May 22, 2023 With the Tacoma living in Las Vegas now, it's harder to perform various maintenance tasks as they pop up and between trips. As such, with a few general maintenance issues - oil changes, tire rotations, etc. - and a few items in recent Rig Reviews needing attention, I drove the truck home from the Three Days of R&R trip for a little TLC (Tacoma Loving Care).

So let's get started. Gathering the parts and tools Replacing the upper control arms (UCAs) is a relatively straight forward process, and nearly all the parts you'll need are included from SPC when…
