Constant velocity joint

volocity joints are to connect from the gearbox to the wheels. The inner part joins to the gearbox and the outer part is to the wheels.

The purpose of velocity joint is to transmit power through an angle at a constant speed without increase in friction or play.

by checking if its moving (smoothly or not) and any cracks or rips on rubber boots before dismantling, we can start to disassemble the joint and inspect.

Velocity joints are protected by a rubber boot from the cracks and it is usually positioned in front wheel drive.
It allows a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play.

we disassembled joint to inspect and cean it up by reading instruction. It is essential that we should follow the instruction because we might not know what should we take the part off first. first of all you need to remove the boot retaining clips to remove the boots and make sure that you put the mark on the joint and the driveshaft to put that back when you are done checking.

remove the joints from the shaft and check the outer and inner race, ball cage, rollers, circlips and grooves to know what are wrong. we have got ball cage, splines and threads were in bad condition.
