I bought the LST bout 2 weeks ago, been hammerin down on it since, trying to break the damn thing so I know how durable it is, and so far, no breaks! HOWEVER, I was hearing a crackling sound on hard accelerations, mainly on pavement, I thought although unlikely, it may be the rear diff. I took the rear diff out, and inspected the gears, everything checked out...what noises did your truck make when the hexs were slipping? has anyone else experienced this?
