transfer case ?? experts help!!

I am new to the 4x4 scene. I recently got a 72 K20. The last few times I put it in 4 low, the transfer case shifter sticks. I have to straddle it and jerk as hard as I can with both hands to get it out of 4 low. I'm afraid I'm going to break something. What's going on?? Thanks for any help.

Straight cut gears and still a little bit of drive line bind on them. Tranny in Neutral, slight grade. Roll a little when your shifting and it usualy shifts fairly easy then.

Just make sure it's in a gear before you put the tranny back in gear. If the case gets into N and the tranny (auto) back into gear you will probably have to shut the truck off and let the transmission stop spinning to get the case back in a gear.

Another thought for you if the above doesnt work..... If it is a NP 203 case, the shift linkage comes loose an makes it a PITA to shift or get into/out of a gear. You might crawl underneath and check to see that the linkage is properly adjusted/tightened and is on the case correctly....

A 203 shouldn't be in a '72, but it might be the bushing in the actual transfer case to transmission adapter, that the lever fits into. they tend to go bad after being 33 years old and not being replaced.

The linkages have a plastic/nylon bushing that goes bad sometimes. I have found those in the help section and they actually had some from B&M in the hot rods stuff at PepBoys when I needed one.
