Hello! Does anybody know if a ring gear from 4.11 h233b diff will fit in the 4.6 lockable diff from 2,8 gq? The plan is to take the whole 4.1 diff centre from my 4.2, remove the open diff from it, then take a lockable diff unit from 4.6 diff and put it in the 4.1 diff. Then finalli install the new born 4.11 lockable diff centre in the axle fro 2.8 and use the axle in my td42 gq. Hope it made some sense.

The 233 is the diameter... any diffhousing internals running stock gear should be interchangable within that size.
The spiders/lsd clutchpack on all TD42 rears iirc(!) are all 33 spline so changing over the driven assembly should be no drama.

Hi mate. I have read your post a few times and a litttle confused? so what you are really asking is if teh difflock out of your 4.6 will bolt into your 4.11 centre? You dont intend to change ratios in your diff? retaining the 4.11s? as mentioned above it should all swap out. Yu may not enven need to strip the crownwhel out so no backlash setup.

Where are you located mate? the 4.6s are desireable and you may get some coin for them to be honest as they are a great upgrade for running bigger tyres. I run 4.6s out of a 2.8 GQ in my GQ with GU Diffs and 37s.

He wants to use the full 2.8 GQ housing/3rd member and axles with the ring&pinion from his 4.2 GQ.
The 4.6 hi-market value is a nice tip.

Yes, I drive a gq td42 with Open 4.1diffs and am planning to use 4.6 axle with diff lock from my 2.8 gq doonor car. Goal is to combine a lockable 4.1 diff for my gq td42.

Ok. Then just swap out thr locker. Remove the 3 rd member and just strip out the locker. The Axles and housing are the same. H233 are all the same across the GQ and GU range.

Since we are talking about diffs, let me hijack this for a bit...

What about the front diff? Are front and rear 3rd members interchangeable, same bolt pattern, same splines on the spider gears? Something that crossed my mind is if someone who finds a OEM selectable locker rear, upon installing it, would be able to move the previous 3rd member with the LSD up front... Not really sure even if the rotation is the same, some fronts are reverse cut, just wasn't curious enough to note it when under the Patrol.

In my Samurai for example, both 3rd members are the same. The only OEM difference is the front axles have a smaller spline count, solved with aftermarket axles.

Front and rear: No.
However, the rear internals from a navara (31 spline iirc? or 28?) will fit in the front of a safari...

I did have plans to put a narva LSD up front of mine but was told that it can cause "crabbing" (driveline bind causing the whole vehicle to want to go sideways rather than foreward) so scrapped that idea.
I did upgrade to chromoly half-shafts and CVs up front, but they're stock on the spline count at the diff end.

If you really needed more grab at the pointy end then It's generally recomended to fit a locker. Vacuum (nissan oem) or electric (eaton etc) but you pretty much lose steering to gain acres of pull.
