Hey all,
My 78 TA needs new springs. Is Detroit Eaton the best bet? Looking for stock height and ride. Do these repro springs last?? My car has the original springs.
I might change the harmonic balancer. Does anyone have a resonable source?

Most springs that the resto houses carry are the same if not better than original equipment and usually a little cheaper. They are usually made from the original blueprints and specs. Don't waste the big money on NOS or something like that.

Most resto house carry a replacement type harmonic balancer. My buddy that works at a dealership in parts said that GM is getting ready to move the 70-79 or so Pontiac Harmonic balancer inventory to another source. I guess like Parts Direct or something, so expect the price to increase if you can find a GM piece. If thats what you're looking for. Is your balancer bad?

Yes,  At first  i thought it was a bent/warped  crankshaft pulley. Bought another one from F body warehouse.  Had reliable shop  check it and its the balancer that is causing the pulley to wobble.
I didnt know GM still  had em? Ames sells a repro.
The shop recommended Moog springs .
My car has almost an original front end so its time to rebuild it.
Worn out control arm bushings were causing the front end to knock when hitting the brakes . Thats what started the ball rolling.

That's usually how it starts. A simple repair turns into a major overhaul/restoration. I think we're all guilty of that.  :lol:

I bought my OEM hamonic balancer from Autozone, $102.
Thats one part you can get cheap on or it may cost you in the long run.  
I have heard of a bad hb shear off the end of a crank and cause the engine to throw a rod. :shock:

***RAISING HAND***

It happened to me.  My harmonic balancer hub cracked and the pieces fell down in the engine, jamming into the timing chain.  It looked like a GRENADE went off in the bottom end of the engine.  Four of the five main bearing webs were broken completely out of the block, two rods exited via the oil pan, and the crank broke into three pieces.  When I pulled it, the engine sounded like a baby's rattle.

It is NOT a good thing... :shock:  :?  :(

OUCH! :shock:
Well there you go as testified by Rick.  Be sure and replace it with an OEM hb and not the cheap one.

Going check to see if a GM hb is available.
A front end rebuild is the only way  to get the car to corner the way it should. The worn bushings really affect  the way the car takes  turns.
Does anyone have a guess what a front end rebuild should cost with springs?????????
