rear diff question...
I have a 95 f150 supercab 5.8 with a e4od trans 4x4... my questions are... If the rear is stock what is the ratio most likely to be? and also, is there a way to drain and refill the diff without removing the diff cover? thanks

If one or more of the cover bolts are removed-it will not drain and may break the seal.
Use one of those hand pumps and hoses to pump the old lub out through the fill bolt hole in the driver's side front of the differential housing.And then reverse the same pump and pump in the new fluid. I always use a different pump as to not cross contaminate the new with the old differential fluid.

ok.... so far as off road and 4x4 use how is the 3:55 gear?... what would be optimum?, and how hard would it be to change it out myself, i've heard that it can be a difficult task

And it would be difficult to change out the ratio yourself the first time-I have heard. The gears have to be shimmed just right and takes experience to do it right the first time

yeah the first time you do gears always have a buddy around who knows what he is doing, the higher (numerically) the better for offroad use but if you want to drive on the road it depends on what size tires you have with 33s and a a v8 4.56s are good the bigger the tire the bigger the gear

I have 31 inch tires on it now, about as big as I can go in the front without rubbing. I was just asking for future reference, someday I would like to upgrade the rig for serious off road use

There is always something bigger and badder and your ride can always be bigger and badder. Unless you are unhappy with your rig, leave well enough alone! If you have a lot of money and time then it's different. Just my $0.02

On a 4x4 i like 12.50 - 33s Good off road & on street..The bigger the tire the more gear you need plus you have to have the HP to turn them & need a bigger lift . The bigger the truck & tire the more weight . I allways liked the lighter 4x4s . Thought they were more fun . With 33s & your trans 456 would work good . JMO . Lew

thanks for all the input... I was thinking of leaving the tires the size they are now, I think they are big enough... but maybe going a couple inches taller eventually with a lift. I think the tires would still look ok because they are oversized now for being stock ride height. I get comments all the time on how big the tires look...lol
