What's the average price of a 3.5 differential, and average cost for labor without getting bent over without lube?

No idea on cost...I paid $350 I think which I was told was a good price. Labor...free cause I'm installing it myself

Thanks and good call Grant. I'll have to see if I can source a set this week.Originally Posted by Gdup35sedan
Very nice Chris! You should pick up the Whiteline diff bushings and throw them in while everything's already out!^^^It def does not increase your gas mileage. It is shorter gearing so you'll reach your desired RPMS faster in every gear.

Dang! That's nice. I hate driving at 80 mph and doing over 3k. Wouldn't that in turn save on gas though?

My gas mileage went down on freeway trips by almost 2 mpg but around town it didn't change a bit. I'm running almost 300 RPMs higher at 80 than the 3.3 did.Originally Posted by g35snoop

All in all it was a very worthwhile mod. If someone has a shop install it it shouldn't cost much more than $100 in labor as it's about an hour and a half job.
