Looking at a 02 tomorrow. Common problems?

I am looking at the short version of a 02 Escalade tomorrow. I used the search function and did not come up with anything other than certain problems people had. I am not new to forums and will be around here for a long time if all goes well tomorrow. He says the transfercase leaks and he stopped using it and hasnt moved since. Is there a rebuild kit or can I swap one in from any tahoe or yukon? What does a used one go for if its trashed and I need to replace it. More importantly what are the common issues to look for when I go look. My buddy has one of the EXT ones and he likes it. I am worried about the air ride if it goes out, how expensive of a fix is this for the air bags and compressor? Any aftermarket companies that make good parts for a fraction of the cost? Also wondering if the air ride does go out in the back and its extremely expensive to fix, can't you just use shocks that would fit the tahoe and yukon? Obviously the sensors would be on but is there a bypass?
Thanks guys, hope to be here for a while!

The transfer case is a Cadillac only setup as It is a single speed full time unit you may be able to find a used one at a junk yard(if you can't get the seal replaced)

I suggest driving it to make sure that the engine and transmission is in good shape

The front axle is a common issue with these vehicles along with the shocks and compressor

As far as getting aftermarket parts for the suspsion system can be got on the arnott website(they are a sponsor and vendor on here) they sale both rebuilt oem shocks and compressor replacements along with passive gas shocks

Another suggestion is check and change the fluids(if needed)
Drivetrain should crossover with the gmc denali it has the same setup

I know some has the controls on the dash and some don't the rpo codes is the best way to be sure but I haven't seen a gmc Denali in person but the service manuals I have mention the yukon for the transfer case so they must use the same model(I always thought the gmc yukons shared the hummer h2s transfer case I guess I was in error)
Yeah the denali's are the only ones along with certain escalades with no transfer case controls which makes the difference between awd and 4wd.... The regular yukons long or short and the suburbans and tahoes may share the same t-case as the hummer because they are 4wd but as well i am not positive
