Question about 1985 Mercedes-Benz 190

1 Answer

190E rear suspension very ''Soft''

Soft might not be the correct explanation,but i can hardly load the boot,or even three people on the back seat and the back almost on the ground.Should one replace the rear coils,or are there any mods one can do?

They coils are fine, you need to change the shock absorbers. If you are carry heavy loads you can upgrade the shocks to gas shocks. your local mechanic shop will supply these.
hope this helps

I have a Hyundai sonata 2001 2.7cc v6. The back of the car swings when there is heavy load in the boot or the back seat is filled with passengers. I have replaced the back shocks but the problem remai


Shocks were an appropriate step. There must be something else going on with the rear suspension. Sway bar links or bushes would be the next thing to check. Good luck and let us know what you find via comment to your question.

Vid is not your model car but principle is the same.

190e mercedes , where and how to adjust reverse band ,car goes in drive, but wobbles in reverse,


You don't state if it is automatic or manual. For the manual: Looking forwards down the car towards the engine the gear box has three levers on its left hand side. The lever at the rear of the engine is for gear 5 and reverse. From this lever there is a link (metal rod) running back to beneath the gear stick. To adjust this link you need to put the car on a ramp and unclip the link from the gearstick mechanism (three levers side by side). Do not unclip all the links at the same time as it is not obvious which link goes back on which lever!! The clevis on the end of the link can be adjusted by rotating it to either shorten it or lengthen it. There is a locking nut behind the clevis to set the adjustment when completed. Lubricate and clip the link back in place. The 'wobble in reverse' sounds like either a) broken link on the back suspension b) worn subframe bushes c) loose differential mounts (two bushes at the back and one bolt into the subframe on the left/front. If you car is automatic sorry for all this manual stuff, but I would still check out the mechanics of the rear end. Also check out transmission fluid levels, low levels lead to slippage within the torque converter. Another good indication of low fluid is gutless performance coupled with poor fuel economy !!

On a 1989 nissan maxima with sonar suspension II how do you disassemble the strut assembly? the mounting bracket for sonar adapters is in the way of the strut center bolt.


First you must remove the rear seat to gain access to the top strut mounts. The bottom of the rear seat comes out first. On the 91 model there are two tabs at the base of the seat bottm that you pull forward to release the seat bottom. I'm not sure if the 89 is the same. After removal of the rear seat bottom, you will see a bolt at the bottom of each side of the rear seat back that need to be removed. Fold down the arm rest and disconnect the vinyl cover at the base of the armrest to expose and remove two screws. Push up on the rear seat back to unhook three plastic hooks (center and one at each end) at the top of the rear seat back. Remove the seat back. Remove the large metal support panel that is behind the seat back. Safely jack up the rear of the car and support on jack stands so the rear wheels hang free. Doing one strut at a time, remove the two top strut mount bolts leaving the center strut stud nut in place. The strut and mount will lower out of the unibody. Disconnect the bottom strut mount. Remove the strut/coil spring assembly. Using a strut/spring compressor (some auto parts stores rent these) compress the spring. Carefully remove the top strut stud retaining nut, top strut mount, bumpers and strut boot. Carefully install compressed spring, strut boot, bumpers and top strut mount on new strut and install washer and retaining nut. Reinstall strut and etc. in reverse order.

EXPEDITION REAR AIR RIDE PROBLEM


do you have just rear air suspension? here's rear only. 4 wheel different. Deler an run a diagnostic test with WDS machine and get fault codes.
-------------------------------------------------------------------------------------
The air suspension system is designed to improve ride, handling and general vehicle performance for static, on-road and off-road driving conditions:
  • Ride is improved by using an air type spring (the soft ride is inherent).
  • Handling is improved by maintaining constant vehicle attitude.
The system consists of unique rear air springs, the air compressor, air lines, air spring solenoids, height sensor, air suspension control module, attachments and associated signals derived from both driver and road inputs. With these components and signals, the air suspension control module commands changes in vehicle height that are necessary for the load leveling features.
The load leveling feature rear air suspension (RAS) systems shall automatically make adjustments in vehicle height so that the vehicle is always at trim height and constant front-to-rear vehicle attitudes are maintained over the expected load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle's left and right sides for the RAS system shall be restricted to what can be reliably achieved with one air suspension height sensor.
The system uses one air suspension height sensor, a steering sensor, generic electronic module (GEM) and other vehicle sensors to measure driver and road inputs. The system changes vehicle height using an air compressor, two air lines and the use of air springs with air spring solenoids.
The air suspension system holds vehicle height when the rear hatch or any door is opened. The system stores rear vehicle height the moment any open door is detected. The system then maintains this height regardless of the addition or removal of a load. The system will return to its commanded height when all doors are closed or the vehicle speed exceeds 16 km/h (10 mph).
----------------------------------------------------------------------------------------
Air Suspension Height Sensor
One air suspension height sensor is mounted on the vehicle. The air suspension height sensor sends a voltage signal to the air suspension control module. The output ranges from approximately 4.75 volts at minimum height (when the vehicle is low or in full jounce), to 0.25 volts at maximum height (when the vehicle is high or in full rebound). The air suspension height sensor has a useable range of 80 mm (3.2 in) compared to total suspension travel of 200-250 mm (8 to 10 in) at the wheel. Therefore, the air suspension height sensor is mounted to the suspension at a point where full rear suspension travel at the wheel is relative to 80 mm (3.2 in) of travel at the air suspension height sensor. The air suspension height sensor is attached between the No. 5 frame crossmember (upper socket) and the panhard rod (lower socket).
When the air suspension height sensor indicates that the rear of the vehicle is lower than trim under normal driving conditions, the air compressor will turn on and pump compressed air to the air springs. When the sensor indicates that the rear of the vehicle is raised above trim under normal driving conditions, this will cause the air to be vented from the air springs to lower the vehicle back to its trim height level
------------------------------------------------------------------------------
  • Uneven vehicle height
  • Circuitry.
  • Rear pneumatic fault.
  • Air compressor assembly.
  • Air suspension control module.
  • Go To Pinpoint Test I .

When the car is stationary. Push down on the back (Boot or TRunk) as hard as you can a few times & listen for the squeek. It's more common in the rear suspension from my experience. It sounds like the bushings are gone or worn at the top of the suspension struts.
That's if it does squeek. You might not need your suspension replaced just the bushings as they are normally plastic.
Try doing the same by pushing down at the front of the car also as it maybe happening there too.
