Re: Badly leaking Dana 44, help with R&R of seals!
you got a dana 44 there. I can tell you how to overhaul a C-clip axle but I have never had any experience with a non-c-lip axle. can you find that out and then reply to this. I will be back later and keep checking for your response saying if it is a c-clip or non axle. what the heck let me just describe how to overhaul a c-clip axle and you can apply this information to a non c-clip axle if that what you have. oh and if you have no clue what a c-clip does is it retains the axle except in the case of the axle breaking (I speak from experience of first week of owning my new jeep).
~jack the rear end up by the axle pumpkin then place jackstands under the axle tubes, and remove rear wheels. ~take heavy hammer and bang on rusty brake drum to vibrate it loose. bang it like your torqueing down a wheel on a car with for lug nuts. now remove the drum by pulling and jiggling the drum. you then need to disassemble the brakes (springs, shoes,etc) on the rightside and possibly to remove axles tho I doubt it, but inspect how much brake pad life you have left, oh and check the left outer seal for signs of oil waste 1 whole can of brake clean on your passenger side shoes (if they have lots of life left) and on the drum if that is within maxium diameter spec and is not warped or linings arent in too too bad of shape.
~unbolt rear cover, drain fluid, and scrape all remains of old gasket. use brake clean (different from brake fluid) to make oil less thick and drip better and to get all the metal shavings out if your axle is in bad shape.
Now if its a c-clip axle follow these instruction til I start talking about removing carrier.
~now if its a c-clip axle, turn the driveshaft until the pinion bolt is visible, remove the pinion bolt (like a 5/16's wrench needed) and maybe something else. then push axles into the the housing but be very cafefull not to rotate the axleshafts unless u like to spend an hour and then giving up on putting spider gears back in place. now collect the two C-clips that dropped somewhere in the housing. then pull the axles straight out do not I repeat do not twist or rotate them.
~now if u look at the differential there are 2 bolts on each side of it remove all four of them along with their straps. and some how get the carrier out
~now to the front remove the rear driveshaft from the pinion yoke and zip tie the shaft to the vehicle. dont let it dangle for it wil cause failure to the u-joints
~take an impact gun and unbolt the pinion nut then with a puller remove the yoke from the shaft
~ then remove the pinion. inspect ring and pinion gears for damage.
~remove old seals then replace them. but to insert them correctly into their place without damaging them use a socket for a ratchet that fits over the metal partin the center of it and bang on the socket with a hammer. you want to use a socket b/c it applies even pressure around the seal.
~then replace everything and torque it to spec's, and make sure if there were shims used on the sides of the differential carrier put them where they came from
~use blue rtv when making your new gasket between the diff cover...its cheaper and easier then a gasket but the surfaces must be clean and oil free.
~with wheels on the ground fill axle with oil through the plug in the diff cover.till oil pours out of hole replace cap
~VROOOMMMMMM AWAY!!!!!!!!!!!!!!!!!!! maybe go rockcrawling now
