Transmission extension housing seal. Kind of a PITA.

I followed this guide but ran into some problems:

http://www.tacomaworld.com/forum/2nd-gen-tacomas/270255-diy-how-replace-output-shaft-seal.html

The write up was in the 2nd gen forum, but the pieces are basically the same.

However, this is what I ran into.

First, the A43D (2wd 4cyl) transmission has a dust cap and felt dust ring in front of the seal itself. This in itself is a huge pain to remove and install. Unlike the seal it's made of soft steel and bends if you look at it funny, both removing and installing it.

Second, in my truck the handbrake lever and cable assembly was right there in the way of getting good leverage on the pick-type seal puller, or being able to drive the new seal straight in. If I do this job again - and I might need to because there's a good chance I messed up the new seal getting it in - I'm getting a jaw-type puller.

My old seal was definitely damaged, the part that contacts the driveshaft itself to form the ATF seal had broken off and was just sitting in there like an O-ring.

 

Did you remove entire extension housing or just the driveshaft seals?

 

I don’t think you’re going to get an answer from him. It says the last time he was on here was Oct. 23rd 2014

 

I’m hoping that someone can help me out with an answer. I have a leak, and am trying to figure out what I gotta do to resolve it.

It is actually one of the most simplest prepared jobs that you can do Under your vehicle. This is all you have to do and there's only about 4 or 5 steps remove the 214 mm bolts holding the support carriage for the drive shaft make sure to hold the drive shaft up so it doesn't fall on you when you take the bolts out. Then fold the U joint on the drive shaft down and slide the drive shaft out of the transmission. And there you have it the seal is right there behind the drive shaft around the entrance to the extended extended housing on the transmission. Use a seal puller to pull the old seal out if it's stuck in there and take your new seal and place it on the opening and use APVC pipe fitting that's the same size as the lip on the inside of the new seal and gently tap it in with a rubber mallet and risk and reassemble the drive shaft And you're done!
