axel bolt size

[Dave_s]

Anyone know what size socket the front axel nut takes on a 97 taursus?

My recall is that it's a 32mm nut. Also, this is a "torque prevailing" nut and should not be reused. The washer behind it may be reused.

If 32mm isn't right, then it is a 36mm. Most chain auto parts stores have a "Loan-a-Tool" program and you may be able to borrow both the 32mm and the 36mm for no cost as long as you return the sockets.

Could it be that mine is non standard? I have the 32 and 36 M and neither one fit (to big).

Also, what does torque prevailing mean? The part stores around here don't cary the nut. Can I pick one up at a hardware store, or is it a different type of nut?

Not necessarily, it could just mean that my memory is not as good as I thought it was. It's been along time since I had the nut off my SHO, and I no longer have it to go check for you. I know I used one of my sockets. I have a 32mm, 36mm, and 1 1/8 inch. Of course, that's off of memory too, I should probably walk out to the garage tonight and verify that as well.

The service manual did not mention the size of that nut, only to replace it what to torque it to.

By "torque prevailing" they mean this nut is only expected to hold the torque one time. As you tighten the nut, it "stretches" a little bit. Years ago, instead of using torque prevailing fasteners cars used castellated nuts for many of the front end and driveline fastening. A simple cotter key would prevent the fastener from backing off. Better design for the consumer, more expensive design for the manufacturer. I think you know who won here.

I appretiate the help. I plan on picking up the 30 mm socket from the local autoparts store that offers loaners. I figure that must be the correct size since it is supposed to be metric (or at least that is what everyone seems to say). Your 1 1/8 would have been very close so It may be that one that you used. I'll let you know whaat happens with it.

I called the dealership to ask about picking up a new axle nut. They told me that they don't cary them becasuse they are reusable. I found that to be interesting since my freind (who is a shop mechanic) tells me that you can reuse them but they are supposed to be replaced (which is concistent with what you are saying).

Turns out its a 30 MM. Thanks for the help!

Sorry for the confusion on the nut size. I checked my toolbox tonight, I have a 30mm and a 32mm. The 30mm has definitely seen more use than the 32mm. I didn't find a 36mm. I'm getting old.

I wonder what the dealer would say if you asked them for a copy of the service manual procedure that states the nuts are reuseable. They'd probably try to charge you for the procedure.

I pulled up the procedure from the Factory Service Manual for a 1997 Ford Taurus. In bold letters, the first note is:
CAUTION: Do not begin this removal procedure unless the following parts are available:

• A new front axle wheel hub retainer assembly.
• A new lower control arm-to-steering knuckle pinch bolt and nut.
• A new driveshaft bearing retainer circlip.

Once removed, these parts must not be reused during assembly. Their torque-holding ability or retention capability is diminished during removal.

If you'd like, I can e-mail you a PDF version of the procedure from the factory Ford service manual. Just Private Message me with an e-mail address that can accept PDF attachments.

That Note was pasted from the procedure to replace the halfshaft on a 1997 Ford Taurus according to the Ford factory service manual.
