These differentials seem to have come in a few different Toyotas. Combos for 4.88s we’ve seen are:
‘92-‘95 4Runner, IFS, V6, 31” tires, auto transmission, tow package
‘92-‘95 pickup, IFS, V6, 31” tires, auto transmission, tow package
The vehicle will also usually have:
door tag code of G144
white pinion paint code - the end of the pinion (driveshaft removed) will have paint on it
It seems that these are the most common combos, but there are also reports of non-tow equipped vehicles having 4.88s. Never hurts to check!
