I’m looking for some input from land cruiser community for my project. My goal is to create a full floating rear axle for my 1999 runner with selectable locking hubs so that I can flat-tow it behind my RV without burning up my driveline components. I am also looking to benefit from the 9 inch differential that will have to handle the torque of my TDI diesel, which should put out around 310 ft lbs at the crank. I also plan to run a reduction box between my transmission and my transfer case, so the torqhe applied to the Drive line down stream from there will be substantial greater than stock. I am also looking to benefit from the addition of disc brakes and the ability to retain the 4runner‘s ABS.
My understanding is that the Land Cruiser’s rear axle is 63 inches wide compared to the runner which has an axle that is 60 inches wide. I would cut 3 inches off the long side of the Land Cruiser axle, which will center the differential. Then I will need new axle shafts for both sides with the correct lengths and splines to accommodate selectable locking hubs, which I believe will bolt right up to the Lancruiser wheel hubs.
I am also thinking that a 9”Electric locking differential would be nice. My runner currently has the smaller version of the Land Cruiser locker. I’m wondering if the wiring will be plug and play?
