Will set off the ABsINOP light? I have them on the rear. The light is on you think this is what i causing it? havent had a chance to take the spacers off to see.

 

I highly doubt a wheel spacer will cause an ABS INOP light since it has no impact on the rolling diameter of the tire. I've been running spacers on the rear for years with no issue. More than likely you have a sensor or connector problem.

 

No. The major affect to the ABS light would be if the front and rear wheels are a major difference in oeverall diameter.

 

where would I check the connections at and everything to make sure it didnt come unplugged?
