look for oil around the cam cover it leaks VIA the bolts,
182 rear shocks fail quite often look for signs of oil on the shocks.

check boot floor for damage as they crease easily,
check joins where rear quarter panels meet the tailgate frame,
watch for vague / loose steering if noticed look at track rods and rod ends and rear shocks
