basicly what the title says whats the point of a divorced x-fer case. I have a Ford c6 tranny with a np205 behind it mounted directly.

thanks for any info and excuse me for my ignorance

Driveline angles, and using a 2wd tranny.

ButtNuttN8 · 10-06-2006, 05:02 AM

thanks all

You need a long wheelbase rig (like a pickup) to run a divorced Tcase. A divorced NP205 is very strong, but you have to deal with the additional driveshaft, meaning there are more joints that could go bad.

I had an '83 GMC regular cab long box. It had a SM465 tranny and a married 205 case. With the big lift and short tanny/cae combo, the front shaft was short and steep. I think it was about 25", and the rear was like 76". It liked to bind up at full droop and chewed up joints like crazy. A divorced case would have lengthened the front shaft and shortened the rear shaft and probably alleviated the issue of the front shaft. In a longer WB vehicle, they're not a bad option, but ina short WB vehicle (like a Zuk or Wrangler), they're not such a good idea.

well i got a 94 ford f-150 long bed reg cab truck that im doing a lot of mods to over the winter. Switchin to rockwells front and rear so im not sure if i need divorced or not i guess ill have to wait and see huh

Rerock · 10-06-2006, 12:51 PM

I guess the biggest factor for me is ease of replacement. What's gonna be easiest to locate, and which is gonna be easiest to replace when you break? I like to use stock stuff as much as possible so that when something does break, it's readily available. If you can find divorced 205's all day long, go for it. Not saying you'll need them, but if you can get a bunch for spares, why not. It's still a 205.

Jmudder79 · 10-07-2006, 04:44 AM

I think a divorced id eadier to replace than a married t-case. You don't have to worry about splining up the trans to the t-case or keeping dirt out of inbetween them. You just undo the d-shafts, undo the couple of bolts holding it up, and drop it down. With 2 people changing out my married case compared to my buddys divorced case, we can swap his out in a quarter of the time we can swap mine out.

If you're going Rocks front and rear, you shouldn't have driveline angle issues due to the pinion locations on the diffs. I'd stick with married as it involves fewer parts and makes for a cleaner install IMO.

TAWL_BOY · 10-07-2006, 10:49 PM

would the driveshaft between the tranny and divorced case have to be perfectly straight our could the u-joints have a little bit of and angle to 'em? I'm building a swamp truck and it would be nice if i could drop the case down several inches.

I was also going to run it behind my stock t-case to act as a doubler. Would I need a SYE or would the slip yoke be ok.

They can have a bit of angle.. it is actually a good thing , keeps the needle bearings in the joints turning. just make sure that the yokes are paralell with each other

*edit... my little illustration didnt work out too good...

Not that much of an angle obviously , but keep the yokes in line.

I would do an SYE , but you can run it as is.

are we thinking of the rockwells with top loaders (diffs on the top of the axle) and forgetting about the rockwells that are liek any other axle, diffs on the side

if your rockwell has squar tubes then its a top loader witht he diff on the top of the axle, if it has round tubes it has the diff on the side

ButtNuttN8 · 10-08-2006, 07:42 AM

yes the one im looking at are deft top loaders

No, I have seen many rockwells with square tubes that have diffs on the side.

Probably because of the short driveline legnth they needed to legnthen the front d/s.

another good thing about a divorced case is u can mount it to make both your drive shafts the same length so then u only have to carry one spare.

it was a joke. and you must be kidding, the front driveline is way longer in a samurai than the rear. the rear should be the longer one.
