1 Ton Axle swap

[mil_act02]

I just bought a D60 and 14FF for my Jimmy. Need to know what to do about driveshafts. Can I use the stock driveshafts? Do they have to be shortened? What else would be involved to make them work? Should I just wait until I can afford some custom driveshafts?

i put the 14 bolt ff in the rear and i think the drive shaft needs to be lengthened. i did put a lift on it. have you done a search yet

somone said that it's better to have a lift because the yoke on the 14bff is longer than the old 10bolt , i dunno ...i measured and they seems to be the same length

havent checked the D60 yet

I put my 14BFF in along with 5 inches of lift. The stock driveshaft works fine, just needed a conversion u-joint from napa.

if you measure from the frt cover back to the tip of the yoke it will be a bigger distance to them on the 1 ton axles. and a small lift will be better and help alot . and like above a trick joint at the rear only for the drive shafts to bolt up. good luck.

I have a 6" lift already so I might just need the special u-joints.

On my 71, the front bolted in, the rear was another story. Then again, the truck came with a 4 inch lift, so I have no idea if the shafts were stock or not.

Can you use that special u-joint for the front? Also what did it take to install the rear?

 

[sweetk30]

all frt joints should be 1310 at yoke unles some one has changed things.

Thanks for the help.

i went through a headache.
i was 1/2 ton and put on my suspension lift. then had my driveshafts built.
then i went 1 ton. I'll bet my 1410 rear yoke and 1350 front yoke have something to do with my issues.. my rear came up too long and i needed to use my 1" offset holes in my spring perches to make my driveshaft work. for the front, it was too long as well. i had to shorten it. yep after i legthened it a few years before for the lift. I'll bet the stock driveshaft woulda been perfect.
