Totally separate. units. There is a fill and drain plug on the back of the transfer case.

 

Damn I feel stupid now my dad who is a mechanic told me they were one unit idk if he was trying to deter me from putting a sye on or what but how do i go about checking the fluid

 

Park on level ground, and pull the TOP plug on the transfer case (there is a fill plug, top, and drain plug, bottom) The fluid should be level with hole for the top plug.

If you've never changed it, now's probably a good time to change the fluid in the TC.

 

Who knows when it was last changed the prior owner didnt take care of the jeep very well had to replace a lotta **** on it the most disturbing thing i replaced was the radiator and thermostat housing. Radiator was stopped up with sand and t-stat housing housing was pitted from where they ran salt water through it :/

 

You need to check/change every fluid in this Jeep aSAP. You know the PO was a flake. Don't invite disaster.

 

After about 3 months of owning mine. I went out and spent about 85 bucks on fluid and a gasket. I used Royal Purple In the front diff, T-case and rear diff. It gives you piece of mind.

 

For real and Ill do it asap right now Im still fixing some things from where I rolled it on its roof a month ago but I plan on doing the t-case rear ends and engine oil asap. Maybe this will fix my issue Thank you

 

Excellent plan.
Grease the front steering components and driveshaft u-joints whil you're at it.

 

Ya front end could probly use a rebuild lol ill do the adjustable trac bar and replace my ball joints and stuff
