208 tail shaft housing?

[justhorsinaround]

What all is involved with removing the tail shaft housing on my 208? Leaks fluid at the mating surface and the P.O. tried sealing from the outside.

Didn't work.

Any thoughts?

Thanks in advance.

It just unbolts from the rest of the case. All that's really in there is the speedo gears and the oil "pump" on the output shaft. While you have it off, replace the rear output seal. And I'd recommend using "The Right Stuff" gasket maker to seal the tail housing back to the rest of the case. Pretty simple and can be done on the truck.

Well , I would of sealed it if I knew it leaked . No one mentioned to me it leaked when we towed it home

But as Scrappy said will work . Jay and I did the 27 spline one and it doesn't leak there .

AND FYI , even with a new rear seal and a new slip yoke , ATF can and will spray the underside of the truck , very little and you won't even see a drip , just some oil on the body . NP208 idiotphyschocrazy

Make sure you replace the bushing located just inside the tailshaft. Guy at the dealer parts counter told me this is the #1 reason for these leaking at the driveshaft.

GM # for the bushing is 3978765

also goto the dealer and buy a tube of their anaerobic sealant. Nothing beats it.

GM part # 1052942 "Gasket Maker"

it cures without air, and does a hell of lot better job than RTV. This is what is recommended by the dealer to use.

I replaced those along with the seals and bearings in mine and haven't had any leaks since.
