So the truck has been back on the road for a week now and everything seems to be good. I need to get the tires balanced as the bb's just are not doing the trick. So I was initially going to just shim the kingpins and check the wheel bearings to further battle the death wobble that was creeping it's way back into my life. Well when I walked out that morning there was a new puddle on the driveway. The inner axle seal was leaking. At that point I decided to just pull the whole thing and go through it all. Every time I looked at it while it was apart I found something else that needed attention, so in the end I ended up replacing almost everything. This update would go on forever so I'm just going to make lists.
After this project, I will never do business with 4WPW again. They screwed me twice and cost me well over a week worth of down time. I will say that ORD and DrivetrainAmerica.com are now at the top of my call first list. Both ended up sending multiple shipments as I discovered new things. Thanks to imiceman44 for hooking me up with a new set of hangers.
Parts replaced:
-Lower kingpin bearings, seals, caps, bolts.
-Kingpin spring retainers, seals, bolts.
-Wheel bearings
-Carrier bearings. The carrier kicked cock-eyed on me when pulling it out and the races got nicked a little, so I replaced them.
-All hardware but carrier cap bolts and kingpin studs.
-All bushings. Used greasable kits from ORD.
-Inner axle seals. Used the Ford 2 piece seals. Some have complained of issues with them not turning after install. I botched one when putting it in and had to get another, but that was my fault. They actually installed fairly easy and turned well after. I did have to trim the nub off the "sealing goo" to get them in.
-Front spring hangers
Issues found that I think as a collective whole were causing death wobble:
-Spring retainers missing. That's 1/8" of shim that should have been there on top of the kingpin. The old ones must have stuck to the old springs when I did them in Arizona and neither Aaron or I noticed. I replaced those along with adding a washer for another 1/4" under the cap.
-Leaf spring and shackle bushings were Poly, but completely trashed.
-The center pin holding the zero-rates to the spring packs were poking about 1/16-3/32" out of the bottom. This was hitting the spring perches on the axle and not allowing the springs to sit flat, essentially making it a tripod when sitting on the axle. This was probably the biggest issue.
-The inner hole on the driver front hanger was wollered out and appeared to have been for a while.
The truck drives a lot better now. I need to tighten up my steering box a little. Next up is sending units and switching valve on the fuel system. I think I'm going to get a fuel pressure gauge because I have the pump turned all the way up and it just doesn't have the punch it should. Feels like it's running out of fuel so I'm going to put it in between the lift pump and IP. I'm thinking it may be the in tank pump that I'm still running, but that will get taken care of with the new sending units since they are just draw straws.
Sorry didn't take a lot of pics....
