2005 Cadillac Escalade Question: Escalde 2005 has the following problems

Rear end makes a whining noise when the car is in motion. The faster the car goes the louder the noise. and the low pressure warning comes on when the car is idling -
Answer 1
Have rear differential lube checked and oil pressure tested with a test gauge. Mechanic can advise corrective action after testing. -
Answer 2
Check the rear end gear oil level or condition of the gear oil for possible drain and refill, possible wheel bearing issue. The low pressure I assume from previous post is the oil pressure. Have the oil pressure tested with a pressure gauge, more then likely a oil pressure sender. we're on the same page this time PR, Lol -
