How to Rebuild a CV Axle

Summary

In this video, the creator provides a detailed, step-by-step guide to rebuilding a CV axle, focusing on a 2000 Volvo model. The video covers the necessary tools, parts, and techniques, offering tips on how to handle common issues like leaking boots and stuck parts. The creator emphasizes the importance of using high-quality rebuild kits and proper techniques to ensure durability and avoid mistakes. The process includes cleaning, inspecting parts, packing grease, and reassembling the axle. Despite specific challenges with the Volvo axle, the video offers valuable insights for anyone working on front-wheel drive cars, making it a useful resource for DIY enthusiasts.

Takeaways

• 😀 Early detection of issues in a CV axle (like a leaking inner boot) allows for rebuilding, preventing further damage.
• 😀 Rebuilding a CV axle is generally applicable to most front-wheel-drive cars, not just Volvos.
• 😀 Using high-quality parts, such as OEM or reputable suppliers like GKN or Lowbro, is recommended for durability.
• 😀 Always use brake cleaner or parts cleaner to thoroughly clean parts during disassembly to avoid contaminants.
• 😀 Certain Volvo P80 models may require grinding tabs on the cup to remove the tripod, which isn't always necessary for other vehicles.
• 😀 If the tripod doesn't come out easily, soaking the assembly overnight in brake clean or degreaser can be helpful.
• 😀 Removing the vibration dampener can be difficult; using an angle grinder is suggested if other tools fail.
• 😀 Proper packing of grease into the bearings and parts ensures longevity and smoother performance after reassembly.
• 😀 Use specific pliers for tightening CV boot clamps to avoid damaging the ear or failing to secure the boot correctly.
• 😀 Pay attention to the direction of assembly and how parts fit together (e.g., the chamfered edge of certain parts).
• 😀 Inspect all parts carefully for wear or damage before reassembling the axle to avoid future issues after installation.

Q & A

What should you do if you catch a leaking inner boot on a CV axle early enough?

If you catch it early enough, you can rebuild the CV axle. This is ideal before it starts making noise or gets damaged inside.

Why might rebuilding a CV axle not be worth it once it starts making noise?

Once a CV axle starts making noise, it's likely that something inside is damaged, making it not worth rebuilding, as repairing damaged components may not fully restore its function.

Are CV axles on different makes and models of front-wheel-drive cars similar?

Yes, CV axles on front-wheel-drive cars are very similar across the board, even if the size or specific appearance differs slightly from vehicle to vehicle.

What are the two other CV axle-related videos mentioned in the script?

The first video is about how to diagnose a warranty CV axle, and the second video discusses why the author chose to rebuild or buy a high-quality axle instead of a low-quality one.

What type of axle rebuild kit does the speaker recommend?

The speaker recommends using a high-quality OEM or supplier axle rebuild kit, such as those from GKN or Lobro, as lower-end kits can have boots that are prone to tearing and damage.

Why is it important to use the correct style of clamps when rebuilding a CV axle?

The correct style of clamps, such as CV clamp pliers, apply force more evenly around the axle, ensuring a secure fit. Regular pliers or cheaper clamps might not properly tighten and could lead to boot leaks.

What should you do before reassembling the CV axle?

Before reassembling the CV axle, make sure to thoroughly clean and inspect all the parts for wear or damage. This ensures the rebuild will be effective and prevents future problems.

Why did the speaker use a knife to cut through the vibration dampener?

The speaker used a knife to cut through the vibration dampener because it was the most practical option to remove it, as tools like a dremel or hacksaw were ineffective due to the thick metal outer portion of the dampener.

How should the bearing assembly be installed in the CV axle during reassembly?

The bearing assembly should be loaded into the housing perpendicular to its position, then spun into place. The ball bearings should be added gradually with more grease as you go.

How do you know when the CV axle assembly is properly installed onto the axle shaft?

You can feel and hear when the assembly is properly installed onto the axle shaft. The sound changes, and it feels solid when the lock ring is engaged and the assembly is no longer sliding on the shaft.
