My torsen unit has went to crap and now i need a new LSD, it been making a clunking sound in time with the wheels as they spin, faster you go the faster it goes anyone ever hear something like this and do i believe the techs on this one. It has been sitting for over 30 days getting tranny fixed, could it just need the diff fluid changed.

any thoughts

Update on the redline fluid / kaaz diff combo:

I don't like it. The redline fluid just doesn't have enough friction and it lets the inside wheel spin pretty easily. Damn thing almost acts like an open diff sometimes. I'm not sure how much of this is because the clutches are wearing (I've got over 40k miles on the diff), but I'm definitely going to have to change something.

RT, I think you'd like how it drives on the redline fluid.

Anyone know which of the other redline fluids would have a little more bite to it? I guess I can just email them to find out...

Rev, I'll give it a try next time around (I did run the red shock-proof and hated it)....... maybe you should give the Kendall a try since it might actually have more bite than the Redline w/ FM from the sounds of things. I've never had the inside tire spin on me but I don't think I've ever had it off the ground either ;)
Redline makes a brew with the part number ending in "NS" which is basically the stuff you used minus any Friction Modifiers. The intent is for you to add only what you need (they sell the FM separate) so that you can fine tune your sh!t.

Yeah, I actually get wheel lift fairly often with my suspension. I have JIC coilovers with 670 lb springs all around, so my sh!t is pretty damn stiff. The most common situation is when I'm going in/out of driveways sideways to avoid scraping, one of the rears will lift off the ground (basically, the car will teeter-totter on diagonal wheels). When I start to apply power, the lifted wheel will spin, then the clutches will catch and the car will lurch (or the lifted wheel will touch down and do a mini-one-wheeler-peeler). It also happens on canyon roads when the turns have pretty heavy banking.

Anyway, I wrote to redline, I'll let you know what they say. I'm actually interested in the shockproof oil because it's supposed to help reduce temps. I don't know exactly what temps my diff runs, but it's hot enough to cook the crap out of Kaaz fluid, so I assume that's hotter than it should be. If that doesn't work out, I'll probably just buy the NS fluid and add the friction modifier sparingly. My goal is to get a fiar amount of lockup at track temps, but not so much that the car is constantly fighting me in parking lots and becomes a bear in the rain.

i just installed a cusco RS 2way lsd and damn does that thing chatter. right now it just has honda gear oil in it. i want to wait till about 1k miles on it before i change. or do you think i should go a little earlier? i am trying to locate someon who can get me the cusco diff oil but so far no luck what so ever. if i can't find the cusco oil i don't know what to go with. i used the redline in the stock diff and didn't like it at all, the shock proof was horrible. especially on cold starts.

You need to use a fluid with friction modifiers. Your cusco unit is a clutch-pack unit (like a Kaaz). This is not the same as the stock Honda unit and has different requirements. If you're having lots of chatter, just use the redline stuff and that will cure it. If it still chatters, you can add more friction modifier. what didn't you like about the redline fluid on the stock diff? How could you even tell a difference? I would think it would make almost no difference on a gear-type diff. And what about the shock-proof? That I could see as having more effect on a stock diff, but you say it was "horrible." Can you elaborate?

horrible meaning when i would start the car after it had been sitting all night, the diff didn't feel like it was working right. it felt like it didn't have enough lube right when the car would start moving. i had a lot of vibration and rough driving. once i has been driving for a good amount of time and got heat into the diff it was ok .
