Hello greeting's from the Pacific Northwest ,Ive got a 77 GMC Camper Special : I have a loud klunk when i shift into any gear . It has a turbo 350 in it and i took the front driveline off thinking it was a worn U-joint . But no . Ive checked the rear ring and pinion and there is very little play there !! So , this is where im stumped . Does the belt in the NP 203 strech ?? making this loud noise???
I can also hear it when im driving . let off the gas a little and it klunks , give it gas again and the same ...
Will it break if it is the belt and take out the whole transfer case ???
Well any input will be appriciated ....
Thanks , Tim
