So I'm buying two new differentials, because I know these two are messed up in some way, I can't see it, but I know something's wrong because it's ticking like mad, and this is where it's coming from, so all I need to know is this; This is my [rear] differential:

It has two screws on the top, and I was wondering if this differential; would fit the same?I don't think it will because of the fact that it has 4 screws. My truck is a 4909 version, and I have a feeling that the differential from that pic is a 4010, from the .15 classic t-maxx, My truck is a 2.5 and I appreciate the help

What version of the maxx do you have? The 4909 or 4908? If it is the 4909 version then yes, it will fit. The 4908 however uses revo diffs and are a lot stronger and slightly shorter so it wouldn't work in that app. I would say shy away from a 2.5 diff. If you have a 3.3 and it's blowing 3.3 diffs why put a weaker diff in it? Buy the 4908 diffs or revo diffs and just buy new centers.
 
Well I'm almost positive it's the 4909, because I got this truck in '03, the 4908 wasn't even out then was it? And by the way, the differential in the Ebay Add is a 4910 it says, on the top, so are you still sure it will fit in my blocks and on the truck the same as mine?

Oh yeah, the ebay link wasn't working, so I just put a pic on there instead, And on the ebay add on the title it says it was for t-maxx 2.5, 3.3, or the E-maxx and it said "4910"

Yeah it was a 4910, my bad, so your saying that that's the .15 custom t-maxx? and it WILL fit in my 2.5?
 
I was told the 4910 is the first T-maxx version and had the Pro .15 engine but from searching Google just now it seems the 4910 is the first 2.5 version before the 2.5R. The diff will fit.
