This particular computer does a lot more than I think some of you are realizing, its not just ABS, its the entire TCS and VDC system, including my steering angle, slip sensors, speed sensors, etc.

I did actually experience what the tech at applewood was talking about at one point, southbound getting onto the queensborough on that hard right hander, I got on the skinny pedal a little and I'm not sure what happened, I initially thought the car slipped a little, and because the car couldn't tell what was going on the TCS kicked in, except it failed and literally just locked one wheel and eventually just locked all the wheels in its weird stutter step. The car didn't stop stuttering my brakes and cutting power until I came to a halt, and restarted the car. This was on my way to MDA to try and get this sorted.

At the time I was confused as to what the car was doing, I still dont really understand, but needless to say its not just as simple as the systems just not being active like the ABS is, although that is a safety system, and if I were to get into an accident, or pulled over it would be a VI in itself.

As for people hypothesizing the reasons, the speed sensors plug directly into the computer that has failed. I'm thinking they did something stupid during that process, this is based on the fact they had trouble getting the sensors working again. Also someone mentioned double checking the sensors, I haven't physically, but a friend of mine did hook it up to his modus, and we drove around, all 4 sensors are properly reading continuously.

For the people talking about the cost and that stuff, only reason I added that is so people see, I didn't take the car to a "cheap" shop, and I certainly didn't handcuff MDA on the available time with the vehicle to do the job properly and make sure everything works. And I certainly didn't handcuff him with some hard quote that was too cheap for him to make money. Like I said initially I didn't get a quote, and when I received the $2000 bill I paid it, if that was the end of it I wouldn't have questioned it at all, the only reason this thread exists is that I paid $2k and still got my car back in arguably worse condition than it went into his shop with.

Finally the reasons I dont take my car to the dealer for servicing. To be honest, most everything done on the car is by myself at this point. I did the rear wheel bearings a year prior to trying the fronts. The only reason the car went to a shop this time, is because I physically couldn't get them out in my driveway on jackstands, I needed a lift and likely a puller. As to the choice of MDA vs elsewhere, it is because the car is so modified. A lot of dealers or shops dont understand the air system, or other modifications to the car, which means even just leaving it in their care, if they need to move the car around I risk them forgetting to air it up or whatever and causing damage. I also have received comments from a couple dealers in the past due to the engine bay being totally polished that they dont really want to work on the car, this is because even something simple like spilled oil could become a problem. For these reasons I tend to be more comfortable when shops have more experience with other modified vehicles, cause they understand some of the idiosyncrasies.

There was a CV boot in the box in the backseat of the car, unrelated to the repair at hand. Just a coincidence. They did buy the new axle and install. Far as I know nothing wrong there.

Spoiler!
