The 2001 Chevrolet suburban does not have suspension lubrication points. The squeaking noises you hear is an indication of the shocks needing replacement.
This is probably caused by a worn or poorly lubricated suspension part such as an idler arm, strut or stabalizer bar. If you have not had a chassis lubrication lately, have a technician check it out. Today very few chassis parts require lubrication, and some cheapie oil changes no longer include a lube, even though they still call it an LOB - lube, oil and filter.
Sounds like your suspension joints are dry or worn out.
If it squeaks while it moves but not while it's at idle then the squeaks are body or suspension noise.
It maybe your suspension that squeaks when ever you go over the speed bumps.
put vasalin or oil on it then take it to a workshop if that doesnt help.
No one cares!
The positional sensor can produce squeaking in a car. The shocks can also cause squeaking in a suspension system of a car as well. Springs under the engine are known for this, too.
BREAKScheck your break pad or also could be rotors.most likely the rubber bushings are too dry on the suspension components

check your power steering fluid
Press on all four corners of the car. Look for how long the car bounces and listen for the squeak. It could be a shock or strut, or in older vehicles a worn pad between leaf springs.
