Let’s get started!

What Floor Jack and Accessories You’ll Need for Working on a Jeep Wrangler?

Before using a floor jack on your Wrangler, make sure you have the right equipment:

Floor Jack: A standard hydraulic floor jack with a rated lifting capacity of 2-3 tons is recommended for a Jeep Wrangler. You need one strong enough to lift the full weight but also small enough to fit in the tight spaces around and under your Jeep. Low-profile models are ideal. A good jack has a wide lifting saddle to spread out the load and prevent frame damage.

Jack Stands: You’ll need heavy-duty jack stands rated for at least 3 tons capacity per pair. Jack stands are essential for supporting the Jeep once lifted before going underneath. Use a matching set of the same brand/type for stability.

Wheel Chocks: Chock the wheels on the opposite end from the jacking point to prevent accidental movement. Sturdy rubber or composite chocks work well.

Gloves and Eyewear: Wear close-fitting work gloves to protect your hands when handling the jack and stands. Safety glasses help prevent eye injuries from dirt or grease.

Work Light: A portable work light comes in handy when peering into the dark underside of your Jeep. An articulating LED work light can get into tight spaces.

Repair Tools: Line up any tools, parts, and supplies needed for the service or repair beforehand. You want to spend as little time under the lifted vehicle as possible.

Finding the Proper Jacking Points on a Jeep Wrangler

The key to safe floor jack usage on a Wrangler is locating the designated lifting points on the frame or axles. Never attempt to lift a Jeep by the bumpers or body parts – this can damage the panels.

Here are the proper jacking points on a Jeep Wrangler:

• Front: The front jacking points are along the frame rail brackets just behind the front tires. Look for a dimple or notch in the frame near the transmission mount crossmember.
• Rear: The rear axle tube has a circular access cover you can remove to reveal a jack point. Use the axle tube closest to the tire you need to lift.

Consult your owner’s manual for diagrams showing the exact jack point locations recommended by Jeep. Keep the jack saddle centered on the point for stability. With the right points, you can lift either end or an entire side safely.

Step-by-Step Guide to Lifting Your Jeep Wrangler with a Floor Jack

Once you have the floor jack, stands, and other gear ready, follow these steps to lift your Wrangler properly:

Step 1) Chock the Wheels and Loosen Lug Nuts

With the Jeep parked on level, firm ground, chock the wheels furthest from the jacking point to prevent rolling. If lifting one end, chock both wheels on the opposite end.

Use your wheel lug wrench to break the lug nuts loose on the wheel(s) you’ll be lifting but don’t remove them fully yet.

Step 2) Position the Jack and Lift

Place the floor jack saddle directly under the proper jacking point. Make sure the saddle fully contacts the frame and is centered.

Pump the jack handle smoothly to raise the tire completely off the ground. Lift until there is enough room for your jack stands to fit underneath.

Step 3) Support the Jeep with Jack Stands

With the tire raised off the ground, carefully position your jack stands under the proper support points on the frame or axle. These are often behind the jack points.

Slowly turn the jack release valve to lower the Jeep until its full weight rests on the jack stands. Leave some pressure in the jack.

Step 4) Perform Service or Repairs

With the Jeep’s frame fully supported on the stands, you can now safely slide underneath on a creeper or work top-side. Examples of repairs or service requiring a floor jack include:

• Oil and filter changes
• Transmission fluid and filter service
• Transfer case and differential fluid changes
• Exhaust system removal and installation
• Brake pad, rotor, and caliper replacement
• Suspension lift, shock, and steering component installation

Use your jack to lift one corner at a time if needed for things like brake service. Take all due safety precautions. Never get under the Jeep unless it’s fully supported on stands designed for the weight. Use your work light for visibility.

Step 5) Lowering the Wrangler Back Down

Once service is complete, it’s time to lower your Jeep. Slowly crank the floor jack back up until it re-contacts the frame and takes some weight off the stands.

Carefully remove the stands and continue raising the jack until the tire touches down on the ground. Remove the jack completely once weight is resting on the suspension.

Step 6) Re-Tighten Lug Nuts and Wrap Up

Before driving away, re-tighten the lug nuts in a star pattern with your torque wrench to the factory spec. Remove wheel chocks and check that your tools and supplies are packed up.

Slowly back the Jeep off the stands and jack and you’re good to go! Be sure to dispose of any used fluids properly.

Helpful Safety Tips When Using a Floor Jack on a Jeep Wrangler

Lifting a 4,000 lb vehicle requires care and attention to safety. Here are some key tips:

• Only use a floor jack on a flat, solid, level surface with the parking brake set. Concrete is ideal, while dirt or asphalt can sink.
• Do not get any part of your body under the Jeep until it’s fully supported on properly rated jack stands. No exceptions!
• Use wheel chocks on the opposite end you are lifting to prevent inadvertent movement.
• Wear close-fitting gloves when operating the jack and stands to avoid pinched fingers or cuts.
• Stop jacking immediately if the vehicle seems unstable or the jack is struggling. Lower and reposition.
• Do not lift on trailers or inclines. Off-road recovery requires specialty jacks and procedures.
• Apply penetrating oil to rusted or stuck fasteners beforehand so parts will detach when lifted.
• Inspect jack and stands before each use. Ensure lifting points are in serviceable condition.
• Keep all tools, parts, supplies organized so you spend minimal time under the lifted Jeep.

Stay alert and work cautiously when using floor jacks and jack stands. Your safety is priority #1!

Let’s Recap How to Properly Use a Floor Jack on a Jeep Wrangler

As discussed in this comprehensive guide, here’s a quick recap of proper floor jack usage for a Jeep Wrangler:

• Select a quality 2-3 ton hydraulic floor jack and access the designated lifting points on the frame and axles.
• Chock the wheels, loosen lugs, and lift one end at a time using smooth, full pumps of the jack handle.
• Carefully position jack stands and transfer weight fully from the jack. Lift the other end similarly.
• With the Jeep properly supported, proceed with your service or repairs. Use care underneath.
• When complete, carefully lower the jack and stands in reverse order of lifting. Tighten lugs and remove chocks.

Equipped with these steps and safety tips, you can now confidently use a floor jack to lift your Jeep Wrangler and take on more DIY repair jobs and upgrades. Proper jacking technique is crucial for safely tackling projects like lift kits, engine work, off-road accessory installation, and more.

With practice, you’ll get faster at placing jack stands and lifting. But always take your time and be safe. Don’t rely solely on the jack – those sturdy stands are vital for keeping your Wrangler stable up in the air. Invest in quality equipment and use proper form each time.
