Yup, they ditched the problematic disconnect in '92 in the XJ coil link
suspensions. They didn't bother investing the same change for the YJ's
leaf-sprung Dana 30 knowing it was a dead duck soon to be replaced by
the XJ coil link Dana 30 in the TJ.

Re: Unlock hubs in 94 Cherokee
 

That still has absolutely 'nothing' to do with unlocking the front
hubs!!!!

That is the t-case binding up. It happens on my dana set up too because
of the high traction muds I run.

I thought the real bad set was the 410/411 splits on some of them.

The best work around it to hit 3000 rpm and let off the gas for maximum
vacuum.

Going in reverse has 0 effect except at the idle point when the vacuum
comes up because the transfer case is already in 2 wheel drive so the
driveshaft is loose already.

Yup, that's it and that's enough not to be able to release four
drive in just a couple of feet after getting up on the road.
