I recently bought a Corolla AT [ done 102,000 kms] that seems to drive noiseles and vibrationless except when the a/c is on at low speeds [ 0-5 Km/hr speeds] when the vibration and noise is quite pronounced, and this noise and vibration both build up for a while and then subside. At the height of the buildup, the vibration is quite high. This is quite pronounced in D mode. In N, one can still feel the vibration but is lesser. The Toyota workshop suggested changing the engine mounting, and they have changed a part called "Insulation, Eng Mounting, Fr" - however, this hasnt solved the problem at all. I checked with a third party mechanic and he suggested the problem still lies with the engine mount.
My questions are two fold
1. Is the part changed by the toyota workshop the complete engine mounting, or a part of it? If its only sub-part of the mount system, should I go ahead and change the entire mounting?
2. Is the problem related to the a/c system instead? Should I get the a/c clutch, compressor etc checked instead?
3. I also read on this website that this problem could be related to engine harmonic balancer or the AT Flex plate - should I check these too?
Thanks a ton! I am so irritated with this problem, that I am thinking of selling the car, which I really cant afford to right now. Hence, your help to identify the problem will be really appreciated:)
have the same problem?
