guide is for general reference. Critical fasteners should be confirmed in the Toyota OEM service manual for your exact VIN, drivetrain, and option package, and updated technical service information should be consulted. When in doubt, use a calibrated torque wrench and follow the factory procedure.
