No such thing, with proper maintenance they should simply continue to work.

It's the clutch pack inside the carrier that gets worn out, instead of spider gears the Mitsu LSD has a clutch pack. If you don't flush an LSD diff out regularly the "crud" in the oil gets in the clutches and increases wear dramatically. The crud also increases slip (also increasing wear) which will decrease the effect of the LSD in the first place.

For LSD swap i've found this from mightyram.net

All trucks 79-96 came with what Mitsubishi would call a 8inch differential in the rear


GEAR RATIOS
D50/MMs came with 3 different possible gearing options
3.545 used in certain 2wd trucks let you achieve optimal fuel mileage
3.909 most common gear ratio used in about our trucks most 4x4 came with them for sure
4.222 rarely seen in the D50/MMs only seen so far in 4x4s so far primarily seen in Dodge Raiders/Mitsubishi Monteros
4.625 never came in the trucks only seen in the Monteros/Raiders swaps into our housings

LIMITED SLIP DIFFERENTIALS & IDENTIFICATIONS OF THEM
LSDs or different gears can be swapped out of various vehicle depending upon wich diff you have if you have the 7.5in diff a rear diff
out of any FOUR CYLINDER MM/D50, Montero/Raider will work

If you have a LSD factory you will have an orange sticker in the door jam and on the differential housing its self talking about the use of LSD additive inside of that housing If you cant find those stickers but still wanting to make sure you do or dont have an LSD you can jack the back of your truck up and spin one wheel then watch the other side to see if it spins in the same direction

Now if you have a 4x4 MM/D50 the rear differential out of a Starion/Conquest will work Starions 1983-1987 (1986/87 widebodies all came LSD, narrowbodies with LSD are more rare) used a 7.5" diff, which will work in the FRONT of a 4cyl truck/rig. Starions 1988-1989 used a 8.0" diff, which will work in the FRONT of a V6 truck/rig. (thanks Robert) If you have a V6 powered truck any first gen Montero/Raider with a V6 will change differentials with your trucks 2nd generation Monteros wont work with the 8in housing available in our trucks I was told the Monteros have a high pinion design compared to the trucks low pinion design





The Starion LSD from years 83-87 will fit the front diff of the 4cyl MM/D50 trucks/Monteros.
The Starion LSD from years 88-89 will fit the front diff of the 6Cyl MM/D50 trucks/Monteros.

The Montero LSD from 83-89 4Cyl will fit the 4cyl MM/D50 trucks rear diff.
The Montero LSD from 89-91 6Cyl will fit the 6cyl MM/D50 trucks rear diff.

Not all early Starions had LSD, special order and 85.5.
All widebody Starions had LSD.
Not all Montero's had LSD, check for orange sticker inside drivers door jamb.

I think that this is good for Delica.

On Strada,and probably on StarWagon with manual transmission,the gear ratio is 4,625:1
On a SpaceGear with automatic transmission,it's 4,875:1.
I don't know for manual transmission.

I currently have open/open diffs. a locker is way more than what I need(pricey too) since I don't 4x4 hard at all. mainly FSR's with a little interesting stuff here and there to get to those elusive camping spots and fishing holes.

should I try to find a cheap one?

thanks
IMHO, If you're already going through the trouble to find and install an LSD, why not spend a few hundred(or thousand) more in installing a selectable locker?

It really depends how sticky of fishing holes you're getting into, but for myself, when I am fishing alone I would rather have the added comfort of knowing I can get through the sticky stuff. Weather changes quick snowing you in, heavier rains causing water/mud holes, easier to go down than back up, etc etc. So if traction is your concern, I would go with a selectable locker as the budget allows.

Or better yet, I would forget both and just buy a decent winch and bumper. That way you get the peace of mind having the winch for yourself or others for when you really need it, you have your bambi bars for the night time drives home, and you have better towpoints and armor if you hit the ditch. I mean really, if you really get in shit the recovery, tow home, and drinks for the boys is going to be as much (even more) than a winch. Use it more than once and the bumper was free!

Awesome info..thx strada92.

And I have actually just bought myself a winch, this summer will hopefully involve a bumper designing/building project.
