Transmission output shaft seal/bearing

[diezelraccoon]

Have a 2003 Chevy Tahoe LT 5.3 2 wheel drive. Having trouble finding the correct transmission output shaft seal/bearing. I’ve searched online but keep coming across ones that are different looking and want to be sure I get the correct one preferably OEM. If someone could point me in the right direction that would be great.

I am a bit confused by the last link. It looks totally different. Still am not quite understanding what I need specifically.

There are two styles - one for RWD and the other for 4x4. Don't put a 4x4 on a RWD or it might sound like this:

Ok so which one do you I need because the ones I am finding are not saying they are specific to 4X4 or RWD.

Post the last 8 digits of your VIN and hopefully @915_Tahoe can help out or maybe @NickTransmissions can help out too.

IIRC, you will need special tools to remove bushing and another one to install it.

Refer to post #2 by @OR VietVet - he lays it all out for you. The first two links are for the OEM first design components while the third link is for the 2nd design which is sold at most places today.
