Tesla Model S Front Upper Control Arm Ball Joint Replacement (2021 – 2026+)

No. If you do not own the Unplugged Performance FUCA, Ultimate Edition, this replacement joint has nothing to bolt into. Start with the front upper control arm set, which brings adjustable camber, caster, and toe and comes with the pill already installed. Buy this part later, once your joints have logged real miles and need refreshing.

Because the FUCA uses a flip pill, keeping a spare replacement joint lets you switch between a street alignment and a track alignment in minutes rather than booking an alignment each time. Racers who move between road camber and slick camber often keep an extra on hand for exactly this. For most street owners it stays a wear-replacement part, not something you touch often.

Watch for new play, clunking, or looseness in the front end, or a ball joint that no longer holds its setting cleanly. Hard use accelerates it: repeated high-speed, high-grip cornering on street or track wears the joint faster than gentle commuting. Since it is sold per side, you can replace one or both depending on what your inspection shows. When in doubt, our team can help you diagnose it.

The $180.00 is per side. If you are refreshing both front corners, you order two. Selling it individually keeps the cost down when only one joint has worn, which is common when one side has taken more abuse from a particular road or track direction. The part ships the next business day, so a track weekend rarely has to wait on it.

If you are comfortable working on the FUCA, the joint swap is a manageable job at home with basic tools, and the flip-pill design is meant for quick changes. Set your camber afterward, since disturbing the joint changes alignment. Owners in the Los Angeles area can have our Hawthorne shop handle it and confirm the setting on the rack. Keep the retainer hardware clean and torqued to spec.
