Have rear differential lube checked and oil pressure tested with a test gauge. Mechanic can advise corrective action after testing.

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
