    2.93 Differential Does anyone know if the 3.88 shim goes on the ring gear side or opposite? Mine has a 3.88 shim and a 3.42 shim. Yes, I should have marked them, etc…. I know. I thought it was going to be a same day rebuild while putting in my helical lsd. It wasn’t and now things have been...

Now there is a big head diff with diesel driveshafts and I need to know, because im going to swap it for normal small head diff 3.45, are only...

    Hello. I have a compact 318ti e46. I replaced the engine with a m54b25. The gearbox is the Getrag from the 318i. I use a differential from the 318ti engine (N42B20). Since I keep breaking it, I bought a 188 type differential from a 323i. My question is what dtiveshaft should I put in to...

    Hello, I would like to know if anyone has experience or knowledge about swapping 3.38 diff to 3.07 diff with a 105 horsepower engine. Will it be more fuel efficient, and will it be enjoyable enough for a daily drive? I know that Vmax will improve while the torque drops

    Hi I’m trying to install a mfactory helical diff in my 325ci I bought the mfactory shim kit but I can’t seem to get my backlash tight enough even when using all the shims the backlash is wayyy to large. Also when I use all the shims it leaves no room for the cclip anyways. iv been tryna rebuild...

    Hey guys, I just bought a 2001 320ci manual and it clunk's whenever you change gears or go on and off the throttle hard. You can drive the car smoothly and it makes no sound. Today I looked under it and told my brother to brake and release clutch to see if the bushing of the differential were...

    Hey Guys, I'm chasing quite a severe drivetrain slack that my manual e46 320i (215000 km) has. I'm looking at the diff and can't find any information on what an acceptable amount of backlash in the diff is. I'm assuming that the differential should have close to no backlash at all (at least...

    Good day everyone. My Diff has a little too much play on the passenger-side and is beginning to make noise at high speeds. To that end, I have resolved that I will have to have the diff rebuilt soon and am using this as an opportunity to do someupgrades. Other than the 4.10 ring, what LSD...

    I have noises at low speed when turning in car parks and such, sounds like something is scraping on the ground. there's also a big boom when I go on/off power at speed. I've read that the M3s used to have these problems and it's an LSD thing that BMW fixed but of course I have an open diff...

    This issue just started tonight with my car as I was driving home on the freeway. I tried to accelerate to merge on the freeway, and as I was accelerating, the car would violently shake in the rear, almost the same feeling as like a burnout or a launch. But, my tires were not spinning, obviously...

    Hello again, just wanted to get another opinion on what could be wrong. Today I have been messing around quite a lot and did many donuts and burnouts (I live in Seattle so it rains a lot). The car in question is 2004 330i Automatic. Towards the end of the day I had a wired issue occur. After...

    Hello everyone, I drive 04’ 330i automatic. I bought it off an an auto auction and it has a lot of mods. Sway bars, Coil-overs, lowering springs, Strut bar, Wheels, K/N Cold-air intake. Some kind of tune (Car is faster than other 330i’s, have tested), Air vent gauge. Lately I have been messing...

    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...

    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...
