Driveshaft... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I shortened my frame from long to short...I have my long bed two piece driveshaft...Will I be able to reuse this or I am going to find another driveshaft? What are my options?

Thanks

it's 12 inches too long now... since you cut 12 inches out of the middle of the frame.
You can have it shortened, or locate a SWB shaft or shafts.

i would reuse trans yoke and weld yokes and have a one piece made if you can.

if going for a real low stance, 2 piece may be better. A 2 piece is truely a better set up, just takes quality parts to make it worth while.

Unfortunately I've got some experience in this area. As expressed above you can use your front and rear yokes and have a driveshaft custom made. It really isnt that expensive. I paid about $200 to have my driveshaft lengthened two inches. I know that sounds like a lot but really what I'm getting is a new shaft with my front and rear yokes welded to it and balanced.

I did what you did and I shortened my own drive shaft just took it out of the front that hooks up to the transmission. I split the weld to take out the yoke and shortened then re welded it is worth a shot. I thought it might vibrate at freeway speeds but nothing at all.

a 2 piece is better but when working with 40 year old parts, buying a new slip, stub, and carrier bearing when you could just get a 1 piece shaft made doesnt make alot of sense to me

after working in a driveshaft shop, i highly recommend not doing this yourself. while a diy job is great for getting your truck out of the field, you will be lucky to make a shaft that a pro can fix, most arrent that lucky, and end up spending more money than they were trying to save.
i have seen professional mechanics that couldnt properly install a ujoint if their life depended on it, much less try to weld in an end yoke straight enough to be useable.

I share your concern, it was supposed to be temporary so I could take it to the dmv to be inspectedt, but it worked so good I ended up just leaving it.
