Am trying to find out what my best choice of changing gear ratios in my 2000 TJ. I have been looking for some Dana 44 axle assemblies with 4.56 gears. I have also checked into swapping the gears in my 30 and 35 axle assembly. 4 Wheel Parts said that they could do a gear change in my axles for $1800.00. Any help would be greatly appreciated.
