there are some advantages to ACD, especially now that it can be programmed, and can work well in conjunction with a rear diff. in the end though, i doubt you're losing much

got a question for you guys - it's not the rear diff, but in normal driving on very tight turns i notice that my inside front tire spins - the trans and t-case were built by shep last year but i'm not sure they touched the front lsd. thoughts?

Like when turning right from a stop light? I guess I'm having trouble picturing a scenario in normal driving where you would be accellerating hard out of a very tight turn.

The normal front diff (sometimes called the RS diff) is a helical style and there is nothing a shop can do to make it "work" any better. There are a few things that can be done to make it stronger, though. If you get near 100% weight transfer and your inside front tire does not have much traction, then the helical diff basically acts as an open diff and your inside front tire will start to spin. I don't see how you could really be doing this in "normal" driving, though . . .

normal driving - literally at a stop light, pulling out of driveway, etc, 90 degree turn, or like a u-turn, i can hear the tire sh-sh-sh-sh on the road. not EVERY time though, but that's why i'm wondering if it's broken. don't need to really be accelerating a lot for it to happen

Are you sure it's the front tires? Sounds like the rear binding up from the stiff diff. Seems normal for a tight rear diff on slow tight corners.

^ this.

Kyoo. When you car is cold. Make the corner you're talking about and pay attention to what it sounds like.

Then go drive a few miles on the freeway and make a similar turn.

Sound different?

If so it's your rear diff.

Nice! thanks alot... I'd rather sell my 03 and get an 05+ if it were a really big advantage but if these 2 combos work then I see no point in wasting time/money

Questions is--for those using the daiqueen, does the car get a slight vibration ie jitter around corners as the clutches slip at low speed around corners or does this go away with oem--? Just those who know for a fact pls. Have to buy diaqueen by the gallon, and its too expensive to guess.
For those that care-- Finally just bought Diaqueen and just put it in this morning. Took it for a spin-- So, this is the stuff, No other additives. No jittering around corners no other noise, a lot less noise on deceleration-- Just what I was looking for. Now, I like Amsoil and have used it everywhere--have to say that nothing comapres to OEM with the clutch job done on the rear end though.

Glad you got it sorted out. I agree, Diaqueen is good stuff for the street.

I found a video that gives a really good demonstration of how well TRE's diff works... hope this isn't a repost. http://vimeo.com/6554681

It looks like the car is just being brutally man-handled and there is still bad understeer. Hard to tell really when someone drives like that - yuk!
