Rear suspension rebuild | BMW e46 Compact

Before rebuilding the rear suspension on my e46 Compact, I went out and did some research on parts, tools, difficulty, time, etc… and I realized that there were some informational gaps. This video is an attempt to fill those gaps, providing a real insight into the struggles of a job like this and information about the parts and part numbers.
The video isn’t the best quality, I know. But it’s the result of making it all by myself on a tight time frame, stressed out, working on someone else's driveway, with below-zero temperature. In total, it took me about 20 hours of wrenching to complete + an hour in the alignment shop. The biggest challenges were: releasing the handbrake, removing/installing the axles, and removing/installing the control arms. I wasn’t entirely sure if it’d be possible to do this job without removing the rear subframe from the car, because in every video I watched before starting this, the subframe was always out. But, as you can tell from the video - it is 100% possible. I was also curious if I’d be able to do this in one day, working nonstop. And with the knowledge that I have now, I’d say it’s feasible, but I’d highly recommend doing this with a friend. There are certain jobs, like removing the spindles for example, that would have been infinitely easier if someone assisted me.
To press out the old bushings, I’d recommend buying something like this:

I’m not sponsored by this brand, it’s just to give you an idea. Luckily, I didn’t have to use a kit like this because a friend helped me out with some Mercedes brake pistons, shims, and old ball joints, that happened to be exactly the size that I needed. In the video, I provide you with the dimensions of the bushing so you can prepare the tooling before tackling this job.

Thank for that video, exelent job

Thanks for the comment, glad you found it helpful

It was a good video! An interesting point: The upper outer bush can be inserted instead of the lower outer bush. Its dimensions are exactly the same. In the case of the M3 version, this is the factory solution. The article numbers also match. Maybe the car is a bit more agile, maybe that's why they did it like that in the case of the M3.

Interesting observation! The top exterior ones are spherical bushings (is it the right term?), which means they have a certain degree of freedom. Maybe that allows to fine tune the wheel alignment and suspension on the M3 even more than on the standard e46 chassis

Do i have to release hand brake ? , didnt seen on any other videos they are doing it..

[@alexderkach_]

Yes, that way it'll be much easier to detach the hand brake wire from the handbrake shoe. And then you'll have plenty of room to release the wire from the wheel hub assembly altogether
