so whats the deal with this LSD mod ive heard about?
its almost doubles the slip torque(still not sure what that means but have an idea)
whats required?
how is it done?
have any of you done it?

i think it has something to do with tighter clutch packs in the diff. requiring more torque to break it. or i could be totally wrong (most likely).

thats what i was thinking

It's true, and it's been done by a few people. It involves using clutch discs from earlier model LSD's and repacking your clutchpack in a different order. I haven't done it, but I'll see if I can find a link somewhere.

Quote from XOC:
"The factory spec for the 2000 Xterra h233b is 138-180 ft-lbs. of torque needed to make it slip. The 95 Pathfinder with an H233b LSD has a 260-289 ft-lb. breakaway.
The 2001 and 2002 Xterra have the same 138-180 ft-lb. spec. However, the 2003 and 2004 have a PATHETIC 29-43 ft-lb. breakaway torque. That's essentially useless, why even bother..."

"It is possible to modify the performance of the LSD by adding extra discs to the clutch packs at $25-30 a disc, 2-4 discs should do the trick depending on how worn the existing ones are among other things...This isn't a job for someone not comfortable with more than casual hands-on work, and there is a lot to go wrong if you screw up, but it's really not all that complicated."


And HERE is the link to the basic HOW - TO. (http://mywebpages.comcast.net/xterra/tech/LSD/)

omfg i want to do that!!

X2 i wouldnt mind doing it also......... just need to find the extra money.... LOL

hope one of you dudes can answer this..

if i didnt want to open up my diff and rather by the rear end off a 95 pathy, would it bolt right up? would i have to change gears? would i have to worry about anything else?

wouldn't it be easier to just replace/add those clutch packs?

Nope. Different gear ratios, and they used 31 spline axles, not 33. Plus they used different brakes...

So, it's not worth it... You'd have to change the whole rear axle assembly, modify the braking system, and match the front diff to the rear gear ratio.

I THINK im just gonna buy this 78 cj5 off this guy for less than $1k, it needs a wire harness

what would that entail work wise?

what would that entail work wise?
the jeep? i dont know, i havent even seen it yet, wont get to til may when i get back from the honey moon.

ps im getting hitched saturday, like 4/21 saturday, then going on a cruise til 4/29

yep right now ricer is headed to lousiana so he can get married

not to mention you would have to weld some spring perches on.

this is confusing to me...

138-180 ft-lbs. of torque needed to make it slip, does that mean 138-180tq needs to make it to the rear wheels to make the LSD slip??? Axles is something I have never gotten into before, I have bough and swapped when someone posts get this one its the best for you, but never built myself...

You are correct. Once the torque/resistance to the wheels reaches a preset limit, the differential will disengage and become an open diff again.

Some have higher limits than other brand/style LSD's but I'm not sure if there are all that many options for the X. Go figure...

Ok so with the 95 Pathfinder with an H233b LSD has a 260-289 ft-lb. breakaway torque, how does that work when the X produces less then 260tq?? Does it have to do with gear ratios??

Possibly. That part I'm not familiar with. With increased resistance to the wheels, it may increase the pressure against the diff which could break it loose. No idea really.

Just dump a G in ARB and slap an air-locker on it. lol

Remember, that even though the engine produces X amount of torque, you're doubling/trippling/etc. through the gear ratios in the transmission, transfer case and diff gears. Horsepower and torque are generally measured at the engine. When they're measured at the rear wheels, it's typically in the transmission's 1:1 ratio (usually 4th in a manual, 3rd in an auto).

The breakaway necessary to get the LSD to slip is the torque needed to loose the ability to spin both wheel equally. If the vehicle is stuck, the LSD will hold up to said torque to move both wheels. After that, the LSD will slip and the wheel with the least traction will get the power, just like an open diff.

So, if you're stuck in the muck, in 1st gear, 4 low with 4:63 gears and you dump the clutch to get it to move, the LSD will most likely slip and the wheel with the least traction will sling muck everywhere. Now, if the breakaway torque was higher, and you ease into the throttle, then possibly both wheels will spin and get you out.

RicerX, I have a Pathy 31 spline LSD that I can repack for you, if'n you want. I can actually go through it and give it the correct thickness, not just spool it up (superpack) like most want.

So, has anyone done this yet? I think it's rediculaous that the X's have such a low torque break. With the amount of wheelin that I plan on doing, I think that it would be worth looking at or would it be better to get a locker for my rig? This opens a whole new arena for me, THANKS ALOT!:aufkopfhauen-big:

Go with a full locker IMO. Expensive as hell but if you plan on really wheeling your vehicle, it will be worth it plus it opens up options for trailside repairs that normally you wouldn't be able to do, that is if you go with a full OBA setup similar to what Kyle has.

Damned if I do, damned if I don't. I might as well. My wife might divorse me, then again, I won't have enough money to get divorsed! So, correct me if I'm wrong, the 04 X has a 31 spline, right? So now the question is do I run the OBA or just go w/ the mechanical locker? The OAB system costs an ass load and the mechanicals are mid of the road. What other advantages does the OAB have over the mechanical lockers? Trying to justify the costs.

Mechanical unfortunately isn't an option for us. The ONLY locker that will work on our rigs is the ARB air-locker.

What's this then?

The X's rear axle is a 33-spline IIRC and this is only for a 31-spline which is usually found in the hardbody trucks and older pathfinders.
