Good old Jiffy Lube........
I wanted to check the diff's oil level and found the rear diff fill plug completely rounded off.
So going to O'Reillys Auto parts I was told the part is not listed at all. Going to Auto Zone I was told "No Longer Available"
Great.
Had to order from the dealer who does NOT stock one! Good price though.
Now I have to get the damaged one out. The 24 MM head is completely rounded off.
I will heat up the plug and try to grip it with Channel-Loc pliers. If that dose not work I'll try to weld a lever on it to brake it free.
An impact gun was used last time it was checked by Jiffy-Lube and it is frozen in place. Been soaking in Kroil for 24 hours.

I would skip the loc pliers.. I just don't see it coming off at all. If you have the means I would definitely just tack on something to break it loose. I've one another nut route successfully before but I guess you could go ahead and just weld a level in place.

Why don't you go back to Jiffy Lube and make them take it out and pay for the replacement?

Good to watch for.........thanks

I'd be worried they would just screw it up more... (going back to Jiffy Lube..)

I’ve had really good luck getting those off with an air hammer and a strong sharp chisel bit. Works great on both the 24mm head and the 10mm Allen style just go slow. I worked at a salvage yard for years and that was always my first go to.

Iffy Lube! you only have yourself to blame

I mean I've gotten rounded ones off with a chisel and a hammer... if it's that stuck on I'd try the welding trick... but at that point I'd wonder what dumb gorilla used a 1/2" impact to install the plug, did they put the washer back on, and are the threads in the housing damaged?

Chisel and 5 pound hand sledge did not work.
I will have to try the weld trick.

Turns out the plug is some sort of alloy that does not want to take any rod I have.
I drilled out and tried a large Easy-out, that did not work either. I would of though the heat from the failed welds would have loosened the plug, it did not.
I then decided I would drill out the plug and install a 1/2" pipe plug. After drilling the hole for the pipe tap I started to tap the hole in the plug and the plug moved! Not on CW but on CCW to remove chips!
Thank you Jiffy-Lube for wasting 3 hours of my time.
Now I have to flush out any metal chip's and refill the diff.
I could not prove to Jiffy Lube they caused the problem. Its been too long since Elaine took the SUV to them for an oil change. Been going to a local Ford dealer who does not check the diff oils.

I honestly can’t belive anyone trusts knuckle heads working for minimum wage to actually do their jobs correctly. Most fast food workers screw up orders…just think about that for a second.

I did an oil change for a friend, who took her car to Valvoline religiously…the sludge I found said it hadn’t been drained and changed in a LONG time. She was pissed, but that’s what they do.

Sometimes you just have to put your vehicle in the hands of quick lube places like if you're traveling and overdue for an oil change and dealer appointments are a couple of days out. If that happens to me, I generally go to Wally World simply because they are a big corporation and have the money to make a bad situation right plus, they all seem to have an observation area roped off where you come in from the parking lot and before you enter the sales floor. I watch them like a hawk and am not at all shy about shouting out if they are about to do something I don't like (like bring an impact wrench anywhere near an oil change or not use a torque wrench to tighten the drain plug). I've actually had fewer problems with wally world than any of the quick lube places in the fifty-five years I've been driving. I do 75% of my own oil changes and don't really trust the lot jockey at the dealer anymore than I do the "technician" at the quick lube places. Again, just watch them up close and personal. I let me wife take it into wally world one time and she about ***** slapped the technician who tried to put in conventional oil when she had ordered the synthetic - she doesn't take it any more
