All FATAL.
I would like to preface this by saying, I myself, did not know Mazda/Ford used these "press in collars". Also the previous suspension parts did not have a washer to reuse, they had flare nuts that I didn't think to reuse because the new parts had new fasteners.
This last weekend I replaced the entire front suspension on my girlfriends 2003 Mazda 6 with Moog parts, as I have used them in the past and they have been great.
However, Moog has a potentially fatal part on the shelves that I want to see removed from sale.
In 2003 Mazda 6's the spindle is made of cast iron and the lower ball joints have a forged, press in collar to add strength to the lower ball joints, that the lower ball joints then slide through.
Moog provided a Nylock nut, not a flare nut, and NO washer.
So the provided nylock's diameter was not wider than the press in collar allowing the ball joint to and press in collar assembly to pop out from the spindle.
There are 4 lower control arm ball joints on this car (2 a side), all able to be popped out by normal driving.
One popped out while we were driving 50mph and it caused us to veer towards the oncoming lane, luckily there were no oncoming vehicles. Once the vehicle was slowed to almost a stop we could steer the car to the edge. The control arm was poking through the spokes of the wheel.
I fixed the issue by using the old flare nuts from the old suspension parts.
I was so upset that I wanted to sue Moog, but I can't prove that I didn't tamper with anything and I already put the car back together to get it home.
However, if Moog took the time to re-assess the part on the shelf, I'm positive their engineers would see the part is fatal. Moog should ship these control arms with FLARE NUTS and not a small diameter nylock.
