Pictured on the left is the seal that every auto parts store seems to want to give to me. It is a Timkin 223840. Pictured on the right is the seal that I removed from the transfer case. As you can see, they are quite different in construction and in thickness. However, the inner and outer circular dimensions are identical.
What's the deal? Do I have the wrong seal or can this Timkin seal be used? I don't know if it matters, but I have the G52 transmission.
It is a seal that will work !! Most likely has 10 or more things it fits.
Inner and outer is what is critical
Now if it was to thick that would be something else.
If you have the time get one from Toyota as well as a new nut.
I agree that it may work because the inner and outer dimensions are the same. But I wonder if it will fail sooner. I also would be pretty pissed if I put this all back together with the new seal and it leaked. Or started leaking after a couple of months.
This new seal's outer surface is metal where the original was rubber. Will metal on metal seal as well as rubber on metal? Also, because of very the different thickness, it will be seated differently on the driveshaft spline than the original seal.
If the output shaft is scored it needs cleaned up or it will leak.
Put the seal in wrong it will leak
The fact it rides on a virgin surface might be a good thing.
Like I said if you have the time get one from Toyota if it can still be bought.
Most all seals look just like the after market one.
Maybe even the one from Toyota will look just like that. things change over the years
U joint went bad and put stress on the seal, causing it to leak. I just replaced both rear U joints and am about to reinstall the driveshaft once I figure out what to do about this seal. The front U joint had a lot of play in it and was very worn out, causing vibrations while driving and there was transfer case fluid steadily dripping from the output shaft.
Bumping an old thread rather than making a new one.
my output shaft seal on the rear of the t-case gave up the ghost and it’s slinging gear oil onto my exhaust. Are the chain driven seals the same as gear? I have a g58 trans and chain t case. Do I use the same part number listed up above? Thanks guys.
When replacing the seal, I'd also replace the bearing. Sometimes seals fail because the bearing has play in it and that increases the load on the seal. Mine was leaking at 188k and a mechanic replaced just the seal, but then it was leaking again at 9k miles later. I then replaced the seal and bearing myself -- it's the better fix.
FWIW, on my gear-drive case, it was easy to do it all without removing the whole t-case -- I just removed the back housing.
Thanks for the heads up, pretty sure bearing is fine, can’t feel or see any play in the flange. Just need to know if the seals are the same whether it’s chain or gear tcase
