Your car was lowered by someone who didn't know what they were doing.
When these are lowered you need to remove part of the bump stop on the shock itself, if not you hit a bump, which mashes up the bump stop, which is the chewed up piece around the shaft in your picture.
Also, on genuine shocks they have an internal bump stop so when the wheel leaves the ground the shock isn't transmitted through the body of the shock itself.
You need to remove the shock, fit some standard shock bump stops and then cut one of the 3 rubber sections away.
Absolutely lovely 500E...looks the cats knackers !
You referred me to this link....i think Dave (Uberwagon) has given you best advice already.
My black 500E is lowered as aggresively as can be - H&R with 1 nib spring cups, probably sitting almost 1/2 inch lower than yours ! I am running adjustable Koni shocks which are absolutely superb. They work perfectly with the H&Rs.
No reason you cannot run your stock 500e shockers with this set-up, but as Dave set, you need to cut one section of the bump stop off. AMG did this on their system designed for the w124 E60. The shocks were the same length as the stock item, i had a full set but sold it.
Another shock you can rely on to do well with this set-up is the Sachs item, labeled 'Super-sport', fitted standard item to al 190E 2.3-16s.
I think the starting point would be to renew both the upper mounts (3 bolts hold this onto the frame at the top of the strut in the engine bay)...these upper mounts are crucial for correct functionality of the shocks. i would then replace both the wood look stop pieces but cut one section off as Dave highlighted, replace both rubber boots and ideally a set of Koni adjustables should provide perfect setup.
Those inner front suspension bushes look past their best and was the car lowered before the tyres wore the inner shoulder out, do you have any reference to the camber setting.?
Also make sure that the place you had your tyres fitted can balance the wheel correctly. It took a couple of places till mine were properly balanced and I still don't know why this was an issue.
Car really does look nice
Clearly alot of work done on the car.
Before splashing out further dollars and given the symptoms you describe, i'd run one test, if you haven't already.
Fit a set of stock MB 16" or 17" 1-piece wheels and tyres and see if that carries the same issue. In many instances, such symptoms can arise due to wheels not being 'true' and when dealing with multi-piece wheels like the Brab ones on yours, the issue can be magnified. What balancing weights are there on the front wheels...if there are alot adding up to over 30g, then the wheel maybe warped/untrue.
I don't see that this issue is related to ride height. The tyre wear is likely a result of bad camber/castor alignment. My black 500E is lowered more than yours and doesn't have the tyre wear issues that many think must occur with low ride height.
You can raise your car without changing the springs, simply fit thicker spring pads, they come in 1 nib to 4 nib on the w124. 3 nib might be the best bet if you want to carry some margin, although 2 nib pads will raise the car materially. I think the car looks nicely poised, and changing ride height is unlikely to resolve the issue.
A couple of items that can make a substantial difference :
- rear torque arms
- roll bar bushes (front and rear)
But my first suggestion would be to drive the car with simple stock wheels. I have a set that i know are true, if you wish to borrow, you are welcome anytime.
