Hello guys! Recently I bought a really nice and well kept E46 touring which has xenon lights. One of the headlights had a pretty nice white light while the other was slightly yellowish. I assumed the bulbs are different, so I bought a set of two expensive genuine Osram bulbs (both sold as a...

Hello guys! I just bought a differential, and I can't find what ratio does it have. Can somebody help me out please?

Hi Guys, I'm a little lost on this one. I've installed two new rear diff bushings (along with new front ones the first time) in my e46 320i over the past year and both have leaked after only a few days of being installed. I used a bushing press tool which I'm confident wasn't pressing on the...

Hi! This is one of my first posts, my name is Brant and I have a 2002 325ci 5mt with the ZF 5 spd swapped in. Lately, I have been plague with this god awful noise that is impossible for me to find and diagnose. When taking off from a dead stop about 50% of the time I get this audible but loud...

I am thinking of purcahsing an E46 M3. Here is a picture of the under carriage of a 2003 E46 convertible taken from the rear of the car. I'm not sure if that's oil on the bottom of the differential cover (?) - do you see anything wrong? Apologies but just have this one picture to share.

Just bought a 328i. Clunking noise coming from rear end when putting it into first gear, when shifting from first to second hard, and really whenever a load is put on it. went under the car and the axles have some pretty decent side to side play. differential bushings dont appear to be destroyed...

Hey guys, Sorry if this sort of problem has been addressed before but I haven't managed to find much information that's useful for me from searches. I've got what I feel like is a lot of radial play in the driveline of my e46 320i. Along with this, I've got quite a clunk from the rear of my...

Hi fanatics, What is the correct amount of new fluid to put into the front and rear diff? While most DIYs just say to drain it out and fill it up again until it drains out of the fill plug, I saw some comments that said there is a specific amount that should be re-filled, and that filling it...

Hello! this is my first post on the site and I have hopefully a quick question. I have a 2003 325i, and I'm planning on switching the stock 3.08 diff for the auto 3.46 diff. I also want to make the 3.46 an LSD, I'm looking at 1.5 way LSD's and just making sure that I'd have to buy the LSD for...

First post on this site, and I'm sure 100 people have posted this exact same thing (so my apologies in advance), but i find the search function in all forums frustrating. Even if someone can link me to good threads i'll be happy :) Brought my 2000 323i (175k km)(manual tranny) to about 3...

Hello. Does anyone know if the rear axle carrier from a 320d (OEM part 33316770830) bolts on a 318i. I know the diesel axle carrier has two extra vibration absorbers ( 33311092256) but i'm hoping that the mounting point distances to the chassis are the same. Has anyone done this? Thanks.

Hello all, I just picked up my first E46, an '04 330XI Automatic. I’ve been looking at a Coup/M3 for a while but haven’t been able to pull the trigger yet (wife…child…). I happened across this ‘04 by chance, which are always the best deals, and seems to be the perfect winter car, and I...

Hi, I recently bought my first BMW and got very low knowledge about BMWs in general hence why I am here :) I just bought a differential from an automatic with the ratio 3,73 and mounted it onto my BMW. Now i need to make my driveshaft just a tiny bit longer and im quite confused. From what i...

Hey everyone! i have tried searching all over the world wide web without succes :facepalm: as the title state i want to replace my old diff with a higher gear, i'm driving with the stock 2.93 want to upgrade to 3.23. both the 323Ci M52 runs with 3.23 and 316 M43 runs with 3.23. what i know...

Im thinking of doing a diff swap on my 323i 5 speed. I am unsure on a few things though. Can you use a diff from an automatic car on a manual transmission? Does the diff from 325 or 330s fit onto a 323i drive shaft? Do any other car diffs fit on the 323i? What would be the best place to get a...

So all of a sudden, my car started making a noise from the rear. It sounds offset to the right slightly and it's almost like driving on studded tires or like the engine revving up, coming in around 20mph, and getting higher pitched as the speed increases but only a little louder. At 50 or 60 it...

I've searched up and down the forums for an answer to this question but I haven't seen anyone answer it, I know that a E46 M3 diff won't fit on a non M without having a whole rear assembly and subframe come with it, but can you just take out the actual LSD spool or unit out of the diff housing...

Can you swap a us spec diff with a euro sec diff? Ive read euro is a little bigger. If it is swappable am I looking at clearance issue? Maybe a new drive shaft?
