I had a problem a few days ago with a horrible vibration over 40mph, found out that the front uj closest to the transfer box was completey busted and I quickly went out and bought another uj. Since then I have fitted it and have found that the prop is catching on itself because of the angle it's at. Do I need a double cardan propshaft or 3 degree radius arms?
Btw Ihave a 2 inch lift
Sorry if its been covered, I did a quick search but didn't come up with much.
 
3 degree radius arms will make the prop binding worse!
Wide angle prop or remove the lift.
 
That's why your UJ was knackered, the slop in the worn one was taking the binding away, you need a wide angle one as said above
 
Will a wide angle one be ok or a double carden one? I've heard that wide angle ones aren't very smooth to drive with
 
dont get the double carb ones they is total crap just a standard wide angled one is best up to 31 degrees if memory serves me right
 
First off, you havent searched very well! this has been done to death a million times. :(

Secondly, the above advise is all speculative.

You WILL need a double cardan if the axle input and the transfer box output are at different angles.

In order for a standard 2 UJ prop to work the input and output need to be parallel to each other. They can be on a different level but must be parallel or very very close.

If you havent used caster corrected arms with your lift then what happens is the axle rotates forward slightly changing the input angle. You need a DC prop to cure this, the extra joint corrects the angle. A wide angle wont help.

A wide angle prop is used for big lifts to stop the binding where a standard prop would catch due to a steeper angle of lift.

If you dont want to fit caster corrected arms, then get a DC prop.

My 2" lift on caster corrected arms has been fine for 2 years on a standard land rover original prop. And mine is used off road as well.

and then another truck will knock with just 2"lift, let alone correcting castor

true.

I know trewey had problems with his.

If i was the OP id get some caster corrected arms and try that. Even if you have to go down the DC route then at least the arms will be relieving the stress on the bushes. Standard non bent arms will reduce the life of those by loads.

Gwyn lewis will bend your original arms for you or i think he does an exchange service.

front radius arms
 
Ok thanks, I will look into getting my standard ones bent, for that price It won't hurt even if it doesn't work :)

exactly. ;)

Give him a call, cant fault papa G, he knows his stuff and is a nice chap to boot.
 
I bet you didn't do your brake lines, trailing arms, radius arms, bushes and breather pipes when you lifted it?
 
Brake lines, trailing arms, rear bushes and breathers have all been fitted, I have no problem on the Back just the front
