What gear oil is used in the rear end? Does it have to be synthetic?
Hello mcgyver1467-- The gear oil that would fit either of the differentials available on the 1999 Chevrolet Silverado is indeed synthetic, with a weight of 75w90. For information about non-synthetic oils, I would need more information about your truck. Good luck from Bovan.
