How to Remove Lug Studs on a Jeep Liberty

Save

The lug stud on a Jeep Liberty is actually considered part of the hub-assembled wheel bearing. This is the case whether the front or rear lug stud needs to be removed. Removing is not difficult, but to reinstall one, it is recommended to draw a splined stud back into the hub plate using a pneumatic gun. Using pneumatics always makes the job easier for the would-be mechanic, but their availability are not always an option. This procedure will explain how to remove a lug stud from a Jeep Liberty, whether on a lift in the repair shop or on a jack stand in your front yard.

Things You'll Need

  • Floor jack
  • Jack stand
  • Wheel chock
  • 1/2-inch drive breaking bar
  • 1/2-inch drive socket set
  • 1/2-inch drive adjustable torque wrench
  • Rubber mallet
  • Marker or grease pencil
  • C-clamp
  • Bungee cord
  • Spray lubricant
  • Flathead screwdriver
  • Heavy-headed ball peen hammer

How to Remove Lug Studs on a Jeep Liberty

  • Park the Liberty on a level paved or concrete surface. Ensure the Liberty is in park or in gear. If you're removing a front lug stud, apply the parking brake as an added safety feature and place a wheel chock behind one of the rear tires. Do not apply the parking brake if you're replacing a rear lug stud, but place the wheel chock in front of one of the front tires.

  • Break the lug nuts loose on the wheel from which you need to remove the lug stud using the breaking bar and a socket.

  • Lift and support the wheel by using the floor jack and placing the jack stand under the axle.

  • Remove the caliper bolts using the ratchet and a socket. Pry the caliper off of the rotor with the screwdriver and support it to the frame with the bungee cord. Compress the caliper piston inward slightly (two or three turns should do it) with the C-clamp. For rear drum applications, remove the retaining rings one the lug stud(s) and strike the front end of the drum with a hammer to loosen it from the hub assembly and skip Steps 5, 6 and 7.

  • Remove the pads from the caliper anchor, and remove the caliper anchor bolts with the ratchet and a socket.

  • Establish a relationship with the studs you're not removing and the rotor by marking one tip of a stud with a grease pencil or marker and making a mark on the rotor to coincide. This way the rotor will be placed back onto the hub assembly in the same manner it was removed.

  • Remove the rotor. If the rotor is rusted or stuck to the hub, you will need to shock it off by striking it with a rubber mallet to not incur damage to the rotor. Spraying some lubricant like WD-40 around the hub face that the rotor seats over would help.

  • Strike the tip of the lug stud with force using the heavy-headed ball peen hammer. Lug studs have splines and are seated onto the hub assemblies. They are not welded or molded to the assembly. To remove them, you need to apply enough force to knock them out of their seated position in the hub. You also have to apply a high degree of caution when doing this. Take careful aim and do not strike a stud you do not wish to remove or you may damage that stud as well. Do not strike the plate of the hub assembly with the hammer or you could inflict damage to it. Careful and forceful aim with the hammer will pay off.

Tips & Warnings

  • You will need a pneumatic gun to pull in a new stud. You can try to do it by hand, but your success may be compromised. To put everything back together, reverse the order or steps. Torque the lug nuts on the tire to 100 foot-pounds using the torque wrench and a socket. Remember: If you compressed a caliper piston, pump the foot brake pedal to restore hydraulic pressure back to the piston before attempting to drive.
