New member with a few questions hopefully to be answered. I am not technically advanced as most if not all of you I am sure, but I have 2 problems with my 86 K5 305 automatic Blazer. 1) My transfer case has a crack in it, I believe it is the stock case and I want to replace it with a good quality case, I was wondering if anyone can give me suggestions as to which transfer case I should consider, price is also a factor. I do some offroading mostly on dirt roads and sandy beaches in Mexico so nothing too spectacular. 2) I have automatic locking hubs, and when I switch into 4-wheel drive it does not engage fully and makes a "clicking" noise, as well as not wanting to fully disengage continuing to make the clicking noise until I keep shifting back and forth from 4-hi to 2-hi repeatedly. The shift lever moves to 4-hi and 4-lo with no problem but it seems like the locking hubs are not fully engaging/disengaging. Someone told me it was worn out springs in my hubs but I am not sure. Also is this tough to fix?
