mbpauly Posted July 1, 2017 Share Posted July 1, 2017 I have an odd noise coming from the rear passenger and I thing occasionally from the rear driver ONLY when accelerating AND turning at the same time. Especially from a stop or uphill. It does not seem to happen UNLESS I'm making a 90 degree turn or greater. It does not happen every time which is frustrating to try to replicate for my mechanic. The sound is not rubbing and does not sound like metal on metal. It has a LOW vibration tone to it. Not clunking..... It sounds and feels like the wheel in question is having a brake applied to it or the opposite as in trying to spin but it is being held back. the sound is kinda like the noise your lips would need to make in a musical horn mouth piece. The brbrbrbrbrbrbrbrbrbr sound but not very loud. It is felt but subtly. Sorry for that description but its the best I could do. ANY help would be great to direct myself or my mechanic would be greatly appreciated. I should also note that the only other issue is a slight wobble at 65 - 70, I have only owned the car for a month, I don't know any history or maintenance, and it has 58K miles on it.

1 Lucky Texan Posted July 1, 2017 Share Posted July 1, 2017 automatic? you could try using the FWD fuse under the hood. check you manual for spare tire use. are all 4 tires the same? (model/brand and size?) Quote Link to comment Share on other sites More sharing options...
mbpauly Posted July 2, 2017 Author Share Posted July 2, 2017 (edited) Yup, its an automatic with the cvt. Not sure about the whole FWD fuse thing as I'm not seeing anything labeled as AWD or FWD on either cover. UPDATE: I researched that a bit and it appears that the AWD fuse bypass was not done in my year. Manual states to simple put back tire on front and spare on back only. All four tires are the same and appear to have even wear. Additionally the spare appears to be unused leading me to believe that my issue was not caused by over use of the spare.

1 Lucky Texan Posted July 3, 2017 Share Posted July 3, 2017 can you perform slow (idle or just above) tight circles on dry pavement with no noise or bucking/jerking? Quote Link to comment Share on other sites More sharing options...
mbpauly Posted July 3, 2017 Author Share Posted July 3, 2017 yup, no problems with that. Primarily happens when accelerating up a hill AND turning. Or accelerating a bit harder than normal AND turning. And again, it needs to be a fairly sharpe turn for it to happen. No jerking or bucking occurs. just a soft vibration and medium level noise.

1 Lucky Texan Posted July 10, 2017 Share Posted July 10, 2017 u-joint? the driveshaft turns much faster than the axle so, sound and rumbling could occur quite fast - does it seem like the vibration is 'about' 4 times faster the the wheels are turning?

mbpauly Posted July 14, 2017 Author Share Posted July 14, 2017 No, it sounds more like rubbing. Although I'm confident that nothing is rubbing. if feels and sounds like the rear tire is being braked on the turn while accelerating and the sound matches that as well. I keep thinking its an AWD problem in that the power is being improperly distributed or something. Quote Link to comment Share on other sites More sharing options...
brus brother Posted July 14, 2017 Share Posted July 14, 2017 (edited) well if it sounds like a duck, and walks like a duck... why not pull the wheel and check to make sure that the brake caliper or pad isn't getting locked up. Lubricate all points and make sure the pads float nicely. I had a set of aftermarket pads where the "ears" were so heavily coated with paint that they got hung up. also check to make sure the dust shield hasn't been bent. Does it change the symptom if you try braking under the turning/accelerating condition? Edited July 14, 2017 by brus brother 1 Quote Link to comment Share on other sites More sharing options...
