Ok so basically, randomly occurring binding action at 35-45 mph, (this is just the speed I happened to be going when this happened). Has happened twice. Been driving regularly I'd say 150 miles a week, city and everything else.
This action is front end orientated, been looking into the np249 I have in this gal. Seems like this may be the culprite. ..

Further description: driving down the road and all of a sudden> bind..cease..wobble effect. Though it doesn't last long since I immediately put her in neutral. Then when (while still coasting) put her back in drive, she well...drives normally. I have 75 w 140 in the transfer as specified. Recently changed and fresh as well..a week ago.
I do experience slight jolt and binding in sharp turns while at low speed...though this even is random. So I'm supposing a coupler is going out.

Am I right, slap me with understanding please.
?
Thanks.
