Works as advertised. Used on 2004 GX470 differential

Used to extend diff breather on 2001 Toyota Tacoma. Good quality and had zero issues with installation.

Fit perfectly on my rear differential for the breather relocation. Toyota quality and good value for OEM parts. Easy to install.

Fits 4Runner rear differential perfect. Worked for doing the rear differential breather mod

Needed for the breather valve relocation for my 1997 Toyota 4runner 2WD. Build quality is OEM+.

Fits great 5th gen 4runner rear differential. Not a toyota oem part though. Just some no brand item. Put Teflon sealant on the threads

Fits Toyota rear diff to relocate breather

Used Toyota Union - 90404-51319 on Toyota Tacoma Rear Diff relocation. I used Fuel Line 5/16 Inch ID NBR Fuel Line Hose Rubber Push on Fuel Hose for Small Engines 10 Feet, Koehler Enterprises Hose Clamps, Hose Clamp Blister Pack, 4 Piece, Radiator Hose Clamp, Silver, Micro Size 4, Dorman 924-284 Front Differential Vent Breather Compatible with Select Lexus / Toyota Models, 1 Count (Pack of 1), and 1/2" hose clip from Lowe's, and a bolt and a nut I found in my garage... and a few zip ties. I relocated breather to behind tail light assembly on the driver side. The breather is now located at around top edge height of rear wheel well opening so it should be better protected.

Ça fit parfaitement sur le différentiel, j’ai commander le tuyeau et le breather qu’ils conseillent avec et je l’ai remonter dans la boîte du pickup .Je peut descendre mon bateau sans m’inquiéter d’aller plus haut que le différentiel arrière. Une job de 10minutes qui vaut la peine

Very good product, i used it for my trucks rear diff breather.

Perfect fit for a rear diff breather mod on 2nd gen Toyota Tacoma.

Fit well

Fit 2018 tundra rear axle housing for a diff vent relocation. Allows you to connect up a hose to keep you breather well above the waterline.
