What year and model? If non rubicon you will have a 30 front, rear could be either dana 35 (plastic plug) or dana 44 (metal plug).

It doesn't matter which model they are as there is no 'seal" in them. They are sealed with RTV silicone.

Pull the old cover off. Start with the bottom bolts and let the oil drain as you remove the cover. Clean out the cover and inside of the diff with some brake cleaner. Scrape all of the old RTV off of the cover and the diff housing itself. Make sure everything and both surfaces are dry and clean. Sqeeze a new bead of RTV all the way around the mounting surface of the diff cover. Make sure you get it around each bolt hole. Let it dry or tack up or a couple 3-5 minutes and them re-install it. Torque the the bolts to 25 ft/lbs. Refill the diff with a quality oil.

But they both have pinion seals and axle seals. Which do you want to replace?

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.

Sounds like a good excuse to throw on some sturdier diff covers!
There's a big brown van somewhere with 2 Riddlers on the way to my doorstep as I type
