Keep braking my drive shaft

[muddflow]

Hey guys sorry to bug but, need help. I keep braking my driveshaft(u-Joints) of my 73 1/2 ton blazer. I have an 8 inch lift with 38s. Im guessing thats why Im looking for a 14 boltFF but haven't found one yet. until i find one at a decent price what will i have to do to run my 12 bolt. thanks in advance

Have you measured your driveline angles? Sounds to me with the lift that you are just killin your joints then the 38s are taken em out.

Which end are you breaking it more at? The axle u-joints, or the transfer case u-joints? Is it the front driveshaft or the rear?

at first it was the on at the axels then just the other day the on from the trnsfer case broke

Should I try droping the trans. a little bit
sorry the rear

Yeah, your driveshaft angles are too steep. Another thing you could try is rotating the axle up, and that would require modifying the spring perches.

is there any pads(shims) something like that i could use? My front axle has some shims that really change the angel.

Thanks for the helpful imformation everyone.

What about the 12 bolt? should i be good for a while? after i change the angles. Or should i just wait 'til I get the 14 bolt
