July 22, 2004Any one knows whats the difference between a 3.73 Rear Axle and a 4.10 on a Yukon 2004 with a 5.3 L engine ?
is there different suspension configeration between the two ratios ?
i.e. is the 4.10 rear look lifted more than the 3.73 ?
finally why would I need a 4.10 and not the standard 3.73 ?
