Learn how to swap a damaged or worn 4-prong wireless charging mount head to restore hands-free charging in your vehicle. Step-by-step guide with common mistakes to avoid.

Quick answer

Replacing a 4-prong wireless charging mount head is a straightforward fix that restores charging without buying a whole new mount. The key is verifying prong style compatibility before you start.

Why replace just the head instead of the whole mount?

The charging mount head is the part that wears out or gets damaged over time, especially if you frequently remove your phone. Swapping only the head saves money and keeps your existing mount arm or base in use. The ToughTested 4-Prong Wireless Charging Mount Head Replacement is designed as a spare part for compatible 4-prong setups, so you don't need to replace the entire kit.

What you'll need before starting

You'll need the replacement mount head, a small Phillips-head screwdriver, and about 10 minutes. Check that your existing mount uses a 4-prong connector style — the replacement head is not universal and only fits select ToughTested mount kits. If the prong shape or spacing looks different, stop and verify compatibility to avoid damaging the mount arm.

Step-by-step replacement process

Step 1: Remove the old mount head: Unplug any power cable from the mount. Locate the small screw or locking mechanism securing the head to the mount arm. Use a Phillips-head screwdriver to remove the screw, then slide the old head off the arm. Keep the screw in a safe place. Common mistake: Forgetting to unplug power first — always disconnect to avoid shorting the charging coil.
Step 2: Verify prong alignment: Hold the replacement head next to the mount arm connector. Check that the prong pattern and spacing match exactly. The 4-prong design is specific to certain ToughTested models; if the alignment is off, do not force it. Common mistake: Assuming all 4-prong heads are identical — prong shape and spacing vary between mount generations.
Step 3: Attach the new head: Slide the replacement head onto the mount arm until it seats fully. Align the screw hole and reinsert the screw. Tighten it snugly — do not overtighten, as the plastic housing can crack. Common mistake: Overtightening the screw can strip the threads or crack the mount head housing.
Step 4: Test wireless charging: Reconnect power to the mount. Place your phone on the charging pad and confirm the charging indicator lights up. If it doesn't, check that the head is fully seated and the power cable is secure. Common mistake: Skipping the test step — a loose connection can cause intermittent charging that's hard to diagnose later.
