'Bell' / 'ping' noise when put into reverse

Recently I have been hearing a significant "bell" noise after I start my truck and then put it into gear - specifically reverse.

Also my truck jolts slightly when coming to a stop. I press on the brakes, and just when I'm to a stop it jolts at me, like I'm being tapped from behind.

Not sure if the two are related. The bell noise when putting the truck into gear seems to be a newer / more noticeable issue.

 

The jolt coming to a stop is likely worn leaf springs causing axle wrap.

the bell sound - I’d check your U joints on the driveline for play.

 

It can be your slip joint being worn and needing to be greased (the grease port isn’t very effective, best practice is to pull the joint and apply grease to the splines).

It could also be wear on the flange near the transfer case output:

I has this happen especially in REV. The solution was to replace my U-joints.

 

I third the U joints. After I greased all the zerks the reverse ping and the clunking sometimes nearing a stop went away, as well as some cruising vibration!
