    Hi can anyone tell me if its possible to pick up a broken cv joint or drive shaft simply by using thermal imaging?,my car was hit on the left hand front side by a large van denting the wing quite badly two days later it broke down and the the company my insurance are sending out to look at it have said that all they need to do is take some photos and thermal images to find out if the cv joint has gone and if its due to the impact from the accident?

    I have a question. My CV-Joints were replaced by the mechanic in the service center. However, I still hear the clicking sound when I make a full left turn of the wheel? I brought it back to the shop but they didn't eliminate the clicking sound. I can still hear them when i make the full left turn. Can you give me suggestion for me to say to the mechanic other options or ways to fix the problem of my car? Thanks a lot 1A Auto Parts.

    Sir my car has a bit of play on the CVT axle. The axle can be push in and outside by approx. 1cm or less and also makes knock sound while moving it. Is this a bad CVT or normal?

    Surprisingly, no leaks or damage in CVT boots and no clicking noise when turning or riding the car.

  9. Be Safe says:

    Very informative. Thanks!

  10. TX Black Belt Academy says:

    Hi, I don't hear clicking but more like a knobby tire rubbing plastic. Would that be the same as the clicking?

  11. Seb Smith says:

    what about for a rear wheel drive car? turning the wheel makes no difference?

  12. TX Black Belt Academy says:

    I have something going on with mine. I don't hear a clicking noise. I hear what sounds like a knobby tire rub. THe CV joint boot has no tears or
    cracks in it. I jacked it up and tried to shake wheel etc. no movement but when I grab the shaft it moves in an out a bit.
    Thoughts?

    I have an 04 Madza 6s and have replaced both cv axles and bearings recently. I have a grind at low speeds coming from the passenger front. I thought maybe a bad replacement axlel but when I get the car up and loosen the cv axle nut the hub wobbles a lot but only if the nut is loosened. Have the new bearings already failed in less than 90 days?

  14. Edo Ahmad says:

    Was it the same sound when stated turning the wheel to the left at 1:13?

    Please answer cuz I have that exact same sound on my car that comes after I drive the care for a while, and doesn't if the car is still cold.

    My 2012 Nissan Rogue makes noise when I’m reversing out my driver, mostly left turns. Is that an axle problem?

  17. Michael Toro says:

    Hi, i have a 99 Nissan Altima. I was testing it on an empty parking lot turning all the way to the right, where I could swear I heard a loud grinding noise. However when taking it to the mechanic, they tell me that it’s the right side cv axle, not left that needed to be replaced. Is this possible? Again, I almost sure I heard the sound coming from the left, however I’m 100% positive the noise comes when I really make those sharp right turns. Thank you for whoever answers.

  18. Bo Jay says:

    If the noise sounds on the right/passengerside of the vehicle is it the CV joint on the right that needs replacing?

  19. Edgar says:

    So let's say you do all these tests, and the car fails do you change the CV joints or the whole CV axle?

  20. Cairo M says:

    I have a 2004 nissan bluebird sylphy, the car makes a faint knocking sound from the front passengers side when i reverse. Could cv joints cause this?

  21. Balck&White s says:

    My car makes the same noise but I don't know it's from the passenger side or driver side????

  22. greg0716 says:

    vw! bet this car has under 5k on it

  23. J A says:

    What if there is a clicking/grinding noise from one side only below 10mph only going straight?

  24. Alexandra Jarrin says:

    I have a question for you.. do you have to have your windows down to hear the clicking sound? What about clicking when you turn the steering wheel wide and the clicking sounds like it's coming from the steering column?

  25. Gary Riefle says:

    I was hoping to get info on CV axel shaft side play… I heard no mention of it.

  26. john clark says:
