Frequently Asked Questions
Are SPL 5-3615X U-Joints better than greasable U-joints?
The SPL 5-3615X is designed for high-performance, maintenance-free operation. Non-greasable U-joints like these are often preferred for their durability and protection from contaminants, but they cannot be re-lubricated. Greasable options may require more maintenance but can sometimes last longer if properly maintained.
How do I know if my C4 Corvette needs new U-joints?
Common signs include a clunking noise during acceleration, vibrations at high speeds, and noticeable play in the driveshaft. If you experience any of these, it may be time to inspect and potentially replace the U-joints.
Can I install SPL 5-3615X U-joints myself?
If you have mechanical experience and the proper tools, you can likely install them on your own. However, given the precision required, many owners choose to have them professionally installed.
Maintenance Tips for Long-Lasting Performance
Although the SPL 5-3615X is a maintenance-free U-joint, it’s still important to regularly inspect your vehicle’s drivetrain. Here are some tips for maintaining your Corvette’s performance:
- Routine Inspections: Check the driveshaft and U-joints periodically for signs of wear or play.
