haha im not fully expecting them to pay for it all, but in all complete honesty if you were in my situation wouldn't you atleast try? I mean, if they wanted to do it right they should have put the proper gears in to begin with...
It's really more about preference, and personal taste, combined with driving habits and terrain driven. They can't setup and sell each vehicle for every new owner specifically. You can order based on your needs and wants, but you bought the Jeep, all the options were listed, and I'm guessing no one held a gun to your head while signing?
You can get a jeep with 3.21, 3.73, and 4.10 gears, in either an auto or manual set-up from the factory. Based on that, what are the proper gears???
It depends on who's driving, where they drive, and what they expect?
Many here report being quite happy with 35's and 3.73's on the new 3.6, while others say you need 4.88's. Some even have the 3.21's and don't mind.
I won't argue with anyone on their preference for gearing, but almost every setup has fans and detractors.
My guess would be that if they installed 4.88 gears @ dealership, we'd be seeing another thread by another new owner asking why their New Jeep only gets 14 MPG...
