Bellow Clamp For CV Boot, 34MM.
The Porsche Bellow Clamp for CV Boot is a genuine OEM clamp designed to secure the constant velocity (CV) joint boot in place. This heavy-duty band keeps the rubber boot tightly sealed to the driveshaft and flange, ensuring that vital CV joint grease stays inside while dirt, water, and debris stay out.

What This Product Does:

The clamp fastens the rubber or neoprene CV boot onto the shaft and/or housing flange, sealing it in place so the boot remains tight and doesn’t slip.
It helps keep grease inside the CV joint (lubricating the joint) and prevents dirt, water, debris from penetrating the boot and damaging the joint.
Ensures the boot stays under the correct tension so it doesn’t collapse or leak under motion or load.

Symptoms / Signs Of Failure:

• Grease leaking out of the CV boot, leading to a messy axle or splattered grease near the joint.
  
• CV boot collapse or deformation — when not secured, the boot may shift or fold.
  
• Ingress of dirt, water or debris into the CV joint, leading to accelerated wear, pitting, or noise.
  
• Clicking, popping, or humming noises under load or while turning, caused by a failing CV joint.
  
• Loose or slipping boot edges, or visible gaps between the boot and flange.

Why Replacement Matters:

• Protects the CV joint’s longevity — by keeping grease in and contaminants out, the joint lasts far longer.
  
• Prevents costly drivetrain repairs — a damaged CV joint is expensive; a failed boot clamp is cheap.
  
• Maintains proper boot tension and seal so the boot doesn’t move, stretch, or fail prematurely.
  
• Ensures consistent, quiet performance — a well-sealed boot helps avoid noise from a damaged joint.
