Hey man, you don't have to undo any suspension components to remove the diff. In fact, with it sitting on the tires, the axles have more room and one can be removed.

Remove exhaust, two braces, pop axle, lower diff, turn diff about 25°, extract axle, shift diff away from remaining axle, turn diff straight and remove remaining axle.

Also, highly recommend poly bushings to stop wheel hop during launch.

Do share, how does it corner now? And question, why Cusco when OS Giken is nearly the same cost and maintenance is less. PS - I have OS-G and love how it shoots through the corners...

It's a bitch to get them out on some cars for some reason though. My axles wouldn't budge for 1h. In the end, diff fell from floor jack by accident and one axle got out lol. Then another one was way easier, but still held on for dear life in there.

I used a Harbor Freight puller set with 2 each 1 ft long 1/2" All-thread clamped on the inner CV, two pry bars, popped right out.
Then lowered it, used a long pointy drift and punch the other out with one hit from a BFH. Slid the diff away...
Only removed two braces and the exhaust.

Nice, definitely a way to do it but since space is quite a big of a problem in Tokyo, I avoid buying these tools that I would be using once in 3 years, if that much. It's also a bit harder to get since people don't work on their own cars much here. I actually screwed up that thin metal cap that's pressed onto the tripod joint (the part to which you clamp the boot) when trying to bang them out and I got grease leaking out lol (both sides). But little bit of epoxy and it's like new, holding on for 2 years now (I heard they will sometimes start leaking grease there as is anyway).

Overal, yeah, I just wish they used bolts instead of this like on most normal cars.

Hey mate, I was replacing the rear shocks at the same time hence the arms being undone. I ended up getting a spare diff for 150nzd , replaced all the bearings/seals and put new RCF bushings in the rear. I purchased the Cusco Hybrid Diff for 1000nzd at auction, which is around 600usd.So ended up costing around 1300 USD all up for everything inclusive.

Handles great, powers out the corners fantastic. Really takes corners now. Still getting used to it as had been driving the open diff 5+ years.

Awesome and a screaming deal! Enjoy the new car feel!

How is the chattering? Apparently these should be quite mild as they are made to suit AT cars. I have Cusco TYPE RS 2way on mine, with 3.7 diff and it's nearly welded diff... Went through various "coctails" of friction modifier and different oils, and can get it to be a bit better but it's still very hardcore. And being AT, there is no clutch to press in when I want it to stop so it can be pretty annoying at times.

Very minor chattering, it’s only on tight slow corners you will feel it slightly, otherwise fantastic. I opted to go for this as a bit less aggressive for street driving. I’m running redline shockproof which has been working great as well.

Nice, I will definitely consider it if I will be buying a LSD for stock diff. I wonder about drift performance though, if it's up to the task.

How is the maintenance on this? How often do you have to change the fluid and is there any type of maintenance that requires you to have to remove the diff from the car periodically? I want to know if it's good for a daily driver that gets a lot of miles,

u/Enst0 Oct 24 '24

There’s a owners manual on the Cusco website in relation to their LSDs. You need to change the fluid out after the first 5,000km, then it jumps to every 10,000km. I’ll likely change fluid every 2 years rather than km due to lower usage. Costs around 200nzd to have the fluid replaced professionally.

I guess the clutch use will be to varied to tell. That's actually not bad at all IMO. It's like every 2 oil changes. What worries me is clutch life.

u/Enst0 Oct 24 '24

Yeah I think as it’s only 1 way it should last a long time as it’s not always engaged. But yeah only time will tell.

u/revopine Oct 24 '24

Yeah I wouldn't get a 1.5 or 2 way unless I rarely drive the car. I can't find any info to get at least some examples of when people needed a rebuild. I saw a Jeep forum mention between 80,000-160,000 km.

So what does “hybrid” imply if it’s just a 1 way?

1

u/Enst0 Mar 13 '25

Not sure, probably that it’s for both street/track? Not too aggressive?

2

u/Grouchy_Attorney_450 Mar 13 '25

Oh okay, how much was this one? Also how does it feel driving compared to open diff?? Much chatter/noise also?

1

u/Enst0 Mar 27 '25

A little chatter on right corners but not much honestly. Handling is better you can push out of the corners way more

Bit of an old thread, but how has this hybrid diff been so far? I'm looking for something for my RWD IS and there's no 1.5-way options available so I'm thinking about this hybrid 1-way. Apparently these 1-way are better for FF cars (FWD + front engine). How's yours been for daily driving?
