Ok, I bought my truck and the guy told me it had been regeared, but hes not sure what too:pat: , is there any way to find out what its geared to without taking the whole diff apart? and I wanted to add this in, what do you guys think about motive gears?

Elton

guessing ur truck has a lift ?

The easiest way is to:

For an open differential:
Leave the tranny or transfer case in neutral, lift one of your rear tires off the ground and leave the other on the ground. Mark the driveshaft with a piece of tape or a dab of liquid paper so you can count the revolutions. Get a friend to help you rotate the tire while you lay under the truck and count the number of revolutions the driveshaft makes.

When you get set up, get your friend to rotate the tire exactly 20 times. Count the number of times the driveshaft rotates. Devide the number of driveshaft revolutions by 10 to get your ratio. (If you have 4.100 gears, the driveshaft will rotate 41 times... 41/10=4.1)

For a locked differential:
Leave the tranny or transfer case in neutral, if the rear is locked, lift both rear tires off the ground. Mark the driveshaft with a piece of tape or a dab of liquid paper so you can count the revolutions. Get a friend to help you rotate the tires while you lay under the truck and count the number of revolutions the driveshaft makes.

When you get set up, get your friend to rotate the rear wheels exactly 10 times. Count the number of times the driveshaft rotates. Devide the number of driveshaft revolutions by 10 to get your ratio. (If you have 4.100 gears, the driveshaft will rotate 41 times... 41/10=4.1)

thanks man Ill try it tonight or this weekend

Hopefully he had both the front and the rear regeared to the same ratio, otherwise you'll be binding the driveline while using 4x4 unless you're on sand or slippery surfaces (snow/ice). Might not be a bad idea to check the front too, just so you know.
Good luck.

I know for sure the front and rear are geared the same I've used the 4x4 a few times, but on my manual locking hub, after unlocking it from locked it takes a bit of driving to get the gear inside the switch to come back, what would someone suggest?

GSGALLANT

If you mean it takes a bit of driving before your manual hub will actually disengage your axle after you turn the dial to "unlocked", then you should probably take the hub apart and clean/rebuild it.

yeah I cleand it when I replaced the cv boots, where can I get a cheap rebuild kit?

slosurfer

There is a chance that it either has too much grease or not enough in your manual hubs

Yeah Ill check it out tonight.

Hey, I want to spool the rear and yes I know it chews tires but how much would a regular 4x4 shop put it in for, with no gear change?
