anyway ,the other day i was with the mechanic who happened to say that i needed to remove my SLS and replace it with regular suspension system ,to be honest i have been driving this w124/e200/1995 for 2 years ,my father handed it down to me , and since then i have been restoring different parts and so ... anyway back to the subject , the ride feels stiff and bumpy so im going to change them sooner or later.
my question ,if i may ask , how can i be sure that my SLS can not be restored , also what are the benefits of the "regular suspension system" , and how can i know the costs of either fixing the sls or changing it ,what are the best brands of struts ,shock absorber etc to install in my car ,keeping in mind i dont drive it aggressively.
would like to add another point ,he offered to install sachs absorbers ,but told me to ask at other places how much will it cost ,before he do so.
thank you all  |
As a second to dux:
The "stiff and bumpy" ride is almost certainly due to degraded accumulators in the SLS system. The accumulators are a spherical chamber, divided by a flexible diaphragm. On one side of the diaphragm is pressurized gas (nitrogen), and on the other side is the hydraulic oil that fills the leveling strut/ride dampener (aka, "shock absorber"). As the suspension deflects over bumps, oil displaced from the strut deflects the diaphragm against the gas pressure in the accumulator. Over time the gas leaks off, and the compliance of the diaphragm is greatly reduced, resulting in "stiff and bumpy". If the struts themselves are not leaking, replacement of the accumulators is probably all that is required, at rather less expense than new springs and "shocks".
