Car Forum / Honda Cars / April 2006rattling from under car
for the first 5 minutes or so after I start my 98 Civic, there is a vibrating noise coming from under the front of my car. In previous cars, the culprit has been the head shield which I have easily removed. The shield for this car is long gone so it can't be that. The noise seems to go away after about 5 minutes. Any ideas what it could be? My guess is that something with the exhaust system is loose.

Shake it when it's cold and see what's loose / touching what. 'Curly' > for the first 5 minutes or so after I start my 98 Civic, there is a > vibrating noise coming from under the front of my car.

Get an automotive stethoscope (sears) and probe around. Noises can be tricky to find as it travels.

You have approximately eight hundred heat-shields on your exhaust. If you get each entire part replaced at the dealer, they will come with new shields. Usually. There are a number of shields that are attached to parts that are excruciatingly expensive to replace (the cat, for instance). In those cases, you're best to either get them torn off, or spend the $50 or so for each shield to replace them. Sometimes a hose clamp can be tightened on to the shields to stop them rattling. If you get Midas or Speedy to do the work, you will get no new shields at all, and will be back the very next spring to get more welding done. In the end, it will cost you more than dealer replacements.
