Hello,

I got in a wreck about three weeks ago and have a few questions of curiosity/exploration now that I got my vehicle back.  I suffered a collision (t-bone) of my passenger side front wheel and door.  This was repaired pretty easily.  In the process it was found that my ball joints were rusted and I was missing boots.  So plenty of work done on front end.  ust before the accident i was checking on an engine light matter that first said it was an o2 sensor.  It seems an o2 sensor will affect HPG and when the check engine light on the cruise is disabled.  I had my auto body guy look at it and he said there are too many o2 sensor to pinpoint with his time and my estimate.  Is there any way to pinpoint which o2 senosr is malfunctioning? My initial search showed the part as 200 itself? (autozone quote)  Can these be found for less?

 

Then this just happened on my way to work after picking vehcile up from body shop this morning.  I noticed  a loudish grinding noise coming from the right rear ( sounds kind of like a card board on bike spokes.)  It sounds almost like a an exhaust issue but I am not sure (new muffler in august).  The sound increases in speed and volume as the the car accelerates.  I wonder if this might be a wheel bearing issue or if it will just go away. The sound really came out of nowhere.  I had this repaired about two years ago.  Do these go out so quickly and what is a general estimate for something like that?  I just put 760 into the car and am not keen on taking it in again.  How big of a problem might a bearing issue be?

 

I know there is usually a lot of great advice coming from this forum.

 

THANKS.
