IRS Axle nuts.............please read. For all yr Cobra IRS

[ZR]

Just seen the third vehicle have a problem running the OEM nut. What happens, floating washer on the nut breaks into pieces and falls off leaving the nut loose and axle free to float around. Over time, it can eat the hub away until it breaks and or the axle bearing disintegrates. In my case, ate the splines out of the hub leaving the axle free wheeling as if it were broken. Thankfully, Ford has an updated nut, best to change yours before you have an issue.

Updated nut looks similar to this with washer part of the nut itself.

Don't risk damage to your shaft by using bad nuts.

This why you're the good doctor, prevention and cure! Passing this along to a few Cobra buddies, cheap insurance.

The new version is less expensive as well. Retail $7.93 each. Same nut used on the newer Expedition and Navigator IRS, so these should be available for a while.

Good to know. Rick is this a easy install?

[ZR]

Very easy.

[sxy_stang]

I guess I'll be buying these also and having you install them in 2 weeks when the car visits you. I take it that I need 2?

[ZR]

Yes sir.

[WidowrRacing]

Great info Rick....what needs to come apart for this install?
Is it an easy change if doing the IRS brace?

[ZR]

Axle nut off / axle nut on and torqued, just that easy.

Is anyone applying loctite to the nut? Also, what size socket do we need for this bad boy?

[Parkway Ford Lincoln SVT]

These new ones are a Nylok style nut with the insert that provides the locking mechanism, so thread locker should not be needed.

[sxy_stang]

Not too many fords carry them just a FYI. Thanks Ed once again

TTT............just had another one in with a broken washer on the OEM nut.
Update now, yes it can quickly become a safety issue.
