Thanks for speaking up for some clarification. I actually typed in a much shorter, similar request that would have been post #2, but decided to delete it.

BTW, everyone, please note that diagrams are great, part numbers great too (for google purposes so others can find your great info months or years down the road), and also that

"rear suspension forward control arm" is far clearer than something like
"rear front control arm"

See the difference?

Also many of these arms have their own special names, such as the "guide link" there. BTW, my guide links are still truckin' along at 192+k miles.

Carry on.
