Back in 2008 I had a customer bring in his new Backdraft with a noise in the rear of the vehicle. Upon inspecting the vehicle we found that one of the mounting ears for the rear diff housing was broken and the diff had dropped down allowing the axle shaft to ride on the sway bar. Another diff cover (also used) was supplied by the dealer and we made the repairs.
I am a Body Shop Manager and installing used/reman suspension pieces for repairs is not a good practice in my opinion. Especially in a high performance application. Too many unknowns about the part's history - possible prior stress or impact damage, microfractures, ect. can lead to sudden and dangerous consequences.
Here are a couple of photos of the car in question. Not throwing stones here, but please make sure you perform regular and complete inspections of any used/reman pieces, as they are NOT new, as most of the rest of your BDF is.
Please don't misunderstand - I am not saying that you CAN'T use these pieces, but I AM saying that you should pay special attention to them, as their age/mileage/condition is unknown.
