The QD32 powered D22 runs the (rear diff) same diff center as the GQ and GU front diff (H233B). The GQ and GU rear diff is the H233. Expect for a few models which run the H260.

The VG30E and VG33E run the same as above.

The ZD30DDT and the YD25DDTI CRD powered D22 runs the C200 rear diff.

Not sure what the KA24E/KA24DE models run.

I think the TD27/T powered D22's run the H233B aswell.

i dont know what the letters mean exactly but the numbers refer to the size of the diff
the H233 is a 9.5in diff
the c200 is a 8in one
the "H" and "C" i think are how the diff is mounted sailsbury or banjo
im pretty sure the "B" is H233B means its a slippy diff

also the front diff centers can be swaped out for a LSD type from a skyline, silvia or 300zx depending on what diff is in that vehicle.

i swaped out mine a couple of weeks ago from a silvia that had a R180 rear diff, let me tell you, you use a lot less right foot on trail duties

thanks for the info.

Interesting...what was the cost involed?
how big was the job? to change the diff center. does the front diff now respond like the rear LSD?

H stands for heavy duty.

C stands for commercial diffs.

The R180 diffs can be found in most CA18/DET, CA20S/E and SR20DE powered cars.

Any questions just ask.

im interested to hear bout this front diff centre swap aswell..

the diff center cost me $50 from a friend that does hipo work to imports
as far as the work involved i unbolted the cv's left them in there droped the cradle, pulled it apart swaped the ring gear and side bearings ( i have access to a dealership workshop) put it back in probably bout 4 hrs all up, i did it over a week after hours at work

cause the diff i got is a viscous coupling type it responds more when you spin it, tends to grab harder when loaded up unlike the rear that slips when give it too much,
be aware its not a locker it will "open" when enough pressure is put on it

i reckon now with slippy front and rear i am "nicer" on trails that previously req momentum to push me through

if i where to get a hold of another diff center i would make sure that it was the clutch pack one so i could shim it up more to have less slip so it was more "locked"

thanks for that. Would you know what the REAL cost is for parts, and were to get the parts from?
What model navara have you done this to?

as far as real costs are involved they change from place to place
you can get centers from any good import wreckers
and i did the swap to a 98 D22 ST 3.2lt

QD32 powered D22's run 4.6 gears, If I was you I would have put a R50 Pathfinder or V6 D22 (VG33E) front diff in (R200). Stronger then the R180 by far.

ZD30's run 4.3 gears, I am having trouble finding a vehicle that runs the R200 diff in 4.3 - 1 ratio.

I used to play around with allot of silvia's/180sx/skylines back in the day & I'm pretty sure the R33 Skyline Auto diff's are 4.3:1. Not sure if they are R200's but it would definetaly be worth a look. I might see if I can track one down & see whats involved with the swap.

I've never swapped diff centres before. Is it possible to be done in "the shed" with a reasonable amount of tools? or is it something I would have to take to the diff shop or similar workshop?

diff centre swap is pretty easy in these the only specialised tool needed is a dial guage for preload and backlash

but if your worried that its more a black art mechainics type of thing you can pull the center out zippy tie the shafts outta the way as they all unboult and take the diff "pig" and center to you local diff shop and let them do it.

while your at it you could take the whole truck in and have 4.88's installed into both diffs
