strange noises

my question is that after i drive at highway speeds for any extended length of time when i exit the highway and i stop for the next few miles of regular surface street driving i will hear a clanking sound coming from under the jeep. ive checked all the bolts and the exhaust system to see if that was it but no luck any ideas on what to check next

Re: strange noises

Hey try to check your catalytic converter shields...after running at the speed limit...hehe... there is alot of heat built up in there and without us knowing your motor could be running alittle rough. Thos shields are only 'tack' welded on there...and with alittle heat and cooling rust settles in. The shields are very important! so please do not remove them if you still plan to offroad at all...i have seen many fires by people parking there vehicles on the high grass. The best thing to do if this is it, is to use a couple of hose clamps to go around the cat and the covers to secure them...and no dont replace the cat if it is the shieds...Ive seen a couple and heard a couple stories of mechanics trying to sell unknowing people catalytic converters because of the shields loose...and check the steel line that runs to the cat also...follow it all the way...and wait a while, its very hot. Check your shocks to see if there lose, brake lines, fuel lines and try to check your clutch setup too...
