Don't know if I am getting axle wind up on bitumen in my HJ75 . Found a broken stud on rear axle and one loose also a slight weep. I drive the vehicle very easily through corners and roundabouts.
Anybody had this problem.

Yes a mate of mine did. Went back to a slippery in the rear and the Detroit in the front. Problem solvered.

I have noticed other people complaining of the same broken stud issue with 75 series, lockers or not. Perhaps that is why Tojo has gone to the five stud type with larger studs? You will just have to keep a keen eye on them. Personaly, I did not have this problem when I had my 75.

You should not be getting windup at all unless you are in 4wd on the black top. I think it is another Tojo problem as a lot of others have complained of the same thing. However Tojo will not admit it.
I used to have a handle on life, but it broke.

You are way off the mark Dodger. A detroit locker will get diff wind up on a hard surface when doing a tight turn. It is the design of the diff that causes this. It is just the nature of the detroit locker diff.

LSD's get a little as well on really tight corners. In a car with a properly working LSD you can feel it when on full lock on the black top. Just try it if you have one.

This is not transmission wind up it is diff wind up.

This is quite common...the diff action on hard surfaces is harsh enough to work the weakest point, or these studs....the best way to fix it is to install 100 series rear studs that are 10mm compared to the std 8mm ones...a bit of machining of hub and axle is reqd, however, once this is done, all is alot stronger.
My old 80 had one in the back and the axle fell out once......
Common problem....air locker is the best fix...

I bet it is the drivers side...(shorter axle, less give)

Fairly common It can be caused by bent axle or sometimes just happens. The "loose one" is probably not loose at all but broken as well and chances are the rest are cracked and about to go. If too many are busted it is cheaper to get a second hand hub than drill the others out. That slight leak and distortion of the gasket are the first sighns of impending doom. I have driven one home with only one stud. Just get it fixed and dont worry about it (get the axle checked for straightness) it is not a fault but more of a tendancy and chances are you will get another 200 thou out of the next lot

I had a Detriot locker fitted front & rear on my magic little Rocsta diesel SWB.As it has FWH on front axle (free wheel hubs),front locker,no effect on black-top..Rear locker was deadly when lifting foot from throttle before a bend,threw rig to right,right towards oncoming vehicles..Then we measured rear tyres..One was a little larger (measure around circum..not diameter)..Matched up tyres and was a lot better..Kept the one Detriot in front and went back to LSD in rear..Previous post has the clue..ARB air locker in rear,Detriot in front (if you have a FWH..like all 4x4 should).....I always un-do wheel nuts then "hand" re-tighten after tyre fitters have used their "Rattle Guns" as they often over-tighten,dramaticaly...Note! Dry metel to metal can "weld" the nut thread to stud thread.A dab of grease or motor-cycle waterproof chain lube will keep out water and prevent thread lock..(I have ARBs f/r on my Wrangler,don't even know they are there 'till I need them..Way to go.Real compressor is a bonus)

Thanks to all for replies,
It is my axle studs that are the problem and by the replies it's a common problem.

My locker also throws you slightly sideways but I have learnt to control it by easing up on the go pedal.

I will be changing all the studs and keeping an eye on them. If it keeps happening I will change to a air locker, that's if I can hide it from the missus.

Thanks Grumpy
