I don't know how many times I mentioned that I needed more slip but hey, English isn't the language used on here and I don't speak textGRPABT1 wrote:Righto righto don't get your knickers in a twist Steve, he could've said that from the start. Nice work btwGwagensteve wrote:AAAAARRRRRGGGGGHHHHH
Why can't everyone understand it's not the fawking driveshaft that's too short it's the fawking SPLINE TRAVEL that's too short.
Due to a large range of factors and geometry, even if the sierra slip was fully bottomed at full droop, it's not going to have enough spline engagement at droop.
If you plan on answering with " you need a longer driveshaft" don't bother.
This is road legal, engineered car. A square tube driveshaft isn't an option.
At the moment, there would be a very real risk the driveshaft will fall apart at full droop. That would ruin Cj's day.
That's with 100mm of spline.
I think the car needs at least 125mm of spline to have enough spline engagement at full droop to stop the shaft falling apart.
This is not related to strength.
It's not related to the length of the tube of the shaft.
It's not related to whether a double cardan shaft is used.
It's 100% a spline length issue.
If you know of a car with more than 100mm of spline, please let us know.

I had found a thread on Pirate which had also mentioned the PTO shafts and that one of the Suzuki accessoy suppliers in the USA had used them in their longer travel tail shaft.
I remeasured yesterday in all positions and hopefully I might just get away with the standard slip for now although I still have several more inches of flex available to be accessed which could push it over the edge. We'll see how we go.
Anyway this week I'll get the front and rear tail shafts extended.
