Hi Guys!!
Hang in there reading till the end, I try to give as much details
... I have a W221 S550 - 2011 model imported from Japan with low mileage. When the car was just bought, vibrations were felt in the steering wheel, even the brake pedal, although I don't know what to expect (because of driving a 2017 BMW 5 series) in terms of what's normal/acceptable and what is not.
So I had do the following items done (Some might not be relevant but I mention them):
- Wheel balancing & alignment, and re-torqued Lower, upper arm and suspension bolts and relubricated
- Replaced suspension Valves
- Changed all four wheels and had all rims checked and were ok. New Tyres fitted were continentals (2021).
Then went out driving the car, I realized the vibration was gone. Then next day it was back, so I rush for wheel balancing at another place, done and no vibration out of there, then it comes back next day!
I took the car later to Continental themselves to inspect the tires, they informed me that the tires were in perfect condition, and they re-balanced them and I went for a test drive which was satisfactory, but the vibration came back same night.
so later I took the car and changed:
- All brake pads, both front brake disks
- Ball joints
- Control Arm Assembly front
- Lower & Upper Arm Assemblies
- Steering Rack end RHS
- Stabilizer Link Rod.
The crackling sounds from bushings were gone, steering vibration gone, then a while later it came back in a strange matter.
I start the car in the morning and drive a distance of 125km to work, vibration exists starting from 90kmh till 125 kmh then after a while driving it goes away. 8 hours later, I start the car and drive back home with no vibration at all.
Next day, I start the car same time in the morning and drive to work with no vibration at all, 8 hours later I start the car to drive back and the vibration is back on the steering for a while then disappears.
Nowadays, I just start the car, and when I accelerate in a fast manner to 100kmh nothing happens, a bit of firm braking and accelerate normally to 100 and steering vibrates..
I guess it cannot get any weirder than this, I am still trying to troubleshoot! Any ideas??
regards,
M
