Installed my 4.56s gears Sunday with the help of Scott (big04ranger) thanks a bunch!

Anyway, drove down to indianapolis and got 16.2 mpg on 4.10s and 35s.

On the way home, I got 15.9 mpg on 4.56s and 35s, same speed set on the cruise and driving habits were the same. But gas mileage really wasnt the concern. lol

We replaced some of the bearings where we saw fit, but for the most part everything was in great shape. Install wasnt as bad as i thought at all.

After we got my 4.56s installed we finished installing 4.88s on Scott's truck. both were completed and driveable in about 8 hours.


I love the torque now, its awesome. It was definatly worth the work.

I have a few pics, but not anything to look at.

 

Sounds sweet man, maybe I can get a ride in the beast soon hint hint.

 

lol any time. any time.

 

Cool, good to see that you didn't hurt your mileage much. Were they easy to install?

 

mine actually went well, but we did run into some issues installing the 4.88s into scott's truck.

the problems i had were comon on a gear change.

 

Glad to hear bro but i think i already knew lol...

 

lol, yaya

 

how long did they take?

 

read. :)

 

What problems did you run into with the 4:88's? I may install those on the bronco when I go bigger with the tires.

 

constantly shimming and pulling them back out.

but the problems there cant really relate to the problems you may have in the bronco, two completly different axles.

 

Actually, I thought the broncos had 8.8 rears... I know my '90 did.

-

 

oh well i guess when i said that i was implying the front. sorry.

 

Yep and yep, I have an 8.8 rear, and the ttb in the front. I'm just trying to get a slight idea of what I'll be in for. Also planning on adding a locker or lockers into them as well, figure I'll do it all at once.

 

just remember the more you change the harder it will be to get the gears set right.

 

Awesome zach! I gotta do 4.30's or something now....I still wanna swap my 8.8 but now I have to PAY to get it done...how much would that be?

Cheaper to just get gears?

 

you have the 7.5 now right? and why would you have to pay to have someone swap your axle?

 

sweet man. sounds good.

any more sand come out with the fluid?
lol

 

not really but there is still sand falling from the truck. lol

 

dam, i think i finally got all mine out. you got a little from in yours tho.

 

looks good....man when i get the money from my taxes next year that is the plan....or i save enought

 

awsome zach whats your RPM at like 45 and at like 60...

i guess its on my list to go before 35s haha

 

about where it was stock

i know 60 is like 2200, idk about 45

 

Yup, I got a 7.5

I don't have enough garage space and my HOA is going to b*tch about me working on my truck. It is a 300 dollar fine and towing of the vehicle.

 

lol that would be funny for them to try to tow it with the axle out of the truck....

you got a gun? if so shoot them son's of a *****s!!!! when they try to fine you and tow your truck....
