Vibration over 60mph

HAve a 67 camaro. When I get over 60 my car has a vibration, the drivers side door and the seat will even rattle. It is rythmic though. In other words it's not a constant rattle it goes in and out. Could this be something with my driveshaft?

Could be worn U joints, go underneath your car and turn the drive shaft by hand and check it there is any play in the U joints.

Vibration when going over 60mph

Have a 68 camaro. When I get over about 60 I get a vibration, my passenger seat and door actually start to rattle. It is a rythmic vibration though, it goes in and out,it's not constant. Could this have something to do with my driveshaft? Ideas?

Re: VIbration over 60mph

Can you drive through the vibration.. Or does it start at 60 and continue to vibrate no matter how fast you go?? Do you feel the vibration in the wheel or do you feel it through your butt?? when it starts vibrating and you shift into neutral does it get better or stay the same?? Does the car pull does it track straight??

More info the better..

Me too. Bring it to a driveshaft shop and they can actually spin it and tell you if it is bent or out of balance.

Re: VIbration over 60mph

sems like i would also check driveshaft u joints first-but need to take driveshaft out and swivel u joints, when dry and wore -you will hard spot when trying to swivel them--also check play at yoke where driveshaft goes in trans, trans tail housing bushing bad or galded -a bad ground to frame can cause this

Re: VIbration over 60mph

I had the same issue in my '67, turned out to be the front wheel bearings. I took it to a place near my home and at first they thought the spindles could be bad but it just ended up being the bearings. I also later replaced the U-joints but that was because the car would mke a strange sqeak or whine at slow speeds. Hope this helps

Re: Vibration over 60mph

Okay, I'm taking it to a driveshaft shop this morning. Doesn't appear it will cost that much, regardless if it's driveshaft balance, u hints, etc. Thanks for the info guys.

Re: Vibration over 60mph

I just went through this vibration thing with my daily driver Cherokee. It has done it for quite a while but wasn't real noticeable since it rides like a truck to begin with. Turns out that I have an out of round tire. They are warrantied so it will go back to the tire shop when i get a chance.

Re: Vibration over 60mph

I know this thread is a few months old but I'm hoping maybe some of you guys can help me with the exact same issue on my '69 Camaro 350...

I get a "rythmic" vibration above around 65mph. The vibration goes in and out rythmically just like tbd67 mentioned. Had the driveshaft balanced and u-joints replaced yesterday thinking that was the problem. That certainly helped with the overall ride, but I still get the rythmic vibration. Any ideas? tbd67, did balancing the driveshaft fix the vibration on your 67?

To answer Speedjester's questions... The vibration seems to smooth out around 88-90mph... Now that the driveshaft is balanced, the vibration seems to be mostly in the steering wheel... When I let off the gas at speed, I'll still get the vibration... and yes, the car tracks straight.

Any help would be much appreciated, guys! Thanks!

Re: Vibration over 60mph

Ha! Had the wheels balanced and the alignment done. Those were the first things I tried... I should have mentioned that. Any other ideas?
