This will be my first try at changing my differential lube. The year 2000 Jeep service manual I have says to use "flushing" oil to clean out the case.
What's flushing oil?
I have the special friction modifier additive for the rear diff and Quaker State synthetic SAE 75w-140GL-5 and silicone sealent.
I was hoping I could cheat a bit and not remove the diff covers and pump out the old oil (suction gun) rather than break the existing cover plate silicone seal.
Any comments on this procedure please advise me.
Also how do I remove the old silicone sealent from the metal surfaces.
only makes the layer thinner but never actually removes the glue.
Any tips or tricks would be much apreciated I was hoping I wouldn't get lub running down to elbows like when I changed the oil in the manual transmission.
