King pin reamer

I'm replacing king pins/bushings in a set of 77 f250 sc 2wd front spindles. Does anyone have a proven adjustable reamer for this job I guess? The local shop that will do this is 2 months out and I'd like to move forward with this project a bit faster.
Thanks for any direction that others have had good luck with .

Take the spindles and the pins to a heavy duty truck shop. They will usually do them in a day.

I got mine form Chadwick & Trefethen for my wife's 65. Great customer service and the reamer worked really well.

Were you able to purchase just one? Do you mind sharing what that cost?

I don't know if you want to go this route, but when I replaced the king pins on my f100 I got a appropriate dowel rod and cut a slit in it to put sanding paper in it. As you get closer to the correct size use finer and finer paper. I did it like this and it worked good, just a little time consuming. The dowel rod needs to be long enough to do both the top and bottom at the same time. I will post a picture of the simple set up. I have seen used it for other things too.

Since my 75 F250 is going to need king pins, I too would be interested in knowing the cost of the reamers. Thank you.

I just went through this.I was definitely concerned because it was holding me up and I couldn't do it myself. I couldn't get the old king pins out, I needed them reamed to 7/8" and brass bushings installed for new lowering beams. The tools themselves were several hundreds of dollars. I asked a couple mechanics I know and they had no idea of a local machine shop to take it. I searched and found a one man machine shop. First call no answer ,no luck. Second call he picked up and was nice as can be. He pushed the old pins out, reamed it, installed the new brass bushings(old bushings look plastic) same day. My advice is to keep looking, maybe even a road trip to find a decent shop that will help you. I felt the same way, why does this have to be such a pain in the butt to find a qualified machinist that's good people and will help out? I picked them up yesterday and now I can put the front suspension and steering back in after nerving out over getting this done. Keep looking and maybe a road trip. This shop did everything for $150.00. Brent Epps Machine shop in Gwinnett county Georgia. Hope you find one and get this knocked out.

I bought mine four or five years ago and if memory serves me right, it was $115 then. My local shop also was several months out to do the work, and they wanted $100 anyways. I mis-measured and ended up over-reaming the first pair of bushings, totally my fault. I set it up for the initial cut with dial calipers, not realizing it had 7 blades, not six so I was not measuring the actual full diameter. Don't be me. On the second attempt I set the initial cut by putting the reamer in the bushings and adjusted the tool snug. From there, I cut like 1/2 turn on the adjuster at a time and then dropped to 1/4 turn when I got close and snuck up on it slowly. Those turned out just fine. But now have the tool and know how to use it properly, so I never have to pay to have this done again. The second king pin set, I write off as education expenses.
I'll look when I get home and see if I can find the receipt with the actual cost and model that I bought. Please double check before ordering one for F250's though, as I think they have a bigger king pin and the reamers only work in a fairly narrow range of size.

Found the receipt. The reamer was $118.50 with shipping, but that was in May 2020. I'm sure they have gone up some since then. You can place your order on their website, but they are more set up for dealer with accounts and don't take credit cards on the website. No big deal, I just had to call the number on the order page and give them the card info. They had no issue selling me just one. Super friendly and helpful staff. This is the one that I got.



I also double checked- almost all of the F250s do use a larger kingpin and the reamer I got will be too small for you. If you have the 1.05 kingpin, you will need to order a size H instead of G.
