I just completed replacing all the body cushions on my 1996 K1500 extended cab.I searched through most cab mount related posts and if there’s a thread on replacement, I didn’t see it. I also checked YouTube and the videos I saw always seemed to skip over the jacking of cab. Most videos were a waste of time, with issues I don’t have. I kinda remember reading a few years back of someone replacing mounts and using a 4x4 timber when lifting cab or was that being used to tilt bed in a fuel pump replacement.
Anyway, who here has done it? I’m thinking with them all loosened up, what is best jacking procedure? I don’t want to just jack in one area and torque and twist the cab unnecessarily. For instance, do you jack the driver side and then say passenger side? Or, is it a rear cab to front jack. And that doesn’t even account for what’s happening to front of truck with the core support mounts.
First I loosened all 8 nuts, 3 on each side and the 2 under the radiator support.
Then using a 3 foot length of 4"x6" wood timber atop my jack, I carefully lifted up the driver's side of the cab.
I was very careful to avoid pinching or crushing wires, cables, etc.
When the body started lifting, I fully removed the 3 nuts and retainers. I decided to reuse the retainers (think BIG washers), but purchased all new bolts.
After lifting the cab enough to remove the 3 side cusions, I cleaned off all the metal and treated the areas with OSPHO.
After 24 hours of dry time, I sprayed the treated metal with chassis black paint.
Once the areas were completely dry, I installed the top (new) polyurethane cushions and lowered the driver's side fully to compress them.
I then installed the lower cushions and painted retainers and hand tightened the new 12 x 1.25 x 110 mm. grade 8 bolts.
I lowered the jack and timber and followed the same procedure on the passenger side.
After I was satisfied with the 6 side body mounts, I went forward to address the 2 mounts under the radiator support.
