Squeaking upon deceleration '08 Sentra

[jlevey]

When decelerating and just coasting my Sentra squeaks. Not squeals but squeaks, it sounds like mice or something. I don't think its anything to do with the brakes because it happens even when not braking. It doesn't happen at higher speeds. I was wondering if anybody else has this problem or what they think it could be, because I'd really like to fix this problem without spending hundreds of dollars just trying to diagnose it.

Any idea what part of the car its coming from? Drivers front/rear, passenger front/rear? Engine bay? Is it RPM dependent?

uhhh all I know is that if I grab the muffler and shake it will squeak, and push it back and forth from the front it will squeak. my dad seems to think its the motor mounts squeaking but I'm not sure of that

I also think the noise is coming from the front

I doubt its the motor mounts. It takes a lot to shake those. Its probably an exhaust hanger or bushing somewhere. Is it still under warranty?

[jlevey]

It isn't under warranty anymore yea my dad also said it was probably bushings, so we tried using pb blaster on the ones we could see, it worked somewhat, but after about a week or so it was squeaking again. He told me I should probably just get over the squeaking but I hate it! lol

You're really going to have to jack the car up and put it on jack stands. You'll have to crawl under there while someone pushes on the exhaust like you were talking about. Pinpoint the squeak, and handle accordingly. PB blaster is a poor lubricant to kill squeaks. Try using white lithium grease, vaseline, or other general grease lubricant.

I will try that, thank you for the tip
