When you lift your suspension you alter the angle and the length of your prop-shafts. Lift it too much and you will cause excessive vibrations in the propshafts at road speeds. Also a large lift will cause the UJ's to bind. This can be solved with use of large wider yoke props for the binding and Double Cardan jointed props for the angle induced vibrations. It is often suggested to use the Discovery II front prop as this has a double cardan joint as standard...

i was about to suggest a double cardon. kill, if your running a 4.5" lift and 39's id have thought you would know what your talking about! no offence. we didnt suggest it in the 1st instance cos we didnt know your 90 was so extreme! double cardons are in the region of £250 but i have seen them go on ebay for less than a ton. keep your eyes peeled. might be worth taking a peek at the devon 4x4 forum. they have loads of advice on modded landy's.
