First time posting. I have a 2019 Silverado 4x4 with the 5.3 V-8. My free oil changes from the dealer are all gone so I am changing my own oil now. I cannot find a single grease zerk under the front end anywhere. I know my eyes aren't what they used to be, but I was just curious to know if I am really blind or are there not any? Thanks in advance for any help!
