i have an 2013 gmc 2500 hd and recently came across a screeching noise when i turn the heater on. I believe it is not the blower motor as when is it on cold the noise goes away. I am lost on what to look at next.

I would drop the motor out & check it out.

See if it turns freely. Inspect the "squirrel cage". Look for debris or trash inside the air duct housing too...

  A 5mm slip on spacer is no big deal. I run them with my summer aftermarket 20" wheels. There's a LOT of thread still. It's not like you only have 3 or 4 turns of the lug. Been running this setup every summer for the past 5 years with no issues. I run true spacer/adapters in the winter with the stock wheels. 2" spacers that bolt on to the stock lugs and wheels bolt on to the lugs on the spacers. Again, 5 years with no issues.

  $3.69 for 87. $4.09 for Diesel. Same thing though, a few cities away or even into Wisconsin it's $5.00 a gallon still and they all get it from the same damn place.

  I caught three different videos, Lake Speeds and two of Gregs videos on the weekend and I instantly thought of your truck and if you had heard about these items yet which is why I took a peek in the 1500 series just now. Some very interesting findings were discovered by the looks of it and I was shocked at the results from the oil testing as the low engine speed with high torque load places a very different load on the bearings and hits home that viscosity certainly has relevance depending on the engine type and its operating speed and load.
