front suspension parts tightened with the car's weight on them :
upper and lower control arms pivot points
sway bar mounts and end links [unless using poly pivot bushings]
strut rod forward mounts
lower shock mounts [unless using poly bushings]

rear suspension parts tightened with weight on them :
front and rear spring mounts
shock mounts [unless using poly bushings]

this will give you the longest life on these components.
