Ok finally my question- I have a Series 3 ute with a sals rear. I would like to put some type of locker in the rear, and i think budget will only stretch to an auto type (detroit, Lock Rite etc). I have heard mixed reports on the succesfulness of doing this, due mostly to the single pin carrier, and axles. Can someone give me a bit of advice on what I need to do to the rear diff to save embarassment in front of my J**P driving mates?
I currently run a 750x16 tyre, but down the track would like something a bit larger dia if that affects anything.

Thanks again

The sals is a 4 pinion diff very strong , You will be going to break one of these
Now the front diff iss a different story

ok it seems I have been confusing myself!! Thats good to know. I found it hard to believe something that weighed about half as much as the 4wd would bring me unstuck!!!
The front diff might have to wait a little, I'll drive with fingers crossed until I can do something with it.
Any advice on avoiding breakages here?

We've never broken a diff in any of our rovers (standard diffs) and we give them curry every so often

CHEERS TIM.

excellent. have to say i've been amazed at where I have got the old landy so far, and without drama. I guess if 2 of them can keep a rangie under control (most of the time), then it should hold up to 1/2 a holden's power!!

The Salisbury you will not break, locked you may break its axles
In close to 30 years of Rovering I have never broken a front diff and I have given them a bit.
When you break it then look at replacing bits, the cheapest locker of a Salisbury is a Detroit or no spin centre
I have run one for 2 years without issue and am more than happy but you may be wise to run Maxi axles

ok sounds good to me. The maxi axles are a little hard to find, and quite expensive if they do come up for sale i have found. Has anyone heard of any processes to strengthen the original axles? Getting them heat, cryogenically treated or otherwise??

Nope maxi axles or mcnamarra axles are your best option
In saying that a few on here hate dealing with jeff mcnamarra

righto, I'll be doing some ringing around and keeping an eye out after christmas then. Thanks again !!
