Transfer Case Rear Seal Replacement (1 Viewer)

[94 TLC]

My 94 has been diagnosed with a ailing rear transfer case seal. While having that replaced, what else should I consider doing in an effort to get economy of scale on the labor portion of the bill? I'll have them replace the speed sensor o-ring - which also may be leaking.

what else?

Thanks!

Not much

3.1 gears or part time if you have ever thought about it and maybe remove the VC.

VC?

VC?

Viscous coupling AKA useless boat anchor
Are you sure the rear seal is leaking or is it just the seals on the speedo drive?? 20$ parts

All that needs to happen to replace the rear TC seal is to drop the driveshaft on the front end of the rear shaft, pop out the old seal and tap in the new one. It's a 15 minute deal.

The only other possibility would be if you need to replace a U-Joint.

How would you get the flange off, torch?

Replace the transmission output seal and the transfer case input seal since the transfer case will be removed and disassembled.
Both seals are the same part #.

I'm about to do this. I luckily bought two seals in case I mess up one of them. If I get the first one in (rear output) without difficulty or harming the seal, is there any decent write ups for the input seal? Any need to replace any bearings in there?

May as well do the bearing while in there. It’s probably fine, but you asked.

I was just quoted for this.

RECCOMEND 80 FZJ Transfer case, Rear output Seal: Replace rear output seal in the t-case. Include new seal and FIPG red.

Seal, Oil Rear T-Case Output 20.74
FIP RED 28.10

Labor 675.00

TOTAL $754
----------------

After reading this, I might attempt this myself if it's as easy as pulling out a seal and putting one back.

You don’t just pull the seal. You have to split the case and disassemble the back half to get to the seal. Is it hard? No. T-case can stay in the truck and attached to the transmission.

plenty of threads on how to do this and even a video on YouTube. definitely wouldn't pay that for it.

Thanks I'll have to look for that video. I have no doubt that shop does quality work. It's just not on my budget

Strongly recommend you replace the output bearing. It's all going to be disassembled anyway since you have to remove the rear section, and then use thin c-clip pliers to disassemble the output. Be extremely careful with the oil pump shims when it goes back together.

@BILT4ME - it isn't like a normal transfer case with a separate flange. The flange is actually part of the output shaft. Not sure why Toyota did things that way since it makes it significantly harder to work on.

Replace all 3 seals... If one leaks then the others aren't far behind. (Input and the two outputs)

Uhhh.....wait....whut?

Never mind..... I was thinking about what we just did on @bpassmore's truck and it was the transmission we did the input/output.......

Ignore the man behind the curtain.......

my front output is leaking. I bought this seal as well. this requires to drop the whole case though correct?

 

[6894kevin]

Looking at the video on YouTube I assume once removed you have to replace the seals anyway. Does anyone know how much the bearing and seals are?

Pretty sure my quote was for just 1 seal

 

[suttonkb]

I bought two rear output seals and 2 front output seals for $20 or so off rockauto
