Clunking noise when I hit bumps fuel low it stalls oil in anti-freeze

Get it to a reputable suspension shop to have it checked out,if it was said a part on the steering then you don't want to risk losing steering when the worn parts break.Speculating it could be tie rods,sway bar links,ball joints,bushings etc etc everything that moves when you hit the bumps.

Take the brakes apart & clean up all rust,check everything out
& lube things when putting back together
Have to do that at least once a year

Don't need machining every year or new pads, but have to knock
down the edge on the rotors & get rid of rust & lube (anti-seize on
everything but inside the caliper slide bolts, there you use the synthetic caliper lube

The clunk could be worn drive axle joints or drive shaft joints
or shocks
When your on the brakes or hit bumps your loading things differently & the clunk goes away

Could be time for a new van.
The oil light is warning the driver engine oil pressure has dropped below 10 psi, not necessarily that the engine is low on oil.
Common causes for low oil pressure is a faulty oil pump or screen, or worn engine parts.
The fact you are also adding coolant and you don't see any external leaks sounds like the engine is reaching the end of its life.

Sounds like a tie rod end

Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.

Front hub bearing. If you were the one who replaced the pads you should have turned the hub while the caliper was off and checked for roughness or wobble. Imagine the rotor wandering from side to side and rubbing the pads; thats what a worn hub will do.

have it put on a lift and the shocks and struts checked, they may be loose or defective.

Hi the most common fault on escort suspension is worn track control arm bushes followed by anti roll bar bushes i think you call them stabiliser bushes i would agree with your ford tech guy re the strut bushes let me know if it solves it

-it could be the sawy bar linkages
-but also check to see if the struts are leaking or that it looks damp
-but because you said it doesn't look like it bouncing when you hit a dip most likely it could be that the struts are dead
-check to see the cars ride hieght that would give you a clue

Hay I would check your sway bar in the front .The bal may have came out of the seat located under front wheel well. Also they could be just loose. Check by rocking your jeep side to side .
