    Hey guys, For a few months now i’ve been facing a problem where my 2003 320d automatic starts vibrating from the rear under load. At first I thought it was my driveshaft. While changing the driveshaft i discovered broken transmission bushings and change them hoping it to be a solution to my...

    Hi all, I have a 2003 320ci (ZF 5-speed auto) and I had the wheels off this past weekend to do a couple of things. While it was on stands I serviced the transmission and while cycling through it, in drive and reverse I noticed my diff was locking up randomly. So I'm on the hunt for a new diff...

    Alright the time has come, i'm coming upon the dreaded rear subframe drop that everyone knows and loves. I will be dropping my subframe sometime in this next month as I have caught up on pretty much all the maintenance this car has been asking for. The car is an 02' 330ci with the beloved 5spd...

    I’ve been going back and forth on this decision since 2021 and I still don’t know what’s the right thing to do: 2005 BMW 325Ci with an open diff (correct me if I’m wrong). Car has over 200k miles, I have 0 idea if the previous owners had ever replaced the diff oil. I’m refreshing everything and...

    Hello hello, What could cause this knocking sound? It used to only appear when i had my foot on gas but few days ago when I got to highway and went full throttle, there was this extremely loud bang and the knocking sound started being continuous, much louder and more metallic-ish. Only thing I...

    Why does the rear of my car start to shake when I shift and when I let off the gas ?

    hello everybody. I was swapping my diff when i realized that my half shaft was rubbing on my upper control arm, causing a mark and also making it extremely difficult to install the diff. I sat under the car for a significant amount of time trying to figure out how this was happening. I then...

    Hello, I recently purchased a 2005 325xi. I needed a car to move to alaska with and I found this one with less than 150k on it for $3k. Immaculate interior, no dents or rust, no lights on the dash(besides washer fluid level). I was especially happy to find this car because I had had an E39 in...

    Yeah I know, it’s another diff question I’m sorry guys. I’ve been doing a little bit of searching and I’ve seen lots (and lots and lots and lots) of discussion about the practicality of using the 3.46 diff and whether or not it’s ratio is too short to be useable for daily driving, but that’s not...

    So I’m trying to figure out what diff I should go with for drifting. I currently have the stock 3.15 ratio welded up and it works but I was wondering if a 3.46 would be a huge performance boost for drifting. The events around me are kinda all over the place. I’ve been to one that seems like a...

    Hi all! I have just acquired my e46 323i manual convertible and starting my drift build, so far I have found so much useful info here and was hoping to get some specific help on the diff. so, if I’m right I have a 3.07 ratio medium case (188) diff? I want to get a shorter ratio to get more...

    I’m looking to get a LSD for my 320ci. It says it has a 188k and I just want to be positive it will fit. I’m looking at getting this one that I will link. Thanks http://www.mattlewisracing.co.uk/product.php/2899/1197/limited_slip_differential_bmw_1_3_series

    How does the E46 open diff work?
  18. E46 General
    Hi guys.. Got a big knock sound (and jolt felt) when shifting from Drive into Reverse and vice versa. Just had the Diff mount changed which was on its way out but the issue remains unchanged. Got told there is a bit of backlash in the diff and an oil change might help. Any experience of this...

    Recently did some work to my diff including replacing the halfshaft/output seals. After a while I noticed they were both leaking but I can't figure out why. When installing them I used a bit of diff oil as lube and just slowly hammered them into place with a mallet and blunt piece of metal. Only...

    Hello, I have an e46 touring project and I need some info. I wanna push 600 hp out of an m52 and I know the rear ends fail, so I was gonna do an m3 full rear end swap as well as reinforcement plates. Does anyone know if the rear end swap will affect my compatibility with my coil-overs or will I...
