warped rotors


Asked by Dec 29, 2016 at 08:53 AM about the 2010 Ford F-150 XL

Question type: Maintenance & Repair

2010 F-150 40,000 miles, purchased new.  Don't know how I did it, but the
rotors on the front are warped.  I'm retired and it is not like I do a lot of high
speed driving with 40K miles in 6.5 years.  Since the original motorcraft rotors
warped at about 25K miles, any suggestions on a brand of rotor which may
last longer without mortgaging the house for front rotors

If you recently had the tires rotated they may have over tightened the lug nuts causing the rotors to warp. My 2013 F150 4x4 Ecoboost was returned after the lease was up at 46,000 miles and no issues with the rotors. I did tire rotations myself and used a torque wrench and tightened the lug nuts to the proper torque. I wouldn't be afraid of Motorcraft rotors, but I would make damned sure they kept the pneumatic wrench away from my vehicle and used a torque wrench.

Well then it is my fault. I do a five tire rotation every 5K myself. And if the torque specification is 120 lbs or so, I can assure you my lug wrench tightening far exceeded that. Live and learn. Thanks.

Buy a Craftsman or similar torque wrench and look up the torque spec in the owner's manual. Spend 50 to 100 bucks on the proper tool and it will save you dollars. Also put on the lug nuts dry with no lubrication or anti-seize. Lubrication amplifies the torque applied and only makes things worse. My 2013 had a 150 ft lb torque spec. Not sure if yours is 150 ft lb, but it does say in the manual.

Yep, mine is a 150 lb also. Ohhhhhhhhhhh and I got a torque wrench now, But being 66 it was hard to resist plugging in the compressor and using the pneumatic gun. Never had a problem before with other vehicles, first time pickup truck owner. Thanks.

I use the pneumatic gun to remove the lugs. I turn it way down to zip them on then finish in criss-cross pattern with my torque wrench. Using the proper torque will not usually fix an already warped rotor. Best of luck with it.
