is permanent 4wd suitaable?
hi, i would like to know if permanent 4wd (l series) would be suitable for offroading.
cheers

Permanant or "Full Time" 4WD L Series gearboxes are okay for offroading. Locking the centre diff on one makes it drive like a regular L Series with standard 4WD.
However, the low range on the Full Time 4WD boxes is not as good for 4WDing as a stardard L. A Full Time box has a low of 1.196 and a Standard L Box has 1.592. You can swap the lows if you have the bucks or the know how.

Hey Learner,
Liberty and other AWD boxes after the L series AWD don't come with the centre diff lock, rather they rely on a centre limited slip diff when off roading - apparently the load rating of these change from the standard bottom line subaru (weak loading) upto the STI (strongest)...
If you've got an L series the hi/lo 4wd will be sufficient, but don't drive around on hard surfaces in 4wd all the time (this includes hard dirt roads that give no slip) - this will cause binding in the drivetrain leading to something breaking. When 4wding it is normal to feel some binding happening, but once you lift a wheel off the ground or reach a gravelly/slippery area it will take care of itself.
Hope this is of some use.
Cheers
