Help 1997 f150???
what gears and what kind of money are we talking about? if its not LS and not positive track how will it pull in mud good or bad?? thanks for info!! let me gues one or two tires pull not all at same time?
Front and rear gears plus installation by a shop approx $1500. Add about another $300-$500 for a locker for the rear.

I'd go for 4.56 gears, since he's planning on thrashing the truck...
like suggested, install a locker in the rear at the same you do the gear swap
as for as what i do with gears.. the locker !!just in the rear or front and rear??? im learing guys i no some of what im asking may sound stupid to yall.. but i thank you for your help and ideas!!!!! i have'nt much money to work with right now so ill see what i can do now and more later!!!! what test can i do to see if somebody hasnt allready put one in without pulling cover?? thanks!!

To determine ratio:
http://4lo.com/calc/gearratio.htm
You will need a tach and a GPS. Drive it so it's in overdrive with the torque converter locked up, it's probably best to do this on a level road at around 65 mph. Note the RPM's and the speed from the GPS. Use the calculator and enter:
Tire diameter (you say you have 33's?)
RPM
Transmission ratio: 0.7
Transfer case ratio: 1
MPH
Hit Calculate and it will show you approximate ratio.
To determine if you have limited slip, put it in Park, leave the E-brake off, and jack both rear wheels up. Try to turn one. If it turns easily and the other wheel turns the opposite way, it's an open diff. To make sure, put it in neutral and turn one wheel. If it's limited slip, the other wheel will turn the same direction and the driveshaft will also turn.
If you have 33's and a 3.55 with a 4.6, you are behind the power curve at low speeds. No amount of tuning is going to improve your gas mileage or low end grunt much.

only add a locker to the rear otherwise steering will be an issue while locked in 4X4
I didn't say anything about you trashing the truck, and I'm sick of your attitude good luck on your decisions in life

I think it's your poor grammar and spelling that's confusing people. You may want to take a bit more time to try to write posts that are easier to read and follow. I'm not trying to be the grammar and spelling police, but when you are sloppy like that, it does affect the way others see you.

, its one of the downside of internet communication, loss of tone when typing. Whenever I think someone online is showing an attitude I just re-read what they said to make sure they couldn't possibly have meant anything else. I don't see where you said anything wrong either.To quote Cool Hand Luke.... "What we have here.... IS A FAILURE..... TO COMMUNICATE".
