How do I correct my driveline angles?
 

I've installed approximately 3.5"-4" of lift on my 02 Disco, and now I need to correct my front driveline angles due to my propshaft u joints being overstressed and causing vibration. My steering is a bit jittery now also. Hard to hold a straight line on the highway. Here's my question... how do I correct these angles and alleviate stress on my u joints, while also restoring control and handling characteristics? Is it as simple as replacing my radius arms with 3 or 6 degree corrected units, or is there more to it than that?

You will need castor correction arms. the catch I some of them are longer than stock and you will need a longer front shaft. When I talked to RTE he indicated a longer shaft ould be required since their arms are longer and put the font axle back to the stock location. TerraFirma will be a new d2 castor correction arms coming soon.

You can also buy castor correcting replacement bushings and install them on your radius arms.

also go to a DC rear shaft if you haven't already.

So I've heard...Does anyone know where I could find said bushings?

I have converted to a u joint style rear shaft out of a D1, if thats what you mean.

You can get them fom the UK. They are good for 1-2deg correction according to Extreme 4x4 in the UK. The hardest part is getting them pressed in the perfect orientation.

A. I feel like I need a little more than 1-2 degrees of correction.
B. Kinda pricey for some bushings.
C. Seems like it would take a certain amount of luck to get them pressed in just right.
I'd say it looks like the replacement arms might still be the better option...as long as I don't need to replace my front driveshaft.

You will have to get the radius arms. What size tires are you running? Whats angles are you at now? That will determine if you need 3 or 6

Call Justin at Lucky 8, I believe he has the bushings, I know he has the correcting radius arms. RTE also makes a mean corrected radius arm.
