Hi All,

I need some prop shaft advice.

Now I know that it is important not to do DIY prop shaft welding, but I want to get everything working and in the right place before I get the prop done professionally as I may need to move the rear axle or possibly the gear box. So I thought I would do a temporary job to the prop while I get everything right.

I thought I would grind of the welds and hacksaw around the tube, but the problem is that I went to remove the old tube off the UJ and it seems to be fused to the UJ rather than welded. It looks like the tube on the UJ and the main tube are friction welded together (it is off a Sierra).

My question is, is it possible to get the tube off the UJ cleanly or not, if so how?

Thanks in advance for any help.

Get some 2" i.d. tube and cut the old prop a bit away from the u.j. then slide it inside the 2" tube and weld round it. You can cut it off then hacksaw through the tube down to the solid u.j. and finish it off with a file but it's a fiddly job. Make sure you weld the end back in the same orientation or the joint will be out of phase and vibrate badly.

......or use a 2" offcut of your existing tube as an inner sleeve. Obviously too big as it is, but hacksaw out an approx 4mm slice down its length, this allows you to close the sleeve up slightly so it's an easy hammer fit into the cut ends of the original shaft. Push it all together, leave a small (about 1mm) gap between the ends, line it all up carefully and finally top it off with a GOOD QUALITY weld.
