Its way overdue to change my diff fluid so I went out got 3 quarts of Lucas 80w-90 gear oil.

Got a 24mm 6 point socket..

I go to undo the fill plug first and the thing will not budge, so I get the pb blaster, soak it for a bit, go try it again.. Nothing!!

Im on the street with both feet against my tire pulling the damn rachet and it wont move..
I think the mokeys over at the stealership used a impact gun when they topped up my fluid a few months ago..

Ideas?

Should I just keep soaking it in pb blaster for a few days?

 

give the head a few love taps with a BFH

 

i thought mine was welded. i took a 24" breaker bar and a piece of pipe 4' long, and finally broke it loose. the PO never changed it, it looked like milk.

 

Propane torch and heat it up as hot as you can get it. If that does not work, you can weld a nut onto the plug and the heat of welding plus the added grip on the nut should do it. Otherwise, you can remove the lower studs for the diff and drain the oil there, or if all else fails, remove all the nuts holding the diff in place and then crack it loose and the oil will drain out.

Also, make sure you can get the fill plug out.

 

I will go out, hit it a few times with the BFH, hit it with more pb blaster then give it a shot..

I never want toyota to touch my truck again, this is retarded..

 

Hit it with a torch. then a hammer.

(Wow...three posts at 5:49. What are the odds?)

 

Well I havnt tried the drain plug yet, I wanted to make sure I can fill the diff up before draining the fluid out.

lets hope this works, this is turning into a pain in my a**


only funny thing is every guy who drives by slows down and looks at what im doing

 

that is why i turn wrenches on my vehicles.

 

Alright, went out beat the out of the bolt with the BFH, soaked it with pb blaster and still..nothing!!

I was beating on my ratched to get it to turn, nothing!! the only thing flexing is my rachet.. this is retarded.

I might have to go to my backyard mechanic and get him to heat it with a torch or hit it with his impact gun.

ugh

 

Soak it for a few days with the PB Blaster and the few raps with a hammer may help .

 

get a breaker bar and a big cheater bar. If all else fails you could always take off the breather and fill it up from there

 

I feel for ya. I went through that exercise last year and the only thing that worked for me was an air chisel to loosen the fill plug. If you do this, plan on buying a new plug. They are not expensive. Hope this works.

 

I had the same problem. Here is what I did, you will need an air hammer with a flat chisel tip. make a score approx 1/8'' on the edge Take the air hammer and bust it loose ccw. hope this helps.

 

My fill plug was like that last time.

I welded a long piece of flat to it - like a welded on cheater. Damn thing was so tight it broke the welds the first time...

Would antiseize be a good idea on these, or would it contaminate the gear oil?

 

had to use a breaker bar on mine.

stop 'em and ask if they want to help!

 

Other option not mentioned so far is vice-grips. Part of the problem is the damn thing is so thin it's hard to get any torque on it with a socket - just wants to twist off. You might even have better luck with an end wrench since the force will be more in line with the plug.

 

Well I will go try again, I will beat on it, soak it and try again..

If not im gonna wait till I can get my hands on an impact gun.

 

Get a 12 point socket with a 4 foot breaker part. The 12 point the work alot better. I had the same problem with a 6 point socket.

 

Everyone said to get a 6 point as the 12points can round off the bolt head.

 

personally I would go with the six-point- it just makes more sense. But- If i was tugging on it for hours I would try the 12-pt. If it slips, just stop immediately. Shouldn't damage it to where its not removable. I would say hit it with a torch, keep it on there a long time. Then throw water on it. Should come out after that.
