Alright, the bottom kingpin poly bushing defeated me today.

How the hell does one get the spool shaped bushing into the bottom kingpin opening? I almost had it once. There was just about a ¼" of bushing still hung up on the lip but no matter what I tried it would not go into the damn hole.

I tried it with the steel tube in and out. I tried it from both sides. It just does not want to go. Does anyone have the secret to getting it in?

Also, the bushing rim is thicker on one side than the other. What is the correct orientation for it?

As far as orientation is concerned I'll leave that for someone with more knowledge than me.

For fitting the bush I would cut in half and fit the bush in each side of the upright then slide the metal tube in. When the stub axle is bolted up the pressure will hold the two halves in place.
I don't know why SuperPro make their bushes like that but I find it rather annoying.

You can also use a piece of all thread or a long threaded bolt and an assortment of nuts, washers and sockets to push/pull it through the hole.

Ron,

That's how I was doing it but the bushing always hangs up on one side and then squashes to the side.

Hey Ken,
I pressed new busings in all of the front suspension with a low end / cost 20 ton hydraulic press I got from Harbor Freight. Had to come up with some odd pusher / spacers and used red rubber grease on them to help them along.

John,

That was my back up plan that is rapidly gaining strength to becoming the primary plan. I was hoping someone had a 'magic solution' but I guess not.

I'm thinking cutting the bushing shouldn't be a problem with those two giant washers on either side of it once it's installed.

A press is definitely the way to do it. Also for the front leaf spring bushes.

Sometimes you can have luck using an old socket and a bench vise, but it's a bit precarious.

Steve S,

I have a press and used it on the rear springs. Worked out well. The problem with the king pin hole is the angle it's on. It promotes the bushing to squash to the side where it hangs up.

Sockets aren't deep enough. The bushing is quite tall. A piece of 1 ¼" ID pipe might do the trick.

I always cut mine in half. Done this numerous times now without anything adverse happening.

Yah, I watched that video and that's what I was attempting to do. Unfortunately I don't have the hand strength (arthritis) like the guy in the video to pull the bushing straight when it squashes to the side.

I'm going to give the press a couple tries and if that doesn't work I'm going to go medieval on it and chop it in half.

Use a thread rod and nut with washer/s and "pull" it through sigh ratchet and socket. An 8 foot pipe over the ratchet will make it easy on your tired aged adult hands.

Failed to see the previous recommendation about this from Ron etc. eye rolling smiley
