On my 85 gmc stepside it rides realy rough like as if the shocks were busted or no good just thought id ask if any one knew why. ill drive it and the truck get real rough when riding on pavement when i hit small holes or bumps...

for the rear the truck will have shocks and ;leaf springs ----front is shocks and coils

replace the bushings and also check that all the shocks are not faulty some shocks can seem good but once installed can fail right away

You're correct friend, on replacing with heavier duty shocks. That would be a plus for your driving experience. The short wheelbase on these "Blazer" style vehicles does make for a rough ride.

I would check your tire pressure, if your running 60 psi it's going to be a bumpy ride, lower the air pressure to 35 psi and see if it makes a differance, does the truck move up and down when you jump on the bumpers or is it stiff ?

All cars have shocks and/or struts. Grand am has front struts and either rear struts or shocks. When these are worn, the ride would be rough. If a motor mount was bad, you may feel rocking or visually see the motor wiggle back and forth when you press and release the accelerator pedal. Motor mounts won't affect handling. Either shocks/struts, sway bar, stabalizer bar or links are the common cause

sounds like bad air shocks, or a leaking line, most of the time its the shock , they get rusted and dont seal that good anymore and the air slowly leaks out.

check youer air shocks for leakes and rear hight sensor

if air susp then air bag busted if not then bad shock or broken spring this isnt a senser when rideing rough/ hope this helps?

it means there is a problem with the air suspension.
