Broken axles and locking diffs

Do yourself a favour...the locking diff will make a huge difference to traction...but make sure you ge one that replaces the whole centre with something more substancial...because the 80 had a nasty problem with shearing gears in the diff, from a weak centres ability to hold the gears rigidly. The cheapest lockrites use the std centre, and you will be replacing gears b4 c/v's....aswome traction gained from this mod...worth it.
Now, on the bad side.....when 4wding in high range, you wont be able to steer unless you back off with an auto unlocker. then when you power on, the steering wheel will rip out of your hands...i hit a tree doing this on a winding track....auto lockers are good for traction, but bad for steering, tyre wear and axle studs...however in the front they do the least amount of havoc...as they are off when on tar...but you do loose the go fast on dirt roads in 4wd ability, and accelerator steering becomes the norm....My advice...ARB locker and loan.

Ok, my experience was in a 60 series, i was on a tight track in between trees and was on and off power, in low range, once the wheel ripped out of my hand and i hit a descent sized tree taking an intch thick piece of bark out of it....
