Decel noise after rear diff bushing install

[mattp_65]

Hello All,
Just need a little confirmation. I am assuming its all drive train noise with all I have installed. So recently I just installed rear diff bushings (Delrin not alum) and now the rear end area is making a loud noise only on Decel and in gear, but no noise while accelerating or not in gear (coasting). I still have stock oem front and rear subframe bushings (changing those out later).
I do have a built jack trans with ACT2600 6-puck solid (chatter of course), poly motor mounts n sway bar bushings, Torque solutions carrier bearing support bushings (Delrin), Energy Suspension rear bushing kit (poly).
Also I have the spare tire delete, so sounds are really amplified.
Carrier bearings are still in good condition, but I dont know about the u-joints.
Whats your thoughts?

Your assumption would be correct! When getting rid of the OEM rubber bushings, you will have more driveline noise coming into the cabin of the vehicle as the delrin bushings don't eliminate as much noise as the rubber bushings did. This is normal for sure!
