    Re: pinion bearing replacement

    You would need to disassemble the whole diff to get to these bearings. In a nut shell, axles out, carrier out, pinion nut out, then pound the pinion gear out. My suggestion is to do it with the diff off the truck. What made you think your pinion bearings need to be replaced? If they are worn, your gears are probably toast. Good luck.

    I agree with 68SS here, if your bearings are done then you need to examine your gear set. More than likely they have now worn improperly and wont set up right ever again or will be very noisey.

    Doing this repair isnt for the novice in my opinion. You need to have a good understanding of what is going on inside a differential in order to be successful at setting up gears. There is a lot to potentially screw up!

    Re: pinion bearing replacement

    but if u do wanna try it this is what has to happen, Remove drive shaft and diff cover. remove your brake drums(ordiscs and calipers if equipped. Rotate carrier until you see an 8mm headed bolt and remove it with a wrench and be ready for the large pin to come out. Now you have to push both axles in and with a magnet remove the c clips. Now u can remove your axles. next remove your carrier caps and dont mix up what side they go on and what direction you face. when you remove the carrier keep all your shims on the same side they go these determine your gear backlash and bearing spread. Now remove your pinin nut and pinion and yoke .Sometimes the yoke is stuckk and needs a puller. Next remove the pinion seal and then you can get the rear bearing.Remove the pinion. The other bearing on your pinion has a shim under it and will need to be removed and reused if u dont plan on remeasuring your pinion depth with a gauge block and dial indicator. Now is a good time to check your gears for wear. Once shim and new bearing and new crush collar are on install pinion in housing and intall rear bearing and new seal. install flange and nut tighten nut to 13 inch pounds of rotational torque. If u exceed more than 20 u gotta replace crush collar. Your gonna need a breaker bar for this and keep checking your torque. After your depth and preload are set re install carrie and shims torque cap nuts install axles and paint gears to see contact pattern. If you have a dial indicator set up on ring gear tooth and hold pinion and check backlash that is the play between gears you want ten thousandths or close. It seems hard but once u get into it its not to bad hope that explains what invloved wish i had some pics for ya
