I have started looking into seals and gaskets for my raider. Front and rear. When I weld up my gears I might as well change the seals and gasket while I'm in there. Only problem is I can't find the correct seals. Or gaskets. Could be that I am not really sure what I need. Where do I need to look and what do I need to buy?

Are you talking about the differentials? Did you look in Rock auto? Are you talking pinion seal?

My seals weren't leaking, didn't mess with them. Any surface that used a gasket, just used silicone.

I bought m rear axle seals from EBAY, took a chance and they were the right ones, I have the spanner wrench and plate to remove rear axle bearings also.

What I do when I'm not sure what I'm getting into before taking apart something is look at both the FSM and ASA/Caps tool that are found at Mitsubishilinks
You can look up the part numbers found in ASA at a lot of places like rockauto and napa.
Looks like two seals on the right side and one on the left for front axle plus the pinion seal.
Two seals per side on the rear axle plus one o-ring per side and the pinion seal. The pinion shaft nuts are not suppose to be reused either. Would help you with the PNs but my V6 may be different as the diffs are a different size. I would use rtv on the carriers and diff cover. They have a blue rtv for cold temps, haven't tried it myself but haven't heard anything bad about it. Either way letting it cure overnight before refilling the diff can't hurt.
