Re: Black Diamond Suspension Lift Installed-questions
Full droop would shorten the drive shaft on a suspension like that, wouldn't
it? I think the t-case output is lower than the frame-end control arm
mounts. I'm pretty sure my drive shafts are compressed when the TJ is on a
lift as compared to when it's sitting on it's wheels, even with the raised
t-case skid.

Re: Black Diamond Suspension Lift Installed-questions
No. Your pumpkin end is lower than your xfer case end. If you droop the
axle, it moves further away from the xfer case output shaft and becomes
longer.

Re: Black Diamond Suspension Lift Installed-questions
But, when the axle droops it doesn't drop straight down, it moves though an
arc. The length of the control arms is fixed, so the whole axle assembly
essentially pivots around the frame control arm mounts. Given that, if the
transfer case output is lower than this pivot point, the driveshaft is going
to compress.
