Factory Aluminum Driveshaft?

[Boost Addict]

Damn forum typing.on the phone

The one with the dampener is for sure a stock front joint. Can see the plastic protruding out.

Tje dampener os for balancing unfortunately when the rubber wears it creates vibrations in itself. To tell if they are stock when you do u joints see if they are injection molded in, never geat them to melt the plastic inside though never ever.

Huh?

Why would you not want to melt the injected plastic? It's the only way to replace the u joint...

Is it possible to throw a pinion yoke out of balance? The vibration i experienced when the cap first broke was BAD.

weld yoke can absorb shock, not outward pressure, melting the plastic usually makes them explode which can damange the yoke, pressing u joints out can spread the ears as well. best way to do them is hammer them out, the injection molding isnt that hard to break.

like i said on the phone if that dampener is attached with rubber between that could be causing a slight vibration if its whipping. aluminum doesnt tend to pull alot after welding and most GM shafts are pretty dead on theres a few ive seen that were crap but at the 3-3.5" dimaeter tube mark there isnt much pulling. replacing that front joint might not be a bad idea, but may not be the issue either.

if its not seated right, offset or damaged in some way it could cause runout in your driveshaft which could result in a vibration. i wouldnt think the pinion would start coming loose randomly either.

I've done it all ways with these aluminum shafts. No heat and 20 ton press will result in a bent ear, and the press will do one hell of a jump when it lets go. High impact on a joint will result in marring and a bent ear, doesn't always let go.

What's so bad about slowly heating the plastic until it expands and then popping the u-joint out? I've done dozens this way. Rosebud tip and some pressure results in no deformation of the ears, takes me 10 minutes to put new joints on both ends

[TylerT/AZ28]

its when the plastic actually pops out is when it damages it. shock is actually best it could bend an ear yes but usually if its already broken, and if you hit it hard enough and dont play with it you wont have any issues at all. a drift and a good solid hammer is how i did them at work all day long.

Have you checked the trans tail shaft bushing for excessive wear?

[TylerT/AZ28]

looking at the slip yoke it doesnt seem to have any wear there but its not all that great of a pic either.

Maybe it will be obvious when i get under the car, but im not quite picturing what you mean by that. Where is that bushing? Am i just checking for slop in the output shaft?

The bushing supports the outer dia of the slip yoke.

[TylerT/AZ28]

if the bushing was wearing adn whipping itd show on the slipyoke, if i recall properly the bushings insde there a bit, or maybe thats the bearing both i think require a special tool to remove.

There is a bronze bushing inside the tail shaft housing (that the slip yoke rides in) that wears out and cause alot of people grief. You can check the condition of the bushing by how much play the slip yoke has up/down, side to side. You can either replace the whole tail shaft housing or you can just buy the bushing from Tick if you find yours is worn.

Is the bushing component #99 in this exploded view?

If this piece is bad would you be able to notice slop in the driveshaft with it still installed in the car (moving it by hand)? Mine is 100% solid, it doesnt budge even if i quickly switch from military pressing it, to hanging my full weight on it.

Starting to wonder if its a wheel thats out of balance.

Think it's 85
