MINI F56 Replacement of PowerFlex bushings completely solves abnormal sound in lower limbs and arms
LeonaJessie 
9 First of all, let’s talk about the problem of the lower arm of the F56. There are all kinds of complaints and noises made by riders. This is a design defect. This sound is heard all over the world. Let’s first take a look at the complaints of domestic riders:
Second, talk about the condition of this car, it doesn’t ring when you listen carefully, it rings from time to time when you pass the speed reducer, and you don’t pay much attention to it. You mentioned this question when you went to the 4th son for maintenance. After the maintenance, the 4th son said that there was nothing wrong with the inspection. Everything is fine. Then I went on to look for the noise, and I found the rule. After the cold car was started, the probability of making abnormal noise at low speed over the deceleration belt was relatively high, and I had recorded a small video of the noise.
The crisp metal crash in the 5th and 11th seconds! I didn’t know it was the lower limb arm problem before, but I thought it was a shock absorber problem!
The crisp metal crash of the 7th and 13th seconds!
When I was maintaining again, I went to the fourth son’s shop with a small video, and the fourth son also watched the small video. I just couldn’t make this sound when I went out for a test drive. finally, I replied that I had no problem and let me wait for a bang before I came back to fix it. Not reconciled to continue to soak in the forum mixed car friends, saw that some riders went to the 4S store to change the next arm to eliminate the abnormal noise, at this time my car has been insured, the fourth son shop is also disappointed. I went to the repair shop to replace the lower right arm of a car dismantling part, and the sound was still the same after the change, but there was no solution. Once I drove to a cold place to play, Huize Daicaoshan Ski Resort, the car stayed outside at a temperature of about 0 degrees for several hours, ringing all the way down the hill, and the road was a little bumpy. It stopped ringing after getting off the roller coaster. In addition, the frequency of abnormal noise is also much lower when it is very hot in summer, and the speed reducer stops after the cold car has been started. Finally, it is concluded that the sound is related to the temperature, cold is easy to ring, heat is not loud.

Then, went to a number of friends opened the repair shop, shock absorbers, plane bearings all kinds of disassembly and inspection, there is no problem, it is impossible to find out the reason, the master also has no way. I’m still not reconciled to it. I won’t give up until the problem is solved. When there is nothing to start searching foreign mini posts, an accidental search on FB found a bmw technician’s home page, he provided a suspension upgrade scheme, the front arm replaced with PowerFlex bushing can eliminate the abnormal noise of the vehicle over the speed bump or potholed road.
Inquire decisively what PowerFlex is. It turned out to be a better rubber piece than the original factory. The omnipotent horse father store can also be bought in China.
At this time, a rider has changed into the PoweFlex bushing, but he changed the shock absorber and thought it was too hard, so I took over decisively. I bought the bushing and gave me the lower arm to avoid the process of installing the bushing. The lower arm with reinforced bushing is loaded immediately after hand, and the test drive is installed. It has a different effect. It is much more comfortable than that of the original factory, the direction is more compact, the control is more precise, which means where to hit, and the damping effect of the speed reducer is also leveraged, unlike the hard bumper of the original car. After the change, the strange noise completely disappeared, like a new life, driving a new car! After changing the lower arm, it is essential to make a four-wheel positioning!
Open it! Open it!
Keep opening it!
The protagonist appeared on the stage, and the lower limb arms transferred by cyclists with reinforced PoweFlex bushings did not look clean!
The purple and black rubber parts on the arms of the lower limbs are the key to improving the abnormal noise.
Apply lubricating oil where metal and rubber come into contact
The lubricating oil must be applied, otherwise the squeezing sound of the forced rubber is a little loud! I took a detour before, and it took two times to disassemble and assemble it!
After loading, do a four-wheel positioning.
Go home for nothing
The purple PoweFlex bushing stands out.
After regaining a new life, you have to change your look, and the whole car will be blackened: black roof, black nose, black bright strip. (JCW a touch of red net, black net frame, black ear, black light frame, black oil tank lid has been changed before)! And then change to a silver flower, no flower, no mini!
Change the white top to the black top
Black nose
Black bright strip
JCW side pull flower
JCW model front machine cover pull flower
Violent bear skylight sticker
The great task has been completed!
Riders who have the same problem can refer to it, not only solve the abnormal noise but also improve the control! Please help the master set up the essence!
