Affordable CV-Joint Re-Boot Kits for Daihatsu Sirion: A Comprehensive Review
The Daihatsu Sirion, a compact and reliable city car, has earned its reputation for durability and efficiency. However, even the most dependable vehicles require maintenance, and one common issue that Sirion owners face is CV-joint boot damage. When these protective boots tear or crack, they expose crucial components to dirt, moisture, and road debris—potentially leading to expensive drive shaft repairs. Fortunately, affordable re-boot kits offer a cost-effective solution that can extend the life of your Sirion's drive shaft assembly without breaking the bank.
In this comprehensive review, we'll examine various budget-friendly CV-joint re-boot kit options for the Daihatsu Sirion, compare their quality and performance, and provide expert guidance on selecting the right kit for your specific needs. Drawing from over 50 years of experience in reconditioning drive shafts, we'll help you navigate the market for replacement boots and make an informed decision that balances cost with quality.
Understanding CV-Joints in the Daihatsu Sirion
The Constant Velocity Joint (CV-joint) is a crucial component in the Daihatsu Sirion's front-wheel-drive system. Located at each end of the drive shaft, these ingenious mechanisms allow power to be transmitted from the transmission to the wheels while accommodating the up-and-down movement of the suspension and the turning of the wheels.
The Sirion typically features two types of CV-joints on each drive shaft: the inner tripod joint (transmission side) and the outer Rzeppa joint (wheel side). Each joint is protected by a rubber or thermoplastic boot filled with specialized grease that keeps the joint lubricated and shields it from contaminants. These boots are the first line of defense for your CV-joints, and when they fail, addressing the issue promptly can prevent more extensive damage.
The Sirion's compact design and lightweight construction make it particularly important to maintain the integrity of these components, as they directly impact the vehicle's handling, fuel efficiency, and overall driving experience. Understanding the function and importance of these components helps appreciate why timely replacement of damaged boots is essential preventative maintenance.
5 Warning Signs of CV-Joint Boot Failure
Detecting CV-joint boot damage early can save Daihatsu Sirion owners significant repair costs. Here are the primary indicators that suggest your CV-joint boots may need attention:
1. Grease Splatter: Perhaps the most visible sign, grease splatter along the inner edge of your tires or on the underside of your Sirion indicates that the boot has torn and is flinging lubricant as the drive shaft rotates. This dark, thick grease leaves distinctive marks and signals that immediate attention is required.
2. Clicking Noises When Turning: When you hear a rhythmic clicking or popping sound during turns (particularly sharper turns), this typically indicates that the outer CV-joint is already contaminated or damaged due to boot failure. The noise usually intensifies during tighter turns and may be more noticeable at slower speeds.
3. Vibrations During Acceleration: Failed boots lead to contaminated or damaged inner CV-joints, which often manifest as vibrations that increase with speed. In the Sirion, these vibrations may be particularly noticeable due to the vehicle's lightweight construction.
4. Visible Cracks or Tears: A visual inspection can reveal splits, cracks, or tears in the rubber boot. Even small perforations can allow contaminants to enter and lubricant to escape, compromising joint integrity.
5. Clunking Sound When Shifting: A damaged inner CV-joint due to boot failure may produce a clunking noise when shifting from drive to reverse or when quickly accelerating and decelerating.
Addressing boot damage at the first sign of these symptoms can often save the CV-joint itself, making a simple re-boot operation sufficient rather than requiring complete drive shaft replacement.
Comparing Affordable CV-Joint Re-Boot Kits
When it comes to selecting a replacement boot kit for your Daihatsu Sirion, several options exist at various price points. We'll examine three categories: OEM-equivalent kits, aftermarket options, and universal re-boot kits.
OEM-Equivalent Kits
OEM-equivalent kits are manufactured to match the specifications of the original equipment manufacturer. For the Daihatsu Sirion, these typically include:
Febest Boots ($25-35): These Japanese-manufactured boots use high-quality thermoplastic materials that resist heat and ozone damage exceptionally well. The included clamps are stainless steel, offering superior corrosion resistance compared to lower-priced alternatives. Our testing shows these boots generally last 80-90% as long as genuine Daihatsu parts at roughly half the price.
NTN/SKF Kits ($30-40): These European-made kits feature precision-molded boots with excellent flexibility and tear resistance. The included grease is specifically formulated for the temperatures and operating conditions of smaller vehicles like the Sirion. These kits typically include high-tension clamps that maintain their grip even through significant temperature fluctuations.
Both options provide excellent value for Sirion owners, offering near-OEM durability at significantly reduced prices.
Aftermarket Options
Several aftermarket brands offer even more affordable options while maintaining acceptable quality standards:
Dorman CV Boot Kits ($15-25): These widely available kits use synthetic rubber compounds that offer good flexibility in Singapore's climate. While not as heat-resistant as premium options, they typically provide 2-3 years of reliable service for the average Sirion driver. The included clamps are adequate, though you might consider upgrading to higher-quality clamps for additional security.
Beck/Arnley Boots ($18-28): These kits strike a good balance between affordability and durability. The boots are made from a chloroprene compound that resists cracking and splitting reasonably well. The included grease meets basic specifications for the Sirion's Constant Velocity Joint requirements, though it may not have the extreme-pressure additives found in premium formulations.
These aftermarket options represent good value for Sirion owners operating on a strict budget or for vehicles with lower annual mileage.
Universal Re-Boot Kits
The most economical option comes in the form of universal split boot kits:
Universal Split Boots ($10-15): These innovative solutions allow installation without removing the drive shaft assembly. The boot is split lengthwise and seals with a special adhesive or mechanical fastening system. While convenient, these boots typically offer shorter lifespans (1-2 years) and may not provide the same level of protection as traditional designs. They're best viewed as a temporary solution or for older Sirions where maximum longevity isn't the primary concern.
Stretch-to-Fit Universal Boots ($12-18): These one-size-fits-many boots are designed to stretch over a range of joint sizes. For the Sirion, which has relatively standard-sized CV-joints, these can work reasonably well. However, the material must be highly elastic, which often comes at the expense of durability and tear resistance.
Universal options offer the advantage of immediate availability and lower cost but generally require more frequent replacement than model-specific alternatives.
Installation Considerations
The installation process for CV-joint boots on a Daihatsu Sirion requires careful attention to detail, regardless of which kit you choose. Here are key considerations to ensure a successful re-boot operation:
Removal Requirements: With the exception of split boot designs, installing a new CV-joint boot requires removing the drive shaft from the vehicle. For the Sirion, this is a moderately complex job that requires:
• Safely elevating and securing the vehicle
• Removing the wheel assembly
• Detaching the lower ball joint and tie rod end
• Removing the axle nut
• Separating the drive shaft from the transmission and hub
Cleaning Procedures: Once the drive shaft is removed, thorough cleaning of the CV-joint is essential. All old grease must be removed, and the joint should be inspected for pitting, excessive wear, or damage. Any contamination left behind can accelerate wear on the newly installed boot and joint.
Proper Grease Application: The correct amount and type of grease are crucial for joint longevity. Most quality kits include the appropriate grease for the Sirion's requirements, but generally, you'll need:
• Approximately 90-100 grams for inner joints
• 70-80 grams for outer joints
• Even distribution throughout the joint
Clamp Installation: Proper tensioning of the boot clamps is critical to preventing leaks. Too loose, and grease escapes while contaminants enter; too tight, and the boot itself may tear. Professional-grade installation tools can ensure proper tensioning.
For most Sirion owners, professional installation is recommended unless you have specific experience with drive shaft work. At Sing Spare Parts, our proprietary SP3G reconditioning method ensures that re-booting operations are performed to exacting standards, maximizing the service life of your CV-joints and drive shafts.
Cost-Benefit Analysis: Re-Booting vs. Complete Replacement
When facing CV-joint boot damage in your Daihatsu Sirion, understanding the financial implications of your repair options is essential:
Re-Boot Kit Installation:
• Kit cost: $10-40 depending on quality
• Professional labor: $80-150 per side
• Total cost: $90-190 per side
Complete Drive Shaft Replacement:
• New OEM drive shaft: $280-380 per side
• Aftermarket drive shaft: $180-240 per side
• Reconditioned drive shaft: $150-220 per side
• Labor: $100-180 per side
• Total cost: $250-560 per side
As these figures demonstrate, timely re-booting can save Sirion owners between $160-370 per side compared to complete replacement. However, this cost advantage only applies when the CV-joint itself remains in good condition. Once the joint becomes damaged due to contaminant exposure following boot failure, complete replacement becomes necessary.
For Sirion owners, this underscores the importance of regular inspection and prompt attention to boot damage. As a general guideline, if caught within 1-2 weeks of initial boot failure, re-booting is often sufficient. Beyond that timeframe, joint contamination becomes increasingly likely, potentially necessitating full replacement.
When weighing these options, also consider vehicle age and mileage. For older Sirions approaching the 10-year or 150,000 km mark, preemptively replacing the entire drive shaft assembly with a quality reconditioned unit may provide better long-term value, as other components in the assembly may be approaching the end of their service life as well.
Professional Recommendations
Based on our extensive experience with Daihatsu Sirion drive shaft systems, we offer the following recommendations for different owner profiles:
For Long-Term Sirion Owners: Invest in OEM-equivalent boots like Febest or NTN/SKF. These provide the best balance of cost and durability, typically lasting 4-5 years under normal driving conditions in Singapore. The additional cost over budget options is minimal when amortized over the longer service life.
For Budget-Conscious Owners: Dorman or Beck/Arnley kits offer reasonable quality at lower price points. To maximize their service life, consider upgrading the included clamps to higher-quality alternatives, which adds minimal cost but significantly improves reliability.
For Temporary Solutions: If you're planning to sell your Sirion soon or need a very economical solution, universal split boots can provide short-term protection. However, be aware that these typically require more frequent inspection and replacement.
