Got the carrier opened up, nice and clean inside   Found lots of metal in the oil passages for the pinion gears, took a while to wash it all out. Tomorrow i think im going to replumb the brakes on the axle since i last did that back in '05 and the lines are a bit mangled from getting caught up in weeds, sticks, branches etc offroad over the years. Rear driveshaft and anti-wrap bar removed:  ...and the rear is now out:  drive side shaft (yukon 35 spline chromo) is twisted a little:  With the carrier out you can see the carnage:  With the pinion removed you can see the carnage:  Hopefully tomorrow ill get the detroit disassembled and cleaned, and then its just a matter of waiting until next week when it gets rebuilt!  I think i found the source of the fuel leak on the diesel:  The base snapped off the fuel pump when i removed it. Im thinking it was cracked already and leaking fuel into the valley. Obviously i was able to extract the broken portion fairly easily. I didnt get a chance to do much of a test drive though, as the oil dipstick oring in the pan let go, and the motor just hemorrhages oil when its running. So i have a repair kit in the mail, should be here in about a week. Well that was short-lived...  Apparently Dana 70s do break. The pinion got loose, ran deep in the ring gear, and self destructed. So it looks like its getting a rebuild. Passenger side done and installed:   Just a few more things to do, and we're ready to go wheelin! This weather is stupid. The other day it was 72. Today? Snowing.  I finished welding the passenger side slider, got it in primer, and its now in the process of being painted:  Its too wet to really work outside, so i made some changes to the engine tune. Adjusted the VE table slightly, and turned up the priming pulse, which should help with the long crank to start. Im going to have to take it for another test drive once the sliders are done so i can see if it helped any. I also removed the vacuum modulator:  That little setscrew in the top adjusts when the shifts occur, and at what rpm. Screw it in, and it will shift harder and later. The black stripe modulator is supposed to be the firmest, and its also supposed to be what came in the trucks altho with the condition mine is in, who knows! Could very well be original from '89. So i got a new one and slapped it in today:  Fair warming; i didnt know ATF would come pouring out of the hole! Probably should have seen that coming, but i never said i was all that smart! Im not sure if mine was bad or just old & out of adjustment (i have never replaced it, and that trans went in back in 2012 i think), but the shifts are pretty mushy. With the new converter from Broader Performance, and the shiftkit from TransGo i installed during the engine rebuild so youd think it would shift firm but it doesnt at all, so hopefully this will help some. went to the junkyard today looking for random stuff, and stumbled across this jewel:  Somebody put some effort into building this thing:  Full custom-made safari top, with full cage all the way to the a-pillar  not your typical junkyard project welds   yes!  Got the driver side done today, and in a coat of primer. Should be able to get this one painted and ready for install by Monday morning, and then i can start on the passenger side. |
