I have an 89 YJ 3.5" lift 31" tires with D30/35 with 3.07 gears. Bought D30/35 from 93 4cly, 4.10s. The problem I have just noticed is that the 89 axles used 3 vacuum lines to work the shift acuator for front axle. Two yellow hoses, one green. 93 has only 2 lines and a wire running to the motor. I did not see the 93 Jeep to investigate. Can I use the axle with this shift motor or should I switch the vacuum shift actuators? Are the axles the same beside this?

The axles are the same, just switch vacuum actuators.
The '89 used vacuum to the firewall to activate the 4wd light, the '93 used the electrical plug to activate the 4wd light.
