car- 98 ek hatch w/ b16a and y21 trans, kazz lsd, 98 gsr axles. falken azenis.

just bought this car and changed axles. going around corners, you can hear a loud pop and it can be felt in the steering wheel too. the sharper the corner, the louder it is. giving it more gas around corners, its not so loud. after changing the axles and taking it for a test drive, the axles stayed in place and did not pop out. is this normal operation for a kazz lsd? are these the correct axles? can anyone give me any suggestions? any help would be greatly appreciated.
thanks

Yes. Just make sure you're running the appropriate transmission fluid. It should be something that contains a friction modifier for use with clutch-pack differentials.

 

I was under the impression that you did not want to run a trans fluid that contains a friction modifier for clutch-pack LSDs?

&lt;----has to run an open-diff so this is all unknown to me

 

The brand-specific oils such as Kaaz and ATS have already added the modifier. Anyone who has used them before knows they have a very distinct chemical smell to them. This is due to the modifier.

The only issue with trying to blend your own is that you would be guessing at the correct ratio.

Like the vast majority of people, I really don't understand the technology of oil. I do what I'm told or follow the age-old wisdom of if it's more expensive it much be better.

 

i heard that a bottle of GM lsd additive and filling the rest with 85-90w would work with a kazz lsd. has anyone ever used this combination? or does anyone know any other fluids that will also work with the kazz lsd? to tell you the truth, i hate this lsd. id only recommend this lsd for drag racing. daily driving on this lsd and turning makes the axles pop and clunk. thinkin about getting rid of it.

It's the differential itself making noise, not the axles. You're right though... I wouldn't recommend this type of differential for most daily drivers either. If nothing else, maybe you learned to do a little more research before your next purchase.

 

I do understand that the LSD can be the cause but, what about axle lengths? Are they correct? Just trying to source out the problem. Incorrect axle length will cause binding and also make a popping sound under light acceleration.

 

thats what i was thinking too. just trying to make sure these are the right axles. if i leave the car in neutral and let it "roll" around the corner. it doesnt clunk. gonna raise the ride height an inch tomorrow. see if that helps.

bwah.

Jeff is a funny.

 

i have the same problem too. Its hella annoying! is that all that u can do to help the popping noise?

 

It is called LSD Chatter, and is caused by the clutches not smoothly slipping.

Did you break in your LSD properly by following the manufacturer's suggestion? Which LSD do you have?

Also you need to run a transmission fluid with a friction modifier, which allows the clutches to slip properly. THe problem is though that the KAAZ, ATS fluids are too thick for our Honda transmissions, and the synchros end up paying the price. The fluid I use now is a lightweight Redline with a Redline LSD friction modifier.

If you aren't running a clutch-type LSD (i.e. Kaaz, ATS, Spoon, Cusco, Gripper) you're probably hearing CV noise which is totally different.

 

I do not have experience with clutch LSD's so I would listen to everyone about that possibility. If the axles are not correct (wrong length or whatever) you should hear a noise either all the time, or all the time when turning. The noise may get louder/quieter depending on speed/load, but it should always be there. If the noise is actually going away (not just getting drowned out) with speed/load, then the axles are not the problem.

I broke in my Kaaz per directions, but it always chattered making parking-lot / paddock maneuvers.

If your fluid doesn't have friction modifier, get some from GM/Ford/Autozone. Or switch out to a fluid with the stuff in it.

If you stop using the FM, the clutches will grab harder, but also chatter. If your LSD is worn out, getting rid of the FM helps a little.

 

i had the same problem with my Kaaz LSD... i contacted Kaaz and this is what they said to do......

Hi Josh,
Thanks for your inquiry.
Please make sure the axles are securely locked inside the diff. Sometimes
the shimming on the lsd while installation could be off and the clip may not
be expanding full when the axle is installed. This may cause the axle to pop
out easily since the snap ring is not fully expanded to lock the axle in
place.
Next scenario: The passenger side axle could have had excessive play and
caused the side gear inside the diff to wear out internally where the snap
ring locks in.

The best cure for this is to swap out the right and left side side gear (the
gear that axle goes through) inside the diff.
This process has cured many of this axle pop out problem. Just swap the
right to left and left one to the right side.

Best Regards,
Ray / Kaaz USA

i pulled my tranny apart and went though it checking everything they told me to check.. put it all back together and back in the car.. never had a problem again!!!!
