You're right - there's really nothing to show for it externally. I'll have one less drip on the ground and I'll feel much more confident on longer trips. The whole RH side of the chassis was getting misted and splattered by the oil that escaped from the cracked knuckle boot on my longer trips...

With my brother's help I finally decided to tackle the front inner axle seal that I knew was letting gear oil into the hub, wheel bearings, and knuckle boot. I'd been putting this repair off knowing how involved it could be and I made a contraption for removing the seal holder without the use...

Fire departments are known for turning up their engines as performance is more important than longevity for them. Do you know if it ever belonged to a fire department?

I don't have any issues with belts rolling, but I've noticed that on my steering pump (NHC-250) what started out as a matched pair has become 1 tight belt and 1 loose belt and I bet a molded pair would stretch more evenly over time.

I tore into my left rear hub suspecting a leaky wheel cylinder and all I found was two stripped lug studs and a rolled lip on the inner hub seal. Whoever last torqued those nuts & thimbles (army most likely) must have laid on it with a 1" impact because they were on tight! Using impacts with...

Speaking of belts, I've been thinking about going to a banded v-belt instead of a matched pair of singles when I replace my belts again. According to the marketing peoples they're supposed to be better but they could suck to install.

The pioneer tool rack gets populated like this.

To circle back on this blow out i had awhile back, I found the hose on the water manifold to be fully plugged with solid rusty sludge for the 5" of hose closest to the surge tank. I'm thinking this has something to do with the pressure finding a messy way to relieve itself. This was the...

Ok, I'm picking up what you're laying down. My calipers say the new studs match the parttarget.com nominal dimensions for what my NSN should be. The studs (and not just one) must have been replaced before my truck was CARC'd in 2001 because they're painted on the front but are still fresh...

I got some replacement wheel studs (p/n 7409554) for the left rear axle of my M813 from Erik's Military and they're about 1/4" shorter than the originals. Other sites list this same p/n for both the front & rear but they look like maybe they're fronts only? Can I run 2 of the 10 studs 1/4" short?

What an incredible stash of cool stuff. Do they only sell equipment that works or do you not know what your getting?

Wearing a hernia belt while wrestling with those maybe isn't a bad idea...I'll get there someday. The lugs look clean and crisp - are they new (100% tread) ?

Those look amazing! They're twice as wide as the originals 😁

I had similar doubts about their water tightness but now I guess I'm partially following the fording setup. The barbs stopped the seeping at the fill plug but the the middle axle pinion is still leaking pretty bad and I replaced that gasket a year and a half ago. Guess I should have used glue...

I got tired of gear oil seeping out of fill plugs and chunks so I replaced the stock air vents on my M813 axles with brass hose barbs, connected them together with 1/4" hose and tee's and ran the hose up to the breather manifold (but not terminated there yet). The rear axle actually puffed out...

May not relate exactly to a medium/heavy duty setup but those same symptoms happened to my '75 Ford F-250 when 1 of the 3 fingers on the pressure plate that the throw out bearing engages broke off.

I've heard of this happening when the system wasn't able to release pressure via the vent line that exhausts through the front rh side glad hand. The issue i heard of had the hard vent line pinched somewhere near the wheel well. That's something to check on...

I actually drove mine for the first time in 4+ months! Checked the fluids and tires, the engine fired off in about 4 twists, and then cruised down to the truck stop for diesel. Almost scared some bicycles off the road when exercising the jakes. The truck got some stares, some salutes, some...

For now I only drive my truck for fun and maybe put on 200 miles in a year. I wear H-161 headsets while I'm driving so that would seal out a lot of noise.

My 11.00-20 NDT gave out in the same area because the flap was rotted and cracked which let the tube below get pinched into the crack and torn. Would leak 25 psi/hr so I got a new tube & new flap and that became my spare.
