I have a 97 taco w/ v6 and 5sp. I had to use 4wd the first time this year due to snow, but i noticed a loud clunk when i disengage 4wd. I tried a few times to see if it would go away, but no matter what speed im going it still clunks. It sometimes takes up to 10 seconds for it to come out of 4wd, and i am sure that it didnt do this last winter. I changed the trans and transfer case fluid about a year ago, so that shouldnt be the problem. Any suggestions?
