I may have found a source for the washers: Redbarncustoms.net.
I'm going to hopefully call them tomorrow.

I can't seem to find the knuckle to spindle gaskets now either. I'm going to ask red barn when I call. Otherwise, I may just end up using RTV.
There isn't really a gasket for the knuckle to spindle I have seen. I just use rtv. Works fine.

I used RTV as well.

For as much as I feel like I live "too close" to other people, living two blocks from a common auto-parts store is pretty sweet. :grin:

There may very well be a gasket for that location. I just haven't seen one for sale. Rtv works fine though.
Go to NAPA (or Summit Racing) and buy some bulk gasket material. Make your own gaskets. Using an "Exacto" knife and "hole punches" and a small "ball-peen" hammer you can make really intricate gaskets with just a little time.

In the process of doing this job right now.

- no need to remove brakes (as already mentioned). Zip off the 12 nuts holding the backing plate and ring to the knuckle, carefully remove the whole brake assembly and hang it out of the way without stretching the brake hose

- steering arm: after removing the 4 nuts take a 4lb mallet and whack the steering arm side facing to the front of the truck and the side facing to the rear of the truck, near the foremost studs, hard. After three or so whacks, the cone washers let go and the steering arm comes loose; it can be removed by hand. This is by far the superior method to get the steering arm off the king pin bushing plate.

- ball joint/tie rod: don't touch, leave in place. Knuckle comes off with tie rod attached

- inner seal retainer: I found after two hours of frustration that a 3 arm puller with a 4lb soft steel wood splitting wedge across the axle opening for the puller rod to push against worked well. Soldier A had used a generous amount of RTV to glue the seal carrier in place and the slide hammer did not budge it. I whacked the slide hammer until my arm cramped and the attachment broke. With the puller it took under five minutes, once I had figured out which item to place across the axle opening. If you disassemble both sides, you can use a 6ft length of rebar (use the least rusty, crappy one...they also come coated...) from the other side.

- inner axle seal: The upgraded seal (tube seal) from www.rockwelloffroad.com is far superior to the stock design. It comes all set in a new retainer

- knuckle boots: The boots from www.rockwelloffroad.com are tear-resistant and have a slightly increased inner diameter for easier mounting.

(I am not associated with the business but resarched replacement parts and I liked theirs the best)

Before you pack the knuckle with grease (if you so choose) and put the spindle on, it is a good time to grease the king pin zerks and see how the knuckle lifts and centers when you do that (plus, you verify that the grease actually makes it through). After all is assembled, grease the other zerks within reach (pitman arm, spring ends, tie rod ball joint)

I need to go through whole post but I saw something about not having to disassemble else were on the internet so thanks for bringing that up. I skip a head to see the latest info as I'm a bit tired but need to go back tomorrow to look at the rest

One thing that I couldn't seem to find was the torque specification for the 8 bolts that hold the steering to the kingpin(4 top & 4 bottom) maybe I wasn't looking in the right TM or the right spot? So if someone could direct me to where that specification is in the TMs or else ware I would appreciate thanks.

If memory serves, I rolled with the generic spec for grade 8 from the one-pager for bolt torque specs close to the beginning of the TM

Thanks I found the generic spec toward the end of the Tm (page D 2)I forgot they have that page in there. It does tell you toward the beginning of the Tm where that page is so you did get me there so thanks very much:-D

FYI (and for future searchers)... TM 9-2320-361-34, page 10-38: 116-149 lb-ft

A far a the spindle to knuckle agree I just use RTV if you like. As far as the tie rod coming off I just take off one side knuckle with tie rod left on. Then support the knuckle / tie rod to keep it close to level and then remove the other side knuckle / tie rod together. I have tied it up to the spring pack sometimes or if I have a five gallon bucket I just rest the first side knuckle / tie rod on it to keep it level and then do the other side. Then I just lay the whole assembly on the ground so I don't knock it off the bucket.

Great job with this very messy task. I did all 4 of the rears first. Made the fronts a little easier I think. Been there, done that. Wish I had your pics when I did it. I know how much work you went through to do this! Thanks again for the great tutorial!
