Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF

ok... progress turned into 20 steps backwards today... got the dana 70 front axle install done only to find out the truck had only been driving as a front wheel drive since I bought it apartently. it has a th350, np203, and had a old dana 44hd that did not have lockouts. so it was a full time 4x4. when I put the 60hd/70 in it I of coarse unlocked the hubs as I could now drive it as a kinda 2wd until I needed the front axle locked in. it just sat there in its tracks and would not move. apparently the 203 is toast. only sends power to the front wheels. so I relocked the hubs back in and it moved again. but it would only go straight. try to turn it and the power steering pump would go nuts. the front 60hd/70 does have a locker in it. so im going to have to put ram assist on it now. and to make matters worse the 60hd/70 needs new kingpins and bushings.... ugh.
