Knocking underneath Mercedes C200 Estate, probably coming from the suspension, replaced Stabalizer link both sides only part cured the problem, Suspect it is further back ~middle to rear of car. All arms and links appear ok. Exhaust hangers and exhaust OK

Check control arm bushings or sway links. Could also be strut.

readjust the sensor switch for the position of the boot or lock or replace it.

Check the front suspension for worn or loose componets.

firstly disconnect the track rod ends from suspension and turn each suspension unit on its own to check for tightness ,then lower front suspension onto some stands and try again ,if both sides still move freely then you need a new steering rack as the spool valve inside the rack is faulty

renew the rear springs

check to make sure the strut is good and tight up top. There's 3 nuts there. and i'm assuming it's the original air suspension. if it's been converted could a bad strut itself.

I have a 2002 Escape with +100,000 miles. I've replaced a number of parts in the front end. A simple, annoying rattle is probably the Stabalizer Links. They're probably 10 inches long and cost about $10 each aftermarket. They can be tough to remove.

A clunking, painful rattle or knocking may be a lower control arm bushing. That takes an entire control arm to fix for +$25 aftermarket.

A light squeak when you turn is probably an outer tie rod.

Good luck!

1st starting problem is properly faulty fuel pump 2nd its not the suspension its your shocker absorbers 3rd the air con has an air blockage

hi
check the following
1) Coils (check its resistance and compare it eith the required one in ur manual)
2) Coil Electrical wiring (may be it's corroded, u must check its resistance (check continuty))
3) check if the problem from Ignition computer (ECU)

probably the shock absorber
