DIY: Toyota 4x4 Transfer Case Rear Flange Oil Seal Replacement

[@matthewhirschy6902]

Thanks for the video. I have a lexus gx 470 but the tranfer case is so similar it made the job easy. Yours was the only video on here that i found.

[@determination6176]

I had the same problem where I couldnt find a detailed video of how to do this exact job, but on my v8 4runner. I guess that if it went well for you on your Gx, it should be good on my truck too, since the both share a lot of parts! Thanks

[@brockdavidson2130]

Had me rolling when you pulled out the flathead but in a professional manor. Nice video!

[@Samson-EC]

I did not understand why you need rtv stuff. Shouldn't the seals keep the leaks out? Is the black rtv silicon?

[@6thGearGarage]

Just extra insurance I guess. Yeah I used black RTV

[@Samson-EC]

@@6thGearGarage ok, great video thks..jc

[@TheDatsun720]

I agree

[@BilderbergCEO]

I get that the drive shaft sections need to be aligned, but does it matter if the flanges at the ends of the shaft are aligned with transfer case flange and the differential housing flange? I ask because I'm installing a whole new shaft.

[@6thGearGarage]

I don't think those matter as much (if at all) but I mark them as well because I don't want to find out the hard way.

[@deeeyewhy5949]

What about dong the seals where the t case meets the transaxle? Looks like there is a bead of red silicone pressed between them.

[@6thGearGarage]

That red silicone is most likely Toyota FIPG (form in place gasket)

[@deeeyewhy5949]

@@6thGearGarage can I use an RTV? I doused the engine and transmission seam with pb blaster and the protruding gasket material just disintegrated (it came of when I touched it) so I think I should take the t case off and redo those seals. As well as both output or the input and output shaft

[@6thGearGarage]

@@deeeyewhy5949 I think an RTV would be fine.

[@SHETTE08]

hi .... is this seal the same for a 1996 toyota 22re engine? will the transfer box be the same? you will have the measurements of the retainer please

[@6thGearGarage]

Toyota says it fits 1984-1995, so it will not be the same for 1996 Tacoma.

[@misterpolytech]

Was the oil seal failed because the staked nut was coming loose, causing play in the transfer case output shaft? On the YotaTech forums, this is reported to be the cause of a lot of the seal failures; in most cases it seems that tightening up the stake nut and re-staking it after replacing the seal fixes the problem; however in some cases it seems the output shaft bearing behind the seal ends up going bad and also needs replacing....

[@6thGearGarage]

The staked nut seemed alright. I think it might have just been high mileage. The truck had about 190k when I did this job.

[@hugocarreon9776]

The rear seal that you used in this video, can fit y the transfer front output shaft?

[@6thGearGarage]

That I do not know. I would cross reference the parts from Toyota to be sure they're not different numbers.

[@iowabuckinrut760]

Did you have to drain all the oil before doing this? Or is the oil level just below the seal so only a little spilled? Thanks

[@6thGearGarage]

I did not have to drain the oil, it’s below the seal 👍

[@caruthman2825]

Hi, I have a Toyota Hilux Ln166 2001 I’m having trouble finding the original seal. Can you please help me with the part number. I changed it and there is still a leak.

[@6thGearGarage]

I don't know as we didnt get the Hilux in the US after 1995. Did the dealership confirm you had the right part? Other causes could be damage during install, or wear on the shaft itself.

[@MrPinaTransam]

What's the part number for the seal.

[@6thGearGarage]

it's 90311-38140, for 84-95 4wd pickup/4runner

[@fshnpro113]

Would this work on a 90 pickup with the 3.0 v6?

[@6thGearGarage]

The part is probably different, but the process will be similar.

[@fujimori17]

Hey man great video, I have an 87 4runner and I think mine is leaking but in the front where the front driveshaft connects. Is the procedure pretty much the same? Looks like it might be a little more involved but if it's pretty much the same I can probably knock this out next weekend.

[@6thGearGarage]

Yeah the front companion flange removes the same as the rear, with the staked nut.

[@fujimori17]

@@6thGearGarage alright cool, I guess I tackle this next weekend. Any chance you have the part number for the seal and the nut? I would think they're the same, no?

[@6thGearGarage]

@@fujimori17 ​ Fuji Mori I just checked the FSM and after the staked nut & washer, things are different. The front and rear oil seals are the same size but FSM says they are specific to front and rear because they're designed for the shaft to rotate one way in them. The front one has the word FRONT stamped on the outside. They don't say any part #'s.

[@fujimori17]

@@6thGearGarage dang, well thanks man I really appreciate it. I'll have to call the stealership and see if I can get those part numbers.

[@jimmydrakopoulos2140]

Hi...did you do seal from crankcase? Did mine twice and leaking...

[@6thGearGarage]

No, I only put the RTV on the flange at 5:50. Is yours leaking from behind the flange?

[@markmahecha8974]

Mine didn't have a washer. Does anyone know what size of a washer I would need?

[@6thGearGarage]

I don't but I bet the dealer would have the part, it was used in many years of 4x4's.

[@RippSnortin]

Isn't there a second seal also?

[@6thGearGarage]

On this application there is not.

[@edwincamiling2644]

What to do if the thread is damaged and the nut cant tight

[@6thGearGarage]

If the nut is stripped, you'll only need to replace it. If the threads on the shaft stripped then you'll need to remove and tear down the transfer to rebuild it.

[@edwincamiling2644]

Thanks for the reply.what do mean "to remove and tear down the transfer"?

[@6thGearGarage]

@@edwincamiling2644 You'd have to remove it from the truck and take it all apart to replace that shaft, if it's even available anywhere new. Might be easier just to buy another used transfer.

[@alejandromontoya3591]

6:56 What is that sound? My TOYOTA 4x4 makes that sound every time I accelerate and decelerate.

[@6thGearGarage]

Alejandro Montoya the Click Click in the video was from the torque wrench. I haven't heard that kind of sound on any of my trucks while driving, but you might check for slop/play around the driveshaft/u joints if it happens when you accelerate/decelerate.

[@alejandromontoya3591]

​@@6thGearGarage Thanks for the advice, but apparently it was the transmission oil that was expired and with low level. After the change, it stopped ringing.

[@DirtGarage]

Sweet truck! Just subbed, need to replace same seal in mine.

[@6thGearGarage]

Thanks, just checked out your channel and subscribed as well. Nice build you have going!

[@DirtGarage]

6th Gear Garage Thank You!

[@adrianhigareda6461]

6th Gear Garage Is that oil seal the same on a 2 door model it's a 88 2door 22re I recently had the same problem it's only been a pain in the but finding the part number

[@6thGearGarage]

I think it depends mostly on which transfer case your truck has. Mine has the forward shift design, 21 spline. All have 21 spline except the turbo models. Most 22R 2nd gen 4x4 had the fwd shift, while most 22RE 2nd gen 4x4 had the top shift design. Still not sure if they use the same seal. I checked my repair manual and it didn't say.

[@adrianhigareda6461]

6th Gear Garage thanks for responding I'll look that up thank you very much.

[@jasonsizemore6037]

Is there a bearing in there to change? Mine leaks oil like your did. But also has some play in it.

[@6thGearGarage]

Yeah I'm sure there's a bearing, although I've never torn into the case to see how to change it. I'd pick up a Factory Service Manual if you don't already own one. It's worth every dollar.

[@mikeymcnair4286]

this work on a 92 v6 4x4?

[@6thGearGarage]

I'm not sure, as I've only worked on the 4 cyls

[@timdilworth1430]

What wheels are those they look good?!

[@6thGearGarage]

They're Fuel Anza, 15x8" that I painted bronze & red - Thanks!

[@jdhitc]

Would you use the sealant on a pinion seal??

[@6thGearGarage]

No I would not use sealant on a pinion seal. I have a pinion seal video too.

[@reinhardtrippmacher8776]

Hi, thanks for that video. I am having a landcruiser 1hz, 80series,4.2l diesel. 1992. My front output seal leaks a bit. I check the transmission case oil regularly but there is always enough oil in. Is the transfer case oil and transmission oil the same? Replacing the transfer case oil seal on the front output is a bit more complicated as I have to take off the whole casing in the front.

[@6thGearGarage]

The Transmission and transfer case each use their own oil. I'm not sure on the 80 series, but on my 4x4, there is an upper and lower fill bolt on the back of the transfer case where fluid can be checked.

[@williampimentel9036]

I have a 84 Toyota pickup single cab long bed about 151,000 just wanted to know does it have a plastic guide or metal guide for timing chain

[@6thGearGarage]

William Pimentel oem guides are plastic but there are metal aftermarket guides available.

[@williampimentel9036]

Ok kind of a fork in the road it hasn’t gone out yet but I also heard that it once they go motor is blown up is that true just trying to keep the ole girl running my daily driver lol thanks

[@6thGearGarage]

Nah, they're wear items meant to be replaced. The only way damage can occur is if you keep driving after its time to change them, along with the tensioner. Slapping chain sound means it's time.

[@6thGearGarage]

Also I prefer plastic over metal because if you replace them on time, there's no advantage for metal. Id rather not have my chain rubbing on a metal guide.

[@williampimentel9036]

True true thanks man your video on the driveshaft support bearing is really gonna help me out when I change mine soon thanks again love your vids

[@liverpoooley]

Hello i have an fzj80 1996 land cruiser which i have been suffering from bad vibration in speed around 90km to 120km i changed the drive shaft twice, but u said an important note in ur video .. that it needs to be marked “u marked it with yellow” otherwise the drive shaft will vibrate! I guess u find the solution which i was looking for for a month!! Do u know how can bring back my drive shaft to its orginial factory calibration? Thats will help me alot. Thanks waiting for ur replay

[@6thGearGarage]

The free fix is to unbolt the driveshaft, rotate it a quarter of a turn, and re-install it. If it doesn't vibrate on a test drive, then it is installed correctly. If you tried every position and it still vibrates, then you may need to have it balanced.

[@liverpoooley]

6th Gear Garage great thanx for the replay .. yesterday i went to a professional mechanic in toyota trucks, he took a quick look for like 15 seconds under the car and said the transfer case is the cause if the vibration and i knew it leaked might bs bearing or flange of the drive shaft in the transfercase.. do u think the transfercase might make this vibration on high speed! Appreciated really ! Thanx 👍🏽

[@6thGearGarage]

I haven't had the luck of experiencing a bad transfer case as of yet, so I can't speak from experience there. But generally a bad bearing in a transfer case or transmission will be more noticeable at certain/higher rpm's.

[@liverpoooley]

6th Gear Garage fair enough thats true cerain and higher rpms true! Thanx really wish u all the best and keep it up for ur nice channel u hv in utube my friend

[@blackdogprospectingwelding7341]

I’ve looked and looked and cannot find this part.

[@6thGearGarage]

Here is the exact part I used, but you may want to double check it fits your truck if it's different than mine. amzn.to/3t3zdKA

[@jimmydrakopoulos2140]

Thanks for your reply. Mine is leaking from the crankcase. I Will attempt another try on Sunday.

[@somechannel7083]

Very helpful thanks!👍🏻

[@tacticalant3841]

2 transfer case shifters??

[@6thGearGarage]

It's a twin stick setup. It gives you separate controls for 2wd/4wd and hi/low. Nice when in a tight area with front locker because you can go into 2wd low and have a better turning radius instead of fighting the front diff when steering all the way right or left.

[@soriar66]

Can’t remove the nut my problem it’s the indent on it any suggestions?

[@6thGearGarage]

You'll need to punch the indent out using a hammer and a punch tool.

[@jakesemo3415]

I can't remove my flange I took the nut out but it still won't budge any tips????

[@6thGearGarage]

There's a tool for when that happens, google "flange puller" and some for sale should come up.

[@6thGearGarage]

Local parts stores will probably have them for rent too.

[@TRyan-op2jo]

Awesome video! Thank you!

[@Yesterdie02]

Not sure why you used the RTV it’s not needed. Other wise good work
