I'm doing hub service right now on my A3. I'm using the NAPA high temp high pressure grease with the NGLI 2 rating.

A C-clamp would do the trick!

You just gave me another idea - make a grease reservoir to fill on the small diameter end of the bearing and use some kind of plunger to force the stuff down into the race - pack a whole chunk of the bearing in one go(y)

The M35A3 inner bearings are completely sealed on the larger diameter side and therefore can't be packed from that side without destructive disassembly. They're prepacked by Timken and probably considered completely disposable when following the packing interval in the LO. They still cost...

The TM says the wheel weight is installed after the clamp ring nuts are installed, which isn't how my truck was manufactured. If it were my truck, I'd put the wheel weight on the appropriate clamp ring stud and secure it with another nut. The CTIS stone shield is tightened only to 60-80 ft-lbs...

I don't have a grease needle here - something I need to add to my toolbox. The guy I originally quoted tried a grease needle and it wouldn't fit between the cage and inner race - maybe his grease needle was too big? 🤷‍♂️ If any ESP truck owners want to print this themselves I have the STLs...

This fellow wasn't wrong when he said packing the M35A3's inner wheel bearings in this manner was time-consuming, so I printed a tool to speed up the process. My tool forces grease into the ~1.5 mm gap between the cage and inner race, forcing all the old gunk out from above the rollers and...

There should be an air valve behind the passenger-side rear mudflap. My method of operation: 1) Connect gladhand 2) Open emergency air valve 3) When done using truck air, close emergency air valve 4) Bleed air from connected hose all the way down before removing gladhand Your truck may...

If you want to use compressed air off your deuce the "Emergency" gladhand is your friend! I keep a long air hose in my truck's toolbox with a gladhand on one end and a quick-connect on the other end, to which I usually connect a remote-locking air chuck.

Here's another question: How much does a hub weigh? The OP says a brake drum weighs about 40 lbs. I'm guessing the hub is also around 40 lbs - the hub-drum combo is heavy!!!

I have a rear hub off my A3 for the first time on the account of gear oil coming out of the hollow stud. The outer bearing came out fine and the hub and drum slid off - it's a lot heavier than it looks! Anyway I was hoping the inner bearing would just come out, but it's actually driven in? I...

I'm curious - how could oil get into the cylinders like that? Maybe someone was running it on some kind of oil and created a hydrolock condition? Or someone intentionally filled them with oil in an effort to preserve the motor while it was just sitting? Surely that much oil doesn't just sit...

Wasn't there a way to get them from South Korea or Kia? I thought the improved versions originated with them.

I'm thankful that my truck was titled after being auctioned off to its first private owner - a green AM General pickup ;) I registered the truck as historical and treat it as such.

My floor looked a little bit nicer underneath - just surface rust fortunately! One of these days I'll paint it. I don't take it out much and when I do it's during the summer as my "summer car" so it won't get rusty too fast :) Out of curiosity, what's your truck's S/N?

They supposedly existed according to the parts TM. I attached 10 pages of the parts TM PDF including all parts of the winterization kits. I have no idea how easy-to-find these kits are considering not many A3s were built compared to the rest of the series. I've been lead to believe it's hard...

@fungus glad you got yourself a truck - looks nice! Weird things happen to these trucks whether it's before or after service. My dad's 1953 M37 came home from Fort Drum with three-tone NATO woodland camo. There's evidence it came from the factory with a winch, but it came home winchless with...

That looks sharp! I never thought about using a radiator hose for that. That could be a replacement for the entire duct/hose from the steering assist unit :unsure:

That truck looks like it's almost ready for a scuba dive - just need a longer air intake pipe now!

Once you get the exhaust system squared away you should be able to ride comfortably without hearing protection. It's my understanding that the A3 trucks are a bit quieter than the A2 trucks. My wife and I can have a conversation during a drive, though we still have to speak up - it's not a...
