Oh, apparently there is a save button for changes to that.

Fixed.

Did someone sneak a cable tie onto your driveshaft?

Yeah Nah.

Sneaky idea though.

[Beaver]

Oh heck that's a proper noise. Could be fucked bearings that load up when the brakes are on so make them quiet? Loose driveshaft bolts? Chunk of something in the diff centre?

Weird thing is it goes away sometimes. 

Guess I'll be pulling an axle this week.

[Beaver]

Agreed its weird. And it's not 100% cyclic in the video (a few times it changes speed/double time)

[rusty360]

I had one with my eh, just was a similar noise every now and then, not as bad as yours thou. The axle bearing had started to collapse. Jacked it up sounded ok, but under load not so happy.

[RUNAMUCK]

I'd be afraid it was in deeper.

Almost sounds like a tooth off the ring gear to me. (Part of a tooth)

There's a trick to adjusting the handbrake on those, if it's not returning to its rest stop or if the lever moves a long way

Back the cable off, grab a 13mm spanner, unbolt and remove the lever that operates the handbrake, use the 13mm spanner to turn the 2 flats on the lever shaft until the lever is in the right spot, reassemble 

Spoken like a true Ford guru. super pro tip, you can free up a seized caliper by working it backwards with plenty of CRC until it frees up. Same tactic works on EA-ED. 

Pretty good calipers once you know how to make them work/don't crank up the cable then give up.

On a different note, Electricians of Oldschool, 

Fluorescent lights not working, I have replaced the little starters which has got some working.

The others that weren't working at all now flicker and glow dully at the ends.

Do I need to replace the tubes too? 

 

Thanks.

Yes ideally tubes and starters at the same time

Axle bearing on the noisy side seems fine to me, no damage to rollers and outer race is fine.

Does it make that noise with the axle removed?

I'm not sure I'm keen to run it like that. it's an LSD rear of some sort.

[ajg193]

Sounds like the backlash is just being taken up and released in the diff. It's probably the caliper on the other wheel that is occasionally grabbing as the axle turns. 

Sometimes the piston in the caliper doesn't automatically retract slightly when you let off the pedal, so you will get light rubbing. That can be caused either by internally swollen brake hoses or worn o-ring in piston bore. The o-ring is designed to deform under pressure then pull the piston back a bit when you let off.

 

Light rubbing is always louder than heavy rubbing

They'd filled the oil and ran it in in-store before I picked it up. 

Just got to get rid of the aro fittings for Nitto and might as well run some flex for a dedicated 15a socket so I can finally ditch the mess of multi plugs and ancient short extension cords.

Finally got it in the shed today and turned it on for the first time etc, I'm impressed.

It fills the 70L tank in what feels like half the time the old way more expensive Air Command took to fill 50L! And it does it quieter than the old one ever did.

glad you're happy with it. they are a decent machine for cheap

Oops. I should'a got a bigger boat.

I mean, I don't have that many copies of the PCB design CAD open...
