One of the most misunderstood things I've
run into in all my years of drive train is
understanding DRIVESHAFT angle and what
it's effects are on a vehicle.
I will try to make this as simple as possible
As a DRIVESHAFT turns at given angle the joint
moves in an forward to back motion the first spot
is the trans.angle and the second is the shaft
this movement kind of makes a x on paper if you were
to map it out.
Quite simply if the x or angle measurement on
the top isn't the same on the bottom you will end
up with a bicycle crank type of movement. In other words one movement will not counteract the other
movement.

look at the chart below

The picture above shows a simple driveline and how its angles are laid out.this is a text book lay out and if you can achieve angles like this please do. But remember its not a perfect world and there are different factors to deal with when building a car,With all the vehicle's I have been under it
never ceases to amaze me me what should work
doesn't and what should not work does. The point
i'm trying to make is get the angles as close as
possible and if there is a problem after it can
be taken care of at that time.If you have a vehicle that has a problem and don't know what to do contact us and we will help you as much as we can.
