Where do I find out what gear ratios my 97 and my 02 Jeeps have? In my other 4x4 it is in the door on a sticker. :confused:

Since this is a newbie question and I'm a newb I guess I'll answer. Crawl under the rear of the Jeep and there is a tag on the diff cover that will have it on there. If you have a stick and a D35 it will most likely be 3.07, if you have a D44 it will be 3.73. Don't know the auto ratios. This is assuming the gearing is still stock.

If it is the 4-banger with 5-speed you have 4.10's, pretty sure the 4-banger auto has 3.73.

It has a I6 and an auto.

both do

Your best bet is like what was already said,....crawl under and look at the tag.

I opend a dana 35 with the bild paper and ax tag = 3.75 but the damn thing had 3.55 .... and jp build up on there dana 44 was a open carrier but jeep says they did not put in a open in a 44 so the best way is to open it up and count the R & P... my $0.02 :flipoff2:

If you don't trust the tag you can jack up the rear end . Spin the tire and count how many drive shaft revolutions it takes to turn the tire. If you mark them both you can get a good idea of what ratio it is.
