Good Info super knowledgeable thanks for the video

Great 14MM socket, I’m having an issue with my Wife’s 2007 RAV4. Thanks for the explanation of hove the valve works. Liked and subscribed!👍

[@Beridan63]

Well done.... on my way to the Toyota dealership to pick that part up today.

[@MrStephen777]

That;s really usefull information, as myne is leaking . was going to replace bearing and seal, however it is not leaking all the time ; just did it after long journey. So will get new Valve and see how it goes.

[@davescheer5038]

Yea , I got a 2002 4 runner 2 wd with a leaking passenger side axle seal , I’m off to get a valve to replace my old one , I haven’t checked the fluid in the differential yet as I just bought the vehicle a couple of days ago, but have bought fluid already , I’ll change it to , the vehicle needs the maintenance check list , valve cover gaskets ( slow leak ) , timing belt ( last replaced at 67,000 from sticker on cover ) will do a replacement, along with tensioner bearings , I’ll replace water pump and belts , and it’s got 187000 miles on it so I’ll replace the radiator just to be safe and hoses to , and maybe a tune up , she runs smooth but I just want to keep it in-good condition , it didn’t have any maintenance paperwork when I bought it I did an oil and filter change already , it’s in good condition it had Disney stickers on the back window and coffee stains on the rear seat floor , I’m guessing it was moms car and had a lot of highway miles , so far I’m lov’n this vehicle ! 👍🏼 Thanks for posting! 2/24/22.

Yes mine was clogged solid. It sounded like opening a soda bottle when I took it out.. I extended my breather to behind the rear blinker incase I cross high water.

[@dalephillips8250]

This is what I'm doing on my Tundra today.

[@dennisharvey9894]

Thanks for the video! I noticed I had a similar problem except mine was leaking at the axle side of the vent hose. Hose seems to be connected well so I’m guessing it’s clogged.

Thank you, gracias 👍

Thanks a lot.

Thank you

[@GreggyGTV]

Is it normal to hear air when you change the diff fluid? I changed the vent plug 20k miles ago amd it’s not stuck at all. I think it was a vacuum noise instead of an air expansion noise. Does that sound right?

[@genxiong2695]

While your at it, you should have run some hose and extended the breather valve just in case in the future you do some water crossings.

[@Emperor_1971]

How often should we change this ?

[@hedwigpoon]

Nice video. Is there also a vent valve for the front differential or transfer case?

[@theotherguy3083]

Yes. Are you asking for Tundras?

[@hedwigpoon]

@@theotherguy3083 No I was just asking in general. I have a 4runner and tacoma I only see videos recommending changing the rear differential vent valve. Where are the vent valves located on the front? What about the transfer case? Where is the vent vale located on the transfer case?

[@tiredoldman9414]

after you put the new valve on, did you have to replace the seals where the leaking was happening? I just saw where you answered the question below. But another one (thanks if you have the time). My 2005 Tundra has had the left axle replaced twice, and the seals redone about 5 times. Every 3 years or so since i bought it new. I never really took the time to figure out what was wrong, just fixed over and over and over again. Now that my truck has 260K miles, and i'm giving it to my son, wanted to fix permanently. Do you think the valve could be causing my long term problem, and why wouldn't any mechanic ever have even mentioned it? i'm going to check the breather today to see if it's clogged. Could something else inside differential be causing this? Leak was always only on driver side. Thanks again for video and any information anyone can provide.

[@theotherguy3083]

Before I answer you, did you do the seal yourself?

[@tiredoldman9414]

@@theotherguy3083 good question. NO! I suck at car stuff. Remember the seals have been done about 5 times at a couple of different places (all professional locations). Since they have failed so many times, I don't think it could be the seals causing the problem.

[@theotherguy3083]

@Tired Old Man you may need a new axle shaft. My experiences is that if it is leaking that much, it is probably bent or worn thereby causing the seals not to seal correctly.

[@tiredoldman9414]

@@theotherguy3083 i just replaced the left axle 1 year ago, and it started leaking almost immediately (about 3 months later). so to recap, bought truck new in 2005. since then i've replaced the axle twice and seals about 5 times. so it has been leaking enough to be repaired about every 3 years or so. the axle was replaced for 2nd time one year ago and it still leaks on left side (always on the left side).

[@theotherguy3083]

@Tired Old Man I'd love to see how they installed the seal. Usually the I stallers do not install them correctly thereby leading to leaks. But try replacing the vent valve to see if it helps.

[@ddk80]

Do you see any issue with adding a brass vent plug to replace the fill plug? I found one online that is the correct size.

[@theotherguy3083]

I would recommend it since brass is softer than metal, you may strip the brass plug.

[@cnclathe3606]

Nyob zoo phooj ywg. How do i get the engine light trouble code for a 1988 honda accord lxi hatchback style? I've seem some vdo on KZbin showing a blue connector under the glove box on passenger side. I looked on my all over & nothing come close to what saw on KZbin. Any idea?

[@theotherguy3083]

Hi. The 1988 Honda Accord is an obd1 system. The correct way to get the code is. 1. move driver seat all the way forward. 2. locate the box on the floor. 3. locate the small plastic window and pop it open. 4. turn the ignition on. 5. count how many times the light blinks Should be long then short blinks.Example 2 long 2 short code 22 Lemme know if this helps.

[@cnclathe3606]

Ok I will try & report to u. Thanks

[@cnclathe3606]

Ok brother, I followed your instructions and found the flashing light; however, it's weird. The light only flash one at a time. One flash at the same speed. No paused flash and fast blinking. Is that means code p01?

[@theotherguy3083]

@@cnclathe3606 yes. If it is a repeated 1 with no pause the code is 1 or 01. This means your oxygen sensor is bad. Replace the sensor.

[@pupsiuspupuliukas2394]

Can you add duff fluid through the vent valve? I mean if the diff filler bolt is stripped by the previous owner..

[@stevanrose7439]

I don’t see why not. It’s an opening to the axle housing.

[@ryeboi1124]

No, don't do it. Your rear end differentials designed to overflow. Once it hits the overflow mark and comes out and you need to stop filling. If you do it through the top you'll have no idea how much fluid you put in.

[@pupsiuspupuliukas2394]

@@ryeboi1124 does it matter as if you overfill it it will come back out through the top anyway?

[@ryeboi1124]

@@pupsiuspupuliukas2394 let me elaborate on why filling the rear differential using the fill plug is crucial. The rear differential operates on a splash gear system, meaning it relies on a precise amount of fluid for optimal lubrication. Overfilling can lead to issues because there needs to be enough space for expansion. When the gears dip into the lubricant, they splash it around, ensuring proper coverage. Filling it to the correct level, as indicated by the fill plug, guarantees that there's enough fluid for lubrication without risking damage from overpressure. This approach maintains the differential's performance and longevity as the engineers intended. Of course this is my opinion.

[@phattidaesalmomykiss9203]

Since you just replaced the seals did you have to replace the seals after installing the valve?

[@theotherguy3083]

It's always good to check if it is working

[@666dynomax]

@@theotherguy3083 I had this problem with my tundra vent. I just freed up the original vent and reinstalled. I was getting wet around nmy pinion seal. Do you think I blew the pinion seal or might it stop leaking

[@theotherguy3083]

@@666dynomax well, here is your problem. If you have a 1st gen tundra, once you have a leak, gear oil will get into the wheel Bearing. That's not good. You'll have to remove the bearing and either re-grease it or install a new bearing. I recommend a new bearing. The reason is because oil inside the bearing will not properly lubricate it. Hope that helps.

[@curtisyang4965]

I'm searching online, but I can't seem to find a torque value on these. Would you happen to know?

[@curtisyang4965]

I was able to find the value, 8 ft lb torque. Seems kind of low, but the part is pretty small....

[@Therealestrunnerluda]

Elbow calibration

[@ryeboi1124]

The torque values going to be low on something like this because your rear end heats up. Lots of contraction and expansion. If it had a High torque value it would get permal locked.

[@landonjamesknutson]

Did the leak stop

[@theotherguy3083]

Yes

[@sirsweetness8332]

This was causing your leak?

[@theotherguy3083]

Yes. Clogged vent valve .

[@MinhBui-ni1by]

This causes the leak because the air has no where to escape, thus BLOWING the seals in the axle tube. Im pretty sure this won't fix that leak. The seals need to be pulled and replaced. The bearings also might be drenched in gear oil and potentially gone.

[@theotherguy3083]

@@MinhBui-ni1by I know I have a sinking feeling.

you can just pull the ABS to check it if it's like my 3rd gen. you might need to wipe it clean first though.
