This is rediculous, but heres the rundown. I took my bone stock 99 GSR trans which had a stock open diff and finally installed my OEM ITR LSD. The ITR LSD unit came with new OEM honda sealed cartidge bearings already installed on it. Great, saves me the time of having to take it somewhere and have them pressed on. I pull all the gear racks out of the trans casing, slap the LSD in the trans case with the stock 99 gsr shim (.044) that was already in it, and close it up. I tighten it down, break out my feeler gauges to make sure shes within spec...
Turns out, it has over 1/8th side to side play!!! I pull the housing off, add another shim, (.050) this is now TWO shims, bolt it up, break out the feelers, still side to side play, about 1/16th of an inch. FAWK! pull it apart, toss a THIRD shim (.048) bolt the case back together, too tight, cant even get a .002 feeler in there.
Soo obviously, i need to use a smaller third shim to acheive the proper clearance specs. NOW, heres the reason why it needs all these damn shims. The bearing on the ITR LSD closest to the ring gear apparently was pressed on farther than what the OEM open diff's bearing was. The opposite side measured out the same to the OEM open diff. The only good thing in my eyes, is that the ring gear side with the bearing pressed down soo far,,, is the same side that the shims are on. When the LSD with ring gear is sitting in the trans case with the pinion, it lines up perfect. Which is crucial since thats the business end. In theory and MY eyes, i should be able to get away with using three shims after i figure out which one i need to achieve the proper clrearance specs. has anyone else ever ran into this problem??? Will it work out for me? Or am i doooomed?> lol
If this is hard to read/comprehend i am sorry.

thanks to all that help

You need type r style sealed bearings. The ones you have could be ls/b16 style and they have a different offset on the inner race side opposite of the sealed side. I'll take some pics tonight for you to see. I have never had to use more than 1 shim, but i have seen some weird stuff where people have used the b16/ls diff bearings on the R diff and they put a shim on each side of the diff.

 

well, here she is all shimmed/clearanced. Crazy looking right?



i will be attempting to drive the car today, wish me luck, haha.

This guy is right. The B16 bearing is 1.5mm or so narrower than the GSR, if I recall correctly. The part that is different is the inner race. The inner race protrudes on the R bearings, and it does not on the B16 bearings. Sounds like you got a diff that was originally installed in a B16. The RIGHT way to fix it and not have to replace the bearings is to put a 1.5mm spacer on each side of the bearing in the transmission case so that the gear is at the original "install" height. Or you can spend the $100 on TypeR bearings and not worry about it. The way you have it, the diff is sitting too "low" in the case, and may cause some problems over time.

 

thanks for the 100% correct reply david. After some heavy research, the problem is as you described it 100% to a T. I plan to drive the car for only a few more months till the midwest weather kicks in. Then il yank it apart and buy the quaife unit and do it right. We'll see how much use i get out of it this way, haha.
