Yep in 5th gear speeds mine would have been so much louder. Did you notice a sudden loss of power when the diff broke out of no where?

No it never broke, but I drained the fluid and it looked like metallic paint so I knew it was bad. You might want to do the same for yours but you'll have to refill in the meantime until your new diff is installed.

I know there's one out there where a guy sources a new crush ring and everything and sets it all himself. I found it during my diff fail.

Is it possible to do it at home with a set of common sockets. Just wondering if I should go 3.46 to save the trouble and pay the return Shipping on this 3.38

^ i don't know. if only someone could have posted this answer for you. if only there was a way to use some search terms and enter them to the site Search feature and have results with multiple threads about differential swaps and diff flange swapping. if only there was a thingy, like a com-pu-ter. nah that technology is way far away still.

so until then i'm gonna write on some parchment with a quill and ink and give it to the pony express man to ride to your village. he will be there in about 3 months. it will say how to do this. GL

He's being harsh and only half trolling you. The information is out there though.

I just dont want to mess up the backlash and setting the input shaft. I've read the articles but they aren't clear on that topic. I was told $70 at a local shop to swap the input shaft. I'd rather save the money though

sorry i wasn't sure if you were reading the link i posted like the "DIY: Diff Swap" with all the torques, tools and step by step procedures. and read my post on how to swap out the flanges. but cool, you got the info. you should be fine now. but if any of the reading doesn't seem to make sense, just post the exact thing you're having difficulty with understanding and i'm sure we can explain.

installing a diff with the same type of input flange is easier, yes.
swapping out the input flnage isn't that hard. but there have been people unaware that it needs to be on the same or can wear out the gearing over time quickly. so if you swap the input flange, just follow my instructions and you will be fine. the socket is a thin walled socket. my craftsman worked but some say the ones they had were too thick.
output flanges just pry in/out if needed.
make sure you replace the fluid in the diff as often they come drained. best to have new crush washers for the drain/fill plugs. fill the diff before you install as it's much easier.
if possible get one or two new diff axle bolts. because if one gets stripped you have it ready. also notice those external torx sockets are a unique socket and will need to be bought at Sears, Amazon, autoparts store or Harbor Freight, etc.
axle flange bolts take a splined socket.

Yes I read it. SoI would just need to mark where the hole and spline go into the diff and line that up where the 330i splines meets the diff and install as such? This is my first time doing this

You said to mark the nut and shaft and count turns. But wouldn't the 328i input shaft be shorter so take less? I Must be confused on something about that process.

on the input flange there is a nut holding it onto the shaft. (which is actually the pinion shaft). holding the nut in place so it doesnt spin loose is a bendable "locking collar". you'll need to re-use or replace this locking "collar". about $2 from dealer (after taking off to get nut off).
now what you don't want to do is reinstall that flange nut on too tight as it will pull the pinion gear shaft forward and put too much drag where it connects and meshes with the ring gear. or too loose as the gears wont connect properly. so it needs to have same amount of tension as it had before with the other flange coming from factory. since both flanges have the same thickness's and you're not messing with anything inside just put it back the same. so this means after swapping input flanges put the nut back in the exact same place and turns. this is why you mark the pinion tip (top of shaft where the nut screws on) and count turns to take off. then after swapping flanges, just put back same exact full turns (example 5) and end where the line is for edge of nut and a mark on the shaft that was directly adjacent to your mark on the nut's edge. some make a mark with sharpie. i do it with a center punch (or scribe) to make two dings in the metal that i can see and align later.
now this trick works for input flanges. but not if you're installing a LS unit inside or messing with the internals. which you are not doing.
