Back left driver wheel 2002 tundra 4.7 sr5

Hello i noticed a leak like a seal. Wonder if anyone would estimate what part numbers i need to replace what the problem is for this leak? Thank you

 

Rear axel seal? Wheel cylinder? Brake line?

Pull the wheel and look!

 

No brake fluid loss in the master cylinder? If not, looks like an axle seal blew probably. I went through this myself... Check the axle breather to make sure it's not clogged. You're going to want to replace the wheel bearing too since it's been soaked in gear oil. The bearing has to be pressed on, a machine shop can do that if you don't have the correct tools.

Here's the parts I used.

90363-40068 - Wheel Bearing
90313-54001 - Outer axle seal
90301-88077 - Axle housing O-Ring
90310-50006 - Inner axle seal

This is the axle breather, twist it around and make sure there is no crud in there.

 

If it’s the left rear wheel cylinder, the part number should be 47570-06051 for around $76+.

 

Thank you for the info

 

If axle breather clogged then what?
Thanks

 

If the axle breather is clogged and the axle heats up from driving, the axle will try to breathe through the path of least resistance, which is the axle seals.

 

My guess is axle seal. Need a press to replace. Recommend relocate the breather into your left taillight housing easy to do with nipple, hose and breather or can buy a kit for this.

 

I had this happen to me too, I don't know why people are talking about presses and bearings, its just a normal oil seal. No big deal to replace.

You probably do want to do a brake job though while you're at it if any of the oil got on your brake pads.

 

The axle breather turns freely. I can twist it back and forth easilu

 

Take pics of the carnage if you can once the brake drum is off.
