[C Perera]

Dear Friends, I have a N16 Auto Car. Now there is a sound "Hmmmmmmm" from Razors ( i think so). Do i have to replace those? If so, what it will be the cost ?

Its easy to figure out if its the bearings. If its from the engine mechanics use a scope like device to listen to the hum and pin point where its coming from.

you might wanna do a bit more explaining on this matter.... if its the bearings can be done for about 3k

If the sound comes from wheels its possibly the hub razors. you can check this easily. Jack up the car, rotate the wheels. If they do not rotate smoothly possibly hub razors are gone. Modern hub razors come as a compact set with 4/5 screws. .

I did a hub razor replacement 2 years ago. It was about Rs.2000 per wheel. If the intensity of humm varies with the speed, this could be a probable hub case.

it could be as simple as badly worn out tire or tires. best is to isolate which tire has the noise and check with a different tire (i.e spare wheel ) to see whethe the noise disappears. Then you can get into other diagnosis such as checking hub bearings. Most probably this should be from rear wheels.
