Hello,
I am in the process ofpurchasing a 2002 Durango SLT+ 4X4.
I test drove it last night and gave it a look over. Decent vehicle.

I have a quick question.
What is the correct operation of the 4wd system. I wanted to test that but was a little confused. It is the push button style Awd/4wd system.

First: Do I need to stop the vehicle to put it in 4 LO. Does it need to be in PARK or NEUTRAL?

Second: Is this a 4 way limited slip arrangement or is it a posi in the front and rear or what? A google search turns up little of value.


Thanks for any light you can shed.

1. you DO have to be stopped to put it into LO.. well correct procedure is rolling about 2mph in neutral

2. second question there is a lot of controversy over.. I will say what I think, but I'm sure I'll be corrected, or possibly backed up.. The front diff is Open, and the rear is either Open or Limited slip (check the sticker in the glove box)

 

WKC:

If your dash switch is marked AWD/4hi/4lo, you have the NV244 transfer caseIMO is a gem.

Normal state is AWD, so you have power to both front and rear axles all the time. 4Hi can be engaged up to 55mph. As Deerang said, 4lo seems to engage easiest with the tranny in neutral and rolling a couple mph.

Since I swapped my part time case for a full time case back in Feb. of 2007, and had not had to use 4hi since. The MPG difference between the two cases has proven to be negligible.

From the factory, your front axle has an open carrier. You can verifiy this by getting under it and looking for a white label on the housing which will say either 3.55 or 3.92 open.

The rear axle housing will have the same type of sticker behind the driver side tire. If the sticker says Anti Spin, you have the LS carrier. Otherwise it will say Open also.

n8ech, deerang,
Thanks for your replies. The info was very helpful. I have owned 4wd Toyotas before but this is the first dodge.
It does have the AWD/4Hi/4Lo switch. I have not checked the diffs yet.
Thanks again.
Kevin
