I did the Old Man Emu heavies on my 110 - approx. 3 inches of lift. I went through my suspension bushings at the time of replacement with OEM rubber bushings. I spent the next 3 to 4 month chasing vibrations. My suspension as it sits today is smooth and vibration free - consisting of Tom Woods double cardon drive shafts front and rear and Rovertym control arms front and rear.
I bought some parts from other vendors that I just couldn't get to work. After success with my Rovertym front castor correcting arms I gave them a call regarding the rear axle. They were very helpful and patient with my questions and ultimately solved my issues with a set of their adjustable arms.
The biggest mistake I made was naively accepting vendors claims that their solution would work with my 3 inch lift. I ended up ordering a Woods driveshaft for a working length that corresponded to a pair of rear arms that resulted in a driveshaft angle that wouldn't work. In the end I had to shorten the driveshaft for the new arms.
From the information I gathered on the web some get this suspension to work with minimal adjustment. Mine required everything. Regarding the castor correcting bushings - the advice I got from a few sources was stay away. The sleeve is off center in the bushing resulting in strange wear and handling.
Things are much simpler on my Series Rover.....
