Renewed front suspension feels amazing

I refurbished my (84 300D) entire front suspension this last week (finished last night) and it feels amazing! The only problem I have now is that my rear suspension feels terrible. Which only means I need to do that soon.

New:
-springs (Lesjofers, dealer was cheapest)
-LCA bushings w126 style (Lemforder)
-Guide rod mounts (Lemforder)
-Guide rod bushings (Karlyn)
-UCAs (Lemforder)
-UCA bushings (MB)
-Lower ball joints (Lemforder)
-Drag link (Lemforder)

I stripped, wire wheeled and painted the hubs, LCA, brake disc cover, and guide rods with black undercarriage paint.

Shocks were Bilstein (1 year old) HD.

$525 + back breaking labor = 1 happy daily driver.

Sweet. I have a parts pile growing to do just this job on my '85. I'll be replacing those same parts, and also be renewing all the steering components (tie-rods, etc) and installing new Comfort shocks. I also have all the parts to do the rear.

I think I'm going to start with the rear on mine, since a spring compressor isn't needed. And the rear is worse on mine right now than the front. The only issue up front is a creaky noise going over speed bumps when the car is cold. After the suspension moves a bit it goes away. Out back, I get annoying plastic rattling noises (likely from the shocks, already renewed the sway bar links), and the rear suspension makes undue amounts of noise over harsh roads.

Anything in particular you ran in to that was memorable?

All that new stuff combined with a properly done front end alignment.... you get to experience all that German OCD engineering put into these old cars....
I am so glad you included the new springs.... they make more difference than most people realize....

Agreed about how the car feels after a front suspension rebuild. I have done several, and the results are just amazing: 123 Suspension (Front End) Rebuild
It makes the car feel like new!
I recently got a spring compressor:

and replaced a friends front springs:

I had to cut the corners off the top disc so it would fit the top of the spring perch:


The funny thing is, just a month ago I rebuilt the front end on this car, and he decided afterward that he wanted new springs. We did the rear springs, subframe bushings, and diff mount a couple weeks ago as well. For others contemplating on doing this kind of work, a quality spring compressor is worth it's weight in gold. Thankfully I did not have to learn this the hard way, as I have successfully compressed many springs with the other type (threaded bar with hooks) without any issues. This new compressor works great and I am thankful to have it......Rich

Interesting, why did you have to cut the compressor disc? Something special about the W123? I've used mine (very similar looking case to yours) on my 124 and 126 and had no problems. We compressed the spring somewhere in the middle and not up as high like your photo shows.

I bought parts for the 85SD but didn't think about springs. Is the experience that they need to be replaced at 200,000 mi and that OE replacements are the way to go?

I would. I would use whatever springs the EPC points system ends you up with as well as the correct pads. If the EPC does not list the values out than the FSM will.

I wonder how a new suspension w123 compares to a W124 - when I did the front and back of my W124 - the car had an entirely new personality. Almost nothing drives like it.

Congrats

One question. You noted your springs were from Lesjofers and then commented the dealer was cheapest. So the springs from the dealer are stamped with Lesjofers as the manufacturer or did I read that wrong?

Question Número Dos

You've used Lemforder or MB parts except for the Karlyn guide rod bushings. Why did you use the Karlyn parts? Thx.

The hole in the disc would not line up with the hole in the spring tower without cutting off the points of the disc. It fits perfectly in there now after cutting it.

I went through this when shopping for the same parts. The issue is that Lemforder isn't providing this part on the aftermarket any longer. They used to...I found a NOS one on eBay a while back, but never found a second one.

So in the end I sprang for the Genuine part.

However the Genuine part is quite a bit more expensive, and I'm not sure how much abuse this part in the suspension sees or what happens if/when it fails. In the end I chose to spring for it. To each their own!

Lesjofers is the OEM. But I could only get them for $70+ through my available sources. I checked the dealer and they were $65.

Couldn't get Lemforder and didn't feel like springing for the MBZ part on something with so little stress.

I just did it because I've felt the difference in other people's cars. I'm glad I did because my old springs were about 2 inches shorter than the new ones.

Personally I've tried to order Lesjofers (OEM) but each time I've done it (I did new springs for the rear on my wagon), the dealer turned out to be noticeably cheaper.
