The service manual says:
"Perform the final tightening of the rear suspension member and axle installation position (rubber bushing) under unladen condition with tires on level ground".
Does this just mean to remove the jack and tighten the nuts to spec torque with nothing significant in the back seat/deck etc? i.e. full weight of the vehicle on the suspension
(I know what the dictionary definition of 'unladen' is, but it seems a bit ambiguous since the vehicle is a load on the suspension).
