vg30e_x2_200sx on 07:11:33 AM / 24-Oct-10 I beg to differ on that. I had both an 87 and 88 SE the the flanges were different. I don't know if it had to do with the fact that the 87 was an auto and the 88 was a 5sp but I did a temp swap with the 88 diff into the 87 do I could do some maintenance work on the diff and still drive the car and to my surprise I had to swap the flanges so I could bolt up the drive shaft.

Were they both SE or one was a CA20E. Because I know R200 and R180 have different flange but I also thought all R200 had the same flanges

Both SEs. Check my name.  Wink

that was for the driveshaft only or both the driveshaft and the axles?

That was just for the driveshaft. The axles don't bolt up, they just slide in.

Just curious - has anyone attempted using the Q45 VLSD in an S12? I tried the search function and came up empty.

I THINK that's an R230 (don't quote me on that) so it wouldn't work.

The ring gear to drive pinion backlash for the H-190 is 0.15 to 0.20mm or 0.0059 to 0.0079 inch. As for the torque down.... that's to vague as there are lots of things that are torqued down on the diff. from the drive pinion bolt to the oil drain and filler plug.

Anyone ever find where to get a clutch type diff at a reasonable cost?

alundraOct 30, 2010, 11:24 am · #10

clutch LSD?reasonable cost because it needs to be controlled for worn, needs to be rebuild etc...

Hope someone one day try a a CLSD for an s13

I'm using a X32 VLSD in mine, custom halfshaft. no easy task.

Developed a thumping somewhere in the back under heavythrottle after about three or four years of use. Need to pull my tri-pods apart to inspect them.

Its an R200 for sure, but I figured there might need to be some work done because of the halfshafts.

I only ask, because I have one laying around here, and didn't know whether to post it for sale here. But if it won't be of help to anyone, I won't clutter the for sale section. LOL

i put it bak together alrdy  torgued down the 4 bolts on the diff to 40ft and im guessing my backlash is around 23 wit the tiny tiny play it gots.  but im nt sure something is making a clicking noise when i speed up then put the tranny in netural and let it coast to a stop. i lookd around on the internet for clicking noise im guessing its the wheel bearings they mite neeed broken in im gonna drive it today and c if it stops if nt im gonna try packing some grease in the wheel bearings.

When taking apart did you mark the bearings and their locations? If replacing bearings the diff should be set up properly to get the correct back lash. The side bearing cap bolts are 30-36 ft lbs. I guess 40 will be OK.

The ring gear to drive pinion backlash for the H-190 is 0.15 to 0.20mm or 0.0059 to 0.0079 inch. NOT "I'm guessing 23". If this isn't taken seriously, next time you change the oil because of that growling sound next spring, it will look like aluminum paint

drake_fistNov 2, 2010, 11:17 pm · #15

no i didnt mark the bearings lolololol omg im just learning the hard way now ainte i......im goin to break it down again some time soon and shim out the backlash it should  last me a few hunderend miles witout hurting it i hope  lol and buying the shims takes for ever cuz i got to locate them sad face from different dealer ships around the usa.. i would of put it together the right way if i didnt need the car so bad for work...one of my buddies has a backlash dial or w/e. ill check the oil tomorrow and c wut it looks like if theres to much shit on the drain plug ill park it and ask one of my buddies if i can use his car to get around. ill keep u updated.

i took the drain plug off after 135 miles theres some shavings just little ones but all bunched up so i took the rearend apart as i was taken it apart i seen that the dust shield that holds the shaft in wasnt bolted down all the way i guess i missed those bolts but i still took the pumpkin out goin to meet up wit one of my friends and check the backlash and teeth patteren friday some time. and hopfully its in spec so i dont have to break down the pumpkin lol.

I found out wut is wrong wit i gotta shim the left side of the diff so the pinion and ring gear meet up more. and it should be 100% rdy to go and last me another 26 years i hope.
