Ok...time to get the E-brake hooked back up and the leaks stopped.
Earlier in this build thread I pulled apart the E-brake as it was missing a retaining clip and had ground itself up. I ordered a new E-brake parts kit as well as a Valley Hybrids modified double seal speedometer housing but have yet to get them installed....well today is the day!
First up I drained the oil out of the transfer case. Then I removed the drive line, the E-brake drum, speedometer cable & Drive, and the E-brake backing plate. Here's the leaking seal on the back of the speedo housing.
4 Bolts and the speedo housing is removed. I'll clean up the gasket material and get the surfaces prepped for the new gasket.
Here's some pics of the Valley Hybrids modified housing. They machine the housing deeper to allow two seals to be utilized instead of one, ensuring a better seal and a leak free driving experience. The kit comes with everything you need to complete the job minus sealant.
Changing out the O-rings on the speedometer drive. There are two O-rings to change out here (Provided with the kit), one internal and one external.
The internal shaft just slides out of the housing. There is a notch to line back up upon re-assembly.
A pick works nicely to remove the inner O-ring.
I used Loctite 515 on the speedo housing gasket.
Speedo drive and cable back in place.
Re-installing the backing plate. 11.5 ft lbs.
Assembling the new brake hardware.

Continued from above...
Ensure your seal surface on the drum is smooth and not chewed up. Apply a light coat of grease here as well. Pic taken before the drum was cleaned up.
I cleaned the end of the splines/threads then re-installed the drum. I used Loctite 515 to seal the end of the splines, oil leaks here otherwise.
Torqued to 94 ft lbs and staked the nut.
Drive shaft re-installed.
Time to change and re-fill the vital fluids. I drained and re-filled the transmission with Redline MT-90, MT-90 is a GL4 oil and is designed to allow synchronizers in the transmission to function properly. I've had great luck with MT-90 in the past and usually results in improved shifting. I drained/filled both axles and the transfer case with Valvoline 75w-90 syn. While I was there I also topped off the knuckles on the front axle with some Caterpillar Extreme 5% Moly Grease (Cat part# 452-6016).
Drove the 40 all day today and not a single drop of vitals fluids leaking so far, E-brake is working perfectly again. Sweet!

Took the FJ40 & the M38 to our local car show, Cool Desert Nights. Did the cruise on Thursday night and we had four 40's in the cruise...way cool!
The show was great and we spoke with a ton of amazing people. Sooo much fun. The 40 took a first place award!
We arrived early to get a nice spot In the shade...1st and second in line
Had another 40 as company. Way cool.
