Hey, i've got a isuzu bighorn 93 model.. anyone here knows how to determine if its differential has LSD? Physical characteristics? i plan to change the differential gear oil but can't seem to find out which one to get... thanks..

Put wheel chocks/block on front wheels
Jack both rear wheels up
Release parking brake
Spin one wheel
Opposite wheel spins in same direction - LSD
Opposite wheel spins in opposite direction o OPEN Diff

diba iba ung gear oil for LSD diff than a reg diff?

if so saan kaya makakabili ng gear oil for LSD diff?

check mo yung plate sa firewall sa engine bay, the plate with the VIN number, engine number, and chassis number. sa lower part you'll see options with different codes, pag may G80 it means LSD equipped yun

You can buy LSD gear oil or you can buy LSD additive to add to your standard gear oil. Sa SM Ace meron dati nitong LSD additive.

what's the difference (pros and cons) between the LSD and the Open Diff? thanks.

Open Diff
-Transfers power to the wheel with the least traction (imagine L300 backing up a steep driveway in the rain)
-Simple and cheap

LSD
-Still sends some power to wheel on opposite side should one lose traction (I've tried this with a Starex LSD, it works)
-Not as cheap or as simple to produce
-Can become noisy over time
-Excessive use in low traction situations can also 'wear out' the LSD in some vehicles (magiging parang open diff na lang siya)
