On the center bolt, I turned the wheel all the way to the left and used a 6" extension to clear the boot.

I drove the car on the highway for the first time today and the service stability system light came on as did the traction control light. I pulled off to get gas and everything returned to normal on its own but came on later in the day.
I admit I forgot to use the dielectric grease on the WSS connector so I checked to be sure the connector was seated and packed it with grease. Hopefully, that'* all it is.

Unfortunately, the same thing happened today despite having packed the connector and being double sure it was tight. As happened yesterday, the problem disappeared when I cycled power. We'll see what happens on the way home tonight but I'm not confident that the problem will just disappear.
Any ideas? I'd hate to think that the problem is the new bearing assembly itself because how would you prove it was defective except by putting the old one back in?

Ågreed although the fact that it had never happened before until I changed the assembly out(I only have done the one for now) would certainly lead me to think it was that one.
It happened again on the way home tonight and I figured out what the common denominator is. On my way to work, I pass under transmission lines carrying 745,000 volts and each of the 4 times it has done this was when I passed under these lines. Keep in mind I have passed under these lines over 1000 times and never had a problem before but now the system has gone offline each of the 4 times I have passed under them. This would lead me to believe it has something to do with the shielding that is supposed to keep stray signals out of the stability system. I'll try comparing the old and new assemblies to see if something stands out in the way of a difference.
