As the new proud owner of a 300TD Station wagon 92 (W124) I am trying to
adjust to feeling of rear wheel drive asf.
My question is: When driving on tarmac and the rear wheel hits a minor
hole or drain in the road, the tail of the car swagger in a quite distinct
(can be right or left wheel it gives the same experience). Is this due to
the build of the car (rear wheel drive and suspension) or an indication
The self leveling has to do with spring... shock is something else unless it
is fully integrated like Caddy... When shock do go bad, you lose control
after hitting a bump... especially in wet weather... and around a turn
hitting a bump.
No, the W123 estates were fitted with rear hydropneumatic suspension
system. The hydraulic struts replace the shock absorbers and springs in
the hydropneumatic suspension system.
Don't believe me? Check out this web site on Mercedes-Benz 6,9 which had
same suspension as W123 estates:
When the system begins to leak, the effect is harsh and bouncy ride as
well as sinking down somewhat. Our 1977 450SEL had that discomforting
behaviour until we replaced the nitrogen gas spheres and recaliberate
the regulators again.
Usually the spheres are the first to go unless the pump fails or the
Do your homework, Tiger, before posting the confusing advices or
comments in the newsgroup.
I can't know about everything... however I was on the track. I did mentioned
that if the shock absorber and self leveling system is integrated together,
then you would have to change that.
Like I said... same deal with Caddy... but Caddy uses air instead of
hydraulic. It is still the same deal... doing the same work as shock
absorber... damping the aftereffect or if you want to get technical,
resonance of hitting a bump.
And again. when shock absorber goes bad in rear... a slight bump in wet
weather while turning will result in tail wagging or if you are going too
fast... an instant spin.
That is common phenonemon with semi-trailing arms due to its unique
design. Worn-out bushings often causes the arm to 'flex' which caused
the wagging behaviour. Caster adjustment is another factor, too.
My father's 1984 BMW 318i had the same problem. We replaced the bushings
and adjusted the casters as well.
Be sure that adjustment is done correctly. It might not solve the
problem the first time. A skillful technician knows what to do.
