I was riding in my dad's jeep yesterday. 95 cherokee sport. I noticed that there was a constant drumming noise in the passengers area behind the glove compartment. What mite be causing this?

 

If it is like a rubbing or grinding it's the wheel bearing.

 

I know for a fact it is not the wheel bearing. On my jeep 98 cherokee classic i need a new drivers side front wheel bearing.

 

Possibly the blower motor going bad and making noise.

 

can you tell me what that does.

 

What it does when it's going bad, or just what it's function is?

 

what the function is

 

The blower motor is basically a cage type fan that forces air through the heater core for your heat in the winter, and circulates the air for the AC in the summer.



With age they will wear out and can rattle.

Before I mentioned the blower motor, I should have asked a few questions.

Do it makes the noise:
constantly while driving or parked?
only while driving?
with the heat and AC off or only when in use?
Is it a low rattle, a thumping, a knock?
Does it sound like metal against metal?

Sorry for so mant questions, but it may help narrow down the cause.

 

its while running and parked, its low rattleing like drumming, its not metal against metal. it does this when ac and heat are on and off.

 

check the emergency brake hook thing (not sure what you wanna call it) the thing that holds the e-brake cable off of your muffler it might have come unhooked and be rattling on your muffler. or for that matter check the entire exhaust system could have a loose hanger

 

Its not the exhaust system at all i know that its some where in the passenger front

 

Does it keep a steady rhythm or does it change depending on what the vehicle is doing, normal driving, under acceleration, during braking, while cornoering.
