ML320 Shocks... Do it Yourself. vs Pro
 

My Mercedes dealer wanted $1600. to replace the rear shocks.
Because one squeeked.
--
I bought one shock for about $140. as only one made noise.
--
When the weather breaks I will let you know how it went.
The $1400 savings will take my family to Florida for 2 weeks.

It's 12 degrees in Michigan.

Come March I will install (or attempt to ) the shock. I cant imagine it taking more than a half day.

Life is full of choices.

Fast Robert, you do not need the bump stops on the Bilsteins. Bilsteins have internal bump stops.

Toad,

Didn't know they had internal bumpstops. The MB bumpstops and front shock bushings from the OEM shocks are MUCH better quality than the garbage included in the Bilstein kit. I reused the stock pieces. Best to be safe than sorry.

Steve,

Glad to help chief.

Re: Re: why are you changing the shocks?
 

At 54k ours are feeling pretty spoungy as well so when it returns from the body shop this will be something that will need to happen.

Are there good aftermarket shocks for the ML? Ride is of the most import as it's used for rural road driving, improved anti-roll would be nice as well.

Nice to see some pics/diagrams. Thx Tabo and thanks Gilly for the R&R info on the rear. I would not have gone after the lower control arm right off the bat. Front's look pretty simple.

Anybody have the torque spec for the front shock?
 

Thanks,

John

Rear Shocks
 

Fast Robert Sent Me Pics On How To Replace The Rear Shocks. Was Going To Do It Myself But I Asked My Local Mechanic Here In The Middle Of Nowhere And He Said He Could Do The Labor For $160 So I Said Absolutely. He Did It For That Amount And Said It Really Cost Him About $220 In Shop Time But He Stuck With What He Quoted Me. I Thought That Was A Hell Of A Deal. New Bilsteins, Rides Nice, No More Creaking And Groaning.

Part numbers for rear Bilsteins ?
 

Apologies for joining this discussion late ...

First off, I have the famous rear creaking which my shop says is from one of the rear strut joints. Is the joint the source of the creaking or is it the shock itself?

I'm hoping that replacing the shock will fix it - previous messages seem to indicate so.

However, I'm confused about which shocks to order ... L4000-86676 or L4000-159265. Do I need the strut and spring assembly?

I guess it depends on the chassis number. How do I find the chassis number of my car (2000 ML320) from the choices listed?

-A 145272
-X 707755
A 145273-
X 707756-
-A 093893

Any help would be appreciated.

shock
 

Bet its your shock.
Mine creaked- bought a bilstein for $140 ish plus shipping, paid a muffler shop $40 to remove Coil-- and reinstall it on the aftermarket.

THEN I bought a pair of NEW Mercedes shocks W/ coils ---waiting for the other to make noise, which it has not 20,000 miles later.

Want to buy one ? $200.00

Shock
 

Thanks Steve, but I'm going to do both rears since I have about 70k on them. Can you tell me which Bilstein shock you bought?

I've found two part numbers for a Bilstein rear shock without the spring:

BE5-2985 and L4000-86676

It's probably the same part, but I'd appeciate you confirming.

thanks,

Ken

Just replaced both my rear shocks
 

I just replaced both my rear shock/spring assemblys last weekend. I have a 1999 ML430 with 84K miles. The right rear was creaking loudly so decided to replace both rear shocks once I was certain of the noise source.

I did the whole job myself for a total of $116 not including my time. I decided to go the easy route and order the OEM (Sachs) shock/spring strut combinations pre-assembled, they were $58 apiece online.

Mercedes part # 163-320-23-13 or
Sachs part # 290-055

Although the shocks and springs came assembled it was not a quick replacement. The three top nuts securing the top of the shock assembly are had to get at, especially the left rear because the fuel inlet pipe is in the way. The spare tire and carrier must be removed to get to these nuts (as stated in other posts it is critical to have a ratcheting 13 mm offset box end wrench).

On the left rear I also removed the fenderwell plastic, which helped a little. Once the lower control arm is disconnected from the frame there is plenty of room to work in replacing the shock. The torque values are listed in other posts.

Bobby - Unbelievable Price
 

Your Price just Blows my mind.
The dealer wanted about $1500 to replace mine.
I thought the stock shocks sold for about $500-$600 each.
Did you buy them at an auction ?

OEM parts ordered online
 

I ordered them from an all OEM parts store online.
I found a couple real quick.

Example, go to either of the following sites (there are many more)

http://catalog.peachparts.com/
http://www.thepartsbin.com/

and type in the Mercedes part # "1633202313" in the part search field.

Note: To ensure an accurate part number, get it from an authorized Mercedes parts dealer prior to ordering and be sure to provide the VIN when requesting the part number.

Shocking
 

At the parts bin the 1999 ML320 shock complete with coil spring it is $335.48 each.
The Bilstein is about $160. with no spring.

Yet typing in your part number brings up a shock at fraction of the cost of the others. I am flabergasted at the price.

Shock Quality
 

I Would Be Suspect Of The Oem Shocks, The Creaking Noise Is Caused By A Wore Out Bottom Bushing On The Assembly, When I Replaced Mine With Bilstiens And Removed The Old Ones, The Wore Bushings Were Completely Sloppy And Had A Ton Of Play. I Can't Believe They Did Not Make More Noise Than They Were Making.

I saw this and thought that perhaps the spring/shock set was cheaper because it is the older, outdated part number. But, I checked the part number "1633202313" on Wolfgang's site and it says that this is the correct number for the replacement (new and improved) spring/shock set for a 99 ML 320.

Amazing what a little knowledge and searching on the internet can do :)
