2000 Leaks

Transfer case leaks, and windshield washer container leaks, any ideas and est on cost to repair. I did see one thread on the washer container leak indicating it was related to battery acid. Any more input from anyone would be helpful.
Thanks

I have a 03 and the front axel seal was leaking drivers side. $180 bucks at the stealer.

I am currently working on a 2004 yukon with a transfer case leak. The fluid on the ground is blue but not windsheid washer fluid. Its autotrak II fluid. The transfer case has small pin holes developing in it. Aside from replacing it, the only answer i had was to jb weld it. The case is magnizium or something like that and Im told cannot be welded. Maybe this will help you figure out your problem.
