40 should be fine, I have seen that quoted for the king pin to damper upper
fulcrum, 45 for the kingpin to wishbone lower fulcrum (and 65 for the nut on
top of the trunnion). I don't think there is a figure for the inner A-arm
nuts with or without V8 bushes, I used much the same effort as for the
fulcrum nuts. Did you replace the A-arms and link bolts? Often a clonk is
caused by these moving, ovalling the holes in the A-arms and cutting through
the bolt, than the bushing in the stub axle - if it is greased properly.
