Comparison Insights:

While the Red Line grease stands out in terms of performance and longevity, it comes at a premium. For everyday drivers, the Sta-Lube or the unnamed brand offers excellent value. The choice depends on your specific needs and how demanding your driving conditions are. If you’re just greasing a CV boot during a repair, the Dorman product is fine, but for regular maintenance, consider a larger quantity of a higher performing grease.

Frequently Asked Questions (FAQs):

Q: How often should I grease my CV joints? A: This depends on your vehicle and driving habits, but generally, every 30,000-60,000 miles or as recommended in your owner’s manual is a good guideline.

Q: What happens if I don’t grease my CV joints? A: Lack of lubrication leads to premature wear and tear, eventually causing joint failure, which can result in costly repairs or even accidents.

Q: Can I use regular wheel bearing grease on my CV joints? A: While some may share similarities, CV joint grease is formulated for the specific high-stress and high-angle movements of CV joints. Using inappropriate grease can lead to premature wear and failure.

Q: How much grease should I use? A: Pack the grease until it comes out of the boot seal when the joint is fully compressed. Avoid overfilling.

Q: What’s the difference between lithium-based and synthetic greases? A: Synthetic greases generally offer better performance at extreme temperatures and have longer lifespans. Lithium-based greases are more affordable but might not perform as well in harsh conditions.

Q: Can I use a grease gun to lubricate my CV joints? A: No, most CV joints are not designed for grease gun lubrication. You should replace the grease when servicing the joint.
