very bad problem
 

ok i was driving home from my buddys house and on the way home my truck started making this clucking noise, then it started shaking really then when i tried to stop the brakes didnt work either!
i really dont know whats wrong with it at all. I looked under there and i didnt see anything at all.

does anybody know what what it could be??

a number of things.. well maybe not a ton of things but help narrow the search area down...
where did the "clunking" and shaking come from?

well it feels like the front pass. tire area

is anything loose?
thats where i would start

not that i can really tell from looking at it

i would take your wheel off and see if your brake caliper came loose. it's happened to me and a few other people as well.

would that make it shake like i didnt have lug nut on tight

well start grabbing stuff and wiggling it, jack it up and start shaking stuff.. you'll probably have to wait until tomorrow but thats all i've got for now.. idk about the brakes though maybe the caliper bolts or caliper bracket bolts...

probably

yeah ill try that, i really hope it is that haha

Set the truck on jack stands and start shaking the wheels. If you have a friend that could help you, have him/her turn the wheels (not from the cab while its on jack stands!) while you are looking at the passenger side. Check everything! Not just the wheel!

As Matt said, it could be a number of things.

found out what it was, my wheel bearing went out

does anyone know how hard it is to change to bearings out

i found this for a 1994 ford ranger 2wd i hope this is close enough to what you need

you first take the tire off. then you take caliper off and then the dust cover, then take the codder pin out. Unscrew the bolt and pull off rotor be carefull the front bearings are not held in by a seal so they will fall out when you take the rotor off. To take the rear seal off and get the bearing out go from the front side take something like the end of a wood hammer, stick it through the center and put on the back of the bearing. take another hammer and pound the bearing until the seal breaks loose. Take the bearing out clean all the grease out with an alchol based cleaner then take your new bearings be sure to pack them well and grease up the inside of the rotor and stick the rear bearing in tampered end down and use a block of wood and pound the new seal in and make sure it is level all the way around with the metal. then stick the front bearing in tampered end down and then put your washer on top of bearing. grease the spindle up good and put the rotor back on the spindle and make sure you break the bearing in by spinnig the rotor and tighen and loosen and tighen and loosen the nut about 4 time to break the bearings in. Make sure you put new cobber pin in and put dust cap on and caliper then put wheel back on and you are all set to go.
