Okay so I know I have to replace my rotors becasue the PO said they have been turned a couple times, so with that.

1. I look on line part stores at rotors and some say with "re hub". What are they saying.

2. Do I need to buy a new hub and rotor assy, even if my hubs are fine?

3. Can I sperate the hub and rotor and slide on a new rotor?

I've never owned a 4x4 before so the front end is a big learning curve.

Thanks to this forum I was able to rebuild the front suspension, ball joints, etc...

Thanks for any info Mike

The hub and rotor are held together with the wheel studs.. and rust depending upon how long they have been on there. So you have to remove that assembly, press out the studs and then pry/press the hub out the back of the rotor.

 

The hub and rotor are sold as an assembly and as individual parts.

Buying just the rotor and pressing it on the hub yourself can save you some money.

If you press on a new rotor to the old hub, you stand the chance the rotor will have some run out/wobble.

I purchased new rotors and pressed them on to my old hubs and one of them had run out. When you applied the brakes the front brake caliper would pulse/vibrate bcause the rotor was not true. I took it to a machine shop and they turned the rotor for $20.00. The other side worked fine.

If you purchase the rotor and hub as an assembly they suggest you check for run out and have the rotor turned if needed.

Looking back I should have purchased the assembly. The price difference was less than $20 per assembly. If you don't have a press, buy the assembly.

 

i have the same problem on my 1991 ford f250 drivers side front, replaced the brake rotors and new pads and pressed the hubs on the new rotors and the right side is fine no wobble but the left side wobbles pretty bad when stopping, what should i do? take hub off rotor to have turned or replace the hub and rotor again? im going nuts trying to figure this out! thanks!!!

 

About every rotor I've replaced with new in last 3 yr has needed turned to true up. I put on brake machine first. I've never replace a hub and some of My truck have /had 200000+ . But it happens . I used to just set rotor over hub and use wheel lugs to pull in place tightening each little lug at time. Worked for me. Course now I have alot more toys in the tool department. If worried about it I think the hub/ rotor combo has lugs in it already, which you should probably replace any way. Good luck
