Driveline Vibration

Just prefer to move them out a bit. Still maintaining the stock look.

Yah, cant wait to change out that tranny! It's all i think about now.

I've had 15x7 steelies that your style hubcap would fit.  Came from an older full sized Caprice.  They looked better than the 15x6 that you have now

Gotcah, makes sense.  Like I said I'm a dork. 

Seems like you should be able to find another TH350 pretty easily and for short money or just get the one you have fixed.  I had a freind that had one checked over a few years ago and it didn't cost him a ton.  Then again if yours is really bad then parts might start to add up...

What is the exhaust spring kit - is that for at the factory manifolds?

Yes, where it connects at the manifold. I'll get that done at some point.

Yah, 15x6, love the thin tires.

Well, make one change at a time, and report back as you go.  Do the cheapest/easiest fixes first.  I'm looking forward to hearing your results.

Thanks skinny, best reply i had in a while. Good advice.

If you look back to some earlier posts, I stated that often the vibe is hard to detect, like after the vehicle warms up and I stop then start again, although I never could get a pattern out of it. Anyway, now its pretty steady, often it no longer pulsates, it's just continuous. But it's always there now...which really gets my goat! Like you want to take a sledge hammer to something and let out some steam.

We're starting to break ground! The monster has been isolated and revealed itself. Stay tuned...
Oh, and thanks to VZ...again.

Ps. I know i already mentioned the tranny, but today i took the drive shaft in to re-size, and ran it w/o the shaft, as Vile mentioned he did also, smooth as butter in park. In neutral and drive....there it was!!

1. Smooth in park=not engine or TC
2. No dshaft=not driveline or rear end(obviously).
3. Hmmm, whats left? Bingo!

So this confirms its the trans? not the flex plate or torque converter?

[philo_beddoe]

Without a doubt, 100%!

Not sure, but perhaps its the front shaft .

Just dropped truck off at VZ's place. Man what a blessing to live near him. I mean, where else would I go, some hack mechanic who will overcharge me? I know, there are some good shops out there, but not many have extensive knowledge on the classics. Anyway, it looks like the tranny is getting swapped out. I have a strange feeling the front shaft has play in it. How could it be the internals?? We'll see. She's in the best of hands. I just hope Vile doesn't text me telling me he found some new unforeseen problem that I have to make a decision on. That always means $$$$. Then again, Christmas is near....Lol.

When my TH350 popped this June, I rebuilt it with all new bushings and some heavier duty parts.  Made no difference to the vibration at all, but it's still mostly all the original rotating hard parts.  I was quite sad.  Trans is a ton better, though....

[philo_beddoe]

That would drive me nuts, still feeling the vibration after all that. For me, if i cant see, feel or hear it, then life is good. Thus rust, vibrations and rattles really get my goat.
