changing diff fluid

about to change the diff fluid on an 84 cj7 but the thing seems to be sealed. maybe a dumb question but a little insight would be greatly appreciated. oh and also the heater core seems to be leaking antifreeze into the passenger floorboard, maybe someone has some experience with this as well and can offer their help

thank you from the "newbie" aka Scott

You have to pull the cover off to change differential fluid. The heat core will have to be replaced if it's leaking. Get yourself a Haynes/Chiltons manual for you Jeep and it will get you started.

Anything is possible if you don't know what you are talking about.

My heater leaked too. I just need to tighten the two clamps on the heater hoses.

When my heater core started leaking on my 86 I just bypassed it. Easy to do when you live in TX. Wasn't a daily driver though. The cab used to get plenty warm from just the heat coming up from the floor and the Tranny hump.

OR you could go spend 20-40 bucks on a new one and put it in and have a heater and defroster. It's not difficult. There's a few screws in the firewall holding the heater assembly in. Take those out, take the back off the duct, pop the new one in, reattact the hoses and you're good to go. I agree about buying a manual.
