Rear axle leak... Wondering if replacing the rear differential breather will fix the problem

    Just bought a 1999 SR5 4WD with 144K miles on it and the rear axle seals are leaking. I already knew about the issue from my pre purchase inspection but the guy I bought it from stated that it's just an issue with the rear differential breather. He gave me a brand new rear differential breather to install but I'm on the fence on how to tackle the issue.

    Do I bring it to my trusted mechanic to replace the rear axle seals? Do I just replace the rear differential breather? There's a lot of conflicting information on this topic and I can't determine the correct course of action. I'm worried that the rear shoes are already ruined too. Thanks everyone for any help.

    you could always replace the breather and see if it remedies the problem then go from there, breather is easier to replace

    I just had this on my 96, Replaced the Breather and inner seal. seemed to Fix the issue ,But i think just the Breather would of worked. Get the trail gear one.

    If you do replace the seal GET A TOYOTA one! NOT the cheap one. I had mine out and sliped on a autozone one and was almost freefloating on the shaft. Sliped on the toyota one and was a tight fit.

    Thank you so much for the recommendation, I just ordered one. Should I keep the 4runner off the road until I install the new one or should I be okay in the couple of days it'll take to ship? The breather I currently have is shot... The leaking seems to be happening very slowly but I'd rather be safe than sorry and I have a backup vehicle to get to work so garaging the 4runner for a couple day is definitely a possibility.
