I need to get a drive shaft for my 1991 V3500 Crew Cab 3+3. It has a 2-piece drive shaft like all square body crew cabs, and all of the operating angles are correct on the drive shaft except for the rear drive shaft right at the carrier bearing slip yoke. It has a 7-degree operating angle at the carrier bearing slip yoke, and causes a vibration at 25-MPH and 45-MPH. I need a Double Cardan H-yoke at the carrier bearing slip yoke, but nobody seems to make one for this type of application. I have talked to Tom Woods drive shaft, and they say that they do not make anything for a 2-piece crew cab drive shaft. Does anybody know of a solution for an old square body crew cab 2-piece drive shaft. With all the lifted square body crew cabs that have been built over the years somebody has had to come with a solution to this.

I talked to a guy A Denny's drive shaft, and they have a flanged slip yoke that a Double Cardan flanged pivot bearing will bolt too. they said I have to maybe modify my spline shaft at the carrier bearing so it is not keyed, in order to except a non-keyed slip yoke. They also recommended a urethane carrier bearing bushing so the carrier bearing can handle the extra weight of the Double Cardan joint.

I assume you have looked at @mrk5 setup?

I use Driveline Services of Sacramento, they pretty much do it all and have even handled same day lengthening service to one of my shafts. http://www.dlssac.com/index2.php

I looked at his profile page, and I see no media on his driveshaft. I am going to have a company here in Las Vegas called Dan's Driveline do the drive shaft itself, Denny's Driveline is one of the few (if not only) companies that has the flanged slip yoke to attach a Double Cardan joint to it.

Actually I think I did see mrk5's drive shaft. It has the carrier bearing on the top side of the cross member instead of the bottom side. He had to build a custom cross member for that.

look at his build thread, lots of talk about his rear shaft :insert joke:
 
How much lift do you have? What's the drive train? I drive a 1991 V3500 crew with 4 inch ORD shackle flip and have no issues with my stock 2 piece drive shaft. No vibrations at any speed. SM 465, NP 205.
 
Have you considered spending a few extra bucks and having a 1 piece aluminum driveline made? I know it's a different truck, but a lot of the new stuff has gone to a 1 piece alum. My '06 Mega cab cummins has a 6" lift and the original 2 piece was giving me vibs. I replaced it with a later 1 piece aluminum and everything was considerably smoother. Looks awesome too, it's like a 6" tube.

Dennys is pretty good. Very reasonable on price as well.

Another vote for sac driveline. Ive gotten a drive shaft from scratch in 24 hours from them lol. Good stuff.
 
Mine came from High Angle Driveline. It's a 1410 double cardan. Instead of a slip yoke it uses a flange at the carrier bearing. I like that better.

It has a slip yoke on the shaft down by the axle which I also like better for 2 reasons. One, it is smaller diameter so more clearance and second it is a replaceable part that doesn't require a bunch of driveshaft work.

No vibration and my rear shaft is at about 12°. Negative side is it's not a cheap option but I think a 1350 would possibly save some money and work well enough. Plus I had him build it with 3". 120 wall tube which you may or may not need.
 
Dennys has built a couple of shafts for me years ago and I bought some driveshaft parts off them this year. They are a quick and trouble free company to deal with.
One other reason I went with them is they are some what close to me ( Next day ship ) That's one thing you need to look at. Not only shipping cost to get it, but what if something happens and you need to send it back?
I've also have gotten shafts off HAD 12 - 13 years ago and are still running them today with zero issues ( Except ones made by me changing wheelbase and had to shorten the rear one )
I've had some work done by local shops with mixed results, always seems to be a

My 1991 V3500 has 10" lift in the rear, and has the 4L80E with 205.

I looked at your post on your drive-line. Yours is the ultimate way to go. If I where replacing both the front drive shaft and rear drive shaft I would have mine built the same way you did yours. But, since my truck is only having a problem at the rear drive shaft, I am just going to fix that, and go with the factory slip yoke at the carrier bearing double cardan fix. Some time in the future I am going to do that same modification you did of putting the carrier bearing up top instead of the bottom. With that carrier bearing hanging down it is just begging to be ripped off.

I understand now. 10" of lift is a lot, I bet you need that double cardan pretty bad. Nice looking truck!

I couldnt think of any reason mounting it up would cause a problem, but I often wonder why the factory does things the way they do.
