Old S Replace upper arm small boom engine foot thermostat
1. Over the past two or three months, there has been an obvious creaking in the front of the car on the bumpy road. After cooling down a week ago, it suddenly became serious, and the abnormal noise in the direction was obvious and very harsh.
two。 After the cold car starts, the water temperature is so slow that it takes nearly half an hour to reach 90 degrees.
three. Hold and other red lights, steering wheel and seat can obviously feel the vibration, hanging into the N or P gear disappears.
Diagnosis:
1. The problem of abnormal noise in the front has never been found. I once suspected that the air shock absorber was suddenly serious after cooling. Master Huang in his hometown checked it. When he heard it, he said it was not a shock absorber, but a ball head of a suspension. I said that the sound on the right was obvious. Let me go to the right to the end, and then he turned the steering wheel a little. He put his hand in, and then made sure that it was the ball head of the upper arm, and visually checked that there was no oil leakage. Then a small hole was made on the dustproof cover of the ball head, and some oil was injected into it, but it stopped ringing instantly, and the fault point was determined.
two。 With regard to the problem of water temperature, ML had the experience of changing the thermostat before. I remember that the temperature was below 10 degrees at that time, and it was from three kilometers and seven minutes to 90 degrees after the cold car started. I am sure that this is not normal. The thermostat is aging and closed lax, and I have determined the point of failure.
3. In April last year, I changed the foot of the gearbox, but not the foot of the engine. I felt that the body vibration of the hold was a little big recently. I communicated with brother Ouyang. His S did not shake at all when he was in HOLD. I guess it was the foot of the engine.

Construction:
Last year, the small repair shop of Boss Huang in his hometown solved the problem of wheel hubs. He installed tire pressure monitoring, replaced generators and pumps, and replaced the four empty suspension of the whole car. They all brought their own accessories. Boss Huang personally constructed it very carefully and the price was touching. I invited him to dinner every time I went to his place.
I wanted to do it in Hangzhou some time ago, and I felt that I was going back to my hometown right away, so I’d better save it and fix it with him.
Last year, when I was messing around with Boss Huang, he was forced to dress up by me, WIS, but now it’s more magnificent.
Next, the above picture, there are not many pictures, I am a little help next to, many did not take pictures, excuse me
Go ahead
Remove the tire, then begin to remove the attached line above the air shock absorber, remove the height level sensor on the right, and take down the shock absorber assembly
With regard to horizontal calibration, if you have the opportunity to post again in the future, this Ouyang dude is more professional.
