How many drivetrain parts fit the 2021 Jeep Gladiator?

Our catalog currently lists 180 drivetrain parts for the 2021 Jeep Gladiator across 46 subcategories and 19 brands, covering both the 3.0L V6 DIESEL Turbocharged and the 3.6L V6. Each part is matched to the engine(s) it fits.

Do drivetrain parts differ between 2021 Jeep Gladiator engines?

Some do. 159 parts fit every engine; the other 21 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What are the signs of drivetrain problems on a 2021 Jeep Gladiator?

Common symptoms include clicking in tight turns, a clunk when shifting between drive and reverse, vibration that builds with speed, or gear oil on the inside of a wheel. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

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 2021 Jeep Gladiator 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 2021 Jeep Gladiator?

First match the engine — each row shows which engine(s) the part fits. 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.

This table covers the actuators that engage four-wheel drive at the transfer case or axle. Typical signs include a door or range that will not move, or a click with no motion. Confirm the command signal before replacing the actuator — a failed module looks the same.
