How hard is it to replace the gasket between the two halfs of the transfer case. Now that the weather is warming up I figure it's time to get rid of a couple more leaks. The t-case looks like it is leaking between the two main cases. The gasket is squished out from between the bottom of them. It looks like I could do it right on the truck - remove the rear driveshaft and split the cases.

Does this sound right? Is there anything in there that is under pressure or spring loaded or anything? Any hints or tips? I have had all kind of things apart in the past but NEVER a transfer case.

Is the gasket a dealer item? Anything else I should inspect or replace once I open it up? Anything I need to measure, check or adjust?

Thanks All !!

 

They use RTV from the factory. Grab some RTV, I would take the t case out. It's probably less than an hour and it's on the bench. There is a spring in there, don't worry it won't pop out, but be aware of its presence. When you split the two halves, just make sure and put the oil pickup back in and the rest is cake. I put mine together with no problems. Actually you might as well order up a set of shift fork pads. It's only about $15, and it's worth it as long as you're in there. I did mine all by myself, and I've never been inside one before. Have fun!!!

BTW, take a look in my gallery to see the inside of the case. it's not too complicated. Everything inside is pretty self explanitory.

 

Crimedog,

Thanks for the reply! The pictures in your gallery help! I like the one with the wheel cylinder comparison (my next task). Is there an oil pump in there? I guess there must be or it wouldn't need a pickup.


So it's as easy as remove, clean, install shift fork pads, RTV and install?

Thanks!

 

You got it Sidewinder. The pump is the little "disk type thing" that's visible when you take the speedo housing off. If I were you, I'd take all the housing pieces apart, start with the tailhousing (that the driveshaft goes into), there should be a snap ring or bearing there, then take the speedo housing off, take the bearing and/or speedo gear off, then you're ready o split the two halves. To be honest, it is also a good idea to replace the input seal and front and rear output seals. Their only about $35 for the set.

 

Getting to that snap ring on the tailshaft housing proved to be futile for me without a 90* pair of pliers.. I had to drop the case.
