🔧 Ball Joints - Front Lower Ball Joint Replacement

On your Tundra, the front lower ball joints are a safety-critical wear item. If you have clunking, looseness, uneven tire wear, or torn boots, replace both sides together so the front suspension stays even and safe.

Difficulty Level: Advanced | Estimated Time: 4-6 hours

⚠️ Safety & Precautions

• Park on level ground, set the parking brake, and chock the rear wheels.
• Support the truck with jack stands; never work under a vehicle held up only by a jack.
• The steering knuckle and lower control arm are heavy. Keep hands clear when separating the joint.
• If the front wheels will hang free, keep the front axle supported so the suspension does not drop suddenly.
• After reassembly, do not drive far until the alignment is checked.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the front wheel

• Use a 21mm socket and breaker bar to loosen the lug nuts.
• Lift the front of the truck with the floor jack (rated 3-ton minimum) and support it with jack stands (rated 3-ton minimum).

• Do not hammer on the stud.

Step 3: Remove the ball joint from the lower control arm

• Use a 14mm socket or the correct socket for the mounting bolts to remove the ball joint fasteners.

• Use a torque wrench to tighten the mounting bolts to factory specification.
