recently regeared installed detroit locker up front

the car has been pullin left quite a bit so i took it for an alignment today

the alignment guy suspects a problem with tcase or diff causing a "drag" on the front drivers side wheel since there isnt evidence of a dragging caliper or bad wheel bearing.

with the wheels in the air, in 2wd, if you spin the front driver wheel by hand it is noticeably heavier to turn than the passenger. you can also see that the front drive shaft spins along with the front driver side wheel. the front passenger wheel spins by itself with much less effort.

im not stuck in 4x4 bcuz the front wheels spin with the rears on the ground

what else can cause this kind of behavior?

I'm assuming the ADD system is still intact and functioning? That disconnects the passenger side CV shaft from it's spider gear in the trans. Normally, this lets the driver side "almost" freewheel as well, but the CV shaft will still be spinning the spider gear. And normally, that's where it stops. The spider gears spin, and the diff carrier/ring and pinion/front driveshaft don't turn.

But with an LSD/non-switchable locker diff in the front, the driver side wheel will still be spinning the diff, and thus the driveshaft as well. But the passenger wheel will still be disconnected.

You might need to either:
- disable the ADD system so both front wheels are 'engaged' and have equal drivetrain drag
- use a selectable front locker that can operate as a completely open diff when not in use
- or add manual hubs
