    Hey everyone, it's about time to change my differential oils and I wanted to see if 75w90 full synthetic is good to use for both the front and rear differentials especially since I have the ECGS bushing installed for the drivers side needle bearing.

    Thanks for your help!

    I have EGCS bushing in mine. They recommend Lucas 85W-140. Bottle looks like this.D86C6FE1-0F93-43E9-A6A6-8C3B5A4BE4EC.jpg

    Awesome thank you, I'm assuming it's the same for 2nd and 3rd gens right?

    Don’t use 140 it’s too thick for stock diffs. It will increase likelyhood of seals popping.

    The bushing doesn’t change anything, just use a quality gl5 oil.

    typically 75w90.

    Yes. Use your favorite
    $29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)
    75W-90 in the rear diff and in the transfer case. So a little extra work because of the unique oil in the front diff. All are easy to change. I just refreshed the fluid in all 3 on my 2nd gen.

    edit - I’ve had no seal issues in the front. Simply sharing what EGCS advised me to use. I’m happy with their recommendation.

    Sweet, thank you for the help. Makes it a whole lot easier being able to ask others that have experience vs what a manual or website says.

    Anyone switch to conventional oil? My conversation with ecgs over the phone earlier suggested that the oil being conventional was more important then it being 140w
