Is Your Eclipse's CV Axle Failing?
A damaged CV axle is a common issue on many front-wheel-drive cars, including the 4th generation Mitsubishi Eclipse. The most frequent cause of failure is a torn or ripped rubber boot. Once the boot is compromised, the grease that lubricates the joint escapes, and contaminants like dirt and water get in, quickly causing the joint to wear out and fail. Ignoring the symptoms can lead to a complete axle failure, which will leave your car stranded.
Key Symptoms of a Bad CV Axle:
🎬 Watch this video to identify common signs of axle failure.- Clicking or Popping Noise When Turning: This is the most classic sign of a worn outer CV joint. The noise is usually most noticeable during sharp, low-speed turns.
- Vibrations While Driving: A damaged or unbalanced axle can cause vibrations that you might feel through the steering wheel or the entire car. This vibration often gets worse as you accelerate.
- Grease on the Inside of Your Wheel: If you see a lot of thick, black grease splattered on the inner surface of your front wheels or on suspension components, it's a clear sign that a CV boot has torn.
- Clunking Sound: A clunking noise when you accelerate, decelerate, or shift gears can point to a problem with the inner CV joint.
Known Issues & Recalls
While there are no specific recalls from the National Highway Traffic Safety Administration (NHTSA) for CV axle shafts on the 2006-2012 Mitsubishi Eclipse, several other recalls exist for this generation. It's always a good practice to check if your vehicle has any open recalls. One owner of a 2006 Eclipse GT reported difficulty finding a correct-fitting aftermarket passenger-side axle with the necessary mounting bracket, suggesting a potential area for ordering mistakes. Always double-check that the new part matches the old one before installation.
Choosing an Aftermarket CV Axle
When replacing a CV axle on your Eclipse, you'll find that new aftermarket parts are widely available and are often the most cost-effective choice. It's generally recommended to replace the entire axle shaft assembly rather than just the boot 🎬 Follow this DIY tutorial to replace your 4th Gen axle. or a single joint.
Brand Quality: DSS vs. Surtrak
For the 2006-2012 Eclipse, several aftermarket brands are available. Here's an honest look at the options provided:
- DSS (Driveshaft Shop): DSS has a reputation for making high-performance axles, but they also produce standard replacement parts. Reviews are mixed. Some users have positive experiences, noting good quality and durability. Others have reported issues with vibration and difficult installation or removal on other vehicle models. For high-horsepower, modified cars, DSS is a known name, but for a standard daily driver, their OE-style replacements are a viable, if sometimes inconsistent, option.
- Surtrak / Trakmotive: Surtrak (often sold under the Trakmotive brand) is a common aftermarket choice. These are generally considered a budget-friendly option. Forum discussions suggest they are often made in China and quality can be hit-or-miss, which is a common trait for many value-priced axles. However, some owners report good results for daily driving, especially considering the lower price and lifetime warranties offered by some retailers.
Pro Tip: Many aftermarket axles, regardless of the brand on the box, are sourced from a few large manufacturers in China. The biggest difference can be the warranty and customer service from the retailer. If an aftermarket axle fails prematurely, a lifetime warranty can save you the cost of a new part, but not the labor to install it.

Frequently Asked Questions
Can I replace just the torn CV boot?
While it is possible to replace just the boot, it's a messy and time-consuming job. If the boot has been torn for a while, dirt and debris have likely already damaged the joint. For this reason, it is almost always more practical and reliable to replace the entire CV axle assembly.
Do I need to replace both CV axles at the same time?
No, you typically only need to replace the axle that has failed. However, since both axles are the same age and have been subjected to the same conditions, it's not uncommon for the other side to fail soon after. If your budget allows, replacing them in pairs can save you a future repair trip.
Is a special tool needed for the replacement?
The job requires a good set of mechanic's tools, including a 32mm socket for the axle nut, a torque wrench, and a pry bar to pop the axle out of the transmission. Some mechanics also use a slide hammer for stubborn axles. It is a DIY-feasible job for someone with intermediate mechanical experience.
