Electrical


This past weekend, I replaced the passenger side wheel hub and bearings on my car. In order to replace the bearings I had to remove the steering knuckle and take it to a machine shop, which means removing the ABS wheel speed sensor. I removed it and reinstalled exactly as it was.

Since I finished and began driving the car, I have notice/endured several electrical problems, including but not limited to:

-Power Window/Lock Failure, on all doors.
-Radio shorts out and ejects CD--coincides with depression of brake pedal.
-Power fails on entire car. No crank, no interior lights.
-Power seatbelts fail to release upon door open.
-Instrument Panel and Headlight flicker.

The brakes appear to be operating correctly, but some of the malfunctions appear to coincide with pressing the brake pedal.

All I can think of is a loose ground, check these and all electrical connection near the strut or strut tower you may have accidentily knocked loose/off.

When I rebuilt the Hub, because the hub was warn, I used a copper shim, and some epoxy between the inner hub and the bearings. It has worked in preventing the hub from wobbling, but could that cause a grounding problem?

Also, could a damages ABS speed sensor cause some sort of electrical shorting?

Maybe, but is the ABS light out now? And check the connections at the battery terminals, these corrode and give tons of headaches.
