    Hello,
    I have a 98 Tacoma 4X4. I recently noticed a pool of oil under my rear end. I am assuming that its the pinion seal. She has about 250K on her, so this isnt too shocking to think the seal needs replaced. So I go to the autozone website to see what a seal is going to cost. I found 2 different ones for my truck. One says its for an 8 1/4 inch ring gear, and one says its for 6.7 inch ring gear.

    Is this simply the differences between 2 wheel drive and 4 wheel drive rear ends? If not....how do I know which one I need to get? It is wisest to pull the old one out and take it with me?

    The seal for the third member right? If you don't have the locking diff I believe yours is the 8.4 diff. I just used rtv grey instead of the paper gasket.

    Is it coming from the pinion or were the third member bolts into the housing? If it is the later just use RTV, I use The Right Stuff by permatex, works awesome and is way better than any paper gasket. If it is the pinion seal make sure you get a good seal like a national seal or direct from Toyota. As far as what you have if it is a 4wd without trd locker than it is the 8.4.
