Need help with rear axle breather mod..cant get the new breather threaded

Paulphilly · 10-04-2006, 12:52 AM

LOL, can someone help me (Yes I tried the search function first).? I am trying to complete the axle breather mod that CJ3FLYR was so gracious to introduce. I read his directions, but I cant get the 1/8mpt into the hole. I realize that it is slightly different than the stock POS 1/8 fitting and have read several posts where members state that the new 1/8mpt will have to be forced into the hole and will cause some minor re-threading. But, for the life of me, I cant get the darn thing even started. I am confident that once I get it "biting" enough, I can force it in the rest of the way. After much research and talking to many mechanics, they insist this is a must do mod as it can save our seals from leaking and help our rear diff/axles breath so much better than the oem factory check valve. So, any ideas from those of you that have done this mod? Any help would be appreciated as I am very frustrated

. LOL, thanks!

I had the same problem with mine. I ended up getting a die that fit the factory check valve and re-threading the 1/8" barb about 1/4 to 1/2 way up the threads. Teflon taped' the threads and screwed the thing in. It went right in after I did that. Hope that helped.

Please forgive my ignorance in this matter, but what exactly is a die? Is this something I can get at a hardware store? And, how do i re-thread the 1/8" barb? Thanks

a tap threads a hole, a die theads something to fit in a threaded hole.
tap= nut , die = screw

You can gat a tap at a hardware store to change your threads or posibly go ask a local mechanic if he'd cut the threads for you. Offer him a few dollars for lunch and I'm sure he'll do it. You need to know what size threads are in the hole.

I picked up the correct sized vent tube from toyota. It's large enough so you can use 5/16" tubing, cost about $4 and wasn't in stock. I know nissan makes one but it has a smaller tube and I had already purchased some 5/16" fuel line so I just used toyota's part. Here's the part#(90404-51026) listed as "union".

I'd be a bit concerned of tapping the threads without flushing the the metal shavings out of the rear axle....

He's not tapping the hole in the rear. He's cutting new threads on the piece going into the rear so there aren't any loose shavings.

Right, I definately would NOT tap the rear diff. I re-threaded the fitting going into the rear end. I also kept the check valve incase any warranty issues come up.

links to breather tube and die size? Are the threads fine Metric or course metric?

thanks for the info....

Does anyone know if the stock vent tube is mpt, Bspt, metric??? I ordered a bspt tube that will hopefully be a direct match to my stock tube and will then mate a mpt/barb 1/8" to the bpst fitting. I just hope that the threads are bspt. Any knowledge or thoughts about what type our breather tube is?

Clint · 10-05-2006, 08:16 AM

If you can, remove the check valve and go match it up with a nut that has a known thread size/type and you'll have your answer. Many hardware stores have metrics in stock to use as a size guide.

Good idea Clint. I will do that today and let everyone know for future reference. Thanks
