As tombie says - if only one then rear. The rear has most traction when climbing, and you can engage the rear to keep the car straight when going down steep hills.

I prefer manual lockers, and have MaxiDrive and ARB. Both work well IME. McNamara lockers are also a good option.

KAM make an e-locker, which some people on here use.

As above, rear first. Both wheels locked at the rear is what you need for hill climbing or getting out of a hole because of weight bias.

Also, sudden loss of traction is far less destructive than sudden gain of traction once wheel speed well above ground/road speed. That's what generally breaks things. In that sense lockers are more kind, but they do cause significantly higher loadings when in turning on high grip surfaces, especially when in the front end.

This may be a stupid question, however;

Is there any benefit of a rear locker without a CDL?

I am thinking there is no benefit and I should wait until I rebuild the transfer case with CDL (2002 D2).

true, no point in rear locker without cdl

No, don't bother with a locker until you have an active CDL. CDL is your first port of call, then rear and then front last.

Second that!
Since activating mine, it has transformed the ability of the car incredibly.
Instant difference. Never thought it would change the vehicle's ability to such an extent.

Though I reckon the 235/85r16 Hankooks helped it out a bit too!!

What the others have said. As a case in point, Travis (Aquarangie?) used to have a RRC with viscous t-case and a rear locker. A worn viscous T-case takes a long time to lock up. I will never forget Trav attempting a hill with the rear locker engaged. The first couple of times (before the centre had "locked") he would stop with only one front wheel spinning and nothing else. The same would happen to you with a rear locker and no CDL.
