#1: While replacing my front pinion seal I checked the tags on both diffs. my front dana 30 says 4:10 and my rear dana 35 says 4:11 is this correct? #2: The yolk on the front diff. is marked spicer. is this factory installed brand? Thanks for your replys!!!
My jeep has 3.08 in the rear and 3.07 in the front. It kinda helps a little off road because the slight difference In the gears will allow eather the one axle to push more or pull more depending on what is in the front or what gears are in the rear. Better traction.
