Tesla Model X Front Upper Control Arm Ball Joint Replacement

A ball joint is the pivoting connection that lets a control arm move with the suspension while the wheel steers and travels. It carries load constantly, so it counts as a wear item. Rough roads and repeated high-grip cornering both accelerate that wear. On the Model X FUCA Ultimate Edition, this replaceable pill/ball joint is what carries the front camber, caster, and toe adjustment, so keeping it fresh keeps your alignment honest.

It fits the Unplugged Performance Front Upper Control Arm Set, Ultimate Edition (FUCA) for the Model X. It is designed exclusively for that arm, not for the factory Model X upper control arm or for other UP suspension components. If you run the FUCA set, this is the correct service part. Anyone still on stock arms would want the full FUCA set first.

The listed $180.00 is priced per side. A Model X has a front upper control arm on each side, so a full front refresh means ordering two. We call that out on the page so there are no surprises at the alignment rack. The part carries SKU UP-MX2-102-2.1 and ships the next business day.

Because they let you swap between street and track alignment quickly. Drivers who move between a comfortable street setup and an aggressive track setup put more cycles through the joint, and having replacements on hand means a worn pill never keeps the car off the track. It is cheap insurance for a Model X that sees real lapping. High-speed, high-grip cornering is exactly the load that wears these fastest.

Yes. The ball joint sits inside the adjustable FUCA, so any time it comes out and goes back in, the front alignment shifts and needs resetting. Plan for an alignment as part of the job. Our team in Hawthorne can handle the swap and the alignment together, or any shop comfortable with Model X suspension can do it.

Three tells usually show up first: free play in the joint, a clunk over bumps, and an alignment that drifts off its numbers between visits. Any of those means the pivot has worn past its useful life. A tracked Model X should have it checked at regular service rather than waiting for symptoms. New vagueness in the front end that was not there before is your cue to inspect it.

Installing aftermarket parts does not automatically void your Tesla warranty. Under the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts), a manufacturer cannot void your warranty simply because you installed aftermarket parts. Tesla must prove that the aftermarket part caused the specific failure in question to deny a warranty claim. UP recommends retaining all factory parts to allow reverting to stock if needed.
