The kingpin locking bolts were so messed up, that there was a massive groove in the middle. Way overdue for an overhaul.

Anyone know why my van blows white smoke only when I'm stopped, and not in "Park?"

Timing-related, definitely.
In park, you aren't putting any load on the engine. In drive, the RPMs drop due to the extra load and the IP has to add more fuel to compensate.

As you increase in RPM, the pressure-based timing advance takes over and adds more advance which stops the white smoke.

I'd be looking at the light load advance cam first off; can you take a picture of how it is oriented?

Thanks. I'll check that out soon.

The kingpins are such a pain in the ***. Finally got all the bushings pressed in. Scheduling the reaming at a local machine shop early next week.

As fat as Kingpins go, i was wondering how difficult it would be to eliminate them all together. They switched to ball joints in the early 90s IIRC.

I hav no idea what all would need to be changed/adapted, i just know that sometimes parts can be swapped year to year for an upgrade. An example is that i have brakes from a '96 SHO on my '94. I was able to use the same calipers, just had to change the caliper brackets, pads and rotors.

Maybe the same concept could be used in our vans.

I couldn't find much on this but these guys talked about it once on the 80's truck subsection: http://www.ford-trucks.com/forums/11...-the-time.html

No matter what, kingpins might be awful to replace, but some people think they are a more durable option. Maybe with a diesel van, which could last longer than many typical ball-joint replacements, sticking with the kingpins is the more logical setup. The only reason why my kingpins were destroyed is because the PO didn't properly lube them. I've been running synthetic just to keep them going for the last 100K, but now the tow-out is so bad that I really worry about our next veggie oil roadtrip in rural Canada.

Interesting thought on the durability issue. I have been greasing mine, and the last time I got an alignment the person said everything was tight. A while back I was looking at wanting to increase my positive caster to keep the van from wandering at hwy speeds. After calling around, nobody had the equipment to bent the I-beams. A couple of body shops said they could do it, but it would be a one off job...which meant $$$. I am going to go ahead and get a steering stabilizer to see if that fixes the wander issue. It isn't that bad and doesn't really bother me, but the wife doesn't like to drive it because it requires too much steering input.....makes it a pain on long trips because we can't trade off driving. Only issue is that the spot that the steering stabilizer mounts to the frame is currently occupied by my trans cooler thermostat. Guess I have to search for another location.

So after you replace the kingpins, do you have a place that will align it?

Im late to the party, but:
man, sucks that you have do that, but way to knock it out! You keep saying "we". Whoever your helper is, is one heck of a guy/gal! That's a lot of work.

I agree entirely with Rob about the white smoke/timing/park thing.

I don't know jack about king pins, sorry I can't help there.

What a chore. Way to knock it out!

My friend from high school. we still do big veggie oil roadtrips every year, so we have to prep the van for our adventures. Don't want to get stranded in the middle of northern canada or the rocky mtns. You can see our trips here: WVO -- Waste Vegetable Oil Fuel Travel and Awareness

It was a lot of work, but since we were so busy, it went fast. My friend left today so I'm on my own, but we got all the big stuff done. I can put the suspension back together after I get the kingpin bushings honed at the machine shop. And I can tune it myself as well. We are pretty thrashed though. I also gotta get the Air Conditioning back together.

I have an alignment shop (Johnson Alignment in Hawthorne) that will do the alignment for me. They suggested I do the kingpins cuz of my wandering problem. I have a steering stabilizer too, so I hope the king pins, the new bushings, the new radius arm stoppers will aide in the tightness.

nicely done .. that was very fast for a van motor swap ..

nonetheless stuffing that big ol idi in there ..

i'm curious about the kingpins .. i must admit i know knothing about em'

or ball joints or what are on my truck .. i think they're ball joints though ..

they're tight though surprisingly .. i can't move em' with the wheel off the ground ..

but there's no grease zerk .. so that's why i can't believe they're still still in good shape ..

my truck doesn't really 'wander' soo much .. but it doesn't self track really and requires constant steering input despite being perfectly alighned ..

it's just a result of zero castor angle on the wheels .. one day i will put a steering stabilizer .. but also one day i will cut and weld the steering to have some appropriate angles ..

it's unfathomable they built the steering straight up and there is practacly no way to easily adjust it .. i guess they sat back and said .. 'mehh .. it's a truck' ..

but they could have easily engineered the steering to steer comfortably .. if they had wanted to ..

The kingpins are only on the econolines up until the early 90's. The van forum on FTE is suffuse with guys complaining about that job. It's genuinely horrible. Good thing I got this spiffy 20-ton press on CL a few weeks ago for $75. Including delivery!

I think all the trucks have ball joints in the 80's by then. I think there is a certain front axle (according to my Ford Trucks Certified Manual) on the F350 4x4's that still has kingpins, but I could be totally wrong. Most of them are ball joints.

Kingpins were a lot more prevalent decades ago. Rat rods got 'em, and all the vids on youtube about kingpin installation are for them, not the econolines. Had I known the econolines were one of the last vestiges of kingpin utilization, I would videoed my install and put it on the web. Could have added to my ad revenue on youtube big time.

But my advice to any van owner wanting to tackle the kingpins.... don't. Pumping down on that kingpin with the 20-ton press maxed out until it finally breaks free and clangs louder than the liberty bell is VERY UNNERVING.

I've transferred my discussion on this thread to here: http://www.ford-trucks.com/forums/14...th-photos.html I added photos and documented my progress.

sweet deal on a press ..

" I think all the trucks have ball joints in the 80's by then "

shweww - that makes my truck hi - tech

" vids on youtube about kingpin installation are for them, not the econolines "

try searching for ' how to do ' brakes - bearings - or seals - on a Dana 70 ..

or rebuilding 4x4 hub .. & prepare to learn all about the 10.25 or ford explorer ..
