One piece drive shaft

Is is common for an '87 GMC Suburban to have a one-piece driveshaft? :crazy: It's equipped with a TBI 350 with 700r4 trans. 2 wheel drive, 1/2 ton.
I have a 90 and had an 85, and they both were/are equipped with a 2 piece DS, both 350s with the 700r4, 2 wheel drive, 1/2 tons.

Re: One piece drive shaft

Is it 2wd or 4x4? Both my 4x4 Burbs have a one piece drive shaft and the two 2wd Burbs I've had came with a 2 piece drive shaft.

Maybe GM was running short of 2pc shafts in '87. My '91 2500 is a 2pc.

I wonder what the critical RPM is on a one-piece shaft as long as the one in a Sub.

Re: One piece drive shaft

Both of my 2wd (82 and 84) burbs were 3/4 ton. Maybe that might be a factor.

Re: One piece drive shaft

A suburban has the same wheel base as a long box pickup (137.5 in), so it shouldn't be all that uncommon to see a one piece drive shaft.

Nope. A suburban has a 129.5 inch wheelbase. The long bed pickup is 131.5 inch...

Re: One piece drive shaft

I think it is where it was built cause my 77 had a 1 pc
but my 91 and 87 both 2 pc
