Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
The first thing you should do is see if any trouble codes are setting in the OBDII system. This will give us an idea which sensor is acting up. That way we will be able to tell if the aftermarket hubs are to blame or if it's a bad sensor.
Hello my name is ***** ***** thank you for your question.
When you replace the Wheel bearing or Hub assemblies the abs sensor has to be removed other wise you will break the sensor. So if you did not have a ABS light on before the bearing was done and do now, the sensor was most likely broken cause they did not remove it when they did the bearing which would make them responsible for the breaking of the sensor.
Do you have any more questions on this?
If they removed it, make sure you have the proper hub. If it doesn't have the magnetic pickup for the sensor to read properly, then the hub would need to be changed to the proper hub
Somehow Jay jumped in on my answer. I'm sorry if it looks confusing- that typically doesn't happen.
Do you know the part number for the replacement hubs that you used?
I found that number available in TIMKEN. It appears to be correct and there aren't multiple model options (such as one without ABS, one with).
I think your best bet is to get a hold of a scan tool and see if you can get it to display a readout on the speed sensors. That way you will be able to tell if one or more isn't working.
One would assume the speed sensor would work with it especially since the tone ring (the part that generates the signal for the speed sensor to pick up) isn't part of the hub on this model. The tone ring is on the axle shaft.
According to the Timken site the tone ring wasn't part of the hub- maybe what they meant was it wasn't compatible with speed sensors on this model. Some Timken stuff is really good, others just don't work. I'm glad you got it sorted out.
Please let me know if you need help in the future.
