trailing arm bushings - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What level of effort is required to change these on a 1/2 ton long bed?

Remove the arm and clamp it into a vice. Then, run them out with an air hammer and flat bit.

Getting the big bolt out to remove the arm is the hardest part.

A fair bit, the sleeve for the bushing in stuck in the arm real good, and the rubber is stuck in the sleeve even better. What I always end up doing is basically setting the rubber on fire with a cutting torch until it shrinks enough to slide out, by that time the arm is good and hot so it will help getting the sleeve out but sometimes I still have to cut it in half and work it out. BTW you can get the bushings from your local GM dealer still.

I Usually Just Take My Trailing Arms & New Bushings Down To My Local Driveline Shop. He Presses My Old Ones Out, & My New Ones In In About 3 Minutes. I Buy Him A 12 Pack, & Were Both Happy.

I took mine, turned them on their side, and burned them out with a propane torch. Once the arm was cooled I cleaned it up with some brake cleaner, put some lube in there, and drove in the new ones.

I have set fire to them as well before and it works fine. However, the last time I did this I had just parted out a truck and my torches were out of gas

. I simply took a small drill bit in the cordless drill and drilled through the rubber on the outside edge a couple times and hammered them out. It wasn't as cool as setting them on fire but it worked. Just my .02

i second the pyro technique. then you get to upgrade to poly bushings by using the existing shells.
