Saving Granddad's Falcon

[dhbfaster]

Hello guys!
I finally got out for a nice drive, 34 miles or so and rolled over the 500 mile mark on the engine.

Now I can finally stop using the break-in oil and change to 10w30. YaY! Plan to take care of that tomorrow.
On the drive though, it really seems like the driveline (pretty sure it?s the rear end) is both loosening up a bit (quite sloppy) and getting noisier. I was starting to get concerned.
Those of you who followed my thread ?back when? will recall that I rebuilt the rear axle myself (I felt way over my head on that...) with all new bearings, but kept the original ring and pinion that did have some pitting. So...looking for your thoughts...
1) Sloppiness...did I not shim the pinion tight enough?
2) The noise...is like a hum, seems to be getting a little louder than it was before, especially when I get up to 55mph or so. Would that be from the pitting that was there?

Thoughts?

It's tough Don to make an assessment on a rear-end noise in most cases without actually pulling the cover and just seeing how it's setup. The pitting I see hear wouldn't make much of an audible, but having the pinion engaging poorly, or in the wrong spot, could contribute a lot. The bearings all being new should nullify them, so I'm thinking it's probably sloppy or misaligned somewhat.

NIce!
Read your posts about saving the falcon a while ago. Nice to see you've got it running.
I've got a pertronix with a flame thrower coil as well.
I've got a pertronix 1 in the car.
I also had some troubles with idle and hesitations even though I had a pony carb that was supposed to eliminate the stumbles.
I tuned the car with a vacuum gauge, timing light (after I swapped my slipped old balancer for a new one!!!)and the screws on the carb.

Basically you ere aiming for as high a vacuum you can get and then try to dial in the idel as close to the factory setting with the idle speed screws.

It turned out my timing was way too retarded.

Good luck with the rear. I'd wish I could help you on that one, but My only experience with rebuilding my spare diff resulted in me having to swap in my original diff due to a broken refurbished diff (extensive oil leak past the input flange caused it tu run dry without me realising how severe it was).
