Hi all, getting a metallic rattling coming from the rear end when I accelerate. Its worse when i get on the gas in a lower RPM. I poked around looking at the driveshaft and its got some play in it. Video included below. I can also push up on the front U-joint and it has a slight amount of give. Is that amount of play normal??

 

Try greasing the front u joints and load up on the rear ujoints.
Play looks normal to me.

eg, No that is likely abnormal play. Your noise could be coming from the catalytic converter heat shield also.

 

I got a loose cat heat shield .

Sounds nothing like a bad u-joint

 

Ujoint Looks badish to me like only one side is gone never really hurts to replace them
