    New to posting. Sorry if repeat. Where transmission meets engine. Oil leak. I guess that’s rear main seal. Any tips, advice, cost analysis. Appreciate any direction.

    That is easily the funniest misspelling of mechanic I’ve ever seen. Thank you. And ideally myself.

    Automatic. Do I need to remove driveshaft and transfer case as well?

    Up to you but the trans has to come out unless you want to do the engine.

    Make sure your valve covers aren't the real leak.

    X2 on valve covers. I bought my 01 last June with what I thought was a badly leaking rear main. Even bought it with the leak projecting to spend $800 for the dealer to fix it. Most of the oil accumulated right where you are speaking of. Ended up changing the valve cover seals and there isn’t a drip of oil anymore.

    I highly suggest checking that before going into the rear main replacement, valve cover leaks are notoriously deceptive.

    Same here. Saw dripping from main seal, but my mechanic said it was coming from rear cam plugs and oil cooler assembly.

    We should make a sticky on chasing oil leaks, I bought my truck new, replaced valve cover gaskets at about 8 years, then had to do it again because I did not know about the cam plugs (not in that section of manual). Then oil cooler, then oil filler cap, then front seal. Also, oil dipstick oring. Mt truck was never oil free until I did all of these within a few years of each other. Of course the front crank seal would only be done as part of timing belt. The rear seal has a spring to maintain contact with crank so probably lasts longer than most seals.

    Almost seems like no matter where the leak is, the oil is blown back onto the rear and ends up on steering rack and even on the trans.

    Definitely do these as much as possible all at once because likely they are are all leaking to some extent if not done in last 10 years.

    Yea first check to make sure the valve covers are not leaking or anything around there.
    If it is the rear main seal i would suggest you remove the transfer case. IMO it makes revoming and reinstalling the transmission much easier. Have a transmission jack will also make things way easier.
    good luck
