drive shaft noise - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

ok so while I was changing my breaks I noticed when I rolled the car back and forth their was a noise that sounded like something hitting the muffler so I crawled under the car and rolled it back and forth and it seems to be coming from where the drive shaft enters the diff it also does it when I'm taking off like something is loose.
Anyone had this issue before? or know what it might be? I don't wanna mess other stuff up.

Aluminum driveshaft is going to make some noises that sound pretty weird because there is no longer a dampener (hanger bearing/bushing) in the system... pretty much a solid line between the tranny & diff. If you also have solid or urethane bushings, rods, arms etc... you will notice it even more.

I have an AL driveshaft, It use to make noise,, could not for the life of me find out what it was. Found out later, the E-Brake cables were rubbing on the shaft, once the rubber wore off, the metal clinked against it and made noise, try feeling underneath the driveshaft see if anything is hitting it.

LMAO yea loose bolts is not a good thing

Every so often, it's good to get under there & make sure everything is tight... especially after adding new pieces as they sometimes require re-seating.

well I tightened the bolts but my car still makes a loud humming noise while im driving. It usually goes away at higher speeds it is extremely annoying . the car shifts fine and drives fine. I also noticed the diff was leaking a little around the plug could that be making the noise? or is my tranny about to go? could it be alignment issues? tires not balanced? wheel bearing?

Maybe your driveshaft needs to be balanced?

Hiighboost2 · 10-02-2013, 12:54 PM

If it is a driveshaft shop AL one, It is common for them to make noise.
