Hi there all
I have looked at aftermarket options for a rear diff lock on my 3.8 L LWB gen 3 pajero. They are all expensive and only imported on request etc.
The gen 4 came out with a rear diff lock if I am not mistaken. According to my research the ratios are the same on the gen 3 and 4. I see a few gen 4's at scrapyards.
Now my question is: will I be able to fit a gen 4 rear diff to my gen 3 and gain a diff lock in the process?

The early gen3 GLS Pajero's (2000-2003) had a limited slip diff (it is a torsen diff, I think audi R8 has one too) which is also lockable, and the Gen 3 glx also had them fitted as standard. Start there, would be an easier swap I think.
I think cloyd or jotto on the forum did that conversion on their gen3 Pajero that only had traction control. Must make an awesomely capable off road vehicle!
If I have funds available one day or find a cheap torsen diff at a scrapyard I will definitely also do the swap.

Thank you Nick. I have seen on earlier posts that gen 2 diffs can be used. My Paj is a 2006, in my logic I do not want to put even older parts on my vehicle. Therefore looking at the gen 4
For sure, that does makes sense. However the Pajero diff is incredibly strong especially the torsen version. I haven't seen a post/topic of issues with diffs in absolutely ages...zombie1 wrote:Thank you Nick. I have seen on earlier posts that gen 2 diffs can be used.

I would not hesitate to use a diff out of a scrapped older gen3 Pajero.

Zombie,
Cloyd did that swap on his Gen3 3.8V6 from an earlier Gen3.
A few things to be aware of:
1) When buying a diff off a different model, you will most probably have to buy both diffs. The only Gen4 with difflock is the diesel engined GLX.
2) The diff ratio between a petrol and diesel Pajero isn't even almost the same. A diesel diff in a petrol Pajero will rob you of all power.
3) Gen2 Pajeros have solid rear axles, so a straight swap will not be possible.

Thanx Roelf,
The early SWB petrol gen4's (2007 +) also had diff lock. A friend of mine owned 1.

Cool.... I know there are a small number of anomalous Pajeros out there. Always worth looking for those.
Zombie1,
I did diffs swap on my 3,8GLS. Diffs - because the ratio was different from mine - 4.3:1 (3.8 difff) vs 4.1:1.
I obtained both from Partshunt in Pretoria.
The mechanical swap can be done before lunch. You need basic tools plus preferably a trolley jack to lift the rear diff into place plus axle stands. Be aware that the flanges on the two rear diffs might be of a different size. If they are not the same, pull them out and swap them. Easy.
I have no idea how old or what mileage my "new" diffs had on but they are 100% and without any leaks or noise.
The electrical wiring takes a bit more time if you want to run the wires along the standard loom. My wires are of the correct colour code - in fact they were part of the purchase from the stripped vehicle. You must include the air pump for the diff and ensure that you also get the bolts and air pipes. Power for the diff is drawn from a blank power point in the cabin fuse box and the switch is in the blank next to the instrument dimmer rheostat. Include the diff lock switch as well as one of the on/off switches next to it. You will have to cut the top of the DL switch off and glue it to the top of the on/off switch - that is if you want a switch with the correct nomenclature (D/L)on it. You should also include a warning LED to inform/remind you that the diff lock is engaged.
The beauty of a swap as above is that you can have the rear diff locked in high range - something that is impossible in the standard fitment - it is only possible to lock the rear diff in low range. My rear diff remained locked for 5 days whilst touring the Namib.
This is a full days work but nothing special - knowledge or tools - is required.
