Does my LSD sound normal? (video inside)
Someone told me this sounded normal to them, but I have my doubts about their mechanical skills. And it seems like it's just too bizarre and loud.
I've had quite a few axles go bad on me. They're crap autozone axles, but that's what I have. Anyway, what happens is I'll be driving down the freeway and either gas it or drop it into 4th and then I'll get a wicked vibration and a weird scraping noise. This happened to me today on the way to work, so I pull over and check everything out and all seems well. I pull out onto the freeway and get mild vibration only while under throttle, I can let off the gas and it goes away. I'm saving for a set of raxles atm so they'll be on shortly.
So when I get home from work I get under the car to check out the axles and see if I can spy any play or looseness that shouldn't be there. The axles seem ok, but when I rotate the tire with my hand back and forth, the diff makes a really odd sound. Kind of a clunking like there is a bunch of rocks in there or something. There is some play as well, I don't know if it's just how LSD's sound or if mine is going out or what. Anyway, I made a short vid of the sounds. I know sound vids suck, but I wanted to get your input on it.
Thanks, here's the vid:

Man, I watched it again and it really sounds like there is a bag of rocks where my diff is.

i to own a lsd tranny, and when i listen to your video, that deosn't sound right.
there should be no noise coming from the tranny, let alone a clanking noise like that.
i would take it to a shop and have them take it apart. have you been taking some tight corners? when you lower the car after having it jacked up, do you release the jack slow? it doesn't take much to break a gear type lsd.

I haven't been doing too much hard turning this year, but last year I did and it sounded like that before then. When I lower it, I do it real careful. Are you talking about like a transmission shop?

a tranny shop, or a really honda mechanic. and if you say it was like that last year, did you ever think hmotorsonline sold you the tranny like that.

I'm pretty sure it was like that when I got it, but I don't remember for sure. Would launching hard or shifting from say 1st to 2nd hard be enough to break it? I's run like that for a while.

no shifting hard wouldn't break it, not sure if you miss gears or grind into gears.
the car slamming would usually cause them to break. who knew what type of driver the previous owner was.

ΖΛΚ says (2:43 PM):
Watch this vid and tell me if this sounds normal for an LSD diff
I'm laying on my back and rotating the tire as it's up on jackstands
Nny says (2:44 PM):
Is it rotating in a constant direction or back and forth?
ΖΛΚ says (2:44 PM):
back and forth
Nny says (2:44 PM):
fairly normal
ΖΛΚ says (2:45 PM):
Ok, I'm just trying to figure out if it's my axles or my tranny before I go and drop a chunk of money on something that won't fix it
Nny says (2:45 PM):
Can you hear it under normal driving?
ΖΛΚ says (2:46 PM):
No
ΖΛΚ says (2:48 PM):
Any honda people you know who might be able to listen to that?
Nny says (2:48 PM):
When spinning it back and forth, you have to consider your ring and pinion lash is going to allow the gears to move back and forth before the LSD will lock up.
ΖΛΚ says (2:49 PM):
I had someone say that to me once, but I didn't (still don't) fully understand exactly what that means but it makes sense.
Nny says (2:51 PM):
You have two gears that mesh together, which is typically the power from the transmission changing directions to go to the axles. THere is space between the gears, also known as lash.
If there is space, there is movement. If you change directions each time, you are moving the gears across that space until they contact on the other side of the tooth.
ΖΛΚ says (3:00 PM):
Oh ok
thanks for explaining that to me.
Nny says (3:01 PM):
If it is noisy while driving, then your lash is out of whack or your fluid is bad. If it is noisy under wheelslip, then it might be the lsd.

yeah, something is wrong with your tranny, not sure what, but there is something.
like i said earlier, i too have a lsd tranny and mine doesn not make that noise.
now, i do get a clunking noise only, and i mean only if i out my hands on the tires and give quick short spins back and forth. and even then you can barely hear the noise.
but watching your video, i noticed you were spinning it in one direction consant, and you still had that heavy clanking noise. lsd is not supposed to sound like that.
i know money can be a issue when it comes to stuff like this, so why not start w/ the cheapest way. change out the tranny fluid and see what happens. make sure you use Honda MTF.

i dont think theres anything wrong with that.
1. u have the car in the air and are spining your wheel clockwise and counterclockwise. and judging by the vid ur doing it a lil quick it sounds like. dont forget you have an lsd so if you turn the wheel a quarter of the way and then slam it in the other direction that noise is going to happen. u have an lsd u turn the wheel u have to give it a lil bit more than a quarter turn for everything to mesh and engage.
2. all of the itr tranny's i have had have done the same thing in the air.
3. drain your tranny fluid and see if you have a weird burnt smell or if u have some chunks of gear in there and if u do than u know what your problem is.
i have had 3 98 spec itr trannys with the oem clutch type lsd and they have all made that noise. one of them was brand new from honda too.

yes i agree it will make a noise giving them 1/4 turns back and forth, but maybe i'm missing something looking at the video, but i could have sworn he was only turning it in one direction. like i said, just going off of what i have. i have spun my wheels many times (in one direction) searching for brake noises and such, i never ever heard such a loud clanking noise like the OP is hearing.
now, i do have to mention this, being that you have had 3 98 ITR spec trannys, then you should know that they do not have a clutch type lsd, right?

I know it looked like I was going in a single direction in the vid, but I was in fact going back and forth.

then if that is the case, it does sound normal. sorry for the misunderstanding (on my part).
if you still have the vibration, maybe motor mounts? have you checked them?

Re: (philosofy1)
I haven't checked them, but I'm pretty sure it's the axles. I was driving down the freeway when I dropped it into 4th from 5th and let out the clutch I heard a pop and then a grinding sound then wicked vibration. Like steering wheel shaking so bad my eyes were going to pop out! So I pulled over and checked to make sure my freakin wheel was still attached, and when I started off, I now have a constant vibration under throttle and a noise that can only be explained like having flat spots on a skateboard.
I got under my car today because my traction bars were loose and it looks like they're not the same length. One seems to have more threads coming out than the other, and is about 1/4 inch longer. I tightened them up and made them equal length. Think that could be causing my axles to go bad? I never drag race, so I should just take them off.
