Brake Rotor Question

2004 Ranger EDGE 3.0 V6 2WD

I ordered Powerslot Rotors Part #'s 8551PSL & 8551PSR.

When they arrived today, I opened them up and to my surprise they have studs built into them. I expected to see Rotors with holes for the studs to stick through (like on my Mustang).

I have not taken the wheel off the Truck as I was going to have someone else install these. But now I need to know if I got the right Rotors or not.

Can someone tell me if I do indeed have the correct Rotors for the 2004 Ranger?

Thanks.

On my 4x4 the rotor sits on the hub, and the hub is what the lug studs are pressed into. I'd imagine it's the same for a 2wd EDGE, but I can't say for certain.

Like said above the rotors for a 4wd are just rotors not rotor/hubs. Here are my rotors:


For the 2wd trucks the rotor and hub are one piece.

Do you have to replace bearings and everything then when you replace rotors?

Well I would repack the bearings if they needed it but not replace. Unless of course they where torn apart. LOL

OK, I guess I got the right ones for the 2WD 2004 then. They have the studs and the races for the wheel bearings inside and out and a little cooling disc in there too.

I will repack/replace the Bearings at the same time.

I believe the cooling disk you are referring to is the abs tone ring.

Also make sure you torque them correctly. The procedure is in the Haynes manual.

If they look like these, then yes, you got the right ones.

https://www.ranger-forums.com/forum2...ghlight=rotors

You can re-use your existing bearings, but might as well get some newer ones to go along with the newer rotors. Save you from having to go back in there seeing as the bearings are already 5 years old (if they are the originals).
Don't forget to pick up rear seals for the rotors. The first time I replaced the rotors on mine I had everything but the seals. Sure left me scratching my head. LOL

Are you doing this with a friend or taking it to a shop?

Rolldogg,

Thanks for that. Yes those are the ones I got. What about seals? Got a part number or anything?

I am taking it to a local shop for install. Normally they do not install parts they do not supply, but the Mech is good with me as he has done work on my Mustang before and understands that I like quality parts.

I guess I will just tell him to get new Bearings and Seals. The Truck has 80,000 Miles on it.

The races are already pressed in ?
And new bearings didn't come with them ?
That sounds fishy to me as bearings and races are matched together.
Buy new bearings and pop out any races that are already in the rotor assemblies.
Use the races that come with the new bearings.

Seriously if your qualified enough to drive a car/truck, you can change your own brakes.

Thanks for your input.

I never said I couldn't change my own brakes. I can.
I was simply questioning the correct rotors for the job.

Although I am capable, it is not my desire to do it myself. I have the option of doing it myself or paying someone else to do it. I choose the latter in this instance.

Thanks to all that replied with meaningful information!
