TL;DR - I am not happy with the lifespan I got out of the X-Axis joints on my SPC upper control arms (UCAs), so I'm going back to the original polyurethane bushing-based SPC UCAs.

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). On my list for a warm spring day were the following tasks: Routine maintenance - Change the oil, Rotate the tires Grease drive train. Check the new SPC UCAs for play in…

Older SPC UCAs with SpecRide bushings vs. newer arms with the X-Axis joint.
TL;DR - I no longer recommend SPC upper control arms (UCAs) if they contain X-Axis bushings.

September 1, 2022. Note: There is an important update below. It was more than three years and 120K miles ago that I installed SPC UCAs on the Tacoma. Shortly after installation, SPC came out with an improved design that was a single forged piece of material, with an entirely new type of joint. That joint - which they call the "X-Axis" joint - was essentially a sealed spherical bearing that replaces the polyurethane bushings where the UCA is mounted to the frame. And so, when I took the truck in for an alignment and the alignment tech (a good one,…

My original SPC UCAs with sleeved poly bushings on the left; new UCAs with the X-Axis joint on the right.
TL;DR - the last time I got an alignment, the tech mentioned that the rear passenger side bushing on the upper control arm (UCA) was starting to get a bit loose. After some consideration, I decided to install completely new UCAs, with lifetime joints so I never have to worry about those bushings again.

Time for more new bushings.
TL;DR - Replacing my LCA bushings didn't resolve my squeaks. Time to start thinking about UCAs and rear leaf spring bushings.

I recently installed SPC Performance upper control arms (25460) on my 2000 Tacoma, and it went great. In addition to the story of the install, I figured a detailed set of instructions for anyone wanting to tackle this themselves would be nice to put together, since it's hard to find that written down in one concise place with a list of everything you need to do the job. 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…

January 15, 2019. What can I say? It's the end of an era, sort of. Really, it's the end of a transition period for the Tacoma - a time when it was transitioning from daily driver and home renovation hauler to a more dedicated exploration vehicle. It was nearly three years ago that this transition started, one of my first modifications being a new Toytec BOSS lift in order to support the Relentless armor I was soon to install. Over the last three years, that @Toytec Lifts setup has done everything I could have asked of it. No, that's not right…

Not only functional, but they look good too!
TL;DR - the ADS setup is working great. We didn't do much dirt travel this time, but what little we did do was no problem at all. More to come in the future.
