Can you regear just the rear axle?

BIGNUTT · 12-16-2005, 07:10 AM

I just lifted my XJ and I have a guy thats gonna install 4.56s and a powertrax no-slip once I get the mone yfor labor. Well I am HATING driving on 3.55s and 33s so I wondering if I could go ahead and regear the rear as long as I keep it in 2wd? I may even take the front driveshaft off so no mistakes.

Would this work till I got the $$ for the front? I just see 80 miles a day and can't take it on the road, lol.

But it will be okay? I have an nv242 if it matters, I'll just keep it in 2wd and take the front shaft off.

u will be fine i ran 33's on the rear and 28's on the front with nogears in the front and a locker inthe rear

Just remember : NO DRIVESHAFT

Now I will still have my 3.55s up front.

As long as the front axle is not engaged you are fine. Don't shift the transfer case into 4Hi or 4Lo and/or remove the front driveshaft.

There is absolutely no need to remove the front driveshaft with two different ratios, you just have to make sure everyone who might drive it knows not to engage 4wd.

I was under the impression that the t/case was syncronized, since it allows shifting to/from 4HI while driving. So in this case the front driveshaft would be spinning at a different rate than the rear... but that doesn't matter?

The front driveshaft spins only because it is connected to the axleshafts through the differential. The transfer case gearing is disconnected from the driveshaft when it is in 2wd, it has a true 'neutral' for the front driveshaft connection when in 2wd. At least since around '96.

Doesnt matter accidents happen. And the front of the case does disconect.

One skip in train of thought will -=-=-=-= that case.

I understand that part, I just thought it might screw up any syncro parts in the t/case that keep the gears ready to mesh when you pull up on the lever... I guess that doesn't happen until you actually pull the lever then?

I know what everyones saying, lol.

I will take the ds off, I get absent minded sometimes and I (obviously) don't have the cash for a big mistake.
