Kinda an odd one that i really didn't see an old post for. Truck runs good after the tranny rebuild and the tune up, but I noticed an anomaly. After the truck warms up and you drive it, a strange feeling starts.

Say you are at a stop light and you pull your foot off of the brake, but do not hit the accelerator. As the truck moves forward, it feels as if it is notchy, like a cog and gear clunking into each slot. Once you get up to about 3mph, it drives 100 percent normal... no sound, no vibrations, etc... only when coasting forward.

It happens in 2wd, haven't really attempted to shift into 4wd when this happens.

Anyone ever experience anything like this?

 

Could be any number of things. Warped drums/rotors (brakes), bad ujoints, bearings in the rear diff...... Start looking at the easy stuff first.
