Ok, so let me start this one off by saying that I am not very knowledgeable about gear ratios and the like so hopefully some of the "gear head" jeepers out there can school me on this one.
I just picked up a 91 YJ with a 4" lift and 35" MTs on it. The jeep basically has no power in 5th gear and struggles up hills on the highway in 4th.
From what I've gathered I need to have the ring and pinion swapped out and 4-10s seem to be the best for a daily driver. I would like the best middle of the road for power and economy on the highway and yet still have enough low end to get through amateur off road stuff (mud snow etc.) I don't plan on rock climbing or anything like that.
My questions are this;
1. Are 4-10s the way to go?
2. Can someone give me the layman's version of what needs to happen to my jeep to accomplish this?
3. How much can I expect to pay to have this done by a professional?
4. How hard of a job us this? Could myself and a wrench turning buddy accomplish this on a Saturday or is this varsity level mechanics???
