1998 Toyota Tercel 4 cyl Front Wheel Drive Automatic 135000 miles
I have been noticing a rumbling noise on the highway for approx 6 weeks now.I had a flat fixed around the time it started and thought it was a wheel out of balance. Had the wheel rebalanced. Did not help. Tires had 50000 mi on them so I figured they were shot and since my winter tires would be going on soon I figured I would wait. Snow tires went on and still the same faint rumble noise at highway speeds. Noise is more noticable when driving on new pavement on the highway. Mechanic checked front end. It was fine. Checked wheel bearings. They were fine. Rebalanced tires. Replaced one slightly bent rim. Still having problem.I think it is drive train related he says he doubts it. Tranny fluid was drained and refilled every 20000 mi since I have had the car. Just draining the approx 3 quarts that come out when you remove the plug from the pan. It has never had a complete flush. Fluid last changed about 6ooo mi ago(at toyota dealer). Fluid is a nice cherry red but does have a slight burnt smell. Car has to be driving for approx 20 minutes or so on the highway before it starts and is more so on the new pavement. The odd time when the car is warmed up and I am stopped at a light with my foot on the brake the car rumbles/shakes. If you put it in neutral or park it stops. It has been doing this occasionally for 6 years and I had it looked at a couple of times and no one could find anything wrong.
Back to the noise on the highway. If I put in neutral the noise goes away by about 70% but is still faintly there. Seems to be a little noiser when going up a hill. Sounds like when you drive over rumble strips but no where near as loud. There is no vibration in the steering wheel only a very slight vibration at my feet
Any one got any ideas
PS other than slight burnt smell in ATF it shifts smooth and seems fine
have the same problem?
