rear driveshaft lubing

[looking4lc]

lately, I feel something is shifting in back after lubing the driveshaft (rear end) which I believe first time lubing cuz I didn't know there was one needed lubed in the vary back. usually I lube the zirks and driveshaft (front one and middle).

when I go over a speed bump and accelerate, I feel like the whole differential is moving.

I wonder if it is because 1st time lubing the rear driveshaft and this is normal or something else

I know I am not descripting it right but this is what I could say about it

care to take a guess? open to all suggestions

Thanks

There are 3 zerk fittings each on the front and rear driveshafts. 1 on each u-joint and 1 on each slip joint. If that's the lubing you are referring to, you might want to read the driveshaft thunk-clunk threads to get some ideas?

I need to spend more time under the truck and find all the zerk fittings.

The Official clunk/thunk drive shaft thread - good reading.
