rear drive shaft question

[jimmyjimwas]

Hi my friend had his rear Drive Shaft pulled out of the rear of the transmission. He has a m1008
We were putting it back together and something didnt look right, so i checked mine and there is a rubber boot or something
sticking out of the housing where the shaft goes through
can some one help me to tell me what its called and can you buy
what im missing, Tried looking in the parts manual for the m1008 and couldnt find the part.
Also can i fix it myself
What i see when i was putting the shaft back in was a rubber washer that hugged the shaft thats it
thanks

It sounds like the rear output shaft seal on the transfer case. You can buy that in any auto parts store for about $10 or $12. That seal can be easily replaced with a large socket or piece of wood, and a hammer. Please use care so as not to destroy it because you can deform it by hitting it too hard or forcing it when it is not lined up. It is a press fit and will resist, but it is designed to go in. It seems odd to me that the seal is missing. How did the rear axle pull out of the transmission? Do you mean the driveshaft yoke pulled out of the transfer case? Before installing the new seal, make sure the old one is still not lodged in the transfer case housing and just the rubber seal part is missing. The new one will never fit if any of the old one is still present. Good luck and make sure to check for any other damage as it sounds like your friend's truck may have experienced some catastrophe.

Page 194 of the -34p Diagram number 2. Part number 9449-K. Crosses to a Timken 9449 or SKF 18992. Since the seal was missing for some time, you should consider replacing the output shaft bushing #3 at the same time. If you check online sources like RockAuto, you will notice that the seal and bushing are sold as a kit for a few pennies more than just the seal.

Before you undertake the repair. Please spend some quality time with the tech manuals. They are your friend!

Also, you said axle out of the transmission. If I am translating your description into industry standard jargon, I am assuming you are describing the rear seal on the transfer case (which is bolted to the back of the transmission) where the drive shaft slip yoke fits. All of my advice is based on this assumption. Pictures often help with diagnosing issues.

Please let us know if this helps.

Best regards ...

I am seeing a very old seal in there under all that crud. I also see a very rusty slip yoke. A rusty slip yoke shaft can chew up a new seal quickly.

The seal is available in most auto places. I provided 2 common cross references.

Given the level of experience you don't seem to have with vehicle repairs and the level of damage you indicate may have occurred, I recommend having the truck towed to a reputable suspension shop. The type of damage you are describing is not something for a beginner to tackle. Sounds like there are likely very serious safety concerns.

Also, if you could post in complete sentences and use capitalization and punctuation it would assist in comprehending what you are trying to communicate.

The pics helped. Thanks for posting them.

Wish I was a little closer to Pittsburgh to help you out a bit better.

Best regards ...

I agree with scottladdy. The old seal is still in place and in need of replacement. I also agree that the vehicle should be repaired by a qualified technician. There may be damage not readily noticeable to a novice, and there is no room for error with damaged suspension components. Your life and the life of others around you literally ride on those parts. Take care.
