    "Normal" backlash noise?

    Greetings Wayalifers,

    In this video you will hear a noise that drives me nuts. Please hear in second 7, 27, 36 and 44. Noticed it the first time when the Jeep was 2 month-old and not wheeled yet (the wife was driving it)

    https://www.youtube.com/watch?v=tlocwumJCKc

    After researched, I have come to the conclusion that this noise is caused by the infamous backlash, and please correct me if I'm wrong. My question to the experts:

    1) How much of it is considered "normal"?

    2) Can it be reduced by a mechanical fix?

    3) Will it get worst until something breaks?

    It's a manual 2012 stock. Duratracs 285/70 mounted on original wheels.

    Cheers,

    Mando.-

    1) Not normal.

    2) Not sure if what you're hearing is 'backlash.' Sounds like a bad ujoint or something to me. If it is gear backlash, whatever gearbox is doing it will have to be torn down and diagnosed.

    3) Most likely.

    If your diffs have excessive backlash, you will need to pull cover, use a dial indicator to measure, and compare with specs. Sounds more like a ujoint or something loose to me, check mounts, crossmembers, etc. You can even remove one drive shaft at a time and then re-test the vehicle and try to duplicate the noise.

    Thanks ... and some more info

    Thanks mate!

    This happens by slowly easing the clutch out at idle (no gas as shown in the video) and just as the clutch is almost fully engaged, depress the clutch pedal quickly. The Clank...clink clink is more pronounced if on an incline (due to additional charge I guess). If I depress the clutch pedal slowly...no clank, and no clank under normal driving.

    Will check all components as suggested.

    Best,

    Mando.-

    im thinking you gotta let go of that clutch budd...

    My first wheel in 10 years I had the bad habit of keeping my foot on the clutch. youre better of choking than to have the clutch worn out after 5000km (no idea how much that is in miles....im canadian....gimme a break)

    once i finally got it in my head, there was no more clank ding ding

    4low - drive it like you would an automatic. its strong enough that its going to force through your breaking

    and of course different trails or obstacles are going to bring different ways to drive but for the pass in the clip, no clutch needed. if you do come to a standstill, be soft on her, dont kick it

    Here is a video of my jeep on the rocks https://youtu.be/TRmIM6iMiwU

    I consider that normal "mechanical noise" no problem

    What's happening is you are bouncing the gears between load and coast. If you don't like the noise, don't carry any load on the drive train before clutching. Easy peasy

    Hey, that's what I'm talking about Dwiggles ... pretty common and yet not "normal" for WJCO .. and I would love to get to the bottom of it ... before I get stranded in the middle of somewhere.

    Sure didn't sound normal to me. But if Dwiggles has been dealing with it for some time and no issues, that's a good thing.

    Don't get me wrong, it's definitely not normal to me ... but wonder what that heck is it?? ... normal or not. And I've had my Jeep since Nov 2011 .. heard it first time January 2012 ... still there, nothing seems to happen.

    My manual makes the same noise when wheeling, as does every other Manual JK I have ever wheeled with. I believe I even heard it on Moby in an old video before it got swapped for the LS and associated trans.
    "It’s so hard for me to sit back here in this studio, looking at a guy out here, hollering my name!—When last year I spent more money, on spilled liquor, in bars from one side of this world to the other, than you made! You’re talking to the Rolex wearing, diamond ring wearing, kiss stealing, [WHOO!] wheelin dealin’, limousine riding, jet flying son of a gun and i'm having a hard time holding these alligators down!"

“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
