[sm=confused06.gif] I've been trying to get my front rotor off my 2001 Ram 3500 4x4 to no avail. I need to replace the right front ABS speed sensor so removal is a must. I'm getting a little confused after reading all the BB and manual information. Is the unit a single piece molded to the hub or does the rotor seperate from the hub? I've taken out "ALL" the bolts to include the hub bolts. I've used plenty of WD-40 and I still can't get the rotor to budge at all. Am I missing something? Thanks.

the 2001 manual I have says it should slide off once all the bolts are out. Take a rubber mallet and give it a good wack to break it loose.

 

I've used a rubber mallet on it the last two days along with a can of WD-40. The thing doesn't budge at all. Not sure what I should try next?

 

you could try penitrating oil around the outside of the hub where it meets the rotor, let it soak in for a bit. another thing to try is heat, heat up the area near where it meets the hub... just dont go over-board on it...

also call the dealer and see what they say.

 

A trick I learned from the best brake specialist in the area is to use an air hammer with a blunt bit, run it around the wheel studs and all the area in between. have successfully removed a couple stuck rotors that way. Don't forget to put some anti-sieze in between the spindle and rotor when you re-install and it should not happen again, a little on the studs never hurts either. Good luck they can be a pain in the a$$.

 

Gear puller....

Or you can try this. It actually works pretty well.
1) leave the axleshaft nut tight so the bearing won't come apart.
2) remove the 4 hub-to-knuckle bolts from behind.
3) purchase a bolt with the same threading as the hub bolts, but an inch or 2 longer
4) thread that bolt into one of the hub holes several threads.
5) use a heavy metal spacer, such as an impact socket to fill the gap between the bolt head and the end-yoke of the axle tube.
6) start the truck and use the power steering to break loose the hub. Only turn the wheel VERY SLIGHTLY or you will bend/break the bolt.
7) repeat on the other side of the hub.

They can be hard to get off...especially if they have a lot of miles on them...or if they've been driven in road salt. Remember to put some anti-seize on the surfaces when you put it back together.

The rotor is part of the hub. It's a single unit.

 

Thanks for all the good info. I finally got it off yesterday afternoon. I coninued using the WD-40 and rubber mallet. I start the driver side today.....

I always just use a dead blow hammer and beat the living crap out of it. Tourches are your best friend while working on cars too

Make sure yo put some anti-seize on the flat part of the hub when putting them back on. This way they won't stick like that again.

 

glad to hear your moving forward with it... hopefully the other side wont be as difficult.
