How to Check Cv Axles

To check CV axles, start by jacking up the front or rear of the vehicle and securing it with jack stands. Next, remove the wheel and inspect for any visible damage to the axle boot that could indicate a faulty joint. Then pull off both clamps from either end of the axle and slide out the entire shaft.

Once removed, look closely at all surfaces on the CV joint for signs of wear such as cracking or torn boots. If there is damage present, replace both inner and outer joints immediately. Finally, reinstall using a new C-clip if necessary before putting back on your wheel and lowering your car back onto level ground.

  • Raise Vehicle: Position the car on a set of jack stands so that you can safely examine the CV axles while they are not connected to any part of the drivetrain
  • Remove Axle Nuts: Unscrew and remove the axle nuts from both sides of each axle, using an impact wrench or socket set if necessary
  • Inspect Boots : Examine the rubber boots for signs of damage such as cracking or tearing, which would indicate that moisture has entered and caused corrosion in your CV joints over time
  • Check Grease Level : Remove each boot by pulling it off gently and inspect inside for level of grease present; make sure there is enough to properly lubricate your CV axles when reassembled
  • Feel for Play: Once all four boots have been removed from their respective axles, grab hold of one end at a time while wiggling back & forth to feel for loose play; this could be indicative of worn out bearings within each joint
  • 6 Reassemble Axles : Place new gaskets (if needed) into position before replacing all four boots onto their respective shafts & secure with original nuts/bolts before raising vehicle off jack stands

How to Diagnose a Bad CV Axle

How Do You Know If Your Cv Axle is Bad?

If your CV axle is bad, you may experience a range of different symptoms. The most common symptom will be clicking or popping noises coming from the front wheels when turning or accelerating. You might also hear scraping and grinding sounds while driving, as well as feel vibrations in the steering wheel or floorboards at certain speeds.

Additionally, if you have difficulty keeping your car straight while driving, it could be an indication that something is wrong with the CV axle. Another sign to look out for is fluid leaks near either side of the vehicle; this can indicate a broken joint inside the axle shaft assembly that needs to be replaced. Lastly, if there’s significant play in any part of your suspension system – such as excessive movement in any direction on either side of your car – then there might be a problem with one (or both) of your cv axles.

If any of these issues arise during operation then it’s important that you get them checked out by a qualified mechanic right away before further damage occurs!

What Does a Failing Cv Axle Sound Like?

A failing CV axle can often be heard before it is seen. The most common sound associated with a worn or damaged CV axle is clicking and clunking, particularly when making sharp turns or accelerating from a stop. Other sounds that may indicate an issue with the axle include grinding, humming, squeaking and rattling.

If you hear any of these noises while driving your vehicle, it’s important to have the problem inspected and repaired immediately as failure of the CV joint can lead to loss of control over your vehicle and dangerous circumstances on the road. It’s also important to note that in addition to hearing these noises when turning or accelerating, you may also experience vibration coming from your wheels which could signify an issue with one of your axles as well.

How Do I Check My Inner Cv Axle?

One of the most important components of your car is its CV axle, which helps to transfer power from the engine to the wheels. Knowing how to check your inner CV axle can help you identify any problems before they become more serious and expensive. It’s a relatively simple process that only requires a few tools and materials.

First, jack up your vehicle and remove the wheel on the side where you want to inspect the CV axle. Then, locate both ends of the shaft near each wheel hub. You should be able to see it clearly by looking through an inspection window in either end or by removing some of its protective shielding for better visibility.

Once visible, use a flashlight to look for signs of wear or damage such as cracking, splitting or fraying in either end of the joint itself or its surrounding elements like rubber boots or clips. If any are present then replace them immediately with new parts available at auto repair shops before continuing further inspections under normal driving conditions until repairs have been made correctly.

How to Check Cv Axles


How to Tell If Front Cv Axle is Bad

If your front CV axle is bad, you might notice a clicking or clunking sound coming from the area near the right and left wheels when turning. This noise could indicate that the CV joint is worn out, as well as other signs such as increased vibration while driving, difficulty in steering and a feeling of tightness around corners. If you experience any of these symptoms, it’s important to get your car inspected by a certified technician to make sure your vehicle is safe to drive.

How to Tell the Difference between Bad Wheel Bearing Bad Cv Joint

Knowing the difference between a bad wheel bearing and a bad CV joint is important for maintaining your car’s health. A bad wheel bearing will produce an audible humming noise that increases with speed, while a bad CV joint will cause clicking noises during turns or when accelerating from a stop. Additionally, excessive play in the wheels can be indicative of either issue; however, if you feel the play only when turning the steering wheel it may be due to worn-out ball joints instead of either type of bearing.

If you notice any strange sounds or movements coming from your wheels be sure to have them checked out by a professional as soon as possible!

How Much Play Should a Cv Axle Have

When it comes to CV axles, the amount of play in them is important. It should be minimal; any play greater than 0.5mm can indicate a worn axle or an issue with installation. This can lead to premature failure and could result in unsafe driving conditions, so checking your vehicle’s CV axle regularly is essential for keeping you safe on the road.


In conclusion, checking your CV axles is a relatively simple task that can save you time and money in the long run. If you suspect that one of your CV axles is failing, it’s important to take action immediately. By following the steps outlined in this blog post, you’ll be able to determine whether or not your vehicle needs new CV axles, and if so, get them replaced quickly before further damage occurs.
