Outer Limits 4x4 Board

Hi all,

I have a 02 gu wagon fitted with a 6.5 chev,315 MTZ,crown + pinions out of qa 4.5 ltre petrol (3.5 ratio ?)

I have noticed a noise whilst under continuous load only, as in while running for long period of time in soft beach sand
i can only explain as if something is wound up and then lets go with a loud bang , the auto part of the hubs have been removed so now are manual op only.

any ideas please

An obvious question, but are you sure both ratios are the same?

as far as I know they are,the centres both front and rear were done when the engine went in

are both diffs "Open"
How long have you had the car?

Could one have an auto locker in it??

Had the car since new(2002).
Got me buggered as to what it is,definitely comes from the passenger side of the car though.wheel bearings were replaced less than 5thou ago so all is good there.

Sorry missed a question,slippy in the back,no locker in the front.
