Different Gears In Each Axle (Temporary). Remove DS or Just No 4WD?

I'm re-gearing my rear 44 this weekend to 5.13s. I have a front Dynatrac PR44 on order that should arrive in a few weeks, so I'll still be using my existing 30 with 3.73s until then.

Is it necessary to remove my front drive shaft or would it be okay as long as I don't just use 4WD? To my knowledge, the front driveline is fully disengaged when in 2WD and I wouldn't have any issues. I just wanted to confirm that that'll be okay.

no 4wd will be ok, unless someone else may drive your jeep in the mean time. your abs and stuff may go crazy, might want to unplug a sensor to get it to turn off. it may not though. although yoll need to disconnect drive shaft anyway to put in new axle so you can just take it out now

I'd yank the front shaft for safety. You can't use 4x4 with that setup, and you're going to have to pull the shaft for the PR44 install anyhow. Your ABS/ESP/Traction control will work fine since it gets it's reading from the wheel speed sensor. Which is not altered by gear changes. All 4 wheels will spin the same speed regardless.

No 4wd, but I'd pull the shaft to keep from an accident.

It'll be fine as is and shouldn't mess with the abs since the sensors read at the wheels.

31 jeeps in... still have issues

Thanks, guys. I'm thinking I'll keep in it for now, at least the weekend. I'll wrap the transfer case shifter with a plastic bag or something.

I've driving for several months with different gear ratios between the front and rear axle without an issue but like others have said its a good idea to go ahead and pull the front drive shaft.

Although leaving the shaft in place will not do any damage as long as you don't put it in 4wd, why not yank out your DS now and save yourself the extra step later on when you'll be wanting to install the new axle quickly.
