Is the GQ and GU transfercase the same

[AB]

same same...

TRANSFER CASE; Not much goes wrong with Patrol transfer cases, they can take a huge amount of punishment (and horsepower) and rarely fail. The transfer case is the same across GQ/GU models regardless of engine or gearbox. Low range ratio is 2.02:1. Not a particularly low reduction with low first being the only gear lower than first high, but aftermarket reduction gears are readily available in a variety of ratio's.
Except for GU 4.8l, GQ/GU Patrols are fitted with a transfer case mounted drum handbrake with very strong holding ability. The handbrake (on the rear of the TF case) can be adjusted easily by removing a rubber bung from the drum, moving the drum so the hole is in the 6 o'clock position, and using a screw driver through the hole to move the adjuster.

Only one way to find out mate
is ring or go to 4x4 wreckers
ask or see if they would fit

They are the same so I have been told today I think I've found the problem might be the locking/glide plate it's only an issue for 4hi at the moment

I have a spare trans case but not sure yet if a want to keep it as a spare??

As for 4h... ya dont need it as long as you can get 4L fixed...... hows the diff going???

[healy]

But are they the same???

Yes, The same gearbox as well as later gqs (which is the same as earlier gqs, except with a couple upgrades). I think there are two gearboxes behind the td42 with minor differences (maybe the pto attachment is the difference, but the part number is different). Transfer cases are the same though. You can confirm that with a look at the part numbers for both vehicles
