s13 nismo 2way lsd clunking... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

driftingpanda · 02-04-2003, 07:17 PM

hello,
i recently purchased an used nismo 2way clutch type (mechanical) lsd for my s13. after install and break in, i initially encountered minor 'chatter', which consisted of light clunking noises. this sounded like metal to metal contact, almost sounds like as if my lug nuts weren't tightened. i was told this is normal, but then...

after about a month or two of street driving and one drift event, the clunking has progressively gotten louder and more violent. now it sounds like three guys with wooden baseball bats going full swing repeatedly at my subframe. this only happens at low throttle, coming out of parking spaces and such, or low throttle 2nd gear left turns.

anyway, i took it off my car, and noticed that my driver side side-output-flange slides in and out about 3mm or so. i took it to a shop and they told me this is normal, and its probably my driveshaft that's making the noise. i've tried everything from lsd additive, to re-break-in, to re-tightening every bolt that relates to the rear portion of the drivetrain.

my question is, does any one know if this is normal? is there anything else i could do to alleviate the noise? any know how the side output flange attaches to the lsd? (c clip, bolt, etc?)

thanks for reading, any help would be greatly appreciated!

happy head-scratching,
danny

as far as your output shaft moving back and fourth more that a 1mm i dont think that is normal. but noise from a mechanical lsd that is normal.

driftingpanda · 02-04-2003, 09:27 PM

racer x: well, it's more than just noise. i've heard other lsd's before, and it doesn't sound anything like mine. it seriously sounds (and feels) like someone's beating the pumpkin with a bat...

thanks to n!xao for the email! i appreciate your input and will try out your recommendations.

anyone else know anything about that nasty side-flange play?

no but if you get any kind of whine then your ring and pinion lash could be off. actually , back in the day when I blew up my 510 R160 differential it made a violent clunking and bangin before it came apart. It was due to bearings going bad. I also was running a 150 hp L16 with sidedraft weber and and delong cam.

My Nismo LSD is the exact same way. sounds/feels like something feel the freak off the car and has been known to make a lady or to squirm in her seat and smile.

mechanical LSD are QUIET. yes i know---i have a 2 way one.
clutch LSDs are louder. yes i know---i have ridden and driven ones.

adey · 02-05-2003, 01:21 AM

Aren't clutch-type LSDs considered "mechanical" as well?
I take it you're specifically referring to the quaiffe type (and stock S15 spec-R type) Helical LSD? ... what's the difference between a quaiffe and stock S15 spec-R helical LSD then, anyway? why would ppl want to move to a "lower grade" 2-way clutch-pack type LSD?

Driftingpanda, I think your LSD is going to explode soon. Maybe you should give it to me before it does that , and go buy yourself one of those $1,200 nismo SSS ones.

Double poster!!! grrr
seriously though
no mechanical, clutch and helical are all different as is Viscous. difference between a quaiffe (I'm not sure theirs are helical) but most likely engagement strength and power holding. quaiffes are garunteed to hold 1000hp. Im pretty sure the nissan factory one would jump out of the pumpkin and kill your first born if you tried that with it

I'm already getting dousan and dorifto a couple of SSS LSDs. Might as well add yourself to the list.

Foxcolt · 02-05-2003, 09:23 AM

Can someone post some info on the SSS lsd's?

Thx

adey · 02-05-2003, 09:34 AM

From what little I've heard, Nismo SSS lsds are supposedly 1.5-way and 2-way ADJUSTABLE... that is to say, you can turn it to 1.5 way or 2 way depending on what kind of driving you feel like doing.

It also costs about 30,000 more yen than the "regular" 2-way nismo clutch pack.

Dousan_PG · 02-05-2003, 09:37 AM

you have to drop the diff and remove the sideshaft to do that though. ugh. too much work.

ruf · 02-05-2003, 09:38 AM

http://www.cyber-ignition.com/News/N00_07/NEWS324.html

Tranlate and enjoy. 8-plate clutch. Adjustable engagement. And the 1.5-2 way selectability like AD mentioned.

I'm going to be trying the Tomei 10-plate. See how that works.

adey · 02-05-2003, 07:03 PM

Daaaamn, you guys have too much money to spend.

I'm sitting here considering a VLSD and you're talking about adjustable nismo SSS and Tomei LSDs. I think you (all of you!) should donate your old LSDs to me! You'd be doing the community a favor by ridding it of yet another open-diffed, tail-happy driver.

What else makes the Nismo SSS so much more expensive, or was that about it? I thought you could adjust breakaway torque on regular Nismo 2ways and Kaaz 2ways as well. (requires rebuild of diff...) No?

driftingpanda · 02-05-2003, 08:22 PM

u guys ate up my thread!! anyway, nismo SSS is the best lsd because it allows your car to slide like a winding snake... sssss....

turns out, the output flanges are floating shafts, held in by c clips, so the 3mm play isn't a problem. after re-cleaning and re-break-in, i stuck the thing back in this morning and ran some mopar friction additive, now my nismo posi-tract rear end's clunking has somewhat reduced. with the whole bottle of lsd additive, the engagement seems to have been softened, but the clutches still grip the same.

has anyone had any experiences with different brands of friction modifier? any recommendations?

as for adey... WE have too much money to spend? if you had just listened to me and bought used tires instead of all of them bridgstones and dunlops you'd have an lsd by now!

happy clunking,
danny
