Frequently Asked Questions

What are the common signs that my driveshaft needs replacement?

Common signs include loud clunking noises when shifting gears, squeaking or scraping sounds (often indicating a bad U-joint), and noticeable vibration that increases with speed. If you experience these symptoms, inspect the driveshaft immediately.

How long do CV axles typically last?

CV axles are generally designed to last the life of the vehicle, but the protective rubber boots can tear, allowing dirt and moisture in. Once the boot is damaged, the joint can fail quickly. On average, expect them to last 70,000 to 150,000 miles, depending on driving conditions.

Is it difficult to install a transmission shift kit?

Installing a shift kit requires opening the transmission valve body. While many kits are designed for DIY installation, this process is complex and requires mechanical knowledge, clean working conditions, and careful attention to detail. Professional installation is often recommended.
