Frequently Asked Questions
Why do I need specific CV axles for a lifted truck?
Lifting a truck changes the geometry of the suspension, causing the CV axles to operate at steeper angles. Factory axles are not designed for these increased angles, leading to accelerated wear on the CV joints and boots, which can result in premature failure. Specialized high-angle CV axles are engineered to handle these steeper operating angles more effectively, improving durability and performance.
What is the difference between a new and remanufactured CV axle?
A new CV axle is manufactured from all-new components, ensuring fresh materials and construction. A remanufactured CV axle is an original equipment unit that has been disassembled, inspected, cleaned, and had worn components replaced with new parts. While remanufactured axles can be a cost-effective option, new axles often provide greater peace of mind regarding component integrity and longevity, especially for demanding applications like lifted trucks.
What should I look for in a high-angle CV axle?
When selecting a high-angle CV axle for a lifted truck, look for features such as high-strength chromoly steel shafts, upgraded or specialized CV joint designs that allow for greater articulation, and durable boot materials like thermoplastic or silicone that resist tearing at steep angles. A reputable brand with positive owner feedback for lifted applications is also a strong indicator of quality.
Can I install high-angle CV axles myself?
Installing CV axles can be a moderately complex task that typically requires basic automotive tools, a jack, jack stands, and potentially a torque wrench. While many mechanically inclined individuals can perform the installation, it’s crucial to follow the vehicle’s service manual or reputable online guides. If you are not comfortable with the process or lack the necessary tools, professional installation is recommended to ensure proper fitment and safety.
How often should I inspect my CV axles on a lifted truck?
For lifted trucks, especially those that see off-road use, it’s advisable to inspect your CV axles more frequently than a stock vehicle. We recommend a visual inspection of the boots for cracks, tears, or grease leaks every oil change or during any tire rotation. Listen for clicking or clunking noises during turns or acceleration, which can indicate worn CV joints. Regular inspection helps catch issues early and prevent more significant damage.
