    Can’t get 4WD shifter into 2H

    Don't worry about that front drive shaft length, that's not causing this issue. The shaft might be a little short but I don't think it's enough to cause any issues and for sure won't affect the shifting of the transfer case. Do you have a slip yoke eliminator kit and double cardan rear shaft...

    Dana 44 driveshaft compatibility with NP231

    Yep! OP: You can either change the yoke on your axle to make it more standard or you can get a shaft made to fit what you have. Same prices and options as the normal 1310 series TJ shaft except we'll put a 1330 yoke and joint on it at the axle end. No extra wait time or cost for the "custom"...

    What front driveshaft do I need?

    Measure your Jeep, measure the distance from the transfer case yoke to pinion yoke as shown in the attached photo, that's the length drive shaft you need. Wherever you order, just make sure they know that the length you measured is the yoke to yoke or center of joint to center of joint...

    New driveshaft

    Hi, I didn't read this whole thread so forgive me if I'm missing any important details. I don't know if your Jeep is a standard TJ or a Rubicon. I'm going to assume based on the length that it is a standard TJ. The joints you need are the most common size u-joint ever made and should be...

    Front Drive Shaft Details

    Measuring is super simple, just measure the distance from your transfer case yoke to your pinion yoke as shown below. Yes, the lengths can be fairly standard but a couple minutes of your time measuring will ensure that you get the right thing the first time around. You'll hear a lot of people...

    Please help me solve the oscillating vibration crisis by providing some basic info on your Jeep

    @freedom_in_4low In theory both of your drawings would have the same results. If you have two joints at each end of those pairs of joints (each double cardan) are cancelling each other's oscillations. So joints 1 and 2 cancel each other out and joints 3 and 4 cancel each other. With the double...

    Front and rear turnkey driveshafts questions

    If you choose to rebuild your stock shafts you can find information about how to do that here https://4xshaft.com/blogs/general-tech-info-articles/diy-u-joint-replacement. Just make sure that the splines move freely but are not loose and that the other parts that are not at-home rebuildable are...

    Please help me solve the oscillating vibration crisis by providing some basic info on your Jeep

    That's right. The extra double cardan takes up more space. The shortest we can build a double-double cardan is 17.625". Most TJ rear shafts are 15"-17".

    Please help me solve the oscillating vibration crisis by providing some basic info on your Jeep

    I've been tagged so here I am. I don't have the ambition to read the whole thread and catch up on the whole conversation so forgive me if my reply is a bit out of context. Here's the thing with a double cardan shaft at each end of the shaft, it is a heavy drive shaft, there is a lot more weight...

    How does my driveshaft angle look

    Looks about right, but as others have mentioned it is hard to say from a photo. Pinion should be 1-2 degrees less than the angle of the drive shaft. Here's how you can measure. https://4xshaft.com/blogs/general-tech-info-articles/slopes-vs-angles If you are asking because you are trying to...

    Rear driveshaft Centering ball yoke

    We always use the greaseable 211355X. This is because in my opinion, when talking about the centering ball specifically, non-greaseable doesn't mean it doesn't need to be greased, it just means that you cant. Take a look at the photos below to see how the centering ball gets lubricated and...

    Front Driveshaft Issue

    I think the drive shaft was always the wrong length and the journey you embarked upon by installing the lift led you to that discovery. Put the axle where you want it in the wheel well, the drive shaft should then be made or ordered to fit. The shaft you have looks like an aftermarket shaft...

    2005 TJ Rubicon u-joint

    This is one of our shafts. The joint you need is a Spicer part number 5-213X for that end. The two joints in the double cardan are Spicer part number 5-153X. Here's some info on replacing the joint at home https://4xshaft.com/blogs/general-tech-info-articles/diy-u-joint-replacement. It's...

    In need of a little drive shaft help

    The OP did email me, and I just replied to the email. For the benefit of future readers and so that someone maybe smarter than me can weigh on my "measure the hertz" suggestion, I'll copy and paste my reply below. "I can't isolate the noise you are talking about in the video, I just hear a...

    U-Joint Play In Rear Pinion Yoke

    It's the yoke, you need to replace that yoke. It looks like one of the centering tabs is badly worn, it looks paper thin in that first picture. The joint is measuring out to the correct 1330 dimensions.
