Propeller shaft / Drive shaft

Is that the same thing on a 94 AWD Astro?

Thanks.

Prop shaft goes to the front. Just like on an airplane!

And the drive shaft?

The mecanic said prop shaft.
I have to replace it, but can't find it online. only drive shaft which looks the same.

My question is:
Is drive shaft and propeller shaft the same thing?
Or two different shafts?

Sorry if that was'nt clear.

Well, my best guess is that, since an astrovan actually does not have a propeller, he is talking about a driveshaft and using terminology that is uncommon to most of us.

However, if you van has one or more Propellers mounted on it, a propeller shaft may be what he is referring too.

Would it be cool to swap a Pratt & Whitney PT6A-67B or Rolls Royce 250C28 engine into your astro instead of the more common SBC swap? lol

the prop / propeller shaft comes off the front of the transfer case and goes to the front differential. The drive shaft comes out of the back of the transfer case goes to the rear differential on an AWD van

Let's end the confusion. "Propeller shaft" and "drive shaft" are interchangeable terms. A propeller shaft is referred to as such because it propels the vehicle. AWD Astros have a front and rear driveshaft, and that is how they should be referred to on AWD models to avoid confusion.

Not quite that easy. It could be the shaft that propels the front tire, right or left. Heck, I'd just call the guy up and ask. Jim

I'm still a bit confused.

Its 80 cm (31.5 inches) long

Hey who woulda thunk that a picture could clear this mess up.
That's a draft snake that you would use to keep the draft out. It goes under your front door, NOT.

Olalof, That is in fact your front drive shaft. Jim

Ola, That looks very expensive. Is there a way to rebuild the one you have? Jim

I looked into that (but in sweden everything related to american cars is expensive) and it would cost equivalent of around $600

RockAuto.com has it for $186.79 + $53.90 for a total of $240.69.... I can't believe how that went up in price. i swore i bought one from here 2 years ago for half that price, but i have been wrong before.

Ola, That is the correct part. Maybe someone will have a suggestion as to how you could do it cheaper though. Jim

there are different names due to many different things. where people were taught, who taught them, and components involved. your particular shaft has two different joint combinations on it. on the left you will see two u-joints in a h-yoke. this is a double cardigan joint. it has been mislabeled for years among almost all different types of mechanics from 8th grade auto to ase pros as a cv joint. this was never a problem untill an actual cv joint appeared on a drive line as shown on your right. they are great for eliminating very small vibrations in a drive line that are not exactly balanced. unfortunately in comparison to a u-joint there are 6 times more moving parts so they cost more and also are weaker than standard u-joints. some feel that with different terms such as propeller shaft since in fact the drive shaft in the front of the van is a hybrid with multiple joint types they will sound more educated and also with that demand a higher premium for parts and labor on such a part.
a few other things that have different terms

the center differential on an axle is common to be called the pumpkin by older mechanics.
a windshield is known as a wind screen in other parts of the world and on motorcycles.

at that i can make up names for things too. like i could call an air filter an element elimination module. its still the same thing on the car.
Don't explain it poorly 5 times. Take the 15 seconds to go out and take a picture of it!!
Please do not confuse idle conversation with technical advise

Thanks a lot for all the help!
Would'nt know what do to without this site.
:ty:


Will order the part from rockauto.com
The total is $337 (2400 SEK) with shipping.
The price in sweden was $770 (5500 SEK) so it's a pretty sweet deal.
