I have a 98 F-150 and i just rotated my tires recently, and soon aftere that I started to hear this chattering comnig from the back right wheel. I only does it at slow speeds or when i go over bumps. I thought it was my center hub cap but it is plastic and it sounds like metal clanking together.
My truck has a 7.5 fabtech lift on it but I dont think that has an affect on it. Im not sure if its my drum brakes or my axel. so if any one has this same problem please let me know what you did to pix it.

Thanks

 

Hello copyminkey and Welcome to FTE!

I would check the rear shock at the wheel. A worn bushing on a shock can make a ton of noise. You could also check the lugs on the wheel to make sure everything is tight. I really doubt it's your brakes or the axle.
