The 4wd worked fine on the truck 6-8 mounths ago, but i stoped wheeling cuase the tranny was going bad and i didnt have secound gear. I didnt want to make the tranny worse. Now i took the l43 out last week and put the l52 in. I modified the output shaft that comes out the transfer case to bolt it up to the tranny. Every thing went together nicely. I was happy to get the new tranny in. ( first time doing something like that ) So right after that i put the truck into 4wd and it makes that noise which it didnt do even with the bad tranny. I stoped wheeling it cuase of the tranny. The front axel is all 1980 stock and it worked great before. I realy want to rebuild the front axel but am not sure if it is out of my skill level. So ive been researching it online to see exactly what needs to be done to rebuild the front axel...
