I have a 1995 Toyota Corolla and the front wheel (driver side) is making a grinding/humming sound when I’m driving. The sound is loudest when driving on the freeway (when going 75mph it gets up to 93 db… used a smart-phone app to detect level of noise). When driving in the city you can’t really notice the noise unless you are going faster than 30 mph. I took it to my mechanic and he can’t find the problem. Here is what he has done:
He checked the front Axles (no play and no tear in the boot).
Checked the bearing and no play
Brakes were bad so he replaced the pads (nothing).
Moved the front tires to back (sound is still coming from the front)
Changed the struts (they were worn, still same sound).
He took the car off the ground and “drove it” I did not hear the sound then (but then the tires were not spinning very fast).
He said the mounts look OK.
The noise seems the same level if I go straight or if I’m turning. A few weeks ago the noise was present but not as loud as today (I took the car on a road trip and it seems that it got loader after that).
My mechanic says it *could* be the beginning of a tranny problem … but if I drive straight and then put the gear in neutral I still hear the noise (not even a change in noise level). Do you have any idea what’s going on?
have the same problem?
