Unhappy 350z U-joint issue?

Hello,

I have ran into a little problem with my Z. When I was driving on the freeway around 60-80 mph, I felt like my car was shaking and I have noticed something was shaking or vibrating loosely underneath the E-Brake. During a sharp turn onto the freeway I heard a very loud noise like something was breaking, though I was able to make it home. It only happens at high speed, however when I change from Parking to Reverse, I notice some clanking sound when the car moves, same with when I'm moving forward when I put it to drive (automatic). There was one time my car made a really loud noise when I reverse my car, like really loud. Though, at low speed (20-45 mph) I did not feel any movement or vibration.

I have looked up on the internet and suspect it to be a bad U-Joint, so I went and check my drive shaft. Though, everything felt firmly in place when I gave it a little tap.

If it is indeed a bad U-Joint, can show me where I can buy one? I have searched online and even call my local auto-part shops and I was unable to find one.

I love my car and thank you very much!

Unless the dust boot on one of your halfshafts is torn or damaged, a u-joint is unlikely to be the source of your problem. They are sold with the halfshafts (left and right) as a unit. I'd look closely at your rear hub/bearing units as a more likely cause of the vibration and noise, however.

Thank you so much for your help.

My brother decided to help me look at the driveshaft underneath the car. This is what we found, he applied some pressure to the driveshaft and helped it move when i put my gear in reverse, the noise and loud bang / clank was gone; We did that for a good a mount of time to make sure it was the driveshaft issue

With your invaluable help, I have decided to buy a good condition used drive shaft and I will have it installed next week. I love my car and only had it for 6 months.

Once again, thank you very much!!!

So we’re the u joints seized? Or was play found?.The most accurate way to check u joints is to remove the drive shaft from the vehicle and check them.My drive shaft had a bad u joint at the rear.It caused a vibration under certain conditions/decel etc.
While you’re under there verify the transmission mount is secured properly/bolts are tight.Hope you get things figured out ASAP.
Goodluck
