I installed the SPC front Arm camber kit for my 06 Coupe. The insides of my tires were wearing down too fast for my comfort. So I installed the arms and set them max 'out' and took to shop with the bag of included shims in case he needed them.

Before the camber arms, my alignment was sitting at L -1.5 R -1.4

With just the SPC arms set to max positive the alignment was at L -1.2 R -0.5

So the right side was perfect, but it looked like he needed to install the shim on the left to get more adjustment. When I picked the car up, he said he was having trouble with the ABS sensor, and sure enough, driving home the ABS / SLIP / VDC OFF lights lit up. On slight breaking I could feel the ABS pulsating before the lights finally came on.

I was half way expecting this problem due to my research here on driver. So I got it home and went to play with the ABS sensor and noticed several issues:

First the rubberish surface that the ABS sensor faces has a big gouge in it.
Second, he didn't install the bracket SPC provides. Upon inspection I can see the bracket was bent, so he obviously installed it wrong and went about shimming the sensor himself.
I also noticed the plastic bracket part of the ABS sensor was cracked.

So my question is, can this part of the front wheel hub be repaired, or do I need a whole new hub? Also, does this affect the readings to the ABS sensor (it's rubber, but I still think it's why my ABS goes haywire)?

Pictures of the damage:

 

I don't know about fixing but, but I would take it back to him, show him what he did and get him to fix/pay to have it fixed.

 

Sorry to hear about your misfortune

That portion of the hub should have a plastic shield over it, but it does appear that damage would affect your ABS/VDC and to fix it you have to replace the entire hub. LINK

Let me know if I can help you with anything! Goodluck!

Thanks for the quick responses. The shop owned up to his mistake and is ordering a replacement hub.

Guess this shows how sensitive the "Tone Ring" is on the back of the hub.

 

Consider yourself lucky, hope replacing the hub resolves any issues you have with the ABS. Strange how the left side of our cars never comes in as good as the right side during alignment....mine's the same way but no excessive tire wear is visible.

Picked up replacement hub from the shop last night, I refused to allow him to even replace it. He had the missing dust cover as well as a break pad shim (spare parts after working on a car, really??).

Swapped out the hub, checked the ABS sensor alignment and gap, and poof, no more ABS lights! So glad the sensor itself wasn't busted.

Also, just an FYI, I found that driving at a steady speed around 25-30 mph for about 500 feet or so was enough to trip the ABS light. So I would keep it slow and steady until the light came on when I started driving anywhere, other wise the ABS would pulse like crazy the first few stops until it realized something was wrong.

 

My mechanic showed me a cool trick when I had this issue (but no time to fix it at the moment). Remove the brake fluid cap and push the plunger all the way down. That will instantly trigger the christmas tree and keep the ABS quiet until you clear the codes or disconnect the battery. Did that once and drove it for about a week without ABS intervention until finally correcting the sensor issue.
