Differential leak. Axle? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Celigts · 02-17-2022, 05:27 PM

Lifted my car today…

I’m lowered on coils.
Looks like it’s leaking diff fluid but not from the differential itself.

It’s leaking from both sides.
I’m scared to ask…but what’s it look like?

Just CV boots pissing grease, diff looks dry.

Take axles out, replace boots, cheaps parts but messy.

Yep. A common maintenance item on this car.

Toyota/Subaru sell CV axle boot overhaul kits complete with grease. About $30 each.

Please do this sooner rather than later. If you wait too long and wear the axles out, you'll have to replace the whole axle ($400 each new for OEM)

Any idea on a part number or kit number?

I’m changing dif fluid also. 125k miles and I haven’t changed it once. I feared the worst!

For Differential-side boot kit: Subaru 28497FE021
For Hub-side boot kit: Subaru 28496CA000

Toyota sells them as well, if you're more comfortable dealing with them.

I've done both of my differential-side boots on my car.

It looks like you over lowered the car.

I’m not that low 😂

Well in the pics the axles are pointing UP by a pretty good amount so yeah, I'd say it's too low. Tripod joints like those like to be straight-ish.
