I recently changed the fluids in the transfer case and noticed that the plugs are pretty mangled, and I don't want to risk stripping them next time. I ordered these two from Amazon to replace the fill and drain plugs but even though they should fit according to Amazon and Rock Auto, they aren't even close. They are so much smaller that they almost fall through the hole they are supposed to thread into...Does anyone have any idea where to find these? Here is what I bought before:

Here's what I found on GMPartsGiant; fill plug and drain plug are listed as the same part number. Not sure if you can find them at a local dealer or not; that might be your best bet.

@Fless beat me to it. Same link.

By the way, your title says "bolts" and then you ask for plugs. Slightly confusing.

Looks like they both take the same plug.

Thanks for posting, this was super helpful! I stopped by my local Chevy dealer and they special order them. The part number they had matched the one you sent.

The plot thickens. Got these ordered a week ago, and picked up from the dealer today, only to notice that they were about a third the size that they need to be. Before ordering, the GM parts department confirmed that that was the right part for my transfer case, so based on what the numbers say, this should all be correct.

I can confirm that the following do NOT fit the transfer case for the 2012 Yukon XL Denali:

15032997
19133162
88984495

Not sure what else to try at this point, Maybe try a set of threaded pipe plugs and see if any of those fit?

Try an auto parts store. They should be able to match them. Even if they take a socket/wrench to tighten, instead of the 3/8" drive. They just point backwards and not to the ground.

I can't remember which ones are on my transfer case. For some reason I'm thinking they're the larger ones also, that take a 1/2" drive to remove/install.
