I just bought another jeep the other day. 2001 I6 manual. the previous owner had installed an Aussie locker fairly recently. everything works fine in the jeep (other than my lack of skill while driving a manual) except when I take a turn i hear a banging coming from the jeep (i think the front but not forsure more than that) and at times it seems the jeep jumps/jerks during the turn (similar to when i mess up shifting into first). i have looked some stuff up and have seen similar issues but they are all still different. i am still driving back from minnesota but will have some time to check it out later today and am looking for ideas as to what to check

i should mention that it works fine when driving straight. only has the problem while turning

That is your front locker engaging while you're turning. You can adjust your driving style to prevent this by using neutral throttle (neither accelerating or decelerating) through turns.

Thanks! That took care of the sudden jumps while turning however there is still a loud clicking noise whenever I turn. Is that just something that will go away with time as i break the new parts in or do i need to look at the differential and stuff?

So these lunchbox lockers engage when the front drive shaft is not engaged? As in 4wd is not engaged and driving the axle.

They are activated by small springs that don't take much to activate and deactivate. So the forces when turning slowly in high traction, say a parking lot or gas station, force the locker to lock/unlock very lightly. This causes the bucking sensation since the front axle shafts are free from the hub/tire like a manual hub equipped rig. You get use to it and drive as mentioned above.

Would be a good idea to check the torque on your control arm bolts and make sure you're not getting any extra motion due to the entire axle rocking back and forth. Had a similar issue with a lower cam bolt being loose causing the axle to give similar jumping sensation per revolution while turning at slow speeds.

Thank you. Did not realize they would lock on a non drive axle. I thought in order for them to lock they had to be under drive pressure.
