i have done a decent amount of research on the G 80's... i want to buy one form my 2007 colorado 2WD... i'm curious if anyone has any personal experience with these and if i should buy? depending on who you talk to some people love there G 80's other don't and suggest the tru trac LSD... some say with the 1/2 ton chevy's that G 80's are "time bombs" and they will blow up by playing around in your truck for example burn outs doughnuts and such.. implying they are not built strong enough and when they "lock" there can be "jerking, loud bangs, loud clicks. from the research i have done it has been implied that the newer G 80's are different then the old ones so are the previously stated possible problems from the old G 80's.. other then the possible negative aspects of the G 80's i am impressed with you tube videos and such i can get on off line for about 500-600 dollars and can anyone tell me how difficult it is to swap out a differential sense the G 80 is an option for the 2 wd colorado's do i need anything other then just the G 80's or will it be a simple swap out any input or suggestions would be greatly appreciated
