BroncMom Added deer whistlers under the front bumper. Couple close calls with NwPa's whitetail population was enough for me.

bmad01 I filled up the 88 this morning. 207.7 mi. and 15.229 gal. = 13.638 MPG! The old guy's still got it! Any time I'm not getting 11 mpg is good!

What did you do to your bronco today?

Replacing my 4 bolt F250 steering box since the pinion shaft seal blew out on me in the middle of a rock strewn twitch trail. Driving out through the boulders with no power steering was interesting. Watch those fingers in the wheel!

You absolutely can re-use a pinion yoke, if it's in good/acceptable condition. Most used pinion yokes will have heat-affected-zones on the spline hub in the locations where the pinion oil seal contacts. This is typical. However, once those H.A.Z.'s wear to the point where they are physically scored into the hub surface your options are to replace the yoke entirely, or purchase and install a repair kit. The repair kit is little more than a very thin sleeve that slips over the spline hub to, in effect, create a new surface for the oil seal to ride on. However, since both items cost very nearly the same (~$50) it's a better practice to just replace the yoke.

You can tell if you have scoring/galling on any smooth metal bearing/seal surface by using your fingernail, which is highly enervated, to drag across the surface. If your fingernail detects an imperfection the surface is to be considered compromised. This technique applies to bearing races and the individual rollers in cone bearings as well.

You can help prolong the life the of pinion oil seal and the spline hub itself by using a high quality/high drop-point bearing grease to thoroughly coat the seal's contacting rubber surface prior to installing the yoke. The grease will, ideally, get trapped in the small voids created by the seal's multiple ridges, as it has nowhere else to displace to, and provide a constant source of lubrication throughout its service life. A lot of guys tell you to just use the same gear lube as you're using for your diff to lubricate the seal, but the builder who taught me used to say, "Fluid is designed to flow and grease is designed to stay." Also, it won't hurt a single thing if a small amount of grease, from coating the seal, gets mixed into the gear lube over time from mild seepage.

I knew all this, going into my build, and every axle I've built for customers always gets a brand new yoke, but I cheaped-out on my own rig and she let me know she was pi$$ed.

I said the same thing about my rig 3-days before the tranny filter popped out.

cobrajoe Started putting mine back together after taking a week off from working on it, only to get aggravated. So went home and cut my lawn.

NASSTY I adjusted my steering stops. My tires already rubbed the radius arms pretty bad. I recently swapped wheels to some stock steelies and they rubbed even more.
The steering stops were rusty as hell. I had to use a little heat to loosen them so I didn't snap them off. Maine winters have not been kind to the old girl. Then I realized that if you extend them very much there is only a few threads holding them. So I went to the hardware store and got some longer grade 8 bolts and cheap nuts and made my own. Now I have almost an inch of threads holding and no more rubbing.

Now I gotta work on my inop tailgate window.
I probably won't last a half hour on that project before I get mad and go take a nap. .

If the seat for the seal is not damaged or gauged like I think he said his was you can re use them. A gouge or but will shred/melt the seal eventually and cause a leak.

I knew better, but did it anyway to save a buck. It had scoring on the spline hub from the pinion seal wearing into it over the years and I hadn't noticed. I thought they were just discoloration from heat (fairly typical in used yokes) when I cleaned it up for the build and didn't bother checking with my fingernail. That's what my "whistle" was. It was the yoke seal riding in those grooves. Now I need to find a new yoke available locally. Pretty sure it's still not a "parts store" item. I've always had to order them from somewhere in the past.

BigBlue 94 Thought about driving it...

But the broken lockout, worn axle stubs, open header, sticky throttle, and cobbled together driveshaft changed my mind

MS88Bronc Hit the MOAP (mother of all potholes) yesterday and my CEL lit up. Ugh. Wtf.

cobrajoe You can always put a Speedi-Sleeve over it.

bmad01 Took the day off work because I can and still get paid! Anyhow I had an appointment at Auto Interiors Plus. Drove the 93 down there @ 8:00 AM to have them repair the drivers seat. It seems sliding in and out of a lifted truck and dragging my ass across the side of the leather seat had taken it's toll. A tear was starting to get ugly and I figured it was time to do something about it. Rich had it done around 2:00 pm and called me. I went back down there and $275.00 later I was on my way. I now need to practice getting out by putting a foot on the nerf bar to lift up my dead ass off the seat getting out!

Flint Getting the 302 dropped in until my 351w is finished at the machine shop. So far so good. Turns out the 302 is out of an 87 and had been FI so it's being returned to the purer faith.
