    Auto ride build differences (and my dumb mistake)

    Each side on the front has a height sensor with a two-wire connector. Disconnect this and wire up each of the resistor terminals to one of the connector wires, then zip-tie it to something so it doesn't flop around. Some people cut the connector off to get to the wires, others get more...

    Humming noise when phone is charging and plugged into the aux

    I have an aux port wired up to the factory radio in my 2005 suburban using the XM receiver hack. The Bluetooth adapter I plug into it has a ground loop isolator built into it. Maybe that’s what you need? Something like this...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    One last post to complete this thread as far as my EBCM questions go. According to one of the ebay module repair services my Suburban has a Kelsey Hayes Series 30 EBCM that's not repairable. Hope it doesn't go out because it doesn't appear to be for sale anywhere. Modulemaster's has these...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    I've removed the air compressor from behind the left rear tire and the sound was still there. Next I removed the electrical connector from the EBCM and the sound is still there, so I guess it's not my ABS pump running. It was a single connector, and not two different connectors like the...

    Autoride or Bilstein 5100 shocks?

    I bet when new the Autoride would be more compliant than 5100's, but most with Autoride have enough miles on their vehicles that the systems are in need of lots of work. I bought my Suburban in March and it had 157k miles on it. Maybe the electronics in the front shocks were still working...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    I replaced the fuel pump a little over a month and maybe a 1000 miles ago, but the noise has been there since I bought the truck in March. It could be making the noise but I don't think that's it. I think I'm just going to take a chance and pull off the EBCM if I can get the torx screws out...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    i paid closer attention to when the pump noise starts and it is right around 40mph. I can stick it up on the stands, sit in the driver's seat and run it to that speed and listen for the noise. If it's there I'll get my wife to do the same and I'll listen from the ground, but don't think I'll...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    Maybe take a chance with my cell phone, dunno. I used to listen to Pat "Motorweek" Goss' radio show and he talked about a tool he used called a "chassis ear" to figure out where sounds came from. It had multiple microphones and I think to pinpoint it I may need one in the front by the ABS pump...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    I could try to duplicate it that way if I could convince myself it's safe. I have plenty of jack stands. I'll only have myself to blame if it falls on me! I also should just get rid of the Autoride compressor since it's not needed, and eliminate that as a possibility. I've left it connected...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    The sound does not go up and down in sync with speed; it really sounds like a pump running, and it can run at two different speeds. It isn't running when the truck is stopped. I've inspected everything underneath real well recently since I had to replace the fuel pump and dropped the tank, and...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    No vibrations. Truck drives smooth and straight up to the fastest I've had it, about 75-80mph. The noise does not speed up or slow down with the truck's speed, its either the fast speed or switches to the slower ticka-ticka speed as I come to a stop. Sometimes while driving the fast speed...

    2005 Suburban ABS pump seems to run while driving, not when stopped

    I've got a 2005 Suburban (160,000+ miles) and I'm hearing a running pump noise that I think is the ABS pump, but I'm not sure? I have a Service Stability message in the DIC that comes on when I put the truck in drive and hit about 5mph. The noise is present whether the ABS fuse is pulled or...
