Hey thanks for the link but it’s not right, that’s all I could pull up too but that’s for a Dana 30 and mines for a Dana 35 and that one is shaped different. I’ll send a pic of what it looks like partially assembled.
I would say possibly I could contact another company and get their springs but no company seems to sell a lunchbox locker with those springs around that main pin. This seems to be a different lunchbox locker design than others on the market.
X2, I forgot to ask the OP @ShaneMK if his Dana 35 is stock or not. If it's still running OE size 27 spline shafts they are ticking time bombs with that locker installed into it.
Counting the splines inside the locker in his pic, it appears that he does have a 27 spline axle.
Yeah I couldn’t get anything to pull up either with the numbers I searched. As of right now I’m putting 4.88 gears (bought the jeep with a slight diff issue, but it made 2 years with me driving it hard on and off road). The previous owner was the original and I’m not exactly sure everything he had done to it over the years but at one point he put that locker in. I never personally had an issue with the locker but could have been what caused the drivers side carrier bearing to completely shred itself? I believe the axles are the stock ones, but I don’t see any markings on them to be 100% but they are indeed 27 spline.
Having a rear locker can exactly double the torque/stress seen by a single axle shaft. The factory Dana 35 axle shafts are known to snap if you either install a locker into the axle or install 35" tires.
When the rear is locked, both axles turn at the same speed. The reason that this is Bad is because during a turn, they travel different distances: The outer wheel has to go further than the inner. With a locked diff, this puts a LOT of strain on the components, and eventually something WILL break.
Automatic lockers the OP's lunchbox (plus Detroit Lockers etc.) automatically unlock the outer wheel during a turn so it is free to rotate faster than the inner wheel. The issue that caused her breakage was when one of her rear tires was in the air and the other one on the rock was then receiving 100% of the torque instead of it being divided between the sides. That 100% of available torque the busted shaft received was what broke it.
Thank you so much! That helps a ton I’ll contact them and see if I could get those springs from them.
That double-diamond trademark was bugging me, I knew it but couldn't place it. Thanks!!!
Yeah yeah I knew about that but the lunchbox locker is supposed to disengage when turning but I’m sure sometimes it doesn't. Well I’ve experienced many times when it doesn't (usually only when I’m sending it really hard and I try to take a quick turn, yes on pavement) but I inspected the axle shafts and there dosent appear to be any twisting of the splines at all.
