Applied to the CV joint, CV Joint Cage props and enables smooth rotation of the ball bearings. The CV joint cage is spherical but with ends open, and typically has six openings around the perimeter.
CV Joint Cage
CV Joint cage is a key components of CV Joint, as it is easily breakable. CV joint cage is usually made of alloys with high intensity and carburized heat treated to enhance the durability.
The rubber part of the driveshaft assembly / CV Axle is known as the CV boot, which is secured with stainless steel clamps. We call it cv boot clamp. The purpose of CV boot is to protect the internal components of the CV joint by retaining the lubricant, and also acting as a dust shied.
Tripod Joint is used at the inboard end of car driveshafts, it enables power transmission even in case of angle shifting. Tripod Joint has needle bearing / barrel-shaped rollers mounted on a three-legged spider / three-pointed yoke, instead of balls bearings. These fit into a cup with three matching grooves, attached to the differential. The rollers are mounted at 120-degrees to one another and slide back and forth in tracks in an outer “tulip” housing.
This one is a request from more than one person so I’m happy to bring it to you. As I said in the video I personally don’t see much point of replacing just the CV boots anymore as it just makes more sense to replace the axle, that’s just how I feel however. If you do want to replace the boots I hope this video will help.

Here’s how a CV Axle works to turn your car’s wheels. The constant velocity axle links the rotational motion of the transmission to the hub and thus turns the car’s wheels. Generally, CV axles are used on the front of FWD or AWD cars on vehicles with independent suspension.
The main advantage of the CV axle is that it allows for a very high degree of articulation, while still rotating its input and output shafts at the same speed. This is ideal for the front wheels which move up and down with the suspension, and turn sideways to steer.
The inner CV joint consists of a sliding tripod housing, that allows the axle to extend or contract. Inside, a carrier with needle bearings holds 3 rollers that allow for a small degree of swing.
The carrier looks like a fidget spinner. The outer CV joint does not telescope, however it has a very large degree of articulation, which is needed near the steering axis. It consists of an inner bearing race, a carrier, and the outer race or housing. the bearings are allowed to pivot about the central axis, but cannot rotate – allowing for constant rotation to be transferred from the input to output. Rubber boots cover each CV joint and are typically packed with grease.
Interestingly, the grease types appear different for each joint. Boot failure is the major cause of worn CV axles, once dirt enters the system and causes excessive wear. This axle was disassembled from a 2001 Toyota Corolla and opened up to see what’s inside and how it works.
