2003 ford explorer 4.0
hi,I've been browsing thru the forums and love the help and advice,howerver i'm having a new problem.
my 2003 ford explorer xlt 4.0 v6 114,000 miles just developed a problem
the rear end just started making a sound everytime i accelerate i hear like a grinding sound it starts at about 45mph and then is quiet at 60mph.
it sounds like: whom,whom,whom,whom,whom.
I lifted her up on a lift and the rear driver side cv axle was spewing grease all over the inner rim.....so I replaced that axle along with bearing,hub and both rear pads and rotors.
took her out for a ride and still the same thing.
now I lifted it up again and had my wife step on the gas and i noticed that the driver rear wheel locks up while all the other 3 keep on spinning also i hear a noise by the driveshaft (rear) and when inspecting that area its all dry and the shaft is all rusty and pitted looking.however it does not move when checking for u-joint play,so i ruled that out what has me still stumped is why that rear driver wheel locks up even with a new cv axle.went to ask a mechanic friend and he told me to replace the new axle (that was bought at autozone) also when highway driving at 50mph i shifted into neutral to see if i still hear the scraping/grinding and it seems to get lower like its almost gone while letting it just coast i rev the engine to see if it returns and nothing i put it back in drive and as soon as i touch the gas pedal there goes that friggin rubbing sound again. i dont know if both are issues are related i'm stuck scratching my head..I checked rear diff fluid and it was good but decided it was time for a change anyway so i swapped it out with some mobile 1 synthentic 140 and friction modifier and still the same friggin noise.
if any one can please chime in and help me out I would greatly appreciate it.
i'm ordering a new axle from dearborne axle.but hoping someone might catch something that i am missing.thank you all
 






Maybe its the tranny, pull the pan and check for debris. A failing planet inside the transmission will make noises in different gears.
 






thanks for the advice..
I just did the solenoid block,filter and fluid,it had no shavings a month ago.
just to keep everyone posted I finally found the problem.
put it back up on a lift and it is my rear carrier grinding opened it up again and found no shavings in diff fluid.
went to my brothers and removed the 355 from hi totalled 03 and will install this weekend.will try to put up picks of the job when done and let every one know if all is ok.
