I have a 99 T800 that i would like to change my spring pins/bushings in. I have press, torch, air hammer and all the other tools i should need to do this. I have no experience with this but usually catch on pretty quick and i'm fairly mechanichly inclined. Truck is not doing anything right now and i have the time and like to learn how to do new things. Where do i start on this? Does the whole spring come out and shackle hangers as well? Are the pins threaded? With almost 1 million miles on the truck should i think about replacing the springs? Any special type of pin/bushing i should replace with? Talked to a local spring shop and sounds like they should have everything i need. New springs are $490 a side through them so i was hoping i didnt have to replace the old spring.
Thanks for any advice/help you can give me.

If you can rent a tiger tool pin bushing puller/installer it makes this job a breeze, it will do rubber isolated, threaded and straight pins with the proper adaptor kit, 4 min vid to show how slick it works

I'm not sure if they do it for the threaded kw pins and bushes as they generaly are pretty good .but I use the Horton needle roller replacement kits on the Pete's they seem to be better than the straight brass bush and pins the Pete's have.
any one else used them? -

So if i am gonna start on this and kinda learn as i go, where/how do i start?

Unless your press is specifically for this job, either get a proper tool or hire someone to do it. Me and the old man are pretty mechanically competent, but we didn't have the right tools and it took us 8+ hours to do one pin/bushing.

Start with placing a bottle jack between the spring and frame about a foot from the rear pin, jack up till the weight is off the pins then remove the shackles, might want to mark them if they are the "s" type, the oem pins and bushings are threaded and the bushings are tack welded into the spring eye, I cut the weld around the bushing on the out board side only with a 3" cutoff wheel, then thread in the old pin half way and pound it through with a BFH, if the pin and bushing aren't to worn it should move the bushing out of the spring, we have a new pin welded to a 4 foot pipe so we can use big hammer and not be under the truck, knocks them out quick.
the top bushing on the frame I unbolt and take it to the press, push out old and install new, easy.
To install bushing into spring, clean eye out so new tack weld has good metal, thread new bush onto pin that is on pipe and pound it in, if using one of your new pins use care not to mushroom the end or the shackle won't fit. push bushing in till flush, make sure pin will turn easy in bushing, then tack weld it in. thread in the pins and put on the shackles, may need adjusting to even out the secure the bolts.
on a good day take about 4 hours to do the rear pins and bushings on both sides, on pins that are siezed in the bushing sometimes you can beat both out together, rarely remove the spring, front pin and bush done the same way, jack, beat, repeat. kind of a quick run through, hope it helps.w9l and logtrucker25 Thank this. -
I cut the old ones out, clean the bore real good with a round file. Then I never-seize the outside of the bushing and use a 1/2" threaded rod and the washers from the Pete low airleaf bushings. Just put a nut on each end of the rod and tighten them in. I can do it all on the truck and never hit anything so that I don't mess anything up.
