Archived Can't get rotors off, stuck in driveway.

[RKrueger]

Hi guys,

I don't know if I'm doing this right, so I have to ask.

on my 99 3500 4x4, I'm replacing the front rotors.

I removed the wheel, and removed the wheel extension, and also removed the caliper.

I sprayed everything up with Kroil, and have been beating the crap out of the rotor hub, but it won't break free.

I see 4 bolts, 9/16, in the rear, next to the knuckle joint.

Am I supposed to remove those also?

Any suggestions?



Thanks,

Robert

yes, do you have a service maunual?

 

[Bob Wagner]

did you remove the hub nut from the axle shaft?

 

[RKrueger]

I removed the center hub nut, but it makes no difference, it doesn't budge.

That's why I thought maybe those 4 bolts in the rear had something to do with this. A garage guy I called said it should pop off the studs, and the new rotor I have in front of me would indicate that.

he said I simply have to beat it with a 5 lb sledge, it's probably rusted.

I've been doing that, but I think I'll have to use a defibrillator if I keep going.

All I have is a Haynes manual, and it sucks.

Is your rotor and hub one assembly? I have my Service Manual in front of me but mine is a 2K which has a separate rotor and hub. Not much help if yours are one piece.

You have to take the four bolts out. It's still hard to remove. You can put a bar between the one of the bolts that is loosened and use your power steering to push the rotor off.

 

[RKrueger]

OK, let me pull those 4 bolts and give it a try.

I'll let you know the results.



My sincere thanks,

Robert

OK, that worked, whew! What a bugger... but after I removed the 4 bolts, I had to drive the studs through, then everything came loose.



One last question: I had to take this gadget out that was held in with an allan screw. It's some kind of electrical device with a wire. It has a little oring around it.

Now that I can look in the hole, I can see gear teeth below. Am I supposed to put grease inside that hole during reassembly?

Robert

that is your ABS sensor and no you don't want to put grease in that hole.

 

[RKrueger]

Well, that was an oops.

I waited awile for an answer, and I put grease in the hole, and put everything back together. I'll have to see if I can get that grease out tomorrow. Oh well...



My thanks to everyone.

Buggers

Rob,



Those rotors on the 99's are indeed a bugger aren't they. Especially for the 3500 with the wheel extensions to boot! Every 00 and up guy has is much easier then we do - they have floating rotors.



Do you still have the owners manual for your 99? When I got my 99 in 5/01, I actually read the darn thing. In the very back of it there was an address and phone number where you could order a real (Non-Haynes or Chilton type) shop manual. If you do any work on your truck you should have the set of these manuals, I think there's 3 in all, the main one, one with specs for body and frame, and I forget the third one - I've always found everthing needed in the main one.



Anyway, PM me know if you need the information to get the manuals - one of the best $100. 00 I've spent on this truck.

Yes, you can grease that hole... it leads directly to the wheel bearings and will not affect the ABS sensor operation...
