What are the signs of drivetrain problems on a 2026 Toyota 4RUNNER?

What should I replace at the same time?
Where labor overlaps, replace the differential or transfer-case fluid with any axle or seal job while everything is already open.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2026 Toyota 4RUNNER was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2026 Toyota 4RUNNER?
Every part on this page already fits both the 2.4L L4 ELECTRIC/GAS Turbocharged and the 2.4L L4 Turbocharged. Then a torn CV boot caught early is a cheap boot kit; caught late it is a whole axle — inspect before deciding which to buy. The notes column carries position and trim qualifiers where they apply.
