ring and pinion

[grande_guerre]

hey, how do i figure out the ratio and size of my rear diff without taking the cover off(again). 4 teeth are missing almost half of themselves... So replacement will be soon. and whats the average price of replacing one in a shop? i dont have the time or tools to do it myself. thanks for the help.

If it's the original ring & pinion there is an axle code on the safety compliance sticker located on the rear driver door post. ex. 19 = open diff 3.54 H9 = limited slip 3.54, etc.

Cost? don't know.

is it the ring and pinnion missing teeth or the spiders :huh:

in my bronco just the spiders were damaged so thats all i replaced (the 2nd time it blew up on me) (

if it is just the spiders just go to ford and get a spider kit and a new retaining pin for them (the big one and the little one should come in the kit)

should cost no more than $150 and u can do it yourself just take your time and make sure u use locktite on the little pin. :-B

good luck!!

Seabronc those are incorrect gear ratios. 19 and H9 are both 3.55, not 3.54s. Not like it matters though.

oh and the code is h9 and the code for the tranny is K. is that the c-4??

 

[STLKIKN]

GQ, if you have a 3 speed auto its a C-6, they never used the C-4 or C-5 in a full size Bronco.

H9 = Ford 8.8 3.55:1 limited slip 3750 lb load capacity

There should also be a metal tag on one of the rearend bolts that has 3L55 on it.

K = C6 Automatic
