205 front output seal

Can someone tell me the part number for the front output yoke on my 205? It is in my 72 blazer with a th350. I went into napa and they told me I need a number, there books only go back to 91' and the computer isnt showing anything

Napa is the best in town for knowing what the hell your talking about. i would pull mine out to check, but I am driving it every day and cant risk them needing to order it in.

While I am on it, is it as easy as unbolting the yoke and slapping the new seal in and running the nut back on? Are there torque specs or anything else I need to know before jumping in?

i will get the ### for you tommorrow but there is no torque or anything you can screw up, just run it down hard and that is it.

stop by your local tranny shop, they probably wont charge you more than 10 bucks for both parts, and smile while you walk out... with the right parts in hand.

I'm going to be replacing the front output shaft seal on my NP205 pretty soon as well, I've never done it before so I am curious about this as well, is it as simple as dropping the driveshaft, unbolting and removing the yoke, removing the old seal and putting the new one on and then putting it all back together? I'm going to do a search for an exploded parts diagram of the 205, as they say, a picture is worth 1000 words, but any extra info or tips on this repair would be great.

Thanks again guys.......Got to thinking though. the last time I went to check the t-case level a ton of atf poured out So I might as well replace the seal between the transmission and t-case while I got the t-case emptied out. Anyone got the number for that seal? Its gonna be the same story going in on that one too

Its that simple, just make sure you got the gasket or make your own.
