my ats 1.5way lsd is sheering off the axle splines on the passenger side and causing the axle to pop out, even under street driving conditions (turning) and obviously more often at the track. change the lsd oil regularly, and it seems to be functioning fine other than sheering the splines. anyone have an idea what might be causing this or have heard it happening before+

Before you start some huge debate or any finger pointing or an ATS rag session please contact who sold it to you, or Yasu or Chris (aka rodney here on HT) them selves.

Nothing against you, I just don't want this to sour and misinformation to be passed.

Best of luck,

I agree, a lot of people will go "oh no, I can't get an ATS now!" ATS is a company and they make quality parts. ATS is awsome in my book and I agree Yasu will be able to make it right if you have any problems.

 

in no way pointing fingers or blaming the product. i love the way the lsd performs on the track and highly recommend ats products in general. i have contacted ats japan and didnt get much to go on as far as finding the source of the problem. just seeing if anyone has heard of this on that side of the pond or if its possibly user (me) error.

ok, first question: do you have the retaining ring (c clip) on the inside of the axle? if that ring is not there, the axle will walk out of the diff, allowing only half or less amount of splines to be in contact with the diff, basically putting mucho stress on them. secondly, what axles are thses? did you install a damaged axle, only to damage the diff spline now also? thirdly, who installed the diff? was it shimmed to proper spec? thanks. i love my ATS diff, and will not change it for the world. this is the first i have ever heard of these problems, and i have run these diff for years.

ATS is a company

ditto

 

1. yes the c-clip was on both axles that broke.
2. there were two sets of axles used, both undamaged as far as i know before we installed them.
3. we installed the diff and it was all done to proper spec.

i love the lsd as well and want to keep on using it, just want to pin point the source of the problem so i can fix it. here is a link to some of the pics if you are interested. anything else that might cause this?

thanks alot

Did you use new c-clips or re-tension the old ones?

Maybe the diff carrier doesn't have deep enough grooves for those clips to seat in...

 

the c-clips where not brand new. i guess i will look into that possibility more.

and just for an update, i have contacted both ats japan and ats usa, both say that the lsd did not cause the damage to the axles. any ideas on what could cause this to happen?

 

if the axles were popping out of the diff, i honestly think the axles were not seated fully on install. are you from california? would you be the one that ran honda mtf in the tranny with the ATS diff?

 

went thru two sets of axles. pretty sure they were fully seated. maybe that might be the problem. yes i am originally from CA, ATS fluid only since the diff has been installed.

 

This is the car:

This is the car pitting in when the axle popped out the first time (8 hour Endurance race).

the reason i ask about the seating, is because if they were not seated with the first install of the diff, there would be unnecessary stress on the splines (both the axle and the diff) and could have damaged the diff splines, thereforenot fully seating with the splines of the new axle. when you say the axles pop out, you lose fluid? the car stops moving? please describe, and pics of the axles and inside of the diff would be very helpfull. thanks.

 

i understand your reasoning about seating the axle properly and it makes alot of sense. and hopefully is the culprit.

what happened was under turning the axle slides out of the differential, not completely, but enough that it is noticable and kinda scarry going thru turns. no fluid is lost tho, since it is still partially in the diff. the car will keep going tho. i linked pics of the axles on my previous post. so u can see the damage. dont have pics of the diff right now, but i will try to get those soon.

thanks alot for the help, really appreciate u taking the time to discuss this with me.
