Hey All - Changing the diff fluid in my kid's 89 Comanche that is a bit of a Frankentruck. It was converted by someone else to 4WD when we bought it. It's got a Chrysler 8.25 in the back, which I've never worked on. Is this a track lock diff? I jacked both wheels up and when you spin one wheel, the other goes in the same direction. So definitely not an open diff. (Can't seem to post attachments, so hopefully you can see the photos here: https://photos.app.goo.gl/6uLK3ZJG6ryCJwbX9 )
One other question that may sound a bit nuts. We installed a Lokka in the front Dana 30 about 2 years ago. I could have sworn I read 4.10 on the ring gear. The rear ring gear is clearly a 3.55. My kid has been having drive line issues. Vibes, blown U-joints, on the driveshaft. Is there any way that the truck would even drive in 4WD without it tearing itself to shreds with 2 different gear rations like that? I'm going to have to pull the front cover off again and double check.
