What type of fluid do I put in a quadra trac transfer case?

I just got a jeep j10 and was wondering, and if in has hubs can i use something different, also how much do I put in|||chipmaker is wrong on this. You have to get quadratrac fluid. Gear oil is not correct. BJ's off road is your source for all things quadratrac. http://www.bjsoffroad.com/. You can get a new chain and all the seals from him too, which if the chain has never been replaced it needs to be. Don't let the quadratrac haters convince you to ditch it. If it's taken care of it's fine for snow or soft wheeling. Fill it to the top of the fill plug. If your chain needs replaced contact me and I'll run you through the job. |||On the back of the transfer case is two large plugs--the bottom one is a drain plug and the top one is a fill plug. Remove the top plug and fill with 80w90 or 80w120 gear lube until it runs back out of the hole and put the plug back in. Completely empty it shouldn't take more than 3-3 1/2 quarts.|||they have transfer case fluid by jeep amc/
