Positioning a floor jack under the rear differential provides a stable lifting point for your Jeep Wrangler JL. If you are wondering where to jack up a Jeep Wrangler JL, you need to know the exact spots that won’t damage your vehicle. This guide covers every safe lifting point for your JL, from the frame rails to the axle tubes.
Lifting a Jeep the wrong way can bend metal or crush vital components. The JL has reinforced areas designed for jacks and jack stands. You just need to find them.
This article walks you through the front and rear jack points, plus tips for using a floor jack safely. Let’s get your Jeep off the ground without any headaches.
Where To Jack Up A Jeep Wrangler Jl
The safest place to lift your entire front or rear end is the axle housing. For the front, use the center of the front axle differential. For the rear, use the center of the rear differential. These are strong, cast-iron points that can handle the weight.
Never jack directly on the axle tube itself if you can avoid it. The tube can dent or bend under concentrated pressure. Always aim for the thicker differential housing.
If you need to lift just one side, use the frame rails. The JL frame has flat, reinforced sections near each wheel. These are marked with small notches or indentations in some models.
Front Jack Points For Your Jl
The front axle differential is your primary jack point for lifting the whole front. Place the floor jack saddle directly under the center of the diff housing. Make sure the saddle is centered and stable before pumping.
For side lifts, locate the frame rail just behind the front wheel. There is a flat section about 12 inches long. Place your jack there. This area is reinforced from the factory.
- Front differential housing: Best for lifting both wheels off the ground
- Frame rail behind front wheel: Best for single-side tire changes
- Lower control arm mount: Only use if you have no other option
Some people use the lower control arm mount as a jack point. This works but it is not ideal. The mount can slip off the jack saddle if you are not careful. Stick to the diff or frame rail when possible.
Rear Jack Points For Your Jl
The rear differential is the best spot for lifting the entire rear of your JL. It is a large, sturdy casting. Place the jack saddle right under the center of the diff housing. This lifts both rear wheels evenly.
For single-side lifting in the rear, use the frame rail just ahead of the rear wheel. Again, look for the flat, reinforced section. It is usually about 10 to 12 inches long.
- Position the jack under the rear differential center
- Pump slowly until the saddle contacts the housing
- Check that the saddle is centered and not tilted
- Continue lifting until both rear tires clear the ground
- Place jack stands under the frame rail or axle tube
Never jack on the rear axle tube itself. The tube is thinner than the diff housing and can deform. Always use the differential or frame rail.
Using The Factory Scissor Jack
The factory scissor jack that came with your JL has specific lift points. These are different from floor jack points. The scissor jack is only for emergency tire changes.
Look under your Jeep for the pinch weld seam along the side. The factory jack fits into a notch in this seam. There is a small arrow or triangle marking on the body indicating the correct spot.
Do not use the scissor jack on the differential or frame rail. It is not designed for that. It will tip or slip. Only use it at the marked pinch weld points.
Where To Place Jack Stands
Never work under a vehicle supported only by a jack. Always use jack stands. The JL has dedicated jack stand points on the frame.
For the front, place jack stands under the frame rail just behind the front wheels. There is a flat, reinforced area. For the rear, place stands under the frame rail just ahead of the rear wheels.
- Front frame rail: Behind front wheel, flat section
- Rear frame rail: Ahead of rear wheel, flat section
- Axle tube near wheel: Acceptable if frame rail is not accessible
If you must use the axle tube for jack stands, place the stand as close to the wheel as possible. The tube is stronger near the wheel hub. Avoid the center of the tube.
Common Mistakes To Avoid
Many people jack up their JL in the wrong spot and cause damage. Here are the most common errors.
Jacking on the oil pan. This will crack the pan and ruin your engine. Never place a jack under the oil pan or transmission pan.
Jacking on the floor pan or body panels. These are thin sheet metal and will buckle. Only use frame or axle points.
Using a jack on uneven ground. Always park on a flat, hard surface. Soft ground or gravel can cause the jack to sink or tip.
Tools You Will Need
Having the right tools makes the job safer and easier. Here is a basic list.
- Floor jack with at least 3-ton capacity
- Pair of jack stands rated for your Jeep’s weight
- Wheel chocks to prevent rolling
- Gloves to protect your hands
- Flashlight for seeing under the vehicle
A low-profile floor jack is best for the JL. The stock ride height is not very high. A standard jack may not fit under the differential without driving onto ramps first.
If your jack does not fit, drive the front or rear wheels onto a 2×6 board. This gives you extra clearance to slide the jack under.
Step-By-Step: Lifting The Front
Follow these steps to safely lift the front of your JL.
- Park on level ground and engage the parking brake
- Place wheel chocks behind the rear tires
- Locate the front differential housing under the engine
- Position the floor jack saddle under the center of the diff
- Pump the jack until the saddle contacts the housing firmly
- Double-check that the saddle is centered and stable
- Continue pumping until both front tires leave the ground
- Slide jack stands under the front frame rails
- Lower the jack slowly onto the stands
- Shake the vehicle gently to ensure stability
Always chock the wheels that remain on the ground. This prevents the Jeep from rolling off the stands. Safety first.
Step-By-Step: Lifting The Rear
Lifting the rear is similar but has a few differences.
- Park on level ground and chock the front wheels
- Locate the rear differential housing
- Position the jack saddle under the center of the diff
- Pump slowly until the saddle contacts the housing
- Check for proper alignment and stability
- Lift until both rear tires clear the ground
- Place jack stands under the rear frame rails
- Lower the jack onto the stands
- Test stability by pushing on the bumper
If you are lifting only one side, use the frame rail on that side. Place the jack under the flat section and lift until the tire clears. Then place a stand under the same frame rail.
Lifting With A High-Lift Jack
Some off-roaders use a high-lift jack for trail repairs. This type of jack requires special attachment points on the JL.
The JL has reinforced slots in the bumpers for high-lift jacks. You can also use the aftermarket rock rails or sliders. Never use the factory side steps or plastic trim.
High-lift jacks are dangerous if you are not experienced. They can kick out or slip. Always use them on stable ground and never lift higher than necessary.
Jacking On Uneven Terrain
If you are on the trail and need to jack up your JL on uneven ground, take extra precautions.
First, try to find the flattest spot possible. Use rocks or wood planks to create a level base for the jack. Never place the jack directly on soft dirt or sand.
Second, use a wide base plate under the jack if you have one. This prevents the jack from sinking into the ground. Many off-road jacks come with a base plate for this reason.
Third, always use jack stands even on the trail. Do not rely on the jack alone. If you do not have stands, use stacked rocks or logs as a backup.
Checking Your Lift Points
Before you lift, inspect the jack points for damage. Rust, cracks, or bends can weaken the area. If you see damage, choose a different lift point.
Also check your floor jack for leaks or damage. A leaking jack can drop suddenly. Make sure the jack is in good working condition before using it.
Inspect the jack stands too. Look for cracks in the welds or bent pins. Never use damaged stands.
Jacking With A Lift Kit
If your JL has a lift kit, the jack points may be different. Some lift kits relocate the axle or add new brackets.
Check the manufacturer’s instructions for your specific lift kit. Some kits provide dedicated jack points. Others require you to use the frame or axle as usual.
Be aware that lifted Jeeps have a higher center of gravity. They are more prone to tipping when jacked. Use extra caution and wider jack stands if possible.
Frequently Asked Questions
Can I jack up my Jeep Wrangler JL on the side steps?
No. The side steps are not structural. They will bend or break. Only use frame or axle points.
Is it safe to jack on the lower control arm mount?
It is possible but not recommended. The mount can slip off the jack. Use the differential or frame rail instead.
Where do I place jack stands on a JL?
Place them under the frame rails, near the wheels. There are flat, reinforced sections designed for stands.
Can I use a floor jack on the factory pinch weld?
No. The pinch weld is only for the scissor jack. A floor jack will crush it. Use the differential or frame rail.
What if my floor jack wont fit under the differential?
Drive the wheels onto a 2×6 board to raise the vehicle slightly. Then slide the jack under. This gives you enough clearance.
Final Safety Tips
Always work on a flat, hard surface. Never jack on asphalt in hot weather, as the jack can sink. Concrete is best.
Never put any body part under the vehicle until it is supported by jack stands. A jack can fail without warning.
Use wheel chocks on the wheels that stay on the ground. This prevents the Jeep from rolling.
Double-check that the jack saddle is centered under the lift point. An off-center lift can cause the vehicle to fall.
Lower the vehicle slowly and smoothly. Do not drop it. Control the release valve on your floor jack.
If you are unsure about any step, consult your owner’s manual or a professional mechanic. It is better to ask than to risk injury.
Knowing where to jack up a Jeep Wrangler JL is a basic skill every owner should have. With the right points and proper technique, you can safely lift your Jeep for tire changes, repairs, or upgrades. Stick to the differential for full-axle lifts and the frame rails for side lifts. Use jack stands every time. Your Jeep will stay safe, and so will you.
