Leaf spring bushing loose, how to replace
I have a play in my leaf spring bushings where it meets the shackle, the leaf springs are from a 3" RC kit and I'm pretty sure they're not poly bushings but OEM style.
my mechanic told me it would take him a while to replace, and in his opinion not worth it for me just for the clunk I hear when turning. So it got me thinking, if it's a matter of time, and on top of that there is no more rust in that area, I can maybe try doing it (i attempted installing the kit previously but it was so rusted I had to give up, so this time everything is relatively clean and would come apart a lot easier) Would I be able to do this myself? I don't have a press or anything like that. can i leave the other end attached to the frame or I should remove the whole spring for ease of replacement? What kind of tools would I need and I guess for the replacement I should go with polyurethan bushings? which ones? cheers |
As you can imagine, there are bunches of ways to remove bushings from leaf springs... as you suggest a press is one way. A 6 ton HF press is your friend. I've heard of drilling holes in the bushing enough so it could be beat out with BFH, or burning them out with a torch. How ever you can remove them is the right way!!

And stick your new ones in the freezer for a couple three hours before sticking them in your leaf eyes, every couple thousandths helps.

I am doing the same thing this weekend. I saw a video on YouTube of a guy drilling them out. Seemed to work pretty well. There is no way I could stomach the smell if I burned them out.
I have a set of Rusty's leaf springs & bought the factory style poly bushings to install. I found out that the ones I have are the smaller, exclusively for Rusty's, bushings. I have a complete set, even includes the shackle bushings. $40 shipped to your door. Attachment 310939 |
I have done it and will NEVER do it again. Complete waste of time and money.
4 bushings.....>>NAPA Chassis was $105.00 and took me more than 8 hours. And still I had worn out springs. By the time the bushings are toast.......so is the spring. |
I did them, it wasn't terrible.
Drilled holes through the rubber bushings till they basically fell out. Pounded the outer bushing sleeves out with a sledge and chisel (this part sucked actually). Froze the new bushings over night then put some grease on them and pressed them in with a regular bench vise. I did make one big mistake though. I installed the spring and put the jeep down on the ground and left it for a few days without torquing the bolts. This causes one of my bushings to crack before I even moved the jeep. So make sure to torque the bolts right after you put the jeep on the ground. |
Thanks for all the suggestions, I'd forgotten about the freezer trick.
What's the torque specs on the springs?

I think so but I also thought that they would work with my springs. They will fit in stock springs.
