Be careful, though. While easier to do, adding the top link to the passeneger side of a driver's side drop axle has the potential for a much more drastic pinion angle when the driver's side droops and the passenger side is compressed. You won't experience this nearly as much (if at all) with the top link on the driver's side.
Thems some purdy blue knuckles you got.

Beezil said:Cresso, this isn't correct. Remember this is a discussion on radius arms, which is a completely different animal than the quad link per stock.
The axle is rigid, it does not matter where you put the upper, as long as it is strong enough to resist.
if some of you guys are having trouble visualizing the geometry and the movement, build a simple model.
the lowers position the axle underneath the vehicle to maintain wheelbase position. The tracbar keeps the axle positioned under the vehicle (left-to-right) as it pivots in an arc centered on the frame mount on a radius relative to the length of the link to its axle mount. the single upper has a simple task of keeping the axle from rotating in relation to the lower arm arc.
The lower radius arms have ONE CENTERPOINT of arc movement. This is different than the stock quad link that has TWO centerpoints of arc. the upper link on a radius set-up does not go to a different point on the 'frame'. It ties into the lower arm.
the axle CANNOT TWIST AS LONG AS ONE UPPER (OR TWO) REMAIN FIXED.
