Discovery differential flange torque spec

[AdamSanta85]

I am in the process of getting a set of 1995 Discovery axles cleaned up to swap into my truck. 10 spline to 24 spline. The donor truck had that 3 bolt diff flange with the rubber donut cush drive thing, I am swapping to the 4 bolt. I have the STC4858 conversion kit, but I need to know the torque spec of the differential flange. Anyone have it handy?

This video (like many of his) has been super helpful so far, however he says check the manual for the spec. I don't have a 95 Discovery FSM.

I have a Haynes manual, I'll check today to see if it's in there.

Looks like a range from 70-120 lbf. ft.
With most torque settings on a Landy "tight"

Hm ok. I am usually a firm believer in tight as well, however the guy in the video stresses that the differential bearing preload backlash is set by the torque of the flange bolt so it is important to get it dead on to spec. He gets into that at the 6:00 mark. The diff he is doing it on (300tdi 95/96 which very well could be the same as what I am using as the year is the same) is 130NM.

However in your snippet it is def a "tight" scenario... hmmm

Adam, I watched the video and now understand your questions. It looks like they gave the nM spec for 300tdi. there should not be a difference between engine and rear diff as that part is the same. i would go with their spec of 130nM unless anyone else can chime in why that is different for a V8, tdi etc.

130 nM equals 95 ft pounds so in the middle of the above range. Probably the correct number.

Thanks. I would assume 1995 diff is a 1995 diff. I am not in a rush to do the job so I will wait and see but I agree you are likely right.

Years ago I helped a friend remove the Rotoflex/donut...dagone that sucker was hard to break free.
Use the bolt and washer method like the video but be prepared with extra curse words!
Might even need to invent some new ones!
