Mitsubishi OEM Axle Boot Repair Kit Outer LH/RH for Evo X

Firstly, The Mitsubishi OEM Axle Boot Repair Kit Outer LH/RH for Evo X is a genuine Mitsubishi replacement solution for restoring the outer CV axle boot on the Mitsubishi Lancer Evolution X. Designed for the factory Evo X axle assemblies, this repair kit helps protect the outer CV joint from dirt, water, road debris and contamination while keeping the required grease contained around the joint.

For the Evo X, the correct outer boot kit depends on the axle style and vehicle build date. Mitsubishi Evo X parts suppliers identify 3817A134 for the earlier cotter-pin style axle used on 2008–2010 build-date vehicles, while 3817A182 is used for the later solid-style axle on 2010–2015 build-date vehicles. Both versions are available for left- and right-hand axle applications.

This is an important distinction when ordering an OEM CV boot because the 2010 model year includes a change in axle configuration. Always verify the build date and axle style before selecting the correct part number.

Evo X Outer CV Boot Repair Kit

The outer CV joint is located at the wheel end of the front axle and operates through steering and suspension movement while transmitting engine torque to the wheels. Its protective rubber boot is responsible for keeping lubrication inside the joint and contaminants outside.

Firstly, a properly sealed CV boot helps retain the grease required for smooth CV-joint operation.

Secondly, the boot protects the joint from water, dirt, sand and road debris that can accelerate wear.

Thirdly, replacing a damaged boot while the CV joint remains serviceable can allow the original axle assembly to be repaired instead of unnecessarily replacing the complete axle.

Genuine Mitsubishi outer boot repair kits are therefore useful for Evo X owners performing preventative maintenance, drivetrain repairs, restoration work or OEM-specification repairs.

OEM Part Numbers: 3817A134 and 3817A182

There are two applicable OEM outer boot kit numbers for the Evo X:

OEM Part Number	Axle Style	Build Date	Application
3817A134	Cotter-pin style	2008–2010	Evo X outer axle boot
3817A182	Solid style	2010–2015	Evo X outer axle boot

The supplier fitment data specifies 3817A134 for vehicles built from November 1, 2007 through September 3, 2010, and 3817A182 for vehicles built from October 1, 2010 through December 3, 2015.

Because the change occurred during the 2010 model year, using the calendar model year alone may not be sufficient. Checking the vehicle build date or existing axle configuration is recommended before ordering.

LH and RH Outer Axle Compatibility

The Evo X outer axle boot kits are designed for applicable left-hand and right-hand axle positions. Evo-specific parts listings identify the corresponding diagram positions as 32014L/32014R.

This makes the repair kit suitable for either side when the correct axle-style part number has been selected.

The kit is purchased for one axle, so if both applicable outer CV boots require replacement, two kits will generally be needed.

When to Replace an Evo X Outer CV Boot

A damaged CV boot should not be ignored. Common signs that an outer boot may require replacement include:

• Visible cracks or splits
• Grease around the axle or wheel area
• Torn or separated boot folds
• Loose or damaged boot clamps
• Grease thrown onto nearby suspension components
• Clicking or popping from a CV joint during turns

A torn boot does not automatically mean the complete CV axle must be replaced. If the CV joint has not suffered significant wear or contamination, a proper boot repair can restore its protective covering.

However, once a boot has been damaged for an extended period, the CV joint should be inspected carefully for contamination, scoring, excessive play or other signs of damage before installing a replacement boot.

Genuine Mitsubishi OEM Replacement

Using the correct genuine Mitsubishi boot kit provides an OEM-focused repair for the Evo X axle. Specialist Mitsubishi parts suppliers list these kits specifically as genuine OEM outer axle boot repair kits for the Evolution X.

This is particularly useful for Evo owners restoring their vehicle or maintaining the original drivetrain rather than replacing factory components with universal aftermarket parts.

The correct boot also needs to match the axle configuration. The change from the cotter-pin style to the solid-style axle means that selecting the correct part number is an important part of the repair.

Frequently Asked Questions

What is the Mitsubishi Evo X outer axle boot part number?

There are two applicable OEM numbers. 3817A134 is used for the earlier cotter-pin-style axle, while 3817A182 is used for the later solid-style axle.

Does the outer boot kit fit both LH and RH axles?

Yes. The Evo X outer boot repair kits are listed for both left- and right-hand applicable axle positions.

Does 3817A134 fit every 2008–2015 Evo X?

No. 3817A134 is associated with the earlier cotter-pin-style axle. Later Evo X vehicles use 3817A182 for the solid-style axle. Because the change occurred during 2010, verify the vehicle build date and axle style before ordering.

What is the difference between 3817A134 and 3817A182?

Both are outer axle boot repair kits, but they correspond to different Evo X axle designs. 3817A134 is for the earlier cotter-pin-style axle, while 3817A182 is for the later solid-style axle.

Yes, when the CV joint remains serviceable. A proper boot repair can restore protection without replacing the entire axle assembly, provided the joint has not been damaged by contamination or lack of lubrication.
