Title: combining axles
Post by: Dave69 on January 30, 2009, 07:17:17 PM
using a permenant 4wd transfer box

would it be possible to drive a jeep in 2wd with the front propshaft connected without causing windup issues. the rear axle one ratio and the front a different ratio.

or does the front propshaft need to be disconnected.

IN 2wd then there wont be a problem cause the prop is disconnected from the transfer box internally.

:imwitstupid:

But I would remove the front prop anyway, it only takes 10 minutes

If you've a perminent 4wd transfer case how are you going to select 2wd?

If it's a selectatrac then you'll need to use the semi 2wd mode. If it's a quadra track, don't drive with the front prop disconnected, and both axles need to have the same ratio gears in them, else you'll cook the transfercase.

you need to pull the front prop off, otherwise you might do some serious damage.

are you changing the front too???

if its on something like a ZJ perminant 4wd you should be fine pulling the prop off cos its a viscouse coupling an just puts all the power to the back.

i know cos i have a tail happy jeep again :lol:
