Question about 1987 190e-16 Suspension - PeachParts Mercedes-Benz Forum

Niki · #1 03-04-2008, 01:39 PM

Greetings! I have a 1987 190e 2.3-16 5 spd that I recently purchased that I am trying to become familiar with (the Merecedes service manual is en-route!).
This is probably a stupid question but this is my first Mercedes & my first experience with this type of suspension. (Not to mention my first time on a forum)

.
The car sags in the back end. When I purchased it about 3 months ago, the tires were good all around. Now my back right rear is completely bald & the driver's side is well on it's way. Fronts are good. What could possibly cause this? Can it possibly be related to the sag in the back end?
I suspect there's more to it after reading through this forum but need some sort of direction.
I appreciate any input!

When the rear sags the rear camber goes negative, too much negative rear camper will wear the inside edges of the tires.

Have the hydraulic Self Leveling Suspension (SLS) inspected, including the engine mounted pump, the hydraulic lines back to the rear, the nitrogen cells on each side of the rear suspension; the leveling arm and the rear hydraulic shocks as well.

I doubt a 190E has the self leveling suspension system....the 190 was the "cheapest" MB available at the time.....

A 190E 2.3-16 has the SLS system.

all 190E16v had rear self levelling, unless it was removed, see picture below, pump and reservoir are marked

Sorry for the off topic, but Wow, Stone Brew! I really enjoyed your beers when I was assigned to 29 Palms, CA. I'm missing it here on the east coast. I am advertising with my Arrogant Bastard shirts and glasses though. Get that beer out here!!!

The 2.3-16 had an MSRP of $35,400 in 1986 and $40,300 in 1987, compared to $24,300 and $27,100, for the 190E 2.3L.

Thanks to all for your advice!

WHunter, thank you for your help in navigating this site.
No, there are not lowering springs. However, I have been reading about this system & have discovered that the adjusting lever was broke. I have purchased a new one. FYI, not sure where I read it but someone claimed theirs broke as well & the part for a 300E was the exact same part (only $50 less) than the 190e so that's what I bought. Ended up having to purchase the bracket as well (long story & too much rust). Anyway, bracket is on order. Am curious if any of you have attempted to replace either of the suspension lines as I know I have a tiny leak but won't know until this weekend which
line it is. I would like to fix it properly if at all possible.
Thanks for all the help!

It was easy. When I rebuilt mine, I bought new spheres, shocks, lines, washers, etc. Cost a little money, but teh original set had almost 20 years on them. So I figure I'm good for another 20.

Use proper line fitting wrenches and the proper MB Fluid. The system is self bleeding, but may take a while to get all the air out. A bunch of people in the trunk helps.

Does anyone out there have a GOOD picture of the suspension lines. We went in to "repair" a line that has a tiny hole in it & the line turned out to be only about 14" long (running from the valve to the accumulater on drivers side). So I just decided to buy a new one & do it right. However, when I got pictures from Mercedes, I cannot tell which line I need to order (even standing at the parts counter at MB with the line in my hands & they didn't know). Is this a line I need to bend myself? The line they show looks nothing like what I pulled off my car. Also, this line has inside of it another line (like a thick wire) running through it? I was wondering what the purpose of this is?
Thanks for the help!

I'm looking at EPC online. Looks like 80 is the pax side shock line, 83 is the driver's side shock line, 56 is the line to the pax accumulator, and 53 is the line to the driver's accumulator. The banjo bolts are 86, and the copper washers are 89. It's pretty clear in the pic to me.

I would get new washers too, minimally.

I have no idea how, or even if you can, post a pic of the diagram here. can't figure it out.

Check out the online EPC. It's a free service of MB. Search this site for the link to the sign up page.
