View Full Version : Are 500E shocks the same as 1994 E420?

Please tell me, shocks on my 500e broke, rear one, please tell me if I can put 420 shocks on it

my impression is if the 420 has SLS (automatic ride height) then they'd be compatible.

I'm thinking you should rebody an E63 with the 124.036 body. That would solve your engine, transmission and shock problems! :D kidding, seriously only kidding.

The W124 E420 did not have SLS offered in USA. Standard shocks are not compatible, the 500E has hydraulic rear shocks.

You'll need a 500E rear shock. Check with David Hendy or fredtga, they both have used rear 500E shocks for sale. Nothing else is equivalent, you need either a new one, or a used 500E rear shock.

How did it break? I've never heard of one breaking before... even leaks are pretty rare.

I just got the car and when I drive it it jumps like crazy what could be the problem then?

Could you define "jumps like crazy"...? Do you mean the rear feels rock hard and rides very rough?

If so, that usually means failed nitrogen spheres, not failed shocks.

I wonder if these would work: http://www.benzworld.org/forums/sale-wanted-trade-giveaway/1712419-w210-wagon-rear-sls-shocks.html

Still, sounds like in reading between the lines it might be accumulator(s).

Wagon SLS struts use a different mounting system and won't work in the sedans.

I think guy mean that it is jumpy suspension, the same when shocks/struts are gone on the regular cars.

Car becomes not stable and you can push on the body up and down easily ...

Guys sorry so what can be the problem?

When I drive on the bumps the rear of the car jumping like a ball

The E500 uses hydraulic struts in the rear, NOT shocks. The nitrogen SLS spheres located in the spare tire area in the trunk, are the "shocks" that dampen bumps and rebounds. If one or both of these are bad, they car will feel extremely harsh and rubbery. You will be bouncing up and down in your seat when you go over speed bumps and also down the road.

There is a simple test to see whether accumulators (spheres) are bad. Press down firmly and rapidly on a rear corner of the bumper. The car should go down a couple of inches in a firm, smooth, damping motion. It should bounce once slightly and then return to rest.

A bad accumulator will not go down in a smooth manner, if hardly depress at all. It will feel very firm, rubbery with little to no smooth up and down motion.

You have to use the specific SLS struts + accumulator combination to achieve the dampening effect, unless you remove the system (which has been discussed here as well). Removing SLS is not advisable. Replacing the accumulators is a fairly easy and common job to do. Replacing the struts is not difficult but they are quite expensive. Lucikly the struts don't fail very often, and much of the time you will see hydraulic fluid leaking externally on them when they are failing (sometimes fluid leaks internally too).

I was thinking also dropping the car, should I? Ad if I do it , how much? I got 18" monoblock 2 on my car now.
Which brand should I go for ?

Привет, ты мог бы мне объяснить на русском в чём проблема, машина как попрыгунчик сзади?
зарание спасибо

I had this problem several days ago.

Changed the aircells/accumulators 1403280515 (two balls behind) and everything works smoothly now

Hope this helps
