Using a car jack incorrectly is dangerous. Learn the correct jacking points for sedans, SUVs, and 4WDs to change a tire safely.
Types of Jacks
Most cars come with a Scissor Jack (compact, mechanical). 4WDs often use a Bottle Jack (hydraulic). Ensure you know which one you have.
Recommended Placement
Never jack up a car on the plastic trim or oil pan. You must find the structural jacking points:
- Unibody Cars (Sedans/Hatchbacks): Look for the "Pinch Weld". This is a reinforced metal vertical rib running under the doors. There are usually notches or arrows indicating the safe lift zones behind the front wheels and ahead of the rear wheels.
- Body-on-Frame (4WD/Utes): Place the jack directly under the chassis frame rail or the solid axle tube. Do not jack under the differential pumpkin unless the manual specifically allows it.
Situation: Soft or Uneven Ground
If you are on grass, mud, or gravel, a jack can sink or tip.
- The Fix: Place a flat, solid object under the jack base (like a thick piece of wood or a dedicated jack base plate) to spread the load.
- Warning: Never change a tire on a steep incline. If you cannot find flat ground, call for a tow.
The Golden Rule
NEVER put any part of your body under a vehicle supported only by a jack. If the hydraulic seal fails or the scissor jack slips, the car drops instantly.
