REAR END NOISE AND SPUTTER

2004 Ford Explorer • 125,000 miles

When I accelerate I hear a grinding noise that sounds like it is coming from the rear drivers side. The truck pushes to the right a little also. Also it sputters/jerks kinda feels like a misfire. Yesterday I changed transmission and transfer case fluid. I also replaced the trans filter. The fluid was at the appropriate level in the rear differential so I did not change it

Scan for codes and check fuel pressure first. Then have your ujoints and wheel bearings checked for the noise.

You might as one may have been stored, but that is why I also said to check fule pressure as it can cause some of your problem.

I have no codes coming up and fuel pressure was good. I went ahead and replaced fuel filter also and have driven for a couple of days. It is still doing it. I had two new tires put on front and balaced all four tires by ford before this post and that is when this started. They did a multipoint inspection also. I had drove the truck home from the dealership (about 20 miles), then to work next morning (about 35-40 miles) then on my way home after work is when I felt a major loss of power. Got home and popped the hood to find my oil cap was missing. I checked oil and it was within the acceptable range barely so I added 1/2 qrt. Then checked oil again and it was at the top of the fill range on dipstick. Contacted ford only for them to tell me they didn't touch the oil cap because they had no reason to pop hood. My response to that was, "How did you check fluid without popping the hood?" "Well we have no reason to remove oil cap so it couldn't have been us." So after about an hour of arguing I said screw yall and went to auto zone and got a new oil cap. Drove better after new oil cap but now I have this problem. I would have thought misfire but like I said it also pull to right when accelerate in addition to the hesitation/stumble.

Check allyour hoses and grommets etc. Then clean the maf and throttle plate on throttle body with choke cleaner. If you have any oles in grommets/hoses replace those also clean tehiac hole in tbody also do you know pressure on fuel? If its' not 30-40 psi then it's not good that will cause rough running and misfires. Check yoru brakes for loose rust as that can cause a grinding noise otherwise have a local pro check it out
