Notes:
Non-Knurled ball joints recommended for replacing non-knurled ball jointsDue to these ball joints being tight tolerance, metal on metal ball joints, proper fitment is critical. Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press fit, knurled ball joints are required.
Use of the improper ball joint style for the axle housing voids our lifetime warranty. It is up to the installer to verify the proper ball joint style is being used.

Great mount / Terrible charge rate
Love the mount. Easy to install and with a small piece of double sided tape under the top edge, it’s very secure…
The magnetic mount is strong enough to hold an iPhone max (at least mine).
The charging ability is where it falls short *BAD! It will charge but, barely..
If you’re using maps, making calls, etc.. the phone continues to drain at an alarming rate…

Not suitable if you have a silicone case.
I'm waiting for delivery of new phone case, as the silicone one I have on my phone will not hold onto the magnet provided for this holder. Installation was a snap and I love how it looks in my car. Cost seems fair for the product. Fingers crossed that it will work fine once I get a new case.

Charger portion stopped working twice now
Works well until it doesn't. Was excited to get the phone mount off the car vent but I have gone through one replacement already and now I'm past the point to completely return it. Twice now the charging portion has failed. The first one stopped lighting up completely with in about a week and now this one just constantly flashes and no longer charges after another few weeks. I have tried different cords and outlets in my car with no success. The magnet portion however is strong and does hold the phone well.

Perfect for every day use
The Wincar Magnetic Wireless Phone Mount and Charger is a thoughtfully designed accessory tailored for Toyota 4Runner models from 2010 to the present, and it also fits well with other vehicles using a 17mm ball mount base. The package includes a sturdy mount, a 15W magnetic wireless charger, a charging cable, and two steel rings. These steel rings are particularly useful for those who do not own a MagSafe-compatible phone or case, ensuring broader compatibility.
I specifically purchased this charger and holder to use with my existing 17mm ball mount base, which I found challenging to match with most other products—especially for my Lexus GX460. While there are many phone holders on the market, very few offer the dual functionality of both MagSafe mounting and wireless charging in one unit. This all-in-one solution eliminates the need for multiple accessories, but it’s important to note that the charger /mount
require a power connection to operate.
In terms of performance, the Wincar mount and charger deliver impressively. When connected to a reliable USB-C charging source or a USB-C cigarette lighter adapter, the magnetic grip is strong, keeping the phone securely in place even during bumpy rides. The wireless charging is efficient, providing a reasonably fast charge without overheating or lag. The magnetic force is particularly robust, ensuring that the phone remains stable and aligned for optimal charging.
Overall, this mount and charger combination offers a seamless, convenient experience for anyone seeking a reliable phone holder and charger for their vehicle. For my needs, it has proven to be both practical and effective.
