The Toyota 4Runner is a renowned SUV for its ruggedness and off-road capabilities. However, even the toughest vehicles require regular maintenance, and one common issue that 4Runner owners may encounter is a torn CV boot. This can lead to grease leaking out, exposing the CV joint to dirt and debris, which can eventually cause damage and costly repairs.

If you’re looking to tackle this repair yourself, this guide will provide you with a comprehensive step-by-step process on how to replace CV boot Toyota 4Runner.

Understanding CV Boots and Their Importance

Before diving into the repair process, it’s essential to understand the function of CV boots and their importance in your 4Runner’s drivetrain.

CV boots, also known as Constant Velocity boots, are rubber coverings that protect the CV joints, which are responsible for transmitting power from the transmission to the wheels. These joints allow the wheels to turn freely while maintaining a constant speed, even when the vehicle is turning.

The CV boot acts as a seal, preventing dirt, water, and other contaminants from entering the CV joint. When a CV boot tears, it compromises this seal, allowing contaminants to enter and damage the CV joint. This can lead to a clicking or popping sound when turning, especially at low speeds. In severe cases, a torn CV boot can cause the CV joint to fail completely, resulting in a loss of power to the wheels.

Here are some telltale signs that your 4Runner’s CV boot may need replacing:

• Visible tears or cracks in the boot: This is the most obvious sign of a damaged boot.
• Grease or oil leaking from the boot: This indicates that the seal is compromised and contaminants are entering the CV joint.
• Clicking or popping sounds when turning: This is a sign that the CV joint is damaged and may be caused by debris entering the joint.
