Rear end rattals when i go over a bump as if some thing is lose or broken

what sort of noise clunks&bangs could be anything from shock mounting bushes exhaust hanging mounts or suspsion bushes.it would be a good idear 2 have a mechanic put it up on a hoist 2 check it out

That is a sign that your rear shock absorbers a shot

First guess is bad shock absorbers. You may have a broken or disconnected 'track bar' that locates the rear axle laterally. Make sure that both spring assemblies are intact and nothing is loose. Check the control arms for damage and for loose or damaged bushings or bolts. Check the rear tire treads for abnormal wear indicating alignment problems.

Could be blown shocks, bad bushings, missing bump stops, damaged exhaust, broken exhaust hanger. The exhaust goes over the axle, if it's hanging low the axle could hit it over a large bump or when weight is in the rear. No telling until you crawl under it and take a good look at everything. How many miles are on it?

Please ensure that the tye rods are tight and that there is good wheel balancing and alignment.

Good luck and rate this.

universal joints clunk,is it in the rear end then maybe it is the rear end.you kinda need to be more specific if this information doesn't help

Sounds like a snapped or broken spring, you need to get them checked asap as could be dangerous.
As for antifreeze, are you sure you havent put screenwash in recently as this can smell very strongly of Alcohol.

I would check for a broken springs, very common. As for the missing, is there a check engine light on?

check shocks on back and sway bar for the engine wait until it dark and see if you have any sparks from wires and may need some new plugs i hope this will help you

has this car ever been over horrible bump or recently been in an accident? also another thing the rear end probably needs bearings replaced if t makes a bad squeeking noise when goin over bumps.
