- 1979 CJ7, 304 with headers, cam, intake manifold, and Edelbrock carb, T-18a, D20, D30, AMC20
Hey y’all, first post and just got my first CJ yesterday. 1979 CJ7 with NO RUST woohoo. I have wanted one since I was a kid and now I’m 37. Happy birthday to me haha.
My truck is in decent shape but the PO couldn’t recall when he last replaced fluids for axles, tranny, xfer case, etc. He had the CJ for like 14 years but only took it out of the garage 3-4 times per year for a night out. So only 1,000 miles since 2006. He did change the engine oil every six months.
Anyway, I need to find out the correct replacement fluids for the following:
AMC 304 (10w-30 I guess, but any favorites? I have used Mobil 1 in my other vehicles is that good for these older engines?)
T-18a
Dana 20 xfer case (Pretty darn hard to shift this bad boy it may be dry)
Dana 30 front axle
AMC20 rear axle
I want to use the highest quality fluids with wide availability. So no Amsoil but you know, good stuff that I can get locally without going on a hunt.
Anything I should do/look for while I am replacing those? I also am replacing the broken front hubs, anything that is a “might as well while your in there” thing I should do? I was going to count the gearing since I think it’s been regeared. 33x12.5s and they roll real easy, and I feel like I am already into 4th pretty soon.
Thank you all for your help! I’m sure this is one of many posts and I really appreciate this community.
