Vibration solved!!!!!
Well I just got an IM back from Dan at Van Steel. It seems that the core trailing arms that I sent back to them had a spindle that was out by 12 thousandths. I've chased a vibration in that car for more years than I can remember. I checked driveshaft and halfshaft angles, I had the tires rebalanced many times, I even suspected that one of the wheels might be out of round. After installing the new suspension and putting new tires on, I took her out on the road and she ran smooth as silk. Don't discount your spindles as a cause for vibration because replacing mine made a world of difference. BTW the trailing arms from Van Steel were beautiful. :thumbs:

:cool: Would you have seen the out of round if you indicated the rotors? Was the flange bent or just out of round.
:lol:

I have a 69 that has a vibration between 50 - 60 mpg. Any ideas? It seems worse if I decelerate into that rang than if I accelerate into it. I'm thinking a U joint?

Re: Vibration solved!!!!! (jacobsed)
There are so many things that can cause a vibration it's hard to guess. First I would go with the easy things. Get the balance on the tires checked and make sure the wheels are true. Then disconnect the halfshafts and put a dial gauge on the spindle and rotor to see if they're true. If they are you may as well have the halfshaft u-joints replaced since you have them half off. What's left is the driveshaft and suspension. My car had a lot of shake until I replaced the front suspension this past winter with a VB&P monospring conversion. You don't have to do something that drastic but you should make sure all the bushings and tierods are good and the ball joints. As you can see it's a process of elimination and if your lucky you'll find it on the first or second try. If you're like most of us it ends up being the last thing you do. :lol:

Re: Vibration solved!!!!! (vettfixr)
Mine was due to loose bolts at the bell housing on the tranny. Probably not likely but check anyway. Vibration must have been flywheel rubbing. Started vibrating about 30 mph, got worse til about 45, then kind of smoothed out. :banghead: But it's gone now :hurray:
