2> I have to be able to pick it up today/tomorrow AM
3> it' cant cost like eleventybillion dollars

 

I always thourght for those LSDs you just found something with out friction modifiers...

 

if you get something w/o friction modifiers you have to then add them in. I think both GM and Ford offer friction modifier.

 

I can get Redline 75W90 Gear Oil with Limited-Slip Differential Friction-Modifier

$11/qt
winner?

 

I thought the friction modifiers screw the clutch surfaces up. Or am i getting confused with motorcycles?

 

looks like a typical 80w90 is reccomended.

 

Call your local auto store, my local Pep Boys carries Royal Purple 75W90 (not sure if it's the friction modifiers added one though, if you need them) for ~$9 and no shipping.

 

sweet, Royal Purple will work, plus I get a small discount at pep boys AND they'll deliver
next hustler-esq question: how much do I need?

 

two of them, the big ones.

 

mmm... my owner's manual says .65 Liter for my 1.6 diff. Can't see a 1.8 diff being that much bigger

 

are they overnighted from japan.

 

whatever,
ordered a 1 qt bottle of the Royal Purple 75W90

Thanks Tom

 

more than you can afford, pal.

 

wtf are you talking about.

one, you hardly need any diff fluid. two, you're spitting out nonsense.

 

He's way too fast and way too furious for us

Got my name on the head rest- read it and weep

they banned me from the tracks for life.



I've never actually seen that movie, but its so much fun to quote.

 

seriously, you're about to get gagged in about 2 minutes.

 

I use Royal Purple In all my vehicles diffs. and so far it's worked flawlessly. I believe Royal Purple also has the friction modifier in it. It's funny, I have 6 quarts or Royal Purple sitting in my garage right now. I'm going to change the front and rear diff oil in my 86 trooper one day.

 

what fluid for a new kaaz lsd? use the supplied kaaz fluid for the break-in or should i break it in with some cheap fluid and put in the kaaz fluid afterwards?

 

Fluid capacity for a 1.8L diff is 1 liter but I can never get more than 0.8-0.9 liters before it starts coming out the overfill hole and yes, the car is level.
