IMO some of these plug welds may not be upto spec when they left B/W.
It may pay to have a pro drill out and re weld them if you are running sticky tyres, trick suspension etc.
Thats what i was thinking....
I was looking at a 08 model Nissan Navara at work the day before i posted that, has the same design diff. I looked at the plug welds and only one on the whole diff was satisfactory. Two the weld wasnt even actually on the axle tube.
I see what you guys mean about more weld not helping though, think i may just drill out and re weld when i get one.
Cheers.
