My son's first truck

[dieseldawg142]

the other mechanical prob is a little more involved.
once or twice while in 4lo it would clunk. i thought maybe a bad cv, but after inspecting the cv's, they were pretty solid. then last friday while trucking up this mountain we had a more serious prob. was in 4lo again going up a 30-35 degree gravel hill with a little throttle thrown in and she popped into neutral twice on the hill. little freaky the first time as it started rolling backwards- instantly...
so i'm thinking maybe the shift fork is boogered or the pads are worn off. will also check the "infamous" snap ring on the output shaft


luckily if anything is broken or chewed up, i got this 241 case with 2 yrs of use on it. my buddy bought a 94 k1500 new in '94 and in '97 he blew the t-case. he just made it in under the 3 yr warranty and gm put a new case in for him. two yrs later he blew the tranny and i ended up with the t-case. been sitting in my back yard since '97....wondering what the guts look like after 20+ yrs of non-use...besides his was out of an auto, ours is a manual
