How to Install a Body Mount Kit Like a Pro
In vehicles with a body-on-frame construction, the bed and body of the car are mounted on top of a rigid frame where the engine, suspension, and transmission components are attached to. Commonly used in trucks and old vehicle models, this construction has an important in-between component that makes the bed comfortably sitting on top of the said frame-the body mount. In case you need to raise your vehicle a little for more road clearance, you need a clear guide to instruct you with the installation of these body mounts or lifts. This task needs a good hour of your DIY time.

Needed tools and materials
Taking the measurements
With the tape measure, determine the distance between the bottom of the cab's rocker or sill and the frame. Take the measurements in different places to find out if the distances are even or not. Then, measure the distance between the cab and the ground. Write these numbers down; these measurements will help you make the right adjustments when you install the body mount kit.
Unbolting the mounts to be replaced
Find the location of the body mounts. These are located underneath the core support in front of the vehicle; two are on the side underneath the cab. Use the 1/2-inch ratchet and socket to unbolt the body mounts.
Placing the wood block and lifting the cab
With the wood block placed on the jack, position the jack next to the part of the cab where a new body mount is to be installed. Crank the jack until the wood block touches the cab's rocker. Crank further until there is a one-inch clearance between the bottom of the cab and the top of the old body mount.
Replacing the body mount
Swap the old body mount with the new one. After sliding the new body mount in, loosely thread the bolt into the mount so that the part will not be out of alignment when you work on the next mount. Once done, fasten the bolts of the mounts on that side, then repeat the same process on the other side of the cab.
Checking for fitment and alignment
Check the alignment of the cab in all directions. If one of the mounts is out of alignment, loosen the said body mount and adjust the cab's alignment whether by pushing or pulling a centimeter or two. Once the measurements match the ones recorded, fasten all of the bolts of the cab.
Tips and warnings
- When you jack-lift the cab, check if the gap between the fender and the door closes. If this happens, remove the hood and fenders first before cranking in order to prevent damaging these front components.
