Just bought a 2003 Rubicon.
When i test drove it on a trail, had no problem in 4WD-Low. Lockers worked.
I never tried it in 4WD-High, until today. When i shift in to 4WD-H, nothing engages. Its like being in neutral, regardless of the gear (only tried it in 1,2&3). When i move it to 4WD-Low, everything seems to work fine.
In process of changing fluids, thats why i had it out and tried to put it into 4WD (trying to heat up transfer case and tranny) Transfer case was EXTREMELY low.
any help is appreciated.
