Can I flat tow my wrangler with different gear ratio

I just bought my 1994 jeep wrangler. The previous owner changed the rear axle to a Dana 44 and didn't change the front gear ratio on the stock Dana 30. My question is if it's ok to flat tow my jeep like this until I get the money to fix it right.

Pull the front driveshaft and its not an issue. Never flat towed my old yj so don't know the particulars to it. Never pulled a shaft either so take that idea as just an idea.

Your post is confusing. Are you saying that the front and rear doffs have different gear ratios? That means you can't drive in 4wd. You know that, right?

Has no effect on flat towing though. Just put the transfer case in neutral.

Yes, the front and rear diffs have diff gear ratios and I know that I can't drive in 4wd. I just want to make sure that I can flat tow it and drive it around town while I'm camping without any problems as long as I'm not in 4wd. Thanks for the replies.

the YJ front shaft only spins when engaged into 4wd so all you really need to do is put the jeep into neutral ive flat towed my old YJ all the time (broken ) of coarse lol you will be fine.

That is not always true.

On most YJs (not sure if there is a cut off year) When the transfer case is in neutral the drive line is disenganged from the engine power BUT the front and rear are connected and will both turn together. This becomes a huge problem when trying to flat tow while having an aussie or other lunchbox locker in the front.

Check this thread for my issue, the explaination and the cause start in post #12.

I don't have a locker on the front or the rear so will it cause a problem flat towing with different ratio? And what gear do i tow the jeep in or do I keep it in nuteral?

Chances are you will not have any issues.

The instructions in the manual say to put the tcase in neutral and the transmission in park or 1st.

Personally I would disconnect both drive shafts from the axle end and strap them up out of the way. It will only take a couple minutes and remove any chance of problems. I did that every time I towed up until getting a tru neutral plate installed.

You can get one of these transmissioon stop off plugs from Harbor Freight for the rear unless you have an SYE installed.

Don't forget to unlock the steering wheel.

Now that is pretty darn interesting that the NP231 connects the driveshafts but not the transmission when in neutral. Just when I think there is nothing left to learn.

But, I think there will be a problem for the OP if the ratios are different. When the np231 joins front and rear, they are not spinning independently like axles on a diff. They are actually connected as though it was in 4wd if I read your references correctly. So to my thinking he has to put it in 2wd and the tranny in neutral assuming it is not an automatic which will burn up from no fluid pumping.

So if I disconnect both drive shafts and strap them out of the way do I still need to put the transfer case in N and the trans in 1st to tow it? Thanks guys for all the help.

No if you pull the drive shafts you can do whatever you want with the transfer case and transmission

So if I get a tru neutral plat installed I don't need to put the tranny in gear or i wouldnt have to worry about disconnecting the drive shafts?

With the new plate you put the t-case in neutral and the transmission in gear, or Park.
