View Full Version : Quaife LSD Install into an E153

So back when Prodigy was buying all the parts for his swap, he decided to go with an E153 tranny and Quaife LSD. However, he decided to move the timeframe up on the 3S swap we weren't ready to put the E153 in, so we ended up doing the swap using the S54 (swap was done in 22 hours over 3 days).

This past week, his throw-out bearing decided to bite the dust, and since we had to pull the tranny anyway, we figured we might as well go ahead and do the E153 swap. The tricky part is first we have to install the Quaife LSD. I'm a huge fan of Quaife and have been for years, but I've never actually installed one before.

So, I've got a few pics and I'm hoping for some advice :D

I knew that the c-series transmissions could be taken apart to access the diff without removing everything the "normal" way by unbolting the case, splitting it apart an inch or so, and then unbolting the reverse lever. I was hoping that the E153 worked the same way, and sure enough, it does:




Old diff and quaife:


Bearings, ring gear and speedo gear being removed and transferred over to quaife:


Awaiting a new bearing, etc


So, the diff came out no problem, and from there I knew that I had to swap over the ring gear, speedo gear, and both bearings. One of the bearings came off with a three-jaw puller with a little fuss. The other one, unfortunately was damaged when the puller slipped on our fourth or fifth attempt.

What I'm trying to figure out is:

1. Can I replace just one of the bearings, or since we have to replace one side do both sides have to be new?

2. Do I need to be concerned about measuring bearing pre-load, and if so, how do I go about doing that and how do I adjust it?

3. Anything else I'm missing?

This is one job I would have happily paid a transmission shop to do, but everyone that we spoke to locally had NO CLUE what they were talking about when it came to a FWD LSD.

Thanks guys :)

What ever happened with this?

Did anyone ever answer these questions for you?

Obviously I am doing the same project soon and would like any knowledge you care to share so I can pass it along when we work on mine.

Yes, check the preload on the diff. If I were you I'd replace both taper bearings and also the races on the trans, you'll also need to check the shims to see if you've got the proper preload. Doing that would probably also mean you'd have to replace both axle seals as I think it'd be pretty tough to get the races out without destroying the axle seals.

TIS says with new bearings (and races) is 0.58 - 1.16 in-lbs

Or with reused bearings 0.36 - 1.72 in-lbs.

Thanks for asking :) Actually I have completed the Quaife install and I did it all the RIGHT way, but it was quite a process. In fact, I just got it in the car this past weekend. I was waiting to get the axles all figured out and have the completed pics ready to share, but since you asked, I'll spill the beans early.

First of all, no one knows anything about measuring bearing preload. Everyone I talked to, including people who install Quaife LSDs, either had no idea what I was talking about, or knew about it but said something to the effect of, "oh yeah, we always skip that part" or "oh, I just do it by hand".

This whole situation really concerned me for two reasons. One, it went against the way I do things which as most of you guys know, is by the book and the best I possibly can. Second, I didn't want to burn up a $1400 diff! So after getting to this point in the build, I determined where the shims were located and how to replace them to measure the preload, as well as what order to do it in (that was a little confusing in the manual). Also, I had to purchase a 0-30 in/lb range torque wrench since nothing else would measure accurately down that low. That took a while to find.

Finally I got it, and also bought a press to properly install the new bearings (I did replace both sides). First I did the initial step of measuring the preload which you do with only the output shaft. Once that number was determined, I did it with the diff and output shaft installed.

With the output shaft only, it measured just barely on the high side for used bearings which I felt okay with. Then I took the case back apart and installed the diff. As soon as I bolted the case back up I knew that it was too tight since it was hard to turn the output shaft by hand. I measured it and sure enough, it was way out of spec (too tight). This was a little frustrating because I would have to order shims from Toyota, but at the same time I felt validated about making sure I checked the preload.

The next weekend I got the shims in, and I had decided to go just one step down on the output shaft shim as well to get it into spec. That part went fine. Then I started going down with the differential shims, one at a time. I took that case apart and put it back together like 6 times that day!!!! But finally I got it perfect, right under the top of the range. I had ordered several sizes of shims to make sure I got the one I needed (I ended up going down about 3 sizes. There are like 20 sizes in total).

It's been a pretty long process but the experience I've gained (and the tools I've bought!) will be invaluable for future installs :)


Pressing the bearings on:


Preparing to bolt the case on to measure preload:


This was the catalyst that inspired us to put the E153/Quaife in. This disc was a cheap one made by a local clutch shop, it was only supposed to be in there for a couple weeks while we installed the Quaife. We didn't even start working on it until about 4 months later when it blew :)





The broken springs got behind the flywheel and chewed up the rear main seal housing. It was okay though thankfully.


Putting the E153 together for the LAST TIME!




Bolting it up. It's a tight fit in the Celica.



Why yes, that is a Quaife!


Right now the axle guru is busy figuring them out, and then we'll put it back on the road and try it out! :)

hrm, that looks like a lot of fun.

Little update, finally got the axles figured out. Got a sweet setup that works perfectly using off-the-shelf parts.



The car is just amazing with all the traction. Next up is tires, springs/struts, exhaust and boost controller.

what axles u end up needing?

I actually need to go by the axle shop and talk to the guy about that, he has it all recorded for me.


04-10-2009, 06:26 AM
looks good, hope everything works out ok. lets us know about them axle's

All I have to say is.... Tweak you are a brave, brave man. lol. And your perseverence and commitment to do things right is commendable.

I have read a few threads on breaking open the tranny and WOW!!!, something I would never even attempt. Just thinking about it makes me piss my pants. lol.

Very clean install tho. I'm sure it will last for hundreds of thousands of miles.

What did you learn from the axle shop?

Dr Tweak
04-21-2009, 07:42 PM
I learned that I have a source for axles LOL. Let me know if you need some. They aren't something you can build with off-the-shelf parts, let's put it that way.

I thought you once said that if someone was already using an E153 and it worked fine, then new axles would not be needed if a Quaife was added.

Is that still the case?

04-21-2009, 07:56 PM
Now figure out how to modify a quaife to work in a 185 box.

Should be no problem as far as I know.

Yeah of course. A lot of people using the E153 in 6th gen Celica have axle problems, thus my comment.

Like I said at the meet Tweak.. I've got an E153 that I've gotta get up to you just for this!!! Excellent stuff!

Might as well, I bought all the special tools for the job! :D

BTW Prodigy's put probably a couple thousand miles on this setup and it's been running perfectly so far :)

I definitely will! I'll try to get up there in a few months, I'll swing by and drop it off in the box. We'll chat soon via PM about it all.
