I have an 04' rubi. Running 35 nitto mud grapplers. It's a daily driver for now, I need to re- gear. I have seen discussion on 4.88, and 4.56. I don't take it off road unless I'm at my place in the mountains, but put it together the way I did because I wanted to go where I wanted when I wanted. 90 percent of the time when it's in 4 wheel drive they are pretty tame trails, primary acessing remote alpine lakes.
That basically sums up the off road end of things. Now to the " drag" I have noticed recently that when I let of the accelerator there is a lot of drag,almost as if the brakes are slighty applied, it makes me cringe knowing how hard the jeep is working just to go down the road.
Almost wishing I would have never "messed" with it. Any advise s
Well, I know I need to re-gear, but it's hard for me to think that the tires are causing that much drag. They are a very aggressive tread pattern, but never realized it would be like this. I was curious if there might be a common reason for this or u joints etc etc. My comment tirades re- gearing is for highway, any advise on what gears to go with? Either 4.88 or 4.56?
Did you take your parking brake off????? Haha jk! I am assuming 4.0, either with the 3 speed auto or the 5 speed tranny. Is this "drag" recently been happening or has it been there since the lift and 35" tall tires? Either way a regear is in order and for 35s you should go 4.88 that should bring you back to nearly stock throttle response. You can go 4.56 gearing but then again it would be less ummmppphhhh for the possibility of .0001 more mpg (that's a guestimated non-scientific horrible calculation on mpg difference). I would just stick with 4.88s, oh and by the way with that large of tires and lift its not only drag but a lot more mass your jeep has to rotate just to get down the road. Plus with regearing to 4.56 or 4.88s you should see a 1-2 mpg gain. Hope this helps!!!!
