The Stovebolt Site Forums The Parking Lot Tons 'o Fun King Pins for a 3800 (what size)

OK I know the methods of removal and I will hone them to size as I have a sunnen here that I can do it with but I found 2 sizes at NAPA.
Is there a way to tell what I need without pulling everything apart first? This is my only transportation and I'd hate to order the wrong parts and discover it only after I had the Axle out of the truck!

Grigg- got a lead on a couple CC axles and am planning the swap for Memorial day weekend!

How about these?
NAPA 262-1161

But no telling if you need oversize pins or not until you remove the old ones and inspect the axle or find you already have oversize ones.

A hint for installing the new bushings is use plenty of Never Seez on the outsides, I put in 3 last night without issue then the 4th galled in the spindle bore really bad, should have used more goop I guess. I was able to remove it and now I'm waiting a week or so for the replacement to arrive.

On your rear axle project, do you plan to swap to single rear wheel drums and make a new backing plate flange to weld to the axle? Don't forget the spring pads need to be moved as well.
I'm getting back to mine soon, just priced those drums at $134 each, a lot more than I had remembered....

OK.. i was afraid of that.
Looks like I'll have to pull the axle and look. They are so far gone that when the front end is off the ground the wheel moves enough to make me think it was a wheel bearing.
I see that you are using 19.5" wheels. were did those come from all I can seem to find is the RV wheels in that size.

I was just going to pick up the axle and then make some decisions. Half the fight is just having the axle in my hands.
DO you think the DRW drums won't fit in the 17" rims? It looks like after I move the spring perch, the swap, pretty much, a bolt on.

My only real concern is do I want the early or late axle? If the only difference is havin to press out the wheel studs to service the brakes, its just a convienience thing and I'm not planning on having to service the rear pads very often...

The single 19.5" wheels I've scrounged here and there.
These folks might have new ones http://www.ricksontruckwheels.com/

The 14 bolt dual wheel drums should fit in a single wheel (most any size) no problem.
The issue is because the springs center measurement is wider than original for the 14 bolt (you're moving the pads out) the u-bolts get mighty close to the backing plates. Might work OK if you use the original 2" springs and keep them to the inside of the shackles.
Might not work so well if you use 2.5" wide springs (from a 1.5 or 2 ton truck) which is my plan because I already have some.
That's why I'm thinking of using the single wheel drums and moving the backing plate, it will also look more normal.

Wouldn't worry about early or late 14 bolt, but given same condition, price, and location, choose the late one.
You'd only need to press the studs out to remove the drum from the hub, which you'd only do if it was worn out. Otherwise to get to the brakes you remove axle and then hub/drum together.

Grigg

You mean more normal from the underside of the truck...
Y'know for all the folks who are lookin there! ;-)

Jeremy

Yep, but sitting so high up and without a rear bumper they'll be pretty noticeable.

So Grigg what is the best way to size new kingpin bushings for a Ton. I got the bushings pressed in fine but the kingpin is too big to fit the bushing. Do you use a wheel cylinder hone on a drill or something with some WD-40?

Best way is to have them honed to size at an automotive machine shop, they can ensure that both bushings have the same centerline (something you can't do with a wheel cylinder hone)

Second best and not far behind is to have them reamed using a reamer that pilots off the second bushing while cutting the first, (and the reverse) again to ensure they share the same centerline.

I've done many of them with a reamer, Lempco made the best ones I've used and over the past several years I've managed to pickup a mostly complete set of reamers with their pilots.
Also had several sets honed at NAPA, they do a fine job.

Alright thanks Griggs. I've got a pretty good machinist here in town at Carquest. I'll get him to hone them to size for me. Thanks again. Sorry for the thread high jack.

Not hijacking.. It's the same topic. I'm doing mine this week!
