How many cans of freon does a 01 ford expedition takes

134a refrigerant not freon

revise el systema de el pression de freon, necesita freon, el systema de enfrente usa menos pression de el de atras.

add R134a freon and use a fill hose with a gage and keep in safe range. Keep can upright to fill system as a gas. Inverting will send a flood of liquid freon in - not good.
Can you hear the a/c clutch engage and disengage a few times/minute?

This may be due to freon charge level. May want to have freon recharged.

on the low ressure line, there will be a nozzle that you connect the freon kit to. The kit will not fit on high pressure line.

FIND THE ALUMINUM ACCUMULATOR AND YOU FOLLOW THE LINES YOU WILL FIND IT

These vehicles need a special mechine to recharge the AC. You cant use the old freon cans to charge it up.

I just did this on my f150 supercrew, which looks identical to my 2000 expedition. follow the freon lines, usually next to the battery, to the firewall. tucked against the firewall is the condensor and just above it is the low pressure access port. I topped off my freon using a kit with a pressure gauge. the before pressor was 40, and after the freon addition was 50. Made ALL the difference between a slightly cool AC and FREEZING COLD AC. Total cost with tax for the kit was just under $30. The kit inclued an 18 oz refill container (17 oz freon + 1 oz synthetic lubricant in the can) and reusable hose/pressure guage.

i suspect it's the bushings for the front stabilizer bar. Need silicone grease or replacing.This assumes 4x2, not 4x4. #3 is the bushing.
Could also be upper arm with ball joint. These are lubed for life, not greaseable. But you could spray WD40 to see if it stops temporarily. see # 1 in 2nd illustration.
