3 bolt lsd?

[MellowVR4]

How can i tell if the diff i wanna buy is a true LSD, whats the number supposed to be on the 3bolt diff to make it LSD. looking to buy one just wana make sure.

I Don't recall the numbers but for one they should be easy to search on the forum. Also, if it is LSD, it will say Viscous LSD on the sticker.

Should say "Viscous LSD - B17" on the rear cover. Also, one of the axles will have a longer splined section than the other.

 

[MellowVR4]

SO viscous lsd-b17 that will be a true 3bolt lsd correct

 

[belize1334]

Unless the rear cover has been changed out. Make sure that the axles are uneven. Also look in through one of the axle holes. There should be 3 splined regions on an LSD vs. just two on an open diff. The two outer splines are for the main axle drive and then there's a third splined region toward the middle which engages the secondary splines on the Driver's side axle and operates the LSD.

could it be B15? does it have the hole for the 4ws pump?

I have a pair of 3 bolt mech lsd's and they have B15 on the rear cover, no 4ws pump and the fill plug says "use only lsd oil"

 

[MellowVR4]

how do you change the rear diff pinion bearings, diff bearings, seal. i tried searching but i could not find nothing, just trying to change them before i put it back on.

In the factory service manual, but it is not a 5-minute job.
