My 05 had the updated part. It probably depends when exactly an 05 was built.

I will have to look at the part number off of my old one and compare to the new one tonight.

The number on the side of my OLD Diff Support Bracket #2 is 52391-60021. I will be taking off the front skid plate this weekend changing the oil so I can get the number off of the new bracket.

Well I need to verify my order receipt. Because I just checked my new bracket and it is the same freekin number that I pulled off! It should have been 52380 but it is also 52391.
You might have the updated part already?

That’s what I initially thought and was going to appoint myself the stupid award. But then looking at the first post the PN should be different.
So going to have to find my receipt and verify what I ordered exactly.

OK just looked over that link and they do appear to have the same part numbers for some reason. So I guess you really do need to compare them side by side or save those pics in that thread to compare to your existing one.

Do skid plates help prevent catastrophic diff failure if the old diff bracket breaks in half? Im not sure what’s the gap between the old diff support bracket and the skid plate.
I’m asking this because @DanKunz drove with it cracked for a while. In his case, he just experienced vibrations and extra alignments.
So, I don’t get what the catastrophe is with the diff if the support bracket breaks.

Mine cracked but I didn't wheel it cracked. I was just street driving because I couldn't find the issue. If you wheel cracked the damage comes from the diff deflecting UP and into the oil pain, as well as eating the CV and possible the R&P.
Got it. It’s on my list of things to do but wasn’t sure the order of priority compared to other things on my list...which never seem to end!

Dumb question but is it just the passenger side that gets replaced?
On my the rubber grommet has deteriorated so even if it has been replaced it seems you just can’t get the grommets.

The passenger side was the updated part, yeah.

There is a picture of a washer that needs to be reinstalled when the new diff support is installed. That washer is not a wear part or do you re use the old one?

Mine was in decent shape so I re-used mine.
I ordered the new part number (or so I thought) and received the identical part as the one on my car. At least it looks identical, same thickness, so I didn’t take it off - because from the pictures here the new upgraded part looks thicker. I bought 52380-04071 and they sent 52380-04071 but it looks identical to my old part and the part number stamped on the side is the same as the old part number 60021. Did I buy the wrong part? Here’s what I ordered.
In the link above, they said the 04 V8 has the beefier one already - so I guess I have a spare too.
Can anyone measure the thickness of the new one so I can confirm this?

Correction:
Part ordered, 52380-04071 supersedes 52380-60021
Part number stamped on part: 52391-60021 and is 1.148” thick at the widest point and 0.994” just behind the stamped part number. Approximately 0.872 measured metal to metal where the rubber bushing fits. It also has the 6 stamped on it. I know my old one had the 60021 stamped on it, and when I held the new one up to it the thicknesses looked the same but I didn’t remove it to compare.
Can someone measure the old weaker one?
Below is a picture with measurements of the new one.
