So I supercharged the car over the winter and had the trans torn down and an LSD installed. Took it out for a test drive and snapped the end of the axle off. Turns out I didnt have it in far enough. So I replaced the axle, got all the metal out and replaced the seal. I set the seal in with a seal tool to about where I would on every car and refilled the trans. A week later, big puddle under the car. So out comes the axle seal and in goes another new one. This one I set .040 further then factory to try a new spot on the sealing surface.... today.... another $50 worth of redline on the ground... I am so Tired of taking the left side suspension apart!!!! I am a mechanic by trade and have never had this issue. My only thought is that somehow the axle has too much movement in the diff or I am screwing this seal up something wicked without noticing. The housing is clean with no cracks or gouges. I saw a post on this a couple years back with no resolution. Ideas? Im gonna be running cheap fluid till I figure this out.

Did you accidentally install an Europa transaxle?

SO I have eliminated the axle seal as the issue. Today when I jacked it up the remove the axle I noticed it was about a 1/4 backed out. I pushed it forward and it locked in. I used a prybar to pry it back out. This is a new snap ring on this axle but it still popped out. I ordered another snap ring and I am going to open it up a little more to provide more tension and try again. I will be running cheap diff oil until this is solved as the redline has cost me over 200 bucks :(

The picture is the view inside my quaife diff on the drivers side. look at the splines, after the splines there is just a void . This is where the clip sits.

This problem was solved by replacing the quaife diff. I have thousands of miles and some on track with no issues. I know its frustrating to find a post like this and not have a confirmed fix.

Ziker, If you recall from our prior PM's, I was having difficulty getting the drivers shaft out. I beat on it for weeks and finally ended up pulling the transmission and taking it to a transmission shop. They looked at it real close through the passenger side shaft inlet then confirmed that the shaft is most likely ruined. I agreed and they beat on it with a blunt rod and big hammer and finally got it out. What appears to have happened is the shaft slipped out when the suspension bolts failed, the n got jammed back in thus spinning the splines of the diff and the shaft literally welding them together. They tore down the trans and replaced the differential. I set out to buy a new shaft. Bought one on ebay but when I got it , the hub side threads were mushroomed over (probably beat on it to separate it from hub). Armed with your previous advise of how easy it is to disassemble and rebuild the shafts, I negotiated a revised price from seller and swapped out the damaged side with the good side from my old shaft. Got it back together, took a couple of easy laps, seems to be fine.

I was going to PM you on this thought it might prove helpful to someone someday to make it public.

Anyway, how long would it take to remove and reinstall a Differential in a C64 transmission. The shop claims that Toyota service says it takes 9 hrs. That is what my guy charged me for even though I think it took him a lot less. (Granted it was at $65/hr not $125/hr). Keep in mind I pulled it out of the car and delivered it to his shop. The shop did a great job and am pleased with work . However I think the Toyota time included removal of trans from car which he did not do.

If you want to find out what the toyota recommended time is first look for R&R trans. Then find out The time to R&R diff and subtract the lower from the higher. If I recall the book gave something like 4 hours. Still way higher than it should be.
