how do i fix my rear end it leaks where the drive line spins.

 

remolve drive shaft remove yoke install new seal put back together

 

pinion seal is bad probly.

 

how go i do that

 

remove the bolts that hold it in a manual will help a lot it has a lot of usefull info to help with problems that will occur

 

II read through my book still cant figure it out on how to change the seal

 

does anyone know how to change a pinion seal

 

step one:remove 4 small bolts that hold driveshaft to rear
step two: pry shaft forward
step three:remove big nut in the middle of where the shaft was bolted
step four:tap yolk off with hammer
step five : pop seal out with big screwdriver
step six: tap new seal in
then reverse steps 4-1

 

if you still have issues you should bring it to someone

 

awesome ill give it a try thanks

 

is it a Dana 35? If so you have a crush sleeve that complicates things a little but it's pretty easy.
If you over torque, or under torque, the pinion nut when putting it back together you can have some issues.
Let me know and I might be able to send you some info

 

good point almost all rears have crush sleaves that set the pressure on the pinion gears...if you crank down real hard you can mess up the setup so once the pinion nut stops don't keep yarding on it , it's a locking nut so it won't back off

 

dont forget our friend red locktite on that pinion nut. If re-using the original of course.

 

yea its a dana 35

 

i have the same problem but in the front. Im guessing its no different. I have a 2000 grand cherokee laredo. Im looking at a jeep oem online store and its saying inner and outer pinion seal? which one do i need for the front? also do i have crush sleeves in mine as well or no?
