Question: I bought a U-Joint and installed it but the jack won't go down unless I release the valve all the way and then stand on it. What could be the problem?
 
Answer: The U-Joint has nothing to do with the saddle not lowering properly. You can verify this by removing the jack handle and unscrewing the U-joint further than the normal range. If the saddle stays up this verifies it has nothing to do with the U-joint. I've had the same problem; the jack's saddle not going down unless I stood on it, even with a brand new jack. My problem was the main pivot shaft was causing the sticking. The solution was grease. There is a grease fitting on mine for the main shaft but I was unable to get it to take grease. When using the grease gun, grease should squeeze out from both sides of the shaft if it's getting through completely. I took it apart and removed the shaft. I coated the shaft and the inside of the holes generously with wheel bearing grease. After I reassembled it; I worked the jack a few times and it was better but not perfect. When working it, I had to let the jack handle drop a few times until it started lowering the saddle normally. Now it works great. Another potential cause of the saddle not lowering properly could be weak return springs. But as I said, with mine it was brand new which eliminated that possibility. We recommend when replacing the U-Joint to thoroughly grease the main pivot shaft while it's apart.
 
Question: How many sides are on a hexagon? 
 
Answer: SIX. If you u-joint does not have 6 sides on it this u-joint will NOT work. At this time we don't have u-joints with a square end.
 
Question: Why is this u-joint larger in diameter than the one that came out of my jack?
 
Answer: This is the updated design which is much stronger.
 
Question: The new u-joint will not fit through the housing like my original one. How can I install it if it's too big to fit through the housing? 
 
Answer: Some dis-assembly is required to install the upgraded u-joint on some jacks that have the smaller opening in the housing. See our video that shows how to install if yours's requires partial disassembly. The job can be done in less than 15 minutes in most cases and you'll have a much stronger, beefier u-joint when finished.

    Replacement u joint

    Posted by Ollie H on 15th Dec 2016

    It is too big for my application unable to use. From Management: Unfair rating, since you either purchased this for something it's not intended for. Or, did not read description, the label information or did not watch the video. Here's what you may have missed: This is an updated design which is stronger (bigger diameter) than some of the originals. It requires some disassembly. If your model is one that is listed, it WILL fit. See the video for additional info on how the installation is carried out.

    Better than original!

    Posted by Shaun G on 27th Jul 2016

    This is a direct fit name Hein Werner u-joint. The surprising thing is that it looks MUCH better than the one that came in my jack originally. Best price I could find and was shipped in two days to my door. Thanks!

    Jack U-joint

    Posted by Richard H on 14th May 2016

    Product worked as described. Wasn't much of a floor jack without the use of the handle for operating. Product purchased and was a direct fit. Would recommend for anyone with this type of jack. Also, the u joint that this replaced appeared to be a lot lighter duty. My jack is a Hein Werner.
