Changed out my diffs/gearbox/transfer case oils yesterday.... Looks underneath car this arvo to see a puddle of oil under the front diff. After scrubbing it off with a wire brush I found a fine crack alongside one of the welds on the front edge where the oil is weeping from. Can only assume the original level was low enough not to show and now I have filled her up she leaks :(
Now ... How to get it repaired?
Ideas ?
Suggestions ?
I know a bloke who had this happen to his early mdl GQ. They drained what was left of teh oil. Sprayd the area with Aerostart (or anyother good degreaser will do the job). Get someone to weld it back up. Paint it if you like then fill with oil.
As long as it is just a fatigue crack it is an easy fix. Early GQ's with out swaybars tend to have this problem. I am waiting for mine to do it.
How long do u think the crack is?
If its not too long then prob just a fatigue crack, if its larger then it may be more series and could cause more problems.
Id say just a weld will fix it up fine for ya

Crack is probably 2 -3" long at best and right alonside an existing weld. I havent done any heavy 4Wd work or smacked the diff on anything so I guess its just fatigue.
Any ideas what would be a reasonable cost to have it welded ? My welding = birdshit
you have a GQ?
been through this fourteen times and tried all sorts of welding, drilling holes at the end of cracks etc.
had it done professionally a couple of times, tried welding inside and out, brazing, arc welding, mig welding etc.
corrugations are the worst offender for starting it.
pretty sure the only way to stop it is to brace the housing as i think the pumpkin is moving up and down in relation to the hubs.
later model housings don't do it

Not sure how old your truck is, but this is a common problem on early GQ's. My rear housing('89 GQ) has cracked right beside the pumpkin, right where the welds join at the tip of the triangle. If your in Melb, go and see Cheezy and get him to weld it up.
Took a drive into Alice on monday and put on a concerned face Welder took one look and laughed .... Apparently does literally dozens of repairs on Cruisers and Patrols alike. One particular 2000 model Patrol that gets the shit flogged out of it on the corrugations has been welded 14 times so far ... Cracks in a different place each time.
An hour and 65 bucks later she is all fixed (along with the smaller crack I hadnt seen ! )

Cheers Have a Fitter / Machinist mate at home who would be happy to make me up some braces if I ply him with a little rumbo !!
