I was wondering if anyone knows what this might be? I'm getting a strange squeeling noise, kinda sounds like a bearing. It happens under hard acceleration above about 30mph. I removed all the engine drive belts and drove down the street and it had the same noise. So it is not the alternator, power steering pump or a/c compressor or water pump which was just changed. I replaced the timing belt tensioner and belt. Checked the timing and it was dead on so no harmonic balancer slippage. I put the car on the rack at the shop and ran the auto through the gears and I didn't get any noise at all. I shot penetrating lube all over the center support bearing (which was replaced recently) and the noise was still there when I drove down the road. The car has new wheel bearings, front wheels feel fine. I'm about ready to pull the distributor and check the shaft, however the intermediate pully spun fine when I spun it while replacing the belt and tensioner. The car runs excellent and seems to have good acceleration. Could this be transmision clutch plates? Rear wheel bearings? Maybe it is the center support bearing? Anyone have this problem?
