Hi All - 1st time on the forum
I am currently servicing the front dana 44-3f on my 68 w200. The passenger side u-joint grenaded, so that knuckle is apart. The outer axle shaft is toast, so the local ADCO drive line shop is hunting that down for me. The external diagnostic was steering wheel range of motion was reduced from 6 turns stop to stop to 3. The broken crosses on the u-join fell into the bottom of the knuckle, prevent the knuckle from turning all the way. I was lucky to keep the truck on the road.
The passenger side lower knuckle bearing took a hit from the grenade. I was wondering if anyone here has service the lower beating cone and what technique did you use. If you have serviced the upper bronze, I would be interested in that also, plus any parts source you may have found, especially the big spit seal and felt on the back of the knuckle. The cones actually "look" ok, but if easy changed, might as well do it now.
I also pulled the differential to service the axel seals adjacent to the diff, where the drivers side was leaking badly. The axle shaft had a stain on it where the oil was getting by, which the ADCO guy pointed out to me, and told me how to pull the diff. The diff pulled out easily with a crow bar center on the spider gear carrier and a nudge on the bar and it popped out, so no case spreader was needed. The seals went in ok, using two extra long extensions on a socket, driving the seal through the opposite axle tube, after starting them with the same socket, and a plastic hammer, being careful to not touch the diff bearing races. The new seals intergrate the guides so you have to remove them. I just pried out the oils seals using a seal pry tool, and the guides worked loose via finger pressure, but a long wood closet pole (perfect size actually) helped loosen one side it by driving it from the knuckle side.
The diff looks to be great shape, with a very nice contact pattern, after all these years BTW.
Any experience and advice appreciated, as this is the first time I've had to do a complete tear down on an axle.
