Correct way to install new door hinge pin bushings?

[76k5blazerr]

I have new hinge pins and bushings to hopefully cure the sagging doors on my 89 jimmy, curious as to what the correct way to install the new bushings is. I have done them before on a couple trucks but on this one I want to make sure I do it right. After I have removed the old bushings, I know you are supposed to "press" the new bushings into the hinges, what is the preferred way to do this? I have broken them in the past trying to tap them in with a hammer.

I've had a few shatter like glass when I tried tapping them in too..
I ended up hogging the hinge holes out a bit with a dremel tool and a stone,so they went in easier..
I could have tried using a bolt & nut and two sockets,one bigger than the bushing,the other the same size , to press them in,but figured they would just crack like the others..

You could try throwing them in the freezer the night before to shrink them up

ONLY drive in a flanged headed bushing using the face of the bushing that's fully supported underneath the flange by the full press fit diameter of the bushing. Getting outside that diameter and you've attempting to drive that bushing into a tight home only with the week strength of the flange itself. It's going to Crack under the flange where the flange face and press fit diameter is almost every time. Need to drive it straight as possible as well.

Done many. Make sure they are square and should not have problem. If you dremel the hole it kind of defeat s the purpose having the bushing fit loosely.

The bushings I got were Dorman and I did use a bolt with a socket as a driver to tap them in,in the manner shown above..they simply shattered into pieces,not just the flanged part!..

Perhaps the knurling on the bushings were slightly oversized--my hinges had some egg shape to them,but using the dremel to open them up a bit to allow another set of new bushings to go in snug without being sloppy--or breaking again..

One hinge on one of my old trucks,had the hinge holes hogged out oval pretty badly and new bushings just flopped around in them..
I ended up using a drill bit to make them round again,and larger,and I used a "roll pin" 7/16" diameter as a hinge pin on both sides,pressed in using the bolt & nut with washers method..
I couldn't find a decent used hinge in salvage yards,all the drivers side ones were as bad or worse than mine was..

Do you have enough space for a C-clamp and slowly press them in?

Possibly a small c clamp but I would think it wouldn't press them in straight

Yes the holes must be round and free of burrs

I hit the top edge of the hole with a needle file and chamfer the edge. Tap it right in with a little bit of oil on it.

So... how this end up? I'm looking at doing the same with my '79.

I did some bushing and pins on my truck about a month ago. I removed the door, in order to make enough room to get at them. I put a cut out spacer between the top and bottom of the hinge, in order to make sure I did not collapse the hinges while pounding them in with a BFH. I used an angle grinder to cut out the old pins. The old bushings practically fell out because they where so worn out.
