Universal joints allow travel shafts to move along with the suspension while the shaft can be moving so power could be transmitted when the drive shaft isn’t in a direct line between the transmission and travel wheels.

Rear-wheel-drive vehicles possess universal joints (or U-joints) at both ends of the travel shaft. U-joints connect to yokes that also allow travel shafts to move fore and aft as cars go over bumps or dips in the street, which effectively shortens or lengthens the shaft.

Front-drive vehicles also work with two joints, called frequent velocity (or CV) joints, but they are a unique kind that also compensate for steering changes.

On rear-drive vehicles, one sign of a donned U-join is a “clank” sound when a drive gear is involved. On front-drive vehicles, CV joints quite often make a clicking noise when they’re put on. CV joints are covered by protective rubber boot styles, and if the shoes or boots crack or are in any other case damaged, the CV joints will eventually lose their lubrication and be harmed by dirt and moisture.
A U-joint is found in both front wheel drive and rear wheel drive cars. Although they will vary in design, they possess the same purpose of giving the drive train some U Joint china flexibility. This is necessary as all vehicles flex while in motion.

U-joints are found on each of the ends of the trunk travel shaft, whereas CV-joints are located on front wheel drive cars. Each allows the travel shaft to rotate as the differential movements in relation to the rest of drive train installed on the chassis.

The U-joint functions to save wear and tear on your vehicle’s transmission. Inability to possess a universal joint replacement done when needed can bring about substantial destruction to your car in the future.
There are several warning signs that U-joint or CV-joint is failing. They involve:
