longer drive shaft

[jsfordboy02]

When I put on my 4" suspension lift, will I need to lengthen my drive shafts? My front is a solid but the rear has a slip spline. I don't do any real extreme off-roading just some weekend wheeling.

No. I am running a 6" lift on my Bronco II without longer driveshafts. I have used my BII pretty good without any problems. There is more than enough in the driveshafts for up to a 6-7" lift.

If your rear driveshaft has actual u-joints on it, then you should be fine.

? Actual u-joint? As apposed to what? (I'm not trying to be a smart-ass, just a little confused)

Some of the older Rangers and BII's had a CV joint driveshaft that wasn't real acceptable to lifting.

Yep, the POS dual-CV BII rear driveshaft (has rpezza (sp?) CV joints) goes real quick if you put any angle on it over what's stock (they don't last all that well even at stock height either). I believe '84 was the only year to have a u-jointed factory driveshaft, although the 1210 u-joints are real tiny on them.

I run a stock FRONT driveshaft from an Explorer (cut down) on the rear of mine, it has larger 1310-size joints, and has a standard double-cardan CV at the t-case end.

Gottcha, I had no idea Ford would do something like that, but I guess nothing really surprises me at this point.

An example of a Rezeppa type joint can be found at
the T-case end of the front driveshaft in a Gen4 ('98-up) or later Ranger.
or in 'mid-96-up Explorers.

the "rezeppa" type joint is a "six ball and cage" arraingement similar to the Outer CV's used on most FWD vehicles.
However the Rezeppa doesn't tolerate quite as much angular displacement, because it's design is a compromise between high angles and the ability to tolerate a small ammount of "plunge" travel.

thus rezeppa joints are commonly found at the inner end of
front driveshafts on european FWD cars (VW, Audi and on
the REAR of Mercedes and Porsche)

the last CVtype Bronco2 driveshaft I took apart used a "tripod"
bearing that are also commonly used at the inner end of driveshafts
on powered independent suspensions.
