k series front driveshaft help!!

[special-K]

I guess you have bad luck. I have been running lifted 4wds with 37" tires since 1977 and have never needed to repair a double cardon joint. I have broken axles,u-joints,ring & pinions,and even peeled an intermediate drive shaft in two in a divorced trans/transfer case truck. Why do you think serious 4-wheelers install them where they weren't by the factory? Because it's better. Why do you think world class driveshaft specialists make double cardon set-ups? I dunno,I'm a hard head and see things how I see them no matter what anyone says. So,I understand if you still think you're better off without a double cardon. But,I also do listen when those with vast experience offer advise and you did ask.

I like the double cardon style joints, but on two occasions I have had them fail,and when they do fail, they are kind of a pain to fix. Both were on the front driveshaft on my 78 bronco. I also found that the front drive shafts for the 78 79 f150s and broncos were the same as the shafts on 67 72 chevys.

I have to agree on this..I've had the double cardon joint an many rigs and never had one fail. The only ones I've had trouble with are the ones on used rigs I've bought that never saw any grease. If they go too long without grease in the center ball socket it will ruin the centering yoke..and that runs about 50 bucks.
I get the 2 Spicer joints and the centering ball and seal kit here for under 100 bucks... add the centering yoke for 50 if ya need it and thats 150 bucks top and there not that hard to rebuild. Theres just not anyting else in there to get hurt unless the H yoke is getting beat on somehow.
