I'm not a mechanic, but check to see if there's a recall for your rear suspension toe-links. I just got one this week for my 2014 Explorer Limited, and so did another Explorer owner. Check it out to see if your vehicle is covered in this recall and if this may solve your problem (recalls are free and cover original owners and subsequent owners- they may just not have your name and address to get in touch with you) call your Ford dealer even if you didn't buy your vehicle there and give them your VIN# and they can look it up for youJust bought a 2014 base. It has. A loud creaking coming from the rear end. Service department says it’s a bushing but can’t replace just the bushing, have to replace the complete assembly. Is this true? They have tried lubricant and Ir doesn’t help.
