2wd=2 piece drv shaft;4wd=1 piece? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67gmcstepside · 01-24-2010, 09:57 AM

Did v8 4x4's have the 2 piece drv shaft and 6 cyc have the 1? I see in the assembly manual KE109 and 209 = 2 piece and KA has a 1 piece.
Thanks

our 68 (LWB) I'm fairly certain came with a straight 6, but has a 2-piece DS.

AusTruck · 01-24-2010, 10:18 AM

My 69 SWB has a one piece driveshaft. It was originally a 6 cylinder turbo 350, is now a 350 crate motor (not any HP one though) with the turbo 350. Frame doesn't show any evidence of a carrier bearing having been there, so I'm surmising it had a one-piece driveshaft from the factory. Oh, its a 2wd also.

67gmcstepside · 01-24-2010, 11:51 AM

Maybe is as simple as LWB = 2 piece, SWB= 1 piece. Thanks for taking the time to respond. I hope to hear from a LWB 4x4 owner.

msgross · 01-24-2010, 11:54 AM

my SWB 4x4 has a 1 piece...

**too much stuff** · 01-24-2010, 11:56 AM

I "think" all 4x4 trucks had the one piece drive shaft. Long or short bed...

**Palf70Step** · 01-24-2010, 12:16 PM

It just depends. My 70 SWB Chevy & 69 SWB Chevy, both with 6s was one piece shaft, while Krue's SWB 70 V8GMC had 2 a piece. I would Imagine all 4wds are one piece. I have yet to figure the difference on SWB 2wd why some are 1 piece and some are 2 piece.

67gmcstepside · 01-24-2010, 12:16 PM

My issue is mine has the 2 piece and need to verify if its correct, LWB 4x4 2 piece. The assembly manual does show a pic of a 2 piece for the KE model.
Thanks.

67gmcstepside · 01-24-2010, 08:46 PM

Does anyone have a 67 LWB 4x4 with a single drive shaft?

ksbeatty · 01-24-2010, 08:51 PM

I have a 70 4x4 with a one piece.

67gmcstepside · 01-24-2010, 08:55 PM

Thanks, This is getting more confusing. 70 LWB 4x4 has the 1 piece. There must be a reason that some trucks got the 2 piece.

*vegaschevy* · 01-24-2010, 09:02 PM

There is also 2 different diameter shafts and 2 different styles of carrier bearings totaling four different possible carrier bearing set ups

msgross · 01-24-2010, 09:21 PM

could depend on tranny option as well since auto's are longer than manuals.

67gmcstepside · 01-24-2010, 09:37 PM

Thanks guys, Its tough when you have a frankenstien truck to start with. So far I have a 67 chevy cab with a GMC rad support and 4 headlights on a 67 3/4 gmc frame with 2 piece drv shafts running a 70 350/255 truck motor. 3 sp OTT with a T221 TC.
I apprecate the time helping me try to inderstand what I have.

71 super · 01-24-2010, 10:10 PM

My 72 swb is a one piece, brother's lwb 72 is a one piece as well, both are original units for the respective trucks

chevroletman223 · 01-24-2010, 11:45 PM

my 68 2wd with a th350 and 327 is a 2 piece and its origional

eric67m · 01-25-2010, 08:30 AM

1967, k10, 4x4, 327, sm465(4speed), np205(not stock), 2 piece drive line, wide mount carrier bearing on stock mounted crossmember.

mrein3 · 01-25-2010, 09:05 AM

FWIW, my 1971 long wheel base chassis, originally a 3-speed manual on the tree, NP205, had a 1-piece rear drive shaft. I bought a th350/NP205 out of a 1972 blazer and used my truck's original drive shafts. One rear and one front.

I've never dealt with a T221 transfer case. All long wheel base 4x4 I've dealt with had NP205s and a one piece rear drive shaft.

67gmcstepside · 01-25-2010, 09:26 AM

Thanks guys, I am assuming the 2 piece is original on my 67. I am starting to think 1/2 tons = 2 piece, 3/4 = 1 piece.
My rear only has 2 leafs not 4/5 so I am thinking its a 1/2 LWB hence the 2 piece drv shaft.
Thanks for the replys.

71meangreenc10 · 01-25-2010, 10:06 AM

I have never seen a 6 or 8 2wd that came with a factory one piece shaft. I have owned 8 of these trucks ( & burbs).....

Still looking for the 4wd that fits the needs.

71 super · 01-25-2010, 06:26 PM

As far a 2wd, my bb truck was two piece, changed to one piece, 68 2wd is 2 piece (both are automatics), had 69 swb with 6 was one piece (was 3 spd)
