vibration problem
I have a 84 chevy that I just installed a new 350 engine (replaced the 305), rebuilt tranny, and rebuilt driveshaft. When I get to about 45 MPG I feel a slight vibration that feels more drive train than tires. I had an expert drive it and he did not feel what I did. He inspected the drive shaft and found everything ok. My tires are new but I think I will take it back for re-balancing.
Anyone experianced something like this? Any suggestions? |

I had the same problem. Is it a long bed? If so it has a long driveshaft that at speed will flex and get out of balance. I had a 2 peice driveshaft made for mine. Thats the only thing that will fix that. I had 2.71 gears at the time so my vibration was at 55mph.

Just because their new tires doesn't mean they are perfect

Well, take everyones advice and check the Flywheel, Tires, and even pinion.
Mine vibrates a little because of the angle since I lowered it so severely. All these things come into play. Im not too sure how much damage it will do other than drive you nuts.

Check your front wheel bearings too, I was getting irritated with a bad vibe in my 85 Shortbed K10 and my front wheel bearing on the passenger side was loose, apparently I didn't install the lock ring right and it backed off.
