Driveshaft question

[70jimmy]

I am neck deep in my doubler install. the 205 I purchased with the doubler setup has 1410 U-joint for the rear output on the 205 and a flat flange with 4 bolt holes for the front output. My old one was u-joint front 1310. so which is better, CV or u-joint, pros and cons.

With the doubler I will have even less angle on the front shaft than before so either would work.

On the rear I am betting I will need a high angle type CV.

So if it was yours would you go both CV shafts using the 1410 for the rear and flange for the front??

I was using flanges on both front and rear and like them a lot. They are easier to unbolt and re-bolt for some reason if you need to replace the shaft. The drawback is that they seen to take up slightly more length than the other style so may not be as friendly to short drivetrain lengths.

I also converted everything to the same size joint 1350. Having the same flange and joints on front and rear may make it easier to swap parts around if you ever had too.

I run 1350 cvs on both sides of the doubler with the 4 bolt flanges and 1410s at the axle. I agree they are pretty easy to get on and off. Mainly though I wanted them the same because then I built a square Drive shaft as a spare. With the square it can have tons of slip so it will fit front or rear. It only has a 1310 cv, but flange is the same and it was free. One thing on the flanges is I've had the bolts come out and leave my drive line hanging on the cross member. So now they still get the red loctite but also have a jam nut on the backside. I like running the cvs to help make up for my not perfect d lines. Ive changed my truck around and had to lengthen and smoked a few lines. Got tired of paying to get them tubed, so started building them myself. The last 2 i could comfortably do 65mph on pavement. Just finished the last one and went with 3". 120 wall dom, with my old original cv still. Which ever route you go i just suggest making them the same for the square spare d line. 1350 cvs can be had on a number of trucks from the boneyard. Mine happen to be dodge ones, ford used some too and also used the 1410 at the axle on some super dutys.

I am same as ssyork, 1350 double cardigans on cases and 1410 at axles. If I were to do again I would do 1480 single joints throughout. I made a yoke for my tcase and spare shaft using broken d60 stubs. They operate at more angle and same joint as 60 shafts.
