Driveshaft / U-Joint Tech 1967 Coronet 500: SUMMARY

[ws27]

Isn't that a total of 80 out? Don't laugh, but maybe you can straighten it out if you can find the high point.

So they didn't check your old shaft or make you a new one?

That is allot of runout, my car is here this morning so I checked it and its at .015 total.

Just to double check is your rear yoke nice and tight for the u-joint fit?

Yes that is 0.080" runout, which is alot. I am an industrial vibration analyst, so I deal with vibration problems everyday, and dynamically balance alot of equipment. For example majority of electric motors have a spec of 0.003" runout max depending on size and rpm. With that runout I suspect your driveshaft is out of balance because of it. I would just get the old drive shaft rebalanced and a better shop that knows how to treat their clients.

No they did not check my drive shaft. I had called to make a appointment and they said we don't make appointments. Just come on in!
So I did. As with the counter banter I got. I took my shaft and left! My face as red as a tomato!
I put the shaft back in the car to move it while the epoxy guys did my floor.

So now I have data that supports a new driveshaft. Ill do the mail order via the Internet

Yeah he sounds like a jerk I would walk also.

On a possitve note how did floor come out?

Opps double post.

Floor looks awesome and my 67 in there makes it nicer!
Things are adding up now. New Trans mount. Car shook so hard! I put the old mount back in. Replaced the tail shaft bushing. That made a improvement yet did not go away.
My plan: new driveshaft and yokes.
Reinstall Trans mount. Recheck angles. Drive! And hope its gone!
