I have a 2001 wrangler. When towing it with my rv the front

Customer Question

I have a 2001 wrangler. When towing it with my rv the front diff overheated to the point of blowing oil out the vent. It does not do it when just driving.
JA: Have you checked the coolant? Have you checked for a leak in the cooling system?
Customer: What would that have to do with the front diff?
JA: Are you fixing your Wrangler yourself? What have you tried so far?
Customer: All I have done is remove the cover. Everything looks good. Oil just overheated. Diff was so hot I could not touch it.
JA: Anything else you want the mechanic to know before I connect you?
Customer: NO

I have driven the jeep around for hours and it does not overheat the front diff. I hooked it to the rv and only went about 20 miles and it was blowing oil out the overflow. I could not touch the diff case it was so hot.

are you leaving the transmission in park? the transmission need to be in nuetral, as well as the transfer case?

Customer: replied 8 months ago.
It is a manual transmission. The owners manual says to put the transmission in gear. I had it in 4th.
Expert:  Tim Mohr replied 8 months ago.

put in nuetral and drive it, and see if it still blows oil out the vent tube, can you do this?
