Why are Carriage Bolts and Blocks Used to Install Hitch on a 2011 Subaru Outback
Published 06/02/2015
Question:
i have just installed the wiring harness to my 2011 subaru outback and am wondering if i can just ream out the access holes above the holes in the bottom of the frame that i will be using for attaching the hitch since they are already exposed. will using regular bolts instead of using the rectangular units and the carriage bolts be a large problem? thanks,

Expert Reply:
I would recommend you install the hitch on your 2011 Subaru Outback Wagon like the installation instructions recommend.
It would be extremely difficult to use regular bolts with the square spacer block since that would require you to have a wrench on the top of the bolt to prevent it from spinning while torqueing down the fastener. That is why the block and carriage bolt is used.
I attached an install video for you to check out as well.
