In Part-2 of this two part series, we will replace the rear shocks on a typical BMW E90, E91, E92 and E93 3-series chassis (06-12). See Part-1 for the front shock/strut assembly replacement.
The Bentley repair manuals will cover standard shock and spring replacement for the various BMW and MINI models. This DIY will assume that the DIYer has the applicable Bentley manual for additional reference as well as fastener torque values. Note that we will be installing the Koni Sport shocks. However, the procedures would be the same for any common shock/strut replacement.
PARTS USED:
• New shocks/struts (Bilstein, Koni, Sachs, etc.)
• New Shock install kits (compression bumpers, dust shields, spring pads, etc.)
• New upper strut and shock mounts
• New strut & shock mount gaskets (as required)
• Rear shock mount reinforcing plates
TOOLS USED:
• Bentley Repair Manual
* BavAuto spring compressor tool
• BavAuto Non-Marring pry bar set
• 13mm through 18mm ½"drive socket & ratchet set with various extensions
• 4mm through 8mm Allen keys or bits (for ratchet use)
• 13mm through 18mm combination wrench set
• Assorted flat and Phillips screwdrivers
PROCEDURE:
REAR (applies directly to the E90/91/92/93 3-series)
1) Safely raise the rear of car, with suspension hanging.
2) Remove the wheels.
3) Remove the lower shock mount nut. Hold the shock body with an open end wrench to prevent it from turning.
4) Remove the trunk side trim panel. We found that we could simply remove the fasteners on the forward half of the panel and fold it rearward (via the access through the fold-down rear seats).
5) Remove the upper shock mount access cover,
6) Hold the shock shaft with a6mm socket or wrench and loosen the shock mount nut. Remove the nut and attached bushing.
7) From under the car, compress the shock by pulling down on the upper section. Pull the shock out of the mounting hole in the shock tower and remove the shock from the suspension area.
8) Install the new compression bumper and dust tube on the new shock, along with the new lower half of the upper mounting bushing assembly.
9) Install the new shock assembly into the lower control arm and the upper shock tower mount area. Compress the shock to install, as in step #7.
10) Install the lower bushing nut.
11) Install the upper nut and bushing.
12) Install the shock mount rubber cover.
13) Install the trim panel.
14) Repeat for the other side.

Very good vids, I just did the rear of my E92 over the weekend (shocks, springs, M3 control arms) and will be doing the front shortly. I'll be using the front end vid for reference, great job! Oh, and for the previous commenter I'm doing this in my garage with floor jacks and jacks stands, its a pain but very doable.

Thank you for the very clear step-by-step procedure, you made it easy to remove and installation plus simple techniques in removing the front struts by turning the wheel so that strut would drop down and clear from the fender for the strut to remove. I appreciate it very much and soon I'll be doing this task to my BMW 335i

Fantastically clear. You have a gift. Would you mind please doing the same for the wagon? The E91 has a horrendous set of housings and panels needing to be removed-just to get to that shock bolt. I figured it out. But it’s more complex than the sedan.

Hi Otto, Regarding the refitting of the trunk side trim panels: for a 2011 E90 without folding rear seats, what is the trick to reinstalling the trim panel forward edge(s) behind and between the fixed seat trim and the back of the seat? Also, thank you for all the excellent blog videos!

I noticed that BMW publishes a torque for the upper shock mount nut but no one does this in any of the videos I've seen. How is one even supposed to torque the upper nut and counterhold the shock at the same time?

Pretty good video. I was wondering this will work with the BMW e90 in the U.K.?In regards to the springs. Would I need to do anything with them? Sorry to sound silly but I'm thinking in changing my front shocks myself. Also how did you lower your rear seats? I had the assumption you couldn't. Cheers

I would remove the shock (as shown in the video) and inspect the lower mount bushing (in the control arm) and the upper bushings. Also inspect the shock itself. Additionally, inspect the swaybar end link for worn joints that could be clunking,

Thank You Very Much For This Informative video. My only question is, I have a 2006 330 XI E90 and I mistakenly bought Koni sport shock. I want to know if I can use them with the original springs or not before I pay for returning them. Thanks in advance

@bavarianautosport 10 жыл бұрын

You can indeed use the Koni Sport shocks with stock springs. We suggest that you start with the settings full soft and adjust from there, unless you know that you do indeed want the shocks substantially firmer. We would not suggest starting at more than 1/2 between firm & soft.

This is the nice video with clear discription. However I'm thinking about my E87's strange sound from left rear footwork area while watching this vids. Which sound like light noise when I runnnig bad road surface, also when I jack up vehicle sound like metal be rubbed with stretching absorber. If you have the opinion, please give me the idea.

@bavarianautosport 10 жыл бұрын

You may have a shock, shock mount or control arm bushing issue. We would first suspect shock and shock mount as potentials. If you can hear a sound while jacking, work on locating that sound.

When I turn the steering wheel to left/right it clicks(clicking sound). They said that its because of suspension is that true?

Sounds like your axle on both sides need replaced.

@bavarianautosport 10 жыл бұрын

This is really an "it all depends" question. If the vehicle (and the shocks) have low mileage, then a single replacement would make sense. However, if the shocks have 50,000 miles, or more (for example), a new shock will likely have different damping than the old one, due to normal wear of the old ones. In this case replacing in pairs would be the best choice. If finances don't really fit this, nothing is going to be damaged or be unsafe if just the one is replaced, for now.

Recommendations on mileage to replace shocks?

@towhee7472 3 жыл бұрын

A little bit late, but the range is usually somewhere between 30 000 and 60 000 miles. I traveled long distance most of the time, and I got 60 k miles out of mine, until they started to go bad and fuck up the ride comfort.

Can bad bushings cause a squeaking noise? There is a squeaky noise coming from the right rear end, I believe its the lower lateral to chassis bushing that's gone bad. And does the up arm have a busing in it?

@bavarianautosport 9 жыл бұрын

All of the rear arms have bushings at the inner pivot points. Yes, a bushing could cause a squeak. Does the squeak happen if you compress the suspension when the car is at rest? If so, you can get the car on a drive-on lift and bounce the rear end while locating the noise from underneath,

@Xb0XyOuRmOtHeR 9 жыл бұрын

Yes the squeak still happens. I pushed down on the trunk and the squeak is really bad and quite loud. The bushing on the Lower rear control arm does look pretty bad

@bavarianautosport 9 жыл бұрын

Jusuf e90 You should be able to fully locate the source of the squeak if you can push down on the trunk and make it happen. It's best to be sure before diving in.

@bavarianautosport 9 жыл бұрын

Jay E90 That could certainly do it. If you replace the bushings, you may want to consider the rest of the busings .... as long as you are up to the extra work and can handle the extra expense.

@soloflexx4256 5 жыл бұрын

Good video. However, i'm having trouble figuring out how to change the shock mount. I'm not able to figure out how to reveal it. But i'm certain that it needs to be changed because my shock sticks out about 6 inches (if not more) higher than yours does in the video. Also it rattles as i drive. Any ideas or videos that show how to reveal the shock mount? Thanks.

@klchew88 10 жыл бұрын

Doesn't the rear absorber extend itself after compressed due to internal gas pressure? Why do u need to help it to extend?

@bavarianautosport 10 жыл бұрын

Not all shocks will have enough extension pressure to fully extend into place, without help.

@oliverspencer921 9 жыл бұрын

BavarianAuto It's because the control arm was hanging too low - the strut would have to bend to fully extend. The lower control arm should have been raised a bit and THEN the shock would have extended, allowing it to be tightened.

what are the torque specs

@VKMFA Жыл бұрын

Sorry, but I can't tolerate neglecting 1) torque specs. 2) you must tighten a lower bolt on the vehicle's ride height. The manufacturer sets these parameters for a reason. As an engineer, I spend an enormous amount of time ensuring the part performs at its best. But this is impossible if you do not follow the instructions. And then people say BMW is unreliable. No, the so-called "expert" car mechanics ruin them.
