Expedition Transfer Case Question

Hello,

I have a 1998 Expy 4x4 5.4L and wanted to confirm if my suv has 2 transfer cases?
Also, is it a good idea to change the transfer case oil if I'm changing the transmission oil and filter? What type of oil should I use for both, Mercon V?

Thank you

You only have one transfer case. Yes, do both at the same time since the t-case doesn't take long or much fluid. My tranny & t-case require mercon. Look at your tranny dipstick for fluid spec.

Make sure the top or fill plug is loosened before draining the transfer case. Just to make sure you can fill it back up.

2 qts fro transfer case, so might as well use synthetic. I bought 'OEM' brand hand pump from Autozone that screws in to Mobil1 1-qt plastic bottle, made the job easier.

I replace the t-case oil every 10k to get rid of annoying whine under the truck.
