It's most likely to be the subframe movement. mine does that too. Get the car on the hoist then get some light and look where the cradle connects to the body. U'll see the marks on the body from the bushes on the cradle and the gap in between. get some subframe bushes to stop that movement.

[Big Boss]

thanks guys, it's got to be the rear cradle i don't think any other parts of the drive line can be so clumpy!, that sux rear cradle is going to be hard to put back on!

while i'm at it i should probably replace all the other bushes too, i'm going to look for some pineapples and urethane bushes, i know i can't get alloy spacers

[NRG180]

Yeah urethane stuff should make big difference. I hear that alloy spacers make it too noisy with vibrations. Let us know how u go.

[J_Spec]

I have alloy subframe spacers. They work well. I noticed a slight increase in noise but it makes drifting feel so much smoother. The alloy subframe spacer will compress the subframe bush so you can test them and see if it will fix the problem. Easy to install and pretty cheap. NS Sponsors will send a set out easy.
Cant really comment on the poly urethane type though as i haven't tried them.

[Big Boss]

well i would go with alumimium spacers but since my rear cradle actually moves if i unbolt the subframe the rubber bush will probably just fall out and into about 5 peices. i don't know if you can run them by themselves though

jay, did you do any re inforcing to compensate for the extra stress on the cradle? or how ever it works

also i don't know about these for a daily!

[NRG180]

I've bought and installed a set of urethane pineapples today and I gotta say faaaaak yeaaaaaah!!! So much better now. Feels very sharp and controlled. Highly recommend those. No extra noise or vibrations too. Wish I could try a set of alloy ones to compare.

Very easy install without taking cradle off. It's been covered. But I'll type 180sx drift set-up install in more detail.
U need 12 and 17mm sockets with extensions.
Jack and stands.
Bushes
Optional: T-bolt clamps or zip-ties. Get proper quality items.
Time 20-30m max.

First jack the car and put it on stands. If you have access to hoist even better.
Undo nuts under each 4 mounts with 17 socket. Leave the nuts few threads on.
Rear of the cradle mounts (behind the diff) can be slit to slide in from the side. Pull cradle down a bit and wedge the bush in.
Do the front of the cradle mounts (in front of diff) one at a time. Undo 12 mm bolt and nut and 17mm nut the bottom of the mount comes off. Slam the bush in and everything back together. First 17mm and 12mm nuts then 12mm bolt. Now if the cradle is a little too low for the 17mm nut jack it up a notch near the mount.

Now if you wish a little more rigidity or worry about slit bushes you could put some t-bolt clamps (or even zip-ties) around the bushes and give some tension. I did t-bolts that for mine.

Alloy bushes install is a combination of above two descriptions to each mount. U get the idea. Undo bottom mount, slide c-shape on top, slam the other on under.

Tighten all nut/bolts. Test drive and check.

[Big Boss]

yeah this sounds awesome mate, and thanks heaps for the how to!

i am leaning towards the solid alloy replacement type where you need to remove the whole standard bush and have alloy from chassis to subframe, but i'm worried about flexing you know, if it's going to need re inforcing or something annoying like that

how much were the pineapples? do they just sit on top of your standard bushes?!

[NRG180]

Spacers compress existing bush and limit subframe movement.

Alloy: http://www.nissansil...p...icle&id=278
Urethane: http://www.nissansil...neapple+install

Solid bush is a replacement of old bush. Much harder install. I can guarantee yr car will turn into a vibrator on wheel with those.

Do a search, all three covered in great detail all over the net. Sponsors have spacers from around $50-60 for urethane pineapples and $125 alloy spacers. Solid bushes from about 135 and over.

I get the idea that alloy are much better for handling. Urethane are almost the same but a bit more comfy and less noisy.

[Big Boss]

thank you mate, yeah i bought some C type alloy, hopefully it goes good and solves the problem, i will let you guys know, and i didn't think it would vibrate that much more the the solid replacment? i almost got them, lucky i chickened out

should have an answer by next week early

[NRG180]

I've had mine on those spacers for a week now. Big difference. There are new sound in the car now.

[Big Boss]

okay, i've installed the C types, they're so tight that i can't tighten them anymore, and my subframe STILL moves around, just the same as before, infact i notice no difference at all, i would say it's worse now, becuase i threaded one of the nuts that goes into my chassis, one of the 12mm they are so easy to thread!

so what's going on, i still get axle tramp witch means my rear subframe is still moving around, i still have a loud clunking problem, and i can feal it sway back and forth, all i do is change gears, put the clutch in, CLUNK, let it out, CLUNK..

i don't know what to do from here, is it just because my subframe bushes are so bad, or could it be something to do with the half shafts? or drive shaft even? i know it's not gearbox because you dont get axle tramp from the gearbox

anyone live on the coast who has delt with this before? i'll pick you up and take you for a drive to show you

[Big Boss]

yeah my bushes are torn so the C collars only increase the clunk.

i new this would happen but i guess i can get a replacement and sell the C collars

so now i face a question that i need to get right first try. replacing the bush with, solid alloy, nismo (30% stiffer) or polyurthane and pineapples

only troubles is i don't have money to just test them all out so i need help to know witch one to get, i would love solid alloy to just completely lock the damn thing to the car for ultimate smooth sliding, but could some one take me for a drive in an S13 with them? i don't know how bad NVH will be, i don't want my interior vibrating falling apart as it's my daily.

[J_Spec]

Hey mate so the alloy C bushes didnt work, damn.
could buy full solid alloy replacements, but not sure on the roughness - cant be that bad because it will be attached properly to the chassis of the car and the suspension does the dampening for that. Only thing i could think of would be vibrations from the diff and maybe tiny bit more noise.
or
replacement subframe bushes(poly urethane or rubber, your decision) with the alloy bushes you bought sitting on top if they can fit on for a bit more comfort for daily rather than the full solids.

Subframe will have to come off either way,
The 12 mm nut can be replaced at a fastener,bolt,nut shop.

[NRG180]

That shouldn't be like u say... Subframe still moves on spacers but only about 5mm max. At least mine does on urethane pineapples...

U say the clunk comes with clutch. Could it be clutch itself...? Best way is to do one thing at a time. Progress easiest to hardest.

Or just live with it. Man, there so many noises in my car. That's why ppl drive with music so loud.

[Big Boss]

thanks guys

appreciate the though NRG but i didn't say the clunk comes from the clutch, when i push the clutch in after accelerating, meaning the subframe is being pushed backwards, then you clutch and the subframe moves fowards because you've stopped accelerating and then it goes CLUNK.

you can actualy feel the subframe moving/hopping/clunking there's no doubt it's the subframe, the rubber bushes were fully cracked through, most of them anyway, i think there was 1 that was not fully cracked all the way through

i'm going to be taking the subframe off but i dont care about the work involved, just want to go sliding for HECK sake

everytime we talk about the extra diff whine noises from fully solid replacements i get pretty excited about that jay

and you're right about the suspension acting as dampening so it wouldn't be too harsh. but i don't know, i need some one to take me for a drive in an S13 with solids

[NRG180]

Fair enough.

Stock bushes are filled with silicon and once cracked they are gone.

As an option:
One of the sponsors, D-Project has that OEM stile replacement bush made of vulcanised rubber. That's similar design to Nismo. I heard Project D stuff is very stiff and, even though its rubber, still sends vibrations through to cabin, but still not as harsh as full alloy. And you can use your C-collar with those.

EDIT: Sponsor name DriftShop

[Big Boss]

WOW what! that's awesome.!

i am getting them then.

if you can use C collars i'm happy, i love C collars even with my clunk.

EDIT:

if they were filled with silicone, it would drip out once cracked? i've had the clunk for 2 years now beleive it or not so they are wayyy long gone.

and thank you man, that's pretty much exactly what i'm looking for

There is a few different versions of these... I think the other thread may have been misleading champ? Post up the results though!!!

[Big Boss]

yeah well the other thread was just to ask anyone who uses a solid replacement if they're too harsh, but! with no success there, i just messaged Drift shop and they'll let me know if they have a set ready to go, and i'll get my subframe off asap, get them pressed in and before i add my C collars i'll just test out how it goes without them, then add C collars.

will let you all know how i go, but i'm %100 sure it will solve my issues

thanks to everyone who's been helping me out and putting up with nooby questions!

Err...Why add C collars after the replacement bush? You wont need too

[Big Boss]

for extra smooth sliding

[34GeeTeeTee]

The bushes should do this for you. They are harder than the factory items.

[Big Boss]

well like i said i'll try both and see what i reckon

[Big Boss]

damn i don't know, i am doing alot of extra research before considering, and i've found, C collars are only for when your bushes are starting to wear and you notice it clunking, and solid alloy is too stiff, urethane is so stiff you might as well get alloy and they're way easier to install

a guy doing a build up thread on here is using replacement urethane for the subframe, and then pineapples inbetween them, this is what i've been considering

the plan was to get D shop bush, and run a collar in years to come when they're getting worn

[NRG180]

There will probably still be some movement with replacement bush cos by the looks of it its about the size of stock and stock doesn't sit flush to chassis.

But as Boss said you can chuck on c-collars any time.

[J_Spec]

The C collars with the poly's for that extra bit of stiffness . Its a tough call but think of how you will be using the car and buy the type of bushing to suit it.

[Big Boss]

yeah daily, and slider, you can't run C collars with poly? poly is flat so the C collars can't actually sit anywhere
unless you're talking about some kind of poly i dont know of yet

i've been looking for urethane but no one flippen stocks them.

im just sick of looking by now, D shop is out of stock of there bush, who knows where to get nismo ones or if it's worth it solid is way too hectic everyone's been saying

those are the ones i wanted, but i'm just getting whiteline bushes now because i don't have to wiat 15 days from the US, everyone can get these local, but i can't.. lol sad aye

ah well whiteline it is they're a good name so it should be good i don't care anymore

[Big Boss]

well i'm back again

i have now replaced my subframe bushes with brand new nolethane subframe bushes

i still have the clunk

stil got axle tramp but not as bad.

WHAT THE HELL COULD IT BE I AM GOING TO BURN MY CAR
