Rear diff breather

[nikos]

i unscrewed the fitting off my rear axle today and it appeared to be a one way valve. does this negate the need for an extended breather, or am i missing the point?

 

[Dave]

Id rather take my chances with the hose up high in the engine bay then seeing if a one way valve work's.

Mud and crud blocks them,you may end up with a leaky diff pinion seal like i did,or axle seals.Throw that thing at someone you don't like and put a hose on.

Has any one tapped the gear box breather to their diff breathers? or should I run another line?

 

[Jason]

I dont think it could be a one way valve, air needs to be able to leave and enter the diff as it heats and cools. If it was one way wouldnt it produce a vacuum when the diff cooled?

 

[Dave]

^ Good point.

Dave.

sorry to ask again but Iam planning on doing this mod this weekend, can I use a tee piece and join the gearbox vent to the diff breather or should I run another line?

Teeing togther is ok.

 

[Ozzy]

Thank you for the quick answer, hopefully wont take to long to get it done

On my 08 the transfer case and gearbox already share the same breather, it is teed just behind the front right wheel. The front diff has its own breather.

Easiest way to do the rear diff that I can see is to install the new connector on the rear diff then run the hose up the left hand side chassis to the transfer case breather and tee into it there.

I ran the breather up into the tub behind the lights, then curled it up under the rail (with a hard back on)

didnt do that, but used it on the end of the fuel hose i ran into the engine bay.

 

[Jason]

Did mine on the weekend, ran the rear diff breather to mid chassis and teed it into the gearbox breather.

 

[Dave]

Bump.

Someone was asking about this earlier today.

Dave.

 

[jimmyo]

ran mine to inside the rear tray with fuel filter as with adding filters to front

 

[Al]

interesting.

i'll have to go double check but my D22 has stock rear diff breather which goes up into the rear chassi.
the front diff, fuel tank and gear box breathers go up into the engine bay. (one of the outlets is top left on jons pic above)

I've checked mine. same as shonky and tweak'e will extend it like shonky described

 

[Al]

guys what size hose should i be buying? 3/16 fuel hose? my best guess from supercheap range. or should i go to enzed

 

[Dave]

Bit late now but I got my hose through Repco I think it was. Cheapest thing I have bought at Ripco.

Time for a bump on this thread me thinks.

Dave.

 

[Kickars2]

both my diff breather's are at the back of the engine bay with mower fuel filter's on the end of them

 

[Dave]

Bump for the new members.

Dave.
