Q: Swapping differential fluid--which one to use

asked by on

96 Jeep Cherokee 4 L needs to swap differential fluid Dana 30. The manual says to use 75w-90. Do you think I should use synthetic 74-140 instead because I'm often on road?

Yes, you are going to get more protection that way. If you are on the road a lot and there is a lot of strain, do it. It's a better oil. If you want to have a technician change the oil for you, YourMechanic can provide the correct oil and perform this task for you at your home or office.
