Hey guys i got a problem with my dana 44 rear axle. Stock axle 3.54 gears stock limited slip (i believe). My problem is at extremely random times i will hear a bang from the rear and jeep will jerk forward as if someone just bumped into my bumper. The random part is when it does it, its done it on highway on regular streets on neighborhood streets and offroad. So its not at any specific speed and it doesnt always do it. Sometimes it will do it once sometimes 2-3-4 times in a given trip and sometimes it wont do it at all. Always when straight, never during or right after a turn. Thx in advance guys and for your time.

well i had time today after work to work on jeep just got done actually. nothing was loose i did drain and refill the diff with royal purple. the oil smelled like straight 90w which is not what book calls for so ima guess they never put the LS additive in it either so im hopin thats all it was. also greased up all u joints. So tomorrow i guess ill find out if it still does it.

Take ur diff apart and see what locker or LSD u have. Then replace the springs or any worn parts
