Universal joints question for Technic experts!

[Out of Sight]

Anyone else check this for me?

Thanks,

David.

Honestly David, I'm having trouble to pinpoint your issues. And no, a properly built boom assembly and U-joints shouldn't make a 'clicking' sound at all, despite what you'd seen in Youtube. Here's a short vid I made just to show you my 8043's u-joints in action. Both the dipper and bucket were operated simultaneously. I set the sound at max..turn up your volume, see if you can hear a single 'click'. They're very closely spaced but never touch. Ow and that U-joint alignment really works, by hearing the consistant sound of the gear whine, you'll notice I have zero vibrations too..

Problem just solved ,one of my u- joints was not fully pushed into place in the grey box beam,felt like it was pushed in but it wasn't fully it was stuck,all sorted now so thanks for the help lads,

Excellent topic, I had never done with with U-joints until 8070 so now I am learning all about them. I can see some of my MOC's where this information will be handy.

i think it could be that the UV joint was at too much of a hinge, if you rotate them and twist them too much they will either jam up or feel a little cranky depending on how steep the angle of hinging it is.
