    Default Corolla 2000 annoying grinding noice in slow motion.

    I am tired to find the reason why my newly purchased car is producing annoying noise in motion. Car is corolla 2001 PDM 1.6 auto with 4afe engine. Grinding ( goonj) type of sound comming specially from front wheel side when car hit the road. That particular sound is loud when speed is between 15 - 40 km/hr. Sound is low in high gears. Tried 2 different mechanics and going to workshop since 3 days but no luck. So far mechanic done the following.

    1 - Checked the front wheels, mechanic says one bearing is faulty. to be on safe side i told him to change both the front one. Installed original japanes koyo..RS1300/bearing.

    2 - Excel (goday) was ok. All greased and fitted back.

    3 - Checked rear wheels, one hub was producing little sound, mechanic says grease sy thek ho jaey ga. So he greased it and fit it back with no noice.

    4 - Rear shocks was leaked so it was replaced with kyb shocks. Ride became more stable but grinding sound is still there.

    5 - ATF changed with ZIC ATF. Including opening of gear filter that was cleaned with kerosin oil and fitted back.

    2 - Engine mount checked. 2 was bad. Its rubbers is replaced with new.

    Now everything is fine in suspention but noise is still there. Help!!

    check for the engine mounts / front suspension insulator - jack up the car on all four start the engine and localise the vibration, lately something bad happened in a 1998 corolla 2E huming sound turned to echo and disappear after 2000 rpm, problem was localised to bad water pump

    Engine mount already checked. 2 was bad. Gearbox one and front. Both rubbers replaced with new one. There is no solid vibration with this particulr sound. Its very minor or nere to no vibration. But echo is there. My sound is not associated with any rpm. I also checked it in neutral gear by putting gear in N while driving.

    which area do u live in?

    such diagnosis needs a mechanic with good I.Q
    which is very rare to find

    One mechsnic told me to try different tyres. 185/65/14 with alloys currently installed in my car. Other suspect that sound might be comming from transmission.

    Possibility is of you are facing transmission oil pump grinding sound this is common with these old crap trasmission. So use priper lubrication if not solved then change it its not that expensive but repairs are too expensive.

    Brother i will advice you to go to a tire shop and check the smoothness of your tire as well. Sometimes due to drifting with handbrake tires lost their smoothness and due to bumpy tire it produce such sound as well. its a very annoying and loud sound. You can even check such fault in tire with visual inspection at your own or through some expert tire merchant.

    As Per My Info Those A Series Auto Boxes Are SOLID As OX And Much Robust Than New CVT's....!

    There Must Be Any Ustaadi Done With Box Resulting In Sound Otherwise They Will Last As Long As Your Engine If You Just Change ATF

    Oil Changed Periodically....
