prop shaft

With the lt77 on my 88'' I have a rather short prop.

Yesterday I fitted longer military/one ton shackles to help with tyre clearance and for a little more spring flex.

Now my prop is running at a nasty angle.It doesn't bind,but I can feel a slight vibration from it all the time while driving.

What should I do?

I could tilt the nose of the diff up ,to decrease the angle - but if I move it much,the two angles will be significantly different,then I suppose I will need a double cardan/cv joint.

Suggestions please.

Firstly I would have a look at the Tech here http://www.4xshaft.com/index.html

An alternative is a CV drive shaft, not a double cardan, proper Constant Velocity joints at both ends, they don't care about the different angles.

Two problems with a CV shaft; one is cost about £300, the other is not much slip joint about 3" I think.

Is this problem not one of the reasons the 90 ended up being 92.9" wheelbase?

i doubt u need a cv prop or double cardan, mine runs with lt77 and extended shackles and modded front hangers aswell and my prop runs at much more of an angle than yours, i've also done another 88 with same set up as yours with no problems, i suggest u look at the balance of your propshaft first, i take it u've already inspected uj's and splines for wear
