Can you drive a car when the AC system is apart?

Have 1992 Ford Ranger 2wd automatic 4.0L V6

I haven't had AC for last 10 years i don't know if the owner be4 me had any AC for the truck.
Anyway there a bad leak. I know there no pressure in the lines. I like know can I take my AC system apart and still be able drive the truck around?

Not really looking to fix it, don't think it can be fixed. More of just wanting know what the problem was all these years.

Side question… Last time I tired put refrigerant in the hose came lose and bunch of white chunky stuff came flying out of the place I put the refrigerant. Isn't this stuff a gas?

Why are Lamborghini cars so heavy?

I just found out that the curb weight of a Lamborghini Mucelargio is 3,600 pounds. That's 500 pounds heavier than a Ford Ranger pick-up truck (3100 pounds). That's crazy. I thought that super exotic sports cars were supposed to be extremely light. Why so heavy?

Rattle noise from front end when driving through bumps?

My 97' ford ranger truck has this noise while going through bumps and even small cracks on the road. The noise is a rattle noise and comes from the driver's side front end. The noise could be best described as a metal tool box with a wrench inside that shake around while driving over bumps. Just imagine a metal tool box with one loose tool inside hitting the metal box. It is not a loud sound but still able to hear it clearly and is quite annoying. My guess is some suspension component?

Ford ranger, 10 rear drum to disk conversion?

How much work would it be too convert my rear drums to disks? I have a 99 ranger v6 4l. My drums are the 10". My where base is the bug one I'm pretty sure like 144" or 141". Where would I buy them? If I buy a kit do I have to always use the kit brand disks?

Noise coming from engine on ford ranger?

I own a 97' ford ranger v4. I noticed this afternoon that there's an unusual noise coming from the engine area or under the hood noise. The noise could be best described as rock shaking inside a metal container or as a bicycle's busted wheel bearings and you can hear the bearing grinding while the wheel spins. The noise is constant and appears during idle. The noise goes away as soon as I press the accelerator even by pressing a bit, but comes back right after I release the accelerator. Is it the chain thing inside the engine, that's my only guess.
