Limited Slip Question?
Ok guys I know this might seem like a stupid question, but I have a 2002 F-150 4X2 with a 4.6 (not that it matters) and and I want/need a Limited Slip Differential. I currently have just a regular dif with 3.09 gears (I think) and I was wondering if there was anyway to install a LSD without doing axle swap? What would be the cheapest? Thanks for any input.

You can install a LS diff. using your own axle. That's what most guys do "including myself". Around here "Arizona" it would run about $800.00 for the LS diff and install. You might be able to find an axle for a better price but It would hard to find one with the factory LS that match your gears. Most trucks came with 3.55. If you have the 3.08 gears it might be better to get an axle with the 3.55 and LS. That would make your truck pull alot better.

Yeah I was thinking it would be better with 3.55 gears but how much would that effect my gas mileage? Normally I wouldn't ask but gas is like $1.30 a liter here in Ontario. Also how hard would be to do that axle swap myself?

Nope they are still using the 8.8 just the F/E-150s with the 5.4 use the larger/stronger 9.75 rear end.
