Kaaz diff owners inside please
 

hi - just checking that below behavior is normal.
due to clutches locking and unlocking, or something like that.

if you are driving at steady speed like 80 mph and abruptly let go of the throttle, does the car pull to the left? mine does.
is that normal?
getting back on it abruptly makes it pull the other way.
thanks.

Thats not normal, but that sounds like an alignment issue.

My Kaaz is acting up too pretty bad. This is the second unit I've had, the first one whined a lot but never broke. This one makes a horribly loud chattering sound on left and right turns only. According to a good friend of mine who is very knowlegdeable, there is hope that is just has insufficient/incorrect fluid. So first thing tomorrow I will drain and fill it with new Kaaz fluid (I don't understand why they wouldn't fill it properly after it was assembled). If that doesn't work then what is the equivalent of planetaries in the diff. is screwed up. (It wasn't assembled/adjusted right I guess since it's brand new)
It really sounds like it's ready to fail, I hope it's just grabbing because of fluid
:(

The chattering noise is quite normal on slow speed turns when the diff oil is fully warmed up, does this on mine, the noise has gone down over time and I have changed the oil a couple of times as the plates bed in.
Did you do the correct break in procedure?
Mine has been running fine for the last two years with the low speed turn noise.
But it should never pull to one side on decell on high speed runs unless you have a 2 way instead of a 1.5 way which I have heard does this.
As Ernie says maybe an alighment issue for the first poster

FIXED! Thanks to Crispeed, the Rx-7 forum and the Kaaz website. I changed the Kaaz fluid just to be sure it has the correct type and amount. I also added 1 small bottle of the recommended GM limited slip additive (right off the shelf at work :))
Then I did the full break in procedure as per the website:

I did exactly 30 minutes, was dizzy afterwards. The noise has decreased 300% and runs great. Thanks!!!
