Hi,

I am trying to figure out where to buy a replacement rear differential fill plug for a 2002 trailblazer. I stripped mine and have been trying heat and pb blaster but not budging at all. I am having trouble finding it on any websites. If anyone can has any information it would be greatly appreciated.

Try your local Chevy dealership parts department. That's where I got my replacement rear differential fill plug about 2 years ago. Was not expensive at all - around $5 if I recall correctly. I believe the part number is 444788
