Yes I know Defenders don't come with auto as standard but quite a few people have had them converted.

If you look at the Dobinson Springs web pages it recommends not to use the Castor kit on auto Disco 1's so I assume it it would be the same for all auto's.

If its lifted & vibrating, odds on your front propshaft unis aren't happy. There are a heap of threads about this on here, Outer Limits, etc etc.

The castor correction bushes won't last long, so you'll need a permanent solution. Search on slotted hubs, cranked radius arms, & d/c shafts.

FWIW I run slotted hubs plus a d/c shaft out of a D2. Completely cures the front end geometry issues, and vibration is also cured. Now, if only the D2 shafts lasted longer...

As Max says, ANY lift on almost all Td5 Defenders resul;ts in a tailshaft vibe, and a D2 shaft will cure it. Slotting swivels above a 2" lift is also very recommended. As an aside, a castor bush correction will make the vibe worse, not better, as you are tilting the diff nose down, and the angle is even more extreme. Might make it handle well, but the shaft doesen't like it. I am firmly convinced that the 99 on defenders had different chassis jigging and therefore steering geometry, or the Td5 and R380 is on a different angle to the Tdi, as this problem is most evident in these models, not so the Tdi equipped vehicles.
