4.0 Automatic Regear
I am looking at an 06 LJ with the 4.0, auto, 3.73 gears and 35's. If I was to regear for the bigger wheels, what gears would be good for this setup? Will mostly be a backroad, light trail machine. Some daily driving(no interstate driving). What are good brands to look at? How much work is this job, and how much$$? TIA!
You have the 42RLE transmission which has a very steep OD and computer that does some odd things. Realistically for 35s you want something in the high 5s, but your front D30 is going to limit you to 4.88. That's about right for 33s with that transmission and is at best OK with 35s. Gear setup is something that most people on JF leave to the professionals. Its doable by the average person if you have time, are patient and pickup a few specialized tools. Really depends on you. Typical cost for regearing both axles would be in $1000-1500 range depending on where you live and the shops you talk to.
I would lean to the 4.8w/35's with the .69 od ratio. cost would be around 1300 to 1500
