xxxcr diff barking

[harryg]

hi folks, please help very disappointed, my xxxcr diff began barking when racing in mansfield last night, got home stripped and cleaned everything, clear grease applied and put back together, ran on my drive for 3-4 minutes when it started barking again? tightened up again ok but why does it come loose? it sounds like a bag of broken marbles-very metallic! if the diff is knackered what parts are actually knackered as i cannot fathom what breaks down? please help as my faith in the xxxcr is diminishing rapidly, I must persevere for all my mates use b4's are cannot bare the hideous remarks of my xxx or my inability to run consistently Thanks in advance. h
