My 2013 f350 SRW with 14k on it makes a scraping noise from the front end whenever i go over a bump. It will only do in in certain situations such as turning onto a side road with a downhill grade. It sounds like a shock housing or bushing. I have had it into the dealer four times for the condition and they can not find a problem. It has done it since day one. If i turn the traction lock off it will not do it. I am thinking maybe a wheel sensor? It has not set any codes. Has anyone else experienced this?

 

Hi elishaman,

When you were at the dealer for this, did you take your tech on a test drive so you can replicate it for them? If not, I recommend that as a next step. You may also want to get a second opinion at a different Ford Dealership. Enter your ZIP code here to find some options: Ford Dealers | Locate a Ford Dealer Near You | Ford.com If you'd like, I can loop in your regional customer service manager. Just PM me your full name, best daytime phone number, VIN, current mileage, and servicing dealership. I'll get this into their hands.

"If i turn the traction lock off".......... Do you mean traction control or differential lock? Do you have the electronic locking rear differential? If so, is it engaged when you hear the noise? If yes this is normal. Turn it off. You only need it when your stuck or driving in deep snow at low speeds. It will automatically disengage at 25 or 30 mph then re-engage again below that speed.
