It appears there was not enough spacer on there had driver of my 2014 MBP when upgrading to Mohave. I want to erase my har drive and re install the OS. But, when I go into the disk utility in “recovery mode” the hard driver does not appear. Is there a way to wipe the disk in this situation? Thanks in advance.

"regular" Recovery mode (command-R) loads from the Recovery HD partition on the drive. Since that partition is in use, you cannot erase the entire drive. You need somewhere else to stand.
Internet Recovery (option-Command-R) starts from code in the Mac's ROM, and downloads the things it needs from the Internet, and stores them in as many as 18 RAM disks, to avoid using the drive at all. You CAN select the drive (by hardware-name) and erase it all from Internet Recovery. At this writing, be sure to choose GUID partition Map and HFS+ Extended Volume. Installer in not ready for an empty drive in APFS just yet.
