Very curious on their design 'why' of that 3rd shock
The four links 'should'keep the axle assembly well enough to not need that 3rd
shock, but since they did design it in...wonder what is going on???
GM had a patent on axle snubbing with the shock mounts on the axle tube. One on
top and other bottom of the tube, or was it on opposite sides...that must be it...
on opposite sides of the axle tube to lessen axle wrap
Issue for us boy racers is that shocks have dampening rates that are different
between compression and extension.
That patent expired a long time ago
brholt...look at the pic posted by ib516 of a coil spring setup. Notice the
numbers of components that have pivot points. Precision pivot points and most
OEM's penny pinch in those pivot (precision) points sizing.
When they wear...rear alignment can become loosey goosey. Towing heavy will have
lots more wear than the grocery getter owner
Precision vs leaf spring and those main leaf end eyes with a bushing and bolt
through them. Then the shackle on the rear eye. Then the leaf stack that is
allowed to move around....some have brackets to hold them, but not tightly as
they have to stretch and contract during their functional travel
Is there a better image showing the anti-lean bar? Kinda sorta looks
like they used the axle tube as the anti-lean bar's torsion bar...
