Coilovers would make it A LOT easy to package everything. I just already have coils and these shocks are new. I'll see how it goes. Might end up with coilovers yet.
Do it mate

What transfer case are you running? I was planing on flipping the diff and using a rear diff center so the crown wheel isn't back ward so i can keep my set up. I've alread spent a lot doing the 8.8 and by the time I've spent money on the gq diff i could have a built d30.

I've got a Dana 300 with NWF billet gear reduction in front of it for a dual transfer case setup. See post #6. It bolts directly betweem all TJ gearboxes (and AW4's) and the D300 without any adapters... pretty trick aye.

If you flip the rear diff centre, it'll run backwards. The crownwheel relief in the housing will be on the wrong side when flipping a housing which means the pinion would turn any crownwheel the wrong way. It's easy to clearance the housing to put the crownwheel relief on the other side but you'll need to weld the stud holes, machine the face flat and re-drill and tap the stud holes. I've seen some Hilux guys do it but more of the studs line up on them.

I spent some money on my HP30 and 44 setup too but I sold them for a decent price and it covered the purchase of the Patrol diffs, chromoly axles, front locker and new bearings.

It'd be weird running the 5x4.5 rear wheel pattern and the 6x5.5 front wheel pattern. Plus, you'll have the GQ rear diff in for less than what the 8.8 will fetch... Rear Patrol diff = $150, front centre (if going for a rear high pinion) = $80, shim for rear LSD = $8, shaved centre = $5 in scrap plate, brackets and coil seats = $150. Total = $393 total for a strong rear with high pinion, awesome LSD and 33spl axles. They don't have the handbrake on the rear though so I'm planning to put my Subaru Leone calipers on the rear discs so I'll have a real handbrake = another $180 for calipers and pads. Cables look like they'll fit right up.

A built 30 will never be close to the same in terms of strength, let alone the manual locking hubs, bigger brakes and no inverted Y steering... This was my reasoning anyway. A 30 will be easier to build and is less likely to attract the attention none of us want. The D300 was my main reason for going the Patrol diffs and, due to the much lower gearing, and therefore increased torque, the extra strength will be needed.

Got a bit of work done on it today.

Installed the front locker and set up the gears. It's so much quicker on a removable 3rd with carrier adjuster nuts compared to a Dana that also requires shims for carrier placement and bearing preload.. 12 in/lbs preload on the pinion bearings, pattern that's long and nicely in the middle of the gear face, 15 in/lbs carrier bearing preload and 0.2mm (8 thou) backlash. Strong, quiet and reliable setup.

Opened up the Dana 300. Bearings and gears look great so I'll throw some new seals in and be done with it. I removed the shift rails to remove the interlock pils for independent control of the front and rear output shafts. You have to remove the idler gear to get to the set screws that keep the shift forks on the shift rails. Not that bad of a job really. Also removed the shifter bracket from the front output bearing retainer for more clearance.

Got the 3rd member in the housing and threw the Longfields in.

Pics showing:
-chromo CV's
-D300 with cover and idler gear removed
-cable twin stick shifter and billet D300 cover - cover should stop leaks and add to the case rigidity and therefore the gears strength
-Dana 30 axle next the Patrol chromo. The cross-sectional area is 32% more in the Patrol. Throw 4340 chromoly into the mix and the axle is theoretically over twice as strong.
