Buster1 Posted January 4, 2016 Share Posted January 4, 2016 84k miles on a 2010 FFH, and I have been noticing some "wheel hum." It changes with speed and seems to be more noticeable when slower. I had the tires changed as they were all original and I thought that the hum was maybe from the old and worn tires, but it still seems to have a hum. Wondering if anyone else has had bearings replaced, or found the cause...and what was the cost? 0 Quote Link to comment Share on other sites More sharing options...
Allamand Posted January 4, 2016 Share Posted January 4, 2016 Possibly the wheel bearing going..mine went on the drivers front. It even started making noise when I turned sharp. 0 Quote Link to comment Share on other sites More sharing options...
Milan_OH Posted January 4, 2016 Share Posted January 4, 2016 My right front went @ 67,500, cost $341 at an indy. Have 103K now, drivers side is still good. 0 Quote Link to comment Share on other sites More sharing options...
Buster1 Posted January 5, 2016 Author Share Posted January 5, 2016 What kind of noises did it make? Mine is hard to describe, but is sort of a whirring that changes directly with speed. 0 Quote Link to comment Share on other sites More sharing options...
Milan_OH Posted January 5, 2016 Share Posted January 5, 2016 Yes, dull hum, whirl or whatever. One test is to listen when you turn the wheel whilst driving. You'll hear the 'pitch' change when stress on the bearing changes as you move the wheel back and forth. 0 Quote Link to comment Share on other sites More sharing options...
Buster1 Posted January 10, 2016 Author Share Posted January 10, 2016 Just dropped her off at the dealer. I'll post soon with what they find, a course of action and the cost. 0 Quote Link to comment Share on other sites More sharing options...
Bogy Posted January 11, 2016 Share Posted January 11, 2016 I have a 2006, with 196,000+ miles, and I've had to have 2 bearings replaced. I'm going to bet that's what it is. I also thought it was tire noise the first time. The second time I know what it was. 0 Quote Link to comment Share on other sites More sharing options...
Buster1 Posted January 12, 2016 Author Share Posted January 12, 2016 UPDATE: Well I am shocked. The dealer just called and my bearings are okay, no issues. It turns out that my differential is bad! I have no clue how that can be, but that is what they are telling me. Luckily the FFH has a 6yr/100,000mi powertrain warranty and the service guy said I am covered. Whew! He said this it pretty rare for the FFH and "thinks" its related to where the electric motor inputs power to the drivetrain. Apparently they have to pull the entire motor and transmission and will be swapping in a new transmission and differential. More to follow. 0 Quote Link to comment Share on other sites More sharing options...
lolder Posted January 12, 2016 Share Posted January 12, 2016 The hybrid warranty including the transmission is 8 years and 100,000 miles. 0 Quote Link to comment Share on other sites More sharing options...
Buster1 Posted January 13, 2016 Author Share Posted January 13, 2016 correct. I misspoke. It is 8/100,000. and a second call to Ford today reassured us that we will be fully covered for the full engine and tranny pull and replacement of parts. 0 Quote Link to comment Share on other sites More sharing options...
Milan_OH Posted January 13, 2016 Share Posted January 13, 2016 bad differential, pulling motor, new tranny.....wow, my MMH just turned 103K, if my differential goes out, I'll be totaling out the vehicle. That repair must cost ~$5K?? Let us know. 0 Quote Link to comment Share on other sites More sharing options...
Buster1 Posted January 14, 2016 Author Share Posted January 14, 2016 This is unreal. Now the dealer is saying the Ford "expert"came out to have a look before pulling the trans and engine and he thinks it COULD be bearing related! They are going to check (and replace if necessary) the wheel bearings! If that doesn't solve it, then they will pull the engine and trans. Un-real. I think it's a bad case of mis-diagnosis by the local shop. I'll keep you posted. 0 Quote Link to comment Share on other sites More sharing options...
lolder Posted January 14, 2016 Share Posted January 14, 2016 We've not heard of any transmission failures in the 2010-12 Ford hybrids so this would have been a first to my knowledge. Let's hope it will be a wheel bearing but you'll probably have to pay for that. The 2013+ have had some early transmission failures and maybe that's what confused them. The early ones were built by Aisin, the "Borg Warner" of Japan. The 2013+ were built by Ford and they got some things wrong. 0 Quote Link to comment Share on other sites More sharing options...
Buster1 Posted January 17, 2016 Author Share Posted January 17, 2016 It appears to be the front wheel bearings. They argued with the Ford tech guy and in the end it was just bearings. I drove the car around today and it seems just fine...and no more front end noise. Guess the tech guy was correct, and maybe my dealership learned a thing or two about diagnosing problems. I'll keep a close ear on it, but so far, she seems quiet and solid again. 0 Quote Link to comment Share on other sites More sharing options...

drolds1 Posted January 17, 2016 Share Posted January 17, 2016 (edited) Just, wow! They were going to replace your differential? Unbelievable! I wonder if Ford would have denied that warranty claim and the dealer would have been on the hook for all the unnecessary parts and labor. I guess you don't need to be told to stay away from that dealer. Edited January 17, 2016 by drolds1 0 Quote Link to comment Share on other sites More sharing options...
lolder Posted January 17, 2016 Share Posted January 17, 2016 There were very few transmission failures in the Gen I & II Ford hybrids so dealers were probably unfamiliar with them. There were quite a few in Gen III ( 2013+ ) Ford hybrids. Wheel hums are a pretty routine bad bearing diagnosis. Long live Tesla's no dealer model ! 0 Quote Link to comment Share on other sites More sharing options...

That's what I was thinking when I first read this thread and I don't even own a Hybrid. Just from observing. 0 Quote Link to comment Share on other sites More sharing options...

Buster1 Posted January 24, 2016 Author Share Posted January 24, 2016 They wanted to charge me and estimated $1k before the work began. According to them "to troubleshoot and rule out the bearings." We told them NO WAY we're they going to replace parts and charge us just to isolate the problem. If the bearings were bad, we would pay for them, but if they were fine and the trans was truely at fault, then the bearing replacement would be on them. They found 2 bad bearings (right wheel and a center axle bearing?) and they were able to work with us on parts and labor. I think it ended up being $800 out the door...which is par I suppose for 2 bearings and labor based on my research. It's been 2 weeks now, and she is running great and quiet too! 0 Quote Link to comment Share on other sites More sharing options...
SeekingFF Posted February 23, 2016 Share Posted February 23, 2016 (edited) My right front went @ 67,500, cost $341 at an indy. Have 103K now, drivers side is still good. Wow that's early for a differential to go. Wish Ford would stick with making GOOD ENGINEERED cars that last and skip the electronic nonsense that is likely to fail and be costly to fix. Is it hard to get the extended warranty after you bought the car? I still have over a year left on the current warranty.

akirby Posted February 23, 2016 Share Posted February 23, 2016 If Ford skipped all the "electronic nonsense" they wouldn't be selling many vehicles. BTW, how does a mechanical wheel bearing qualify as "electronic nonsense"? 0 Quote Link to comment Share on other sites More sharing options...

BTW, how does a mechanical wheel bearing qualify as "electronic nonsense"? They'd sell them to people that realize too many extras means more things to fail. A mechanical wheel bearing does not qualify as electronic, however, if they maintained focus on ensuring good engineering on mechanical things instead focusing on frivolous electronic things then those mechanical things would last longer and there would be less to fail Edited February 23, 2016 by SeekingFF 0 Quote Link to comment Share on other sites More sharing options...
lolder Posted February 23, 2016 Share Posted February 23, 2016 A wheel bearing is not a "differential" but that's still early for a wheel bearing to go bad. 0 Quote Link to comment Share on other sites More sharing options...
Milan_OH Posted February 23, 2016 Share Posted February 23, 2016 A wheel bearing is not a "differential" but that's still early for a wheel bearing to go bad. My '10 MMH has been extremely reliable. The only maintenance having been; (1) wheel bearing (1) rear brake job (1) tail lamp failure and a couple CELs which correct themselves after a few days. I've never had the vehicle back to the dealer for any updates (by choice). Original front brakes....really, 106K? I set of tires. Now, please excuse me while I find some wood to knock on. 0 Quote Link to comment Share on other sites More sharing options...
