What is it?

Anonymous · Post by **Anonymous** » Sat Jun 10, 06 7:15 pm

Can anyone id my axle for me please? I need wheel bearings and have no idea what I'm running. The typed "history" sheet that seems to have come from the US tells me one thing but I'm not sure.

Thanks in advance

The casing will be stamped on the side.e.g 741, 742 etc..(8 3/4" type)

8 3/4, you need to check the numbers on he drivers side of the diff behind the pinion yolke for the casing type, 741/2 or 489.

HTH

as it says in the info that MilesnMiles put the link to (same as this one http://www.autohobbydigest.com/8_75.html ) the i.d. to look for is a large 'X' for the 'smaller' 741 casing (it also says ----741), a large '2' for the more desireable 742, or a large 9 for the favoured 489.

The pic below shows our Polara's wimpish 741 - note the 'X' and the smaller ----741 markings.
Our Satellite's got a 489 but I havent got a pic of it or its markings, sorry. But I do know it has the large 9 on it.

It's hard to see what it is Steve. At first glance i would say it is an 8 3/4

But if you were told it is a 9" Ford, - well perhaps it could be. The 9" Ford is a 'pumpkin' type axle too. We'd need a few more pictures, but there must be some identifying marks on it somewhere.

Post '67 9inch axles usually have a 'hump' in the middle of the rear 'cover', as though it 'surrounds' the ring.

Pre '67 9inch axles don't have this, but are more rare. Ford 8inch axles don't have the 'hump' either.

So I guess this makes it a 489... whatever that means. Anybody what to try for a lay-mans explanation please??

It means you got the prefered model of 8 3/4 axle
