I am leaking fluid/oil from both sides of the driveshaft. The side of the transfer case and the axle side. I know the rear pinion is the name of one side but I don't know what the name is of the seal on the transfer case side(sorry). Anyways I don't think I know enough to mess with it myself and so I was wondering what a fair price and time would be if I gave it to a shop? I live in southern california so there is a million different mechanics and shops around so I need to know a fair price when dealing with them. Thanks

It is called exactly what it appears to be.............(You got it right)
Transfer Case Output Seal..........


It is not really that complicated to replace, but it involves removing the driveshaft, the boot (it's clamped on), and the slinger (you need a puller) to get to the seal..................


The pinion seal is a little more complicated, as it involves removing the pinion yoke, and once the seal is removed, you have to remove the outer pinion bearing and crush-sleeve, and replace with a new crush-sleeve to set proper pinion preload upon reinstallation of the yoke...........

so if it's clamped on how do I get it unclamped? I might just try the transfer case side myself it they ask for ridiculous prices for the transfer case side. The pinion seal...sounds a bit out of my skill range and too time consuming right now. Thanks for the info and help.

The boot is usually installed with "Pinch" type clamps (like the kind that are on CV axles on a front wheel drive car)
They have to be pried apart, and mostly broken to get them off.........

When you reinstall the boot, you can either get new pinch clamps, and use a crimping tool to tighten them, or I have seen some people use regular worm screw type clamps to put the boot back on.........
