King pin removal

Hey folks,

I bought a new set of pins and bushings for the '35 Dodge axle under the '36 "Fordillac" (confused yet?), mainly 'cause I was ordering wheel cyl. kits and didn't have enough $$ spent for a minumum order, and thought I'd put them in yesterday. Wrong.

I pulled the retainer bolt from the axle, popped the dust caps off, and tried several healthy whacks with a BFH and punch. Didn't budge. Then I put a bottle jack under the kingpin boss, used a 1/2 grade 8 bolt as a push pin, jacked the thing up and wailed away on the axle boss with the same BFH, didn't budge.

My feeling is, I'm going to have to pull the axle and press the pins out of the axle. I'm not gonna do this right now, but maybe next fall after the season's over and I have time to tear the front end out of the car. The new kingpin set came with wedge pins, but there doesn't seem to be any in the axle, it's just the set screw, a 3/8 SAE bolt that goes thru the axle boss into the notch in the king pin. It's a blind hole, no corresponding one on the backside.

For now, I thought I'd simply try to slip some shim stock in the spindle boss', upper and lower, to take care of the slop. It's not much, and the steering is tight, so I'm thinking I can get away with this for the summer and what little I'll use the car.

Any other ideas?

Rosebud, then BFG. They wear with notches, and they stick in the pin boss in the axle. Heat the axle evenly to a dull red around the pinboss, then whack away. Let it aircool. Prpoane or mapp gas doesn't work. Cutting torch doesn't work. (no don't cut it, just the heat part)...Rosebud works.

Shims will fall out. Drive it if it isn't too sloppy. I used to have a 63 Econoline van that I used for my carpet installer's work truck. The kingpins were so loose that it had about 1/2 turn slop in the steering...I drove that van for years like that.

Later, mikey

I should have phrased this different. heat with a torch with a rosebud end attached then BFH. As Mikey said do not cut do not use the cutting head use the rosebud. . Cole

I'm a tractor mechanic,, best way i've found..use a bottle jack & socket a little smaller than kingpin,, jack it up ,, a little heat ,,some smacks with BFH..maybe a bigger BFH..IT WILL MOVE..
a grade 8 bolt ..too small unless it's around the same size az kingpin..(try to get even pressure instead of just in center)
the weight of the car,, bus,, tractor,,ect,, being your best tool..
and BE careful not to mushroom top of surface..
I usually take a piece of aluminum and hit on it..
