Rear Prop Shaft Modification

Rear Prop Shaft Modification was created by KJS
Have had a few problems with vibrations and worn joints on my 2006 Jim. So l made a phone call to Dave Mac props and spoke with Keith. As people know the front sliding cv joint on the prop is not a serviceable item, so in discussion it was decided to modify this to a u/j set up. All the new joints including the spline are able to be greased,
and the 2 u/j's are renewable. Received the finished article this morning and very pleased.

According understand a CV joint needs to be replaced by a double-cardan u-joint

Hi Gustav, do you know the reasons why? When measured mine has more movement allowing for more articulation than the standard prop. My Jim is in standard trim with only 75 profile tyres fitted. I have run this on road and off road at the farm with no problems.

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

Take a look at
en.wikipedia.org/wiki/Constant-velocity_joint
for the reasons why.
A shaft with a UJ at each end will be fine (it is actually a double cardan shaft, but the problem is the two ends don't usually have the same angle from the main shaft), it will tend to rob power, and vibrate at large angles though, but likely you wont notice off road.

Thanks for the link, it is one l looked at before embarking on the mod. Have to say at the moment there doesn't seem to be any loss of power or vibrations, certainly a lot better than the old original. It will be interesting to see how it continues to perform over time.
