Tightening a CV boot clamp without the specialized tool can be done, but it requires careful improvisation and an understanding of basic mechanics. It’s a temporary fix, but can prevent immediate damage; learn how to do it and its limitations.
You can effectively tighten a CV boot clamp without the dedicated tool using zip ties and pliers as a temporary solution, but this method is generally considered a short-term fix and professional repair is highly recommended.
Why Proper CV Boot Clamp Tightening Matters?
A CV joint is protected by a rubber boot that keeps lubricating grease inside and contaminants like dirt and moisture out. If the boot fails, the joint can quickly deteriorate, leading to expensive repairs or dangerous driving conditions.
The boot is sealed at both ends with clamps—usually stainless steel ‘ear-type’ bands—that must be securely crimped to form an airtight, leak-proof seal.
Factory service procedures almost always require a dedicated CV boot clamp tool—a specialized plier-like device designed to evenly compress the ears of the clamp.
But what if you don’t have one? Can you still achieve a reliable seal? Yes—but only if you apply the right method and understand the risks.
Why CV Boot Clamps Fail?
Several factors can cause CV boot clamps to fail. One common cause is corrosion. Road salt, water, and other environmental elements can corrode the metal, weakening the clamp. Another reason is simply age. Over time, the metal can fatigue and lose its clamping force.
Improper installation or overtightening can also damage the clamp. External impacts, such as hitting a pothole, can also cause the clamp to loosen or break. Regular inspection of your CV boots and clamps is important to prevent these issues.
How to tighten CV boot clamp without tool?
You can often tighten a CV boot clamp without specialized tools. Several methods work depending on the type of clamp you have. These methods leverage common tools to achieve the necessary clamping force. Let’s explore the most effective techniques.
Method 1: Using Pliers or a Wrench.
Many CV boot clamps are designed to be tightened with pliers or a wrench. These clamps usually have a small tab or a screw mechanism that allows for easy adjustment. This method is generally the simplest and most accessible.
- Inspect the Clamp: Examine the clamp to determine the tightening mechanism. Look for a tab you can bend or a screw head.
- Locate the Mechanism: Identify the part of the clamp that needs to be adjusted.
- Tighten the Clamp: Using pliers or a wrench, gently tighten the clamp. For a tab-style clamp, use pliers to bend the tab. For a screw-style clamp, use a screwdriver to turn the screw.
- Check for Tightness: Ensure the clamp is snug but not overly tight. You should not be able to easily move the boot.
Method 2: Using a Screwdriver and Leverage.
This method works well with clamps that have a slotted head. It utilizes a screwdriver to apply leverage and tighten the clamp. This technique is especially useful if you don’t have access to the correct size wrench or pliers.
- Position the Screwdriver: Place the tip of a flathead screwdriver into the slot on the clamp.
- Apply Leverage: Use the screwdriver to pry the clamp tighter. You may need to use a second tool for leverage if the clamp is difficult to move.
- Adjust and Check: Tighten the clamp until it’s snug. Be careful not to overtighten, which can damage the boot.
- Verify the Seal: After tightening, check that the boot is securely sealed.
Method 3: Alternative Clamp Designs (if Necessary).
In some cases, the original clamps may be damaged beyond repair. You might need to replace them. Consider using adjustable hose clamps. These clamps are readily available and can be tightened with a screwdriver or wrench.
- Remove Old Clamp: If the original clamp is damaged, carefully remove it using pliers or a screwdriver.
- Install New Clamp: Place the new adjustable hose clamp around the boot and joint.
- Tighten the Clamp: Use a screwdriver or wrench to tighten the clamp. Ensure it’s snug but not overly tight.
- Check for Leaks: After tightening, inspect for any signs of grease leakage.
FAQs.
Q: How do you use CV boot clamp pliers?
Once you have your boot clamp well-placed around the CV boot, grab your Lisle CV boot clamp plier and use its metal grip to hook the end of your boot clamp, then pull outward until it’s tightly fixed on the boot clamp.
After making sure it’s tight, bend the free end of the clamp over the metal clasp. Please do not apply too much effort in pulling the end of the clamp outward; this can damage the clamp.
Q: How do you attach boot clips?
For the different types of CV boot clamps found, the first one is a normal sliding saddle with a ball that holds it tight, and the other is flat, and it has to be hooked together and crush the section binding it upward to pull it tight.
Pull the clips together as tight as you can till one of the hooks enter one of the holes on the trail, further away from the raised portion, and holds the clip in place.
This can be done using your finger/thumb pressure or using a big pair of water-pump pliers. Then pinch the raised portion’s sides to compress them close together; this causes it to tighten the clip against the boot.
Q: Can you reuse the CV boots clamp?
Of course, your boot clamps can be reused. If they haven’t cracked, damaged, worn-out in the CV, or have not slid off the half-shafts, they are fit for reuse. CV boots clamp hardly ever goes bad, so there is no cause to change the clamps in most cases.
However, make sure you check the clamp thoroughly when servicing your CV axle system, so you will know if the clamps need to be changed or not.
Q: How do you replace a CV boot without removing the axle?
The axle nut in the middle of your wheel is removed instead of the whole axle so that the axle will be loosed from the steering knuckle assembly at a later point and will not interfere with the process of replacing the CV boot.
The steering wheel tie rod is also removed using a pair of simple nose pliers to remove the cotter pin. Next, the end of the threaded stud is whacked and break loose to remove it.
Disconnect the lower arm control system, the steering knuckle from the axle, and remove the old CV boot by inserting the wide end coated with grease over the axle CV joint.
Install new clips, cut away the excess CV boot materials, and reassemble all components using a reverse method.
Q: Can you use cable ties on CV boots?
A cable tie, which is also known as a hose or zip tie, or ty-rap, can be used as your CV boot clamp alternative. They are cheap and easy to use in fastening or holding items together. They prevent grease from coming out and can also be used to tighten clips.
