Warning light "R DIFF TEMP" what is this - 2006 Subaru B9 Tribeca

Bad oil pressure sensor, oil pump, balancer-shaft bearings..
Which grade of oil did you use? Did you try to check the pressure with an oil-pressure gauge?

low on rear differential lubricant. it's getting hot.

The centre diff is the vehicle's transfer case, the gearbox which switches to 4wd or all wheel drive. It is inter active with the stability system, so when on senses a fault, it'll send an error message to the other system. Have it checked by a technician who can plug in a scanner that will help pinpoint the source of the problem.

the diff lock stocked

if the shift is being made and the car is in gear it will not change ,in some cases it is necesary to reverse a few times to allow shifts to occur if this still fails you could have a sticky solonoid ,these are mounted on the r/f inner guard there are two of the next to each other make sure there is vacume at the solonoids as the car will allways fail in 4wd mode it requires vacume to allow it to disengage the front diff on start up,that is why there is a grinding noise if you switch off the motor and free wheel to a stop the front diff tries to engage

if the sensor is located on the diff. sometimes the lube in diff gets lots of metal shaving and they collect on tip of abs sensor and cause it to ground out to triger light on if this is the case you have to have diff. flushed and refilled with fresh lube.
