I’ve decided to compile a list of the torque specs for common components on the van as a quick reference guide. If you see anything missing that needs to be added, shout out in the comments!
If you don’t already own a torque wrench and sockets, I use and can advocate for Tekton’s torque wrench (and all their tools in general.) Tekton covers all their tools with a lifetime warranty! Plus Amazon has always been great about returns in my experience.
- 3/8-inch drive torque wrench (I own and use this tool)
- 1/2-inch drive torque wrench (for bolts requiring more than 80 ft. lbs.)
- 1/2-inch drive digital torque wrench (in case you’re feeling fancy)
- Socket set (3/8″ regular or 3/8″ deep; 1/2″ regular or 1/2″ deep)
