Leak from output shaft on T-case - hard to replace?
 

Took the SRX on a 5-hr trip to Indiana this weekend, and after parking noticed a few drops of oil on the driveway. Slid under the car and saw the leak was coming from the front output shaft seal on the transfer case. It's a small leak, but I'm sure the T-case doesn't hold THAT much oil so I should address it promptly. Has anybody else encountered this leak and if so, what is involved in the replacement? I assume it's not as simple as just pulling out the front input shaft, pulling the seal, hammering in a new seal, and then re-filling the oil? Is it gonna involve dropping the t-case? [:o]
