Finally got the truck in the garage to replace the failed 4 link mounts only to discover the left hand axle tube has fractured nearly 360 degrees,the crack had followed a ground down weld left over from the removal of a previously offending,poorly engineered 4 link set-up.!
That might explain why I was getting an oil leak (I thought the vent was at fault initially)and a strange intermittent vibration from the rear end which i'd chalked up to the pinion angle being slightly off due to the aforementioned mounts which had cracked along the full length of a TIG weld. (Both sides,a year apart did this)
I'm horrified to think what could have happened had the whole thing let go......

I just with this truck would stop biting my 'A'.
