Installing Adjustable Rear Camber Arms On My Model X

Описание: Recently, I finished installing Unplugged Performance rear adjustable camber links on my MX, and it ended up as a multi-day effort with more work involved than I anticipated from the “instructions” available. I put them in to change the Tesla “hard-wired” negative camber on the rear tires that leads to extra inner tire edge wear.

I thought I’d document what happened so that others interested in doing the same job can be spared a lot of struggle I went thru to get this job completed.



The instructions from the Fix Your Tesla Model X website were deceptively simple for the link removal and installation. Link here:

I bought the Unplugged Performance camber links based on a recommendation from a Tesla Roadster mechanic. They are pretty robust, and their adjustment mechanism is simpler than other links I’ve seen. However, tech support from Unplugged Performance is minimal - they have no phone number for tech support, only a message form to which they can take a day or more to respond. The links came with no instructions, and somewhere on their website they apparently have some incomplete instructions on installation. I ended up having to re-install the links because I put the links in reversed from what they’re supposed to be. The adjustor goes on the outside (toward the wheel hub), not to the inside (away from the wheel hub). So, I got to do the installation twice, but fortunately before setting the final inner bolt torque effort. However, the video still shows what it takes to install these links - just put them in the correct orientation!

Torquing the inner mounting bolt turned out to be considerably more work than I expected, and I didn’t record that on video. The bolt torque has to be set from beneath the vehicle, and it requires making a special 18 mm socket. I cut down a deep ½” drive socket by about ⅝” with an angle grinder to enable fitting both the socket and the end of the torque wrench into the tight space around the nut on the left side suspension. There is no way to get a torque wrench & socket on the left side bolt head. The same cut-down socket & torque wrench fits on the right side bolt head.

Step #9 is for the inside camber link bolt. The instructions make it look too easy.

To get enough swing on the torque wrench to tighten the bolt, the rear undercover has to be removed. There is a slot in the undercover next to the suspension components that allows one to get the wrench on the bolt/nut, but not enough room to swing the wrench. One could cut out some of the undercover for extra room or remove it. I naively chose to remove the undercover.

Taking the undercover off is quite a chore with the rear of the vehicle on jack stands. The worst part is either getting the front edge of the undercover disengaged from the vehicle or putting it back on. I had to raise the vehicle higher with 2x4’s to get just a little extra room to reconnect the undercover front edge to the frame. It has to be done with the undercover angled downward to clear a frame ridge.
