Was driving along heard a noise like i ran over something, checked tires they were ok, had over two hundred miles before needed oil change but there was no oil in engine. put oil in still had the rattling noise took it out of all wheel drive put in in two wheel drive was ok put it back in all wheel drive the rattling noise was thereis it safe to drive for a coup[le of days til i get it fixed

What you ran over --no idea

What the noise is--no idea

What damage may have been done--can't
guess without the vehicle to check over,you
knew that

Did you not raise & support the vehicle & examine
things & check over the tires real good !

I would park it-- until I resolved the issue

lifter or weak oil pump

Maybe.
Be aware of any changes to steering control. Is it pulling to one side? I have an 01 z71 and my issue, which sounds "similar" to yours is a dry secondary steering shaft which,apparently is common among these trucks. Ask your Mech. to check for that possibility while you're there.

Wheel bearing???? If you dont know what it is, you cant fix it. get a shop to check it out.

hi if your talking about service then you need to find out when the timing belt was done last if it has not been done then its due.

other than that you need to check gearbox oil level
change oil and oil filter
change air filter
change spark plugs
change fuel filter
check tyres and tyre pressure
check lights working
check washer bottle fluid level and check its working
take it for a drive on a bumpy road and listen for any knocking noises if any are heard then bottom ball joint needs replacing.

i hope i have given you enough to be getting on with.

let me know how you get on or if you need further assistance ok

check the wheel bearing sounds like a problem there.

It is probably your lifters sticking. Check your engine oil level and if thats fine, then add some oil detergent/additive that says it will "reduce engine knock and free sticky lifters" run with that additive for a couple hundred miles or until the noise gets better. then replce your oil after that without using the additive

the 70 has a higher aspect ratio so it will ride smoother becasue it is taller between the wheel and the ground.

my car was stollen and used in a robbery and high speed chase.the strip was used to flatten the front tires and he still ran 1mile and a half on them flat.but my insurence payed to get it fixed after my 500.00 deduct.when i got it back i have damage to the front finder they didnt fix.and after i traveld 500 miles to come back home i have a bad noise in front when i had the oil changed i had him check it and he said something had gotten into the brake shoe pasanger side and chued it up now im afaried to drive it and dont have the money now to fix it is this maybe from all that went on with it he ran across a yard and colbert i was told that its hard to get stones in the brakes to do that kind of damege.should i go back to insurance co.i had asked them to make sure they checked out good now im in another state

If the engine overheated for any length of time, it may have some fried rubber hoses and worse, a blown head gasket. If the latter has occurred, in the next couple of hundred miles, oily deposits may show up in the coolant overflow bottle or an emulsion of coolant and oil on the dipstick. This will look like dirty hand creme if it happens. If the gasket fails badly enough, there may be leakage of oil or coolant on the block below the junction with the head. If the gasket fails between cylinders, the engine may seem really tired or misfire and eat fuel. 
Worst case; damaged piston rings, rod and crankshaft bearings along with damage to other seals and gaskets.
For right now, I would make sure the cooling system gets tight again, the oil is changed (it may have chunks of burned oil in it) and drive conservatively with ears open and NO MUSIC for a few days to listen for irregular engine noises that could be caused by the engine damage described.
