I would check that the wheels are balanced, and the CV joints first.
Thanks. Got the wheels balanced, still hear the noise. Will get CV joints checked next!I would check that the wheels are balanced, and the CV joints first.
Thanks. If throttle was the problem, do you think it explains the humming noise between 40-60 mph before transmission fluid change, and then between 55-65mph after transmission fluid change?How about a good throttle body service?
Well, I wasn't going to say anything. However, since you have now mentioned it twice.then between 55-65mph after transmission fluid change?
Thank you! I’ll look at those things you mentioned.Well, I wasn't going to say anything. However, since you have now mentioned it twice.
If your observation is correct the new fluid hasn't fixed anything, just masked the issue for now.
But, I'm thinking that is just coincidence. Road surface differences, ambient temperature, and a dozen more variables can effect vibrations. Your issue is almost guaranteed CV, wheel bearing, wheel balance, or suspension related.
