How do CV axles work?

HOW DOES A CV AXLE WORKS. Constant-velocity (CV) joints allow the drive shaft to transmit power through a variable angle, at a constant rotational speed, without a considerable increase in friction. Rear-wheel drive cars with independent rear suspensions typically use CV joints at the ends of the rear-axle half-shafts.

How do you measure a CV axle?

First, extend the axle as far as it will go by pulling on both ends of the axle. Then, measure from the outside of each cup face to get your extended measurement. Now, push the CVs together as much as you can and measure again. This is your compressed measurement.

What does CV stand for in CV axle?

Can you fix a bent axle?

In most cases a bent axle cannot be repaired and must be replaced. A bad axle will lead to other damage to your vehicle down the line. So it’s critical that the axle be in great condition to avoid other costly repairs.

Can a bent axle be straightened?

The inside diameter is the same as the stainless steel rod. With the pucks installed in the axle, you can slide the rod through the axle and see how the axle needs to be bent the opposite way to straighten it. Once the axle is in the jig, it must be bent slightly past straight, so it returns to straight.

How much does a bent axle cost?

The repairs can cost you anywhere from $170 to $900 or more. It depends primarily on the kind of car you have, as the parts will range in price quite a bit. Labor costs are typically between $100 and $200, but a few cars will cost more. It just depends on how long the mechanic has to work to change out your axle.

How bad is a bent axle?

A badly bent axle will quickly cause damage to CV joints, and it’s possible to damage your wheel hubs, bearings and other components. It can also damage the mounting flange where it attaches to the differential (in a rear-wheel drive vehicle), and possibly cause internal damage to the differential gearing.

How do you know if your axle shaft is bent?

When you’ve bent or broken an axle shaft, one of the clearest ways you’ll notice is how at lower speeds the car might seem to wobble. At higher speeds, 20 mph and up, the wobble may turn into what feels more like a general vibration.

How do you know if your CV axle is bent?

Vibrations may be accompanied by an unusual rumbling noise underneath the vehicle, strange tire wobbling, or sluggish driving and steering, which may indicate a bent axle. Vibrations may be particularly noticeable during accelerations, decelerations, or turns.

What happens if my axle breaks?

Simply stated, the axles are connected to the front wheels. If an axle begins to fail while driving, your car will start to pull to one side as one wheel loses power. When the axle breaks completely its corresponding wheel will no longer turn and although the engine may still run, the car won’t move.
