🔴 Safety — Address First
~$2,479
Last done Oct 2022 @ 144,500 mi — now 170,181 mi (25,681 mi / 3.5 yrs ago).
Degraded fluid lowers boiling point and reduces stopping ability. Quoted Feb 2026 @ $199.95.
Quoted Feb 2026 (Inv #430781). Seeping — advisor noted "clean and recheck." PS loss
risk. Rack was replaced Oct 2024; hoses are original and aging.
Quoted Feb 2026 (Inv #430781). Return line replacement — includes hose + labor. Do
together with pressure hose for one labor pull.
Quoted Feb 2026 pre-work order. Affects rear stability and braking performance. Front
struts replaced Oct 2024 (Inv #392375).
🟡 Longevity — Prevent Bigger Failures
~$3,947–4,012
Quoted Feb 2026 (Inv #430781 pre-work order) — labor only estimate. Left bank cam
seal seeping. Labor intensive on V8 — requires timing cover removal. Separate job from crank seal.
Quoted Feb 2026 pre-work order. Rear main seal leak — requires transmission
removal. Separate job from camshaft seals. Address before oil loss accelerates engine wear.
Quoted May 2025 ($452.70, Inv #407123) and Feb 2026 ($516.72 pre-work order). Leaking
— separate from CV axles (both axles replaced Oct 2024). Diff fluid loss damages bearings and gears.
Toyota 7.5" clamshell bushing. Parts from East Coast Gear Supply ($172.00 + $17.19
shipping + $17.22 tax). DIY replacement.
🟣 Factory Schedule — Overdue / No Record
~$580–730
Factory due @ 150,000 mi. Now 170,181 — 20k overdue. Sequoia explicitly listed in
Toyota factory schedule. Iridium plugs recommended for V8.
Factory: 100k initial then every 50k. Due again @ 150k — now 169k. Last coolant
flush was Oct 2022 @ 144,500 mi (not at 150k). Degraded coolant corrodes water pump and cooling system.
4WD Sequoia specific — factory every 5–15k miles. No service records found
for this item across all 53 invoices. Critical for 4WD driveline longevity.
🟢 Routine Maintenance
~$343
