I don't see anything in that picture that would be making that sound. I haven't opened my air cleaner yet, so I'm assuming it's just an empty canister when there's no filter in it. It goes right to the turbo, so I'm thinking it's a turbo-related noise. But then again, those noises usually...

That doesn't sound normal to me. I hope i never hear that sound on my A3! LOL

I might have the answers for a couple things: 5) Bad steering box seal perhaps. They do contain oil despite not being powered. I don't know if they can be rebuilt or what a replacement costs. 6) I'm guessing a bad 1st gear bearing. My dad's M37 knocked in 3rd gear and it was a bad bearing...

I'm not familiar with how powered hydraulic brakes work. Do they rely on a hydraulic pump, like the power steering pump?

I was in contact with a guy who can 3D print metal automotive parts, including brake components. He actually specializes in antique car restoration. Perhaps if there's enough interest here we should engage him?

I wouldn't do over 45 MPH in any of my trucks no matter the age, unless it was a HMMWV. I'd just enjoy going "slow". After all, it gets more looks that way as it's a lot harder to get a good look at a speeding bullet of a car :p

All the 5-tons from the M39 onward have power steering stock, but also had an air-assisted hydraulic brake system like the M44 deuces. It wasn't until the M939 5-tons that full air brakes came stock. That truck looks like an M51 5-ton dump with an air brakes mod. It makes me wonder if it...

I live in a rural area myself. I might pay the local tractor tire service to come to my place and do the hard parts. Haven't decided yet.

When I pull my wheels apart, I'm going to clean them, paint them, and replace all the seals, possibly the tire stems and turret valves as well. These combat rims seem to have two main failure points: the valve stem grommet, and the o-ring between the rim halves. Properly installing the seals...

Here is the parts diagram and parts list. I'm sure some vendors on here have what we're looking for (I'm going to do this myself next year).

Nice combo you have there! That price is consistent with what I've seen for trucks like yours, although the trailer is a huge bonus!

Yes, there is a priority valve in A3 air systems to reserve air for brakes. If you haven't found the TMs yet, you can find them on Jatonka's site. I don't think there are A3 TMs on SS yet for some reason.

Welcome to the A3 club! In my experience, the air-assisted steering cylinder will suck a lot of air with a lot of back and forth steering movement, like when parking in a tight spot, to the point that my air buzzer will sound. I believe that is normal behavior. My truck is a 1995 and I haven't...

Welcome! And you have a pretty rare truck in an M36A3! I think you should start another topic and post pics :cool: The locking transmissions eliminate losses between the engine and transmission through the fluid coupling (torque converter) in 3rd and 4th gear, increasing fuel efficiency. In...

I thought you could fit a HMMWV in a deuce... It's just a bit tight, right? :LOL:

Yeah, that sounds like a voltage problem! An auto electrical shop should be able to help you out. My dad took a pair of generators out of M37s to the local guy, and they were perfectly rebuilt.

I considered that, but the sound was coming from the front of the truck so at first I thought it was the compressor. I was checking my air gauge while on the move and didn't see anything weird happening. It seems based on the feedback so far that the tire needs to be replaced due to a...

Tires are cheap - lives aren't! And lawyers and fines and parts etc.

That makes a ton of sense! I was hoping to get to the end of the year with these tires, but it seems that I'll be replacing some before the winter, especially on the steering axle! I'll check that (from a safe distance) but I bet you're right.

These are awesome finds! So the one FMTV available for sale (or was) is diesel-electric?
