Diff breather kit

Post by 98lux »

Santa gave me a diff/gearbox breather kit for xmas,

Will the diff and shock get to hot and melt the hose that came with it? It looks the same as the diff lock hose (hard blue plastic hose)

I have run the hose across the diff from pass side along the brake line and up the shock, Is this a good idea or not?

I did a search on "DIY diff breathers" and I read that you cant have them running along brakelines.
Im planning on building some for the dudelux, using bunnings irrigation hose, hose clamps and some spike things.
If you do a search, youll definately find the info you need.

No...

If your diff gets that hot you have serious issues !

Itll be heat rated hose, but not high temp hose

Keep in mind the shock will compress and extend as your suspension moves.
Its not a bundy!

I had it attached to the body of the shock not the sharft with plenty of slack, but today i reran it straight up and across the engine bay. Now it will not be in the back of my mind all day "is it getting to hot".
Thanks all for the advive.

heat wont be a problem. I have used similar hose on mine.

I also wouldnt run it up the shock. Mine is near the flexible brake line, about the same length as brake line, leave some excess in the line from the diff to the chassis to allow for suspension travel

and what's the issue about not running it along brake lines and is that relating to the hard lines or flexible lines.

Heat from which one affecting which one. I'm using the nylon line similar to that pictured in first thread but not bought as part of a kit. I can't really grasp which one is going to cause harm to which.

My rear runs along the diff to the upper control arm then cable tied along that then over the chassis cross bar and along the body cable tied to the fuel lines up into the engine bay with sufficient slack to allow for articulation. I've looped the slack loosely with a cable tie so it doesn't foul on anything but the loop can pull tighter if needed for length. However the front I have run up the brake line as it is in the perfect spot and I can't really see heat from either affecting either so if it can be explained I would look at changing.

i run all my diff breather/air locker lines strait up on the flex brake line with a little slack. never had a problem. from there i will follow any brake line, fuel line or wiring loom that makes it easiest and keeps the line as high as possible to avoid "snagging".
i dislike attaching to handbrake cables as they are a moving part and are allowed to vibrate by design causing stuff to rub/wear through.

Ive been told by DOT it's illegal to attatch anything to your brake lines, in QLD. Hard or soft wasn't specified so not sure on that one. Just to throw that in..

They are probably just concerned that over time it could rub through the brake line and cause a leak.

because of the hydrocarbon vapours from diff/gearbox oils I would be using fuel hose. Grab 9 metres from a auto shop and a plastic T for the gearbox/transfer case and 3 x Ryco filters to end them at up under the bonnet in the engine bay, nice and high..

The DIY ones I just made have the original diff breathers on a piece of alloy angle between the cab and the tray headboard, I run hose from them to F and R diffs and the diff breathers out of my spares, minus the cap are in the diffs, hose clamp at each end, cable tied out of the way.
All up they cost me $19. Theres some pics on the last page of my build thread in the members section. Ill be doing some for the gearbox and transfer case soon.
