Well I'm stumped. I have a 2006 GMC 3500 Duramax. It started out  having the  intermittent ABS light. It's a work truck so it doesn't get driven that much. Only saw the light once or twice. I took the flatbed off and installed a dump bed. When she was bare back I power washed the frame, axle, and such. A day or so after the power wash, and the installation of the dumper(they happened the same day) I noticed a burning plastic smell coming from the truck. The truck was not in use just sitting in the shop. Couldn't even tell it was coming from the truck yet. Next day I was working on her some more and that's when I noticed white thick smoke coming from the ABS module/pump. I instantly unplugged the Batts, then unplugged the module/pump.  So there ya have it, if I plug the mudule/pump back in instant thick stinky white smoke. This happened a good year ago. Checked the rear of the wiring harness where I was power washing. But other than that don't even know where to start? Could a bad whell speed sensor be  the culprit? Thanks for help in advance.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!!

      OCI, not when but why?

      We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research.

      Trim level custom/pro

      By newdude · Posted

      Sierra HD Pro:   - If you want a power driver's seat on the Pro, you can't get it.  You have to go to SLE.   - Factory remote start?  Can't get it on any of the Sierra Pro trim (1500 or HD).  You have to go SLE.     - 7 inch radio has limitations for replacement if you wanted to upgrade the screen, etc.    - Steering wheel radio controls?  Nope.  Can you add them?  Yes.  NOT CHEAP.  Requires a new instrument cluster, steering wheel and wiring harness mod kit.     - Fog lights?  Nope.  And no factory path to install them.    Sierra HD SLE:   - IMO, the larger radio screen is a much better interface.   - Fog lights?  You can get them.  Steering wheel controls?  Has them.  Remote start?  Yep.  Power driver seat?  Available.       Silverado WT:   - Same as the Pro above however you CAN get factory remote start installed at the dealer for the WT Chevy.     Silverado Custom:   - Comes with 20" wheels only.  Can you swap later?  Sure.  But.  Truck is calibrated for the stock 20s (34" tire) and no path to properly recalibrate.     - Power seat?  Yes.   - Steering wheel controls?  Same as the Pro above.  No but can be done and not cheap.     Silverado LT:   - Same as the SLE.  You can get or it comes with many features you can't do on the lower trims.       I'd say its all going to come down to what you NEED and what you WANT to have that you'd benefit from.  For me, things like power seat is a must (I hate the WT/Pro seating position), so I'd have to go Custom, LT or SLE right out of the gate.  Steering wheel controls?  Should be standard in 2026 across the board IMO, so again, puts me to LT or SLE.

      I have a 1500 but the Custom trim. I bought it solely for the simplicity meaning less electronics. I also love the old school gauges. The only thing that I like about the LT better than my Custom is the front grill. Otherwise, absolutely no regrets choosing this trim.

      2023 DRW Wheel Liners

      By newdude · Posted

      Modifications are required.  2020-2023 the wheel well sheet metal does not have all of the fastener openings stamped for liners that the 2024-2026 dually wells have.  The liners are the right shape and everything, and the wheel well sheet metal is the same shape, its just the older trucks don't have all of the mounting points.     Here's a link to a Facebook post about doing this - https://www.facebook.com/share/p/1Nqow8VNKE/
