Is it louder when you turn right ?
I got the same problem I have the Y1 LSD tranny with Y1 interimediate shaft, and Hasport Y1 axles with Avid engine mount. It's still cluncking and I still driving it. the problem is the Axles that a bit too long, causes the joint inside the axles cannot turning when you turn the steering wheel but doing ok when you go straight, Specially with the passenger side axles. My friend he done some mickey mouse job by grinding a little bit inside the axles where the inboard joint gonna attached to. It doesn't make noise as before, and only make noise when start running, and not make noise after I ran on the freeway. My friend suggestion is ask hasport maybe they send wrong axles, or make custom made one. I lost my box, thats why I cannot ask hasport no more.

To add to this, if it is the same problem I'm having, its not clicking. Its not like when you turn it clicks. It clunks, and clunks hard. It pulls and releases when you turn. I do believe there is clicking in the axles but there's no way axles/cv joints could cause play in the steering wheel like that. I will swap out my cheap *** axles eventually and will prob swap out the midshaft as well. If someone actually knows or has a better solution then what has been mentioned, it would be greatly appreciated

I have a y1 with lsd on my gsr in a crx and I have no clunking noises when I turn at low speed or high speed.

my brother has a eg with type r lsd and his does the same thing as the op when going around corners it clunks we changed the tranny fluid with honda mtf lsd and it went away

I had the same harsh clunking with my y1 lsd. I tried three sets of axles and the problem did not go away. Bought custom axles from raxles, same problem. Changed the oem clutch lsd to quaife lsd and the problem was gone. The factory clutch lsd was junk.

go faster around corners or learn to not accelerate around them at low speeds. end of discussion. problem solved.

I had a similar problem and it turned out to be a bad LSD. The problem was at all speeds and even during very slight turns. Eliminated the LSD and over 10,000 miles later there has been no problem at all. The thread in my signature has more info.

Because all of this matters in parking lots... you add nothing to this conversation

CRseXxy

really what kinda advice is that?

So... in some form of summary, the possible problems could be (as posted by all others)

1) The CV Joints (Replacement)
2) Bad axles / Axles too long (Replace / Grind-down)
3) Some clunking is normal in Clutch-style LSD's (Get used to it)
4) Midshaft issue (Replacement)
5) LSD Transmission additive needed (Drain and Fill) (which didn't work for me)
6) Bad Differential (Replacement) (Which I am starting to lean toward in my "clunking" application)
7) ?

(all of this assuming the clunking is not affiliated with the motor mounts or suspension)

As a newbie (who just finished a Del Sol GSR swap), How difficult/time consuming is it to swap the limited slip differential in the transmission?

EDIT: I may not have given the additive a chance, this is the second day and the noise is nearly gone. I still feel it occasionally but I will give it more time before coming to conclusions. I still don't believe that the additive is required, but it may help more used LSD's, maybe.

From my experience. I have a JDM B16a that came with the JDM S1 tranny. When I bought the car it had bad axles but wasn't clicking. Eventually they began to click then clunk.

I replaced them both, the clunking continued. I believe within 3-8 months, which it shouldn't have been that long maximum, the clunk noise went away. The 3rd/4th shift fork in my S1 tranny started to thin out and cause my 3rd/4th synchronizer on the 4th side to go bad. No 4th gear. I had to swap it with a temporary LS transmission and used the same axles. No clunking noise.

1 year and 6 months, I had to replace both axles again. The clunking noise is back. I'm going to le tit clunk till it goes away which is probably bad for the axles itself.

Its more harsh clunking on the passenger than the drivers side axle.

You got to put the obvious before getting technical here. EF's with engine swaps (bigger). On top of that, if any of ya fell'as have your car lowered as well, that adds on to your clunking noise (being the axles under stress).

Its not like these engines with their transmissions are in their regular cars they were meant to be in. I'm sure US modified these EF's a tad bit for them SOHC's unlike japan who regularly modded the cars to withstand this stress.

I know I need a bushing kit, and my inner tie rod ends need replacing again after I just replaced them 2 years ago as well.

I baby my car.

I'm hoping it is the axles, which it mostly likely is.

im looking at buying a car. the guy sais its doing this exact same thing..loud clunking noises when turning and such and such...he sais its a carbonetics LSD and mentioned something about a Detroit Locker. and that its for circuit racing or something and that its supposed to lock up under heavy use but he states that its constantly "clunking" under regular driving conditions. Im planning on calling the local performance shop to investigate but wondering if anyone here knew.

also found this: which kind of supports it.
http://www.motivegear.com/MotiveWeb/...etroitinfo.htm
supposedly the "clunking" is..
"Driver may hear and feel "backlash" going from drive-to-coast and coast-to-drive, as reversing torque flow resets the components."

Wow, thread is 6 years old and no post for a year now. Check the dates next time. Start your own thread.

advtactics01

well..ill admit i didnt check the dates..but i didnt find any other "current" thread covering this and this thread didnt really offer any solid answer..soo..thanks for being a jerk..and your welcome for using the search. a couple others came up under "carbonetics lsd" but thought this was the one most direct to the issue i am having.

it seems to be a pretty popular thing to nag a new user for starting a new thread before checking results..i figure this way im keeping the site clean. your welcome

Simkin314

Just be wary of 1) buying a vehicle is questionable driving condition and 2) trusting the seller to his word... It sounds to me that the guy is selling a tired car so, Make sure you have a plan B just in case (like having an extra transmission laying around, shop for a new differential, etc).

As a '2 cent' note (and I am likely to be in the minority), your linked information seems relevant to the thread topic and adding such helps future thread searches and topic understanding. These old threads build thousands of hits through the years, the more information included, the more likely it helps someone later down the line.

Worn engine mounts??????????

advtactics01

hey i appreciate the support...
it may be that its a tired car..he also stated that he replaced the axles for fear that THEY were the culprit. He also sais he has reciepts showing he had the tranny inspected and passed. I know shop fees are pretty expensive to take out and re install tranny's so it sound like the only way hes getting his car sold is by outright lying or lowering the price (from 7k)

advtactics01

alright everyone..i just got off the phone with the local motor sports co. here in my town...they stated that this problem with frequently arise with Clutch Plate type LSD's. He said they typically last between 30k to 40k miles. When they starting going out they make a loud "clunking" noise.

Also he strongly encourages the use of Helical type LSD's in regular street driving (non racing) because they essentially won't break as long as maintenance is kept.

He also states that if the fluid is replaced with the wrong kind..it will fry the LSD.

Sounds like you have a very aggressive type lsd, Mine is the same way I replaced the gear oil with some honda mtf and added some additive called "ford modifier" it did the trick for me.

Jaime 91SiB18

It sounds like you have "clutch-type" LSD and the clutch packs are worn out. What you feel is the rivits catching when the LSD should be slipping.
I had the same problem with my YS1 LSD. It is now sitting in my garage due to a lack of replacment clutch packs.

I had this same problem years ago in a crx I owned at the time. Previous owner claimed it had a Cusco LSD. Would clunk embarrassly loud while turning at low speeds, definately not cv joints. On a trip through the Arizona desert, in the middle of summer, I got a flat. Threw on the spare and was on my way. Appearently the difference in size, wieght of the spare compared to my other front wheel totally ****ed the lsd. 40 miles outside of Tucson my tranny began to lock up on the freeway... until eventually I could not keep freeway speed and had to pull over. **** was a nightmare. Ended up getting a big *** LS tranny, but at least it didnt clunk. End story.

u need a new version of the half shaft hooked to engine jdm one is a little bit longer and will cause axle grind and make noise u can make axle that will fix but easyer to change half shaft from a 99 civic si one

chambersef8

Dude, it's not axle grind or the half shaft. The loud clunking is a fuked diff.

advtactics01

two different performance shops said that if the LSD is making a LOUD clunking noise..it needs to be replaced.. they said if you have the wrong oil in it....race it..it is done..REGARDLESS if you replace the oil afterwards...

jsilva8eg

i got an eg hatch. h22a4. quaife lsd. my car does the same thing, also only under gas. feels like the car is locking up when i turn. normal? not normal? some one find out !
