I think i stripped mine😔😔 imma try to see if i could still do it tomorrow

wait do you really not have to loosen those 12 bolts? bc I wanna buy a Y38 diff and that diff I'm buying doesn't come with the stub shaft. so I'm wondering can u just use a crowbar as he did in the vid to pry out the stub shaft and not have to waste time loosening those bolts.

I also am wondering about this if someone can explain the purpose of it.

@@gurpreetsoomal5408 Well... the side-gear-shafts will ultimately need removed from your old diff and over to the frs diff. Easier said than done while diff is in the car and axles are attached. It would be (was) way faster to undo 6 hex-socket-head-cap-screws on each side. Makes installation easier too. IF you are on a lift then pick your poison, but on jack stands plan to use a 8mm allen socket on those axles THERE (with the parking brake on at the right times). Safer with the diff out of the car to back off the side-gear-shafts using two longer bolts on opposite sides (against a brace on the diff): you don't want to damage any of the finer tolerances in the left/right spline section with uneven removal techniques (hammer/pry bars). I was able to use the old snap rings, and the outer/only rubber oil seals were good on my y38 BUT these are worth getting if you're able to source them. I drained/filled the y38 with 75W90 synth AND lsd additive (about 1.25Q total). TWO Crush washers (90430-A0003) are prudent, torque back at ~35-39 ftlbs after drain/fill.

@@Bellgrande I would plan on it - unless you have parts and car lifts.

He was probably hedging a bet. For those of us with just jack stands plan to remove the axles first and the side-gear-shafts later (out of car) with 2 longer back-off bolt. I had to drill a tad of the y38 ear bushings to get the stock is300 bolt thru using a christmas tree bit, btw. Anyway, I just finished my y38 swap, into a 2001 IS300 with a650e 5-speed auto, replacing a open M96 = 3.91:1. Without vehicle/tranny lifts, took (brutal) 13 hours. Pretty happy with the results, now learning how to drive all over again. BTW, take the 5 minutes to completely remove your rear sway bar (and install some TRD yellow or reds in there!)

Anthony Norris lemme know when you get an answer cause I need one

It does and the y38 lsd from the frs/brz/86 also fits the is300 and is250

The tag on it will give you a number such as “m96” or “m98” the forums will tell you which is lsd

@@kenlyc3762 should swap out my m85 to a m98

@@zakkrick I have an m98 if you wanna trade?

M98 IS THE AUTO LSD. MAN LSD DIFF IS AN M85 LOOK IT UP IN THE IS.FORUM....

@@zakkrick look on EBAY there's 2 in SoCal for less then $600 and in great shape. I'm about to order one....🤙😉 For my 05, along with an 06 IS350 steering wheel to do the swap.

That was PB-Blaster. Shit works amazingly for busting nuts loose

Hey did you have to get the rear end of the driveshaft to do you m85 swap

@@sirachacha1955 took me a few hours to do laying on my back on the driveway. You don't need a new driveshaft or anything; it's a direct swap with your existing one.

Not all of them, it was a option from factory to have a LSD or open diff, and there’s also different versions of LSD’s and open diffs between manuals and autos

i have a garage at my shop but i work at a shop and some times use their hoist

I think you may have it the opposite way around. Yes, the M85 is 3.73 vs the M98 at 3.91, which means M85 has longer gear ratios. M98 should have better acceleration, but less top speed. Turbocharged applications may prefer the 3.73, since boost excels with longer gear ratios. The longer ratio rear-end is preferred on most transmissions except for the T56 which would suit most people with a differential final drive somewhere between 3.8-4.1.

I believe you need a mark 4 supra diff for the sc400/300

its the m98 for an auto is300

Torsion

I have one id sell

goocherrific really ? Can i get in contact with you

Sure shoot me an email. My name at Gmail dot com

use a BRZ diff instead its bolt on and cheaper just use BRZ diff bushing bolts for a perfect fit

@@asian380 i actually just picked one off of an FRS , ready to put it in does it matter if the frs was stick if im putting it into my auto ?

It locks under load.

i sent a couple set i should probably get a vid
