I have a 2003 Taurus wagon with DISC brakes and I need to replace the REAR hub bearings is this easy or hard- will this just be replacing a sealed bearing assy or will I need to press on the new bearings.

The parking brake cable might be in the way, but you can get around it.

The main bolt holding te hub on may be strange looking like the attached pics. The are one time use supposedly available from Ford at $14 each. They are called PACNUTS and are made of beveled threaded washers held in a cage to supply constant torque preload as the bearing wears.

Hardest part is getting the brake caliper bracket off, in my opinion.

I know somebody that, when it needed to remove a packnut like that, it took a chiesel and "open it", then tried to unscrew one by one the washers.

Yep, that's single use only.

It is removed just like a normal nut with a normal socket. I did see a post that someone disassembled the nut, which was not necessary.

yes it certainly looks easy and thanks for the info on the pacnut - I bought a chiltons repair manual-and in the manual it has a torque for rear hub/bearing retainer nut for wagon at 190-255 ft-lbs does this sound right ? and dose it got to be a pacnut - at O`Reillys thay sell a regular looking nut-not a pacnut-will this work. thanks

The "locking" can be done in another way. I am not sure what Dorman did for that...
I have used Raybestos and they have a couple of small crimps on the end of the thread - those edges get plastically deformed when torqued and provide locking:

On my 2006 with drums the Ford torque specs was 221ft-ft-lbs.
That's rich! Like any of the torque tools have the capability to measure at 0.5% precision! Because that's what an exact 221 value would imply.
A good, new tool has 3-4%.
We are lucky of we get 10% on regular tools that where used and abused...

Friends I know what the torque is 190-255 ft-lbs what I am trying to find out is what torque you have torqued them too if you have replaced 2003 REAR hub/rearing assy with DISC brakes- to me 190 to 255 is a very large gape- have you torqued them at 190,200,210,220,230,240, or 255 thank for all your help.
