Was out in dad's whip picking up water from a spring 10 miles away. On the return 2 lane split 55 posted limit car pulled out of a business establishment right in front of me. It was either smash them at 60 or leave the roadway. Miracle I didn't go head on with oncoming vehicles. Car took it well under emergency handling situation.

[JacintasHot]

Made it out okay had to get checked in ER after getting the vehicle out and home.
Reason I'm posting is this:
Post off road testing while driving revealed a "harmonic resonance" in the clutch pedal and shifter while at constant speeds higher rpm in lower gears most notably 2 and 3. Now I'm a little pissed as my dad and I built this car 14 years ago with him currently being 80 he can't "get after it" like he used to. I don't think the car did it prior to the incident. Any ideas where I should start looking? It's not in the tires as it won't do it with the clutch depressed.
THANKS,
Chuck

See if a friend can get in back seat and have him move around even if he has to take a ride in the trunk. Hopefully he can pinpoint the side or if center to determine if you bent an axle or wheel or maybe the drive shaft. Also look closely at your driveshaft to see if it knocked off any of the balancing weights including balancing weights off your wheels. usually there’s a fingerprint where there used to be welded on. if it’s missing I would weld a washer to the driveshaft in that spot and see if it starts to help if it does add more washers till it’s gone then take the driveshaft out and have somebody correct it properly. You mentioned that you had all the wheels checked too. Does that mean the wheels were off the car and brought to a tire shop for balancing? Also running it up on a Lift will sometimes help find vibrations or create a sounds and noises that are normally OK but during unrestricted torque loads you will get weird sounds that are normal that wouldn’t happen with the wheels on the ground as you drive normally. Hope it helps. I’m always trying to find vibration issues at work.

A scary moment. I'd check underneath the car to see if anything got bent or damaged, maybe the driveshaft took a hit.

[pggto]

Bent driveshaft?

[jrunner]

Glad your ok and your car too hope your able to fix it soon so you and pops can go cruising.

[sdbob]

Yes, glad you are ok. Car looks beautiful from picture. Sorry for the accident. Myself I pray everytime I go out,people txtg, not paying attention. Then old people like me, gulp, having a senior moment. I found my bent axle by going g up long hill by my home,removing driveshaft and coasting down hill. Probably other ways but I thought suspension would be loaded.

Maybe some vegetation (looks like corn) under the car in the clutch and shifter mechanisms, or damage to same?? Or damage/debris to the exhaust system or driveshaft?

When I was 16-17 I had a similar episode. I was on a two lane road, it was raining. Speed limit was 45, I was going about 50. A woman entering the road from my left waited until I was right up on her and then pulled out in front of me. I got on the brakes, trying not to lock up. I started to fishtail to my left, into oncoming traffic. I corrected and got back in my lane but then ended up having to go off the road to the right into someones front yard. My car stopped about a foot from a very large tree.

Has anybody confirmed if the vegetation was, in fact, corn?

I'm thinking white corn. I don't know why...

Based on the photo I'd have to say yes.

Definitely not beans, or cotton, or even soft/hard wheat.

Glad you’re OK and that beautiful car didn’t encounter a worse fate. Love those 66 wheel discs. Hopefully you can get the vibration sorted soon.

[JacintasHot]

Guys thanks for the concerns.
I went all over this thing yesterday.
Not even a scratch on those wheel discs let alone under the car.
The vibration only occurs with the clutch out.
Wierd.
THANKS,
Chuck

I had a bent rear axle housing. Ck it.

[OCMDGTO]

Yikes! Glad that beautiful car wasn't smashed

[mzbk2l]

Bent rear control arm or torn bushing, or broken trans mount or bent crossmember? Something that could change the pinion angle or working angles of the u-joints?

Exhaust pushed around to where it can rub on something it didn't touch before?

[jhein]

From this picture, it seems like the car would have been riding "high" as you went off the road. When you reached the bottom of the swail, and hit that rise just before the corn, you would likely have bottomed out and all the important stuff under the car would have hit the ground with significant force. It also appears from the tire marks that you were going at least slightly sideways, not straight. Something is buggered up under there.

Does it vibrate with the clutch out in Neutral? Or only in gear?

If only when it's in gear with the clutch out it's sure to be something from the driveshaft back. Could have shifted or damaged a universal that only presents when under a torque load.

I don't know what it does in neutral but as soon as the pedal is pressed in it stops with the shifter in gear. I'll be looking from the driveshaft back I think.

A trip to a good alignment person might help...
