My 1998 Jeep Grand Cherokee is running very loud, especially when I accelerate. It sounds like its coming from underneath in the exhaust system which was replaced a year ago. Could carbon build-up in engine contribute to this problem?
I change the oil regularly with pure synthetic. Please help me.

Re: 1998 Jeep Grand Cherokee running very loud.
Does it have the 4.0L motor ? if so open the hood stand off to the side where the exhaust bots to the head and have some one rev it up quick if its coming fron under the hood by the engine the exhaust manifol is cracked. The 4.0L jeeps have had lots of problems with this.

It would be hard to guess at you electrical problems but get your brakes checked.It sounds like your pads have worn down to metal on metal.Very dangerous and can get expensive to fix the longer you leave it.A visual inspection can tell within minutes if this is the problem.If this isn't the problem the 2nd most common thing is a loose brake caliper or caliper mount.A friend with some mechanical knowledge will be able to check the brake pad thickness very easily and quickly with just a torch.Hope this helps
You do have a filter and it's mounted right on top of the pump on outside of tank...it is also the pressure regulator. You really should put a pressure gauge on the fuel system and check it out though. you may find there is a problem elsewhere. Good and proper testing is the only way to get answers about problems especially now that systems are all electronically controlled.
