Weird Vibration by Diff

[loveTOspeed]

I have a weird vibration by my Diff, I kind of think it's near the front though. Anyway, it only does it around 3500rpm no matter what speed. My drive shaft is good and same with the trailing arms and all that. When I go idle speed (like at a stop light) I get a tinging sound 1 ting for 1 turn of the drive shaft. I don't really know what's going on and it's not constant, only when everything is warmed up. Can someone help me out?

A thorough visual inspection may be helpfull in narrowing down the problem, and it may be that you have more than one.

The rolling, once per driveshaft rev "ting" sound may be a U-joint on the center driveshaft. Many times, there will be a ring of rust around the bad cup/spider. It could also be a c.v clamp that's come astray.

tease: or one of your buddies with the zip-tie around the driveshaft trick...not that I would know anything about that, or anything )

Does the engine vibrate at ~3500rpm with the car sitting still?

That rpm range may indicate a broken balance shaft belt.

This should be addressed promptly, as the broken balance shaft belt can get sucked into the primary belt, causing it to jump time.

Not at idle, I got my car up on a lift and I noticed that the joint was new but the carrier bearing was pretty much shot, I ordered a new one a couple days ago so I'm hoping it'll get here before I drive to colorado. Thanks for your help though, I'm glad someone's willing to help out the new guy
