Hi car gurus,

I was replacing the rotors on my 95 EF Falcon and I can't get the new ones to fit properly. I don't know what I am doing wrong. I followed the intructions in the manual and also from a forum topic. The bearings seem to be not letting them go back. Trying to get the nut back on after the washer, it doesn't go on far enough for the split pin to go in.

I Hope this makes sense.

Any help would be greatly appreciated.

Somethings wrong then dude. You should have heaps of room. make sure you have the bearings in the right way and make sure you have not put an extra metal ring ( cant remember the name of it) on top of the old ones.

Yeah, I know something's wrong. I just don't know what. Everything else went on the same. But the rotor seal doesn't even reach the end, and the rotor just 'flops' off (for want of a better word). I have to hold it on with one hand and try and screw the nut on with the other.

As raven said...make sure you didn't double up on the outer races (or cups, whatever they are called).

I'm assuming you bought new rotors and new bearing kits. Did the rotor have the outer bearing races already in them? If not, did you tap the new ones in that came with the bearings all the way in?

Do you put the larger inner bearing onto the spindle first (small diameter outward), then pushed the rotor on top, slid the smaller outer bearing (smaller diameter inward), washer and then screwed the nut on WHILE rotating the rotor?

You have to make sure that you are rotating the rotor while tightening up the nut so that the cups/bearing seat properly.

So you are replacing the old brake rotors with new rotors?

If so did the new rotors come with "cups" already installed in the rotor hub? If they did, were they all the way in? If you still don't know what I'm talking about. I will take some photos and put them up.

s**t! The single most important thing is the stereo. If the brakes dont work you can still sit in it and listen to the stereo cant you

...I always thought the wheels were more important. I mean without them you can't move in the first place to use the brakes :P

I hope you know Phongus and I are just being smart asses. Yes brakes are EXTREMELY important, but I would have thought when replacing the front hubs the torque setting of the bearings would have to be the hardest part of the job, and thats only because its impossible to get a torque wrench to go as low as 2nm. There has to be something basic wrong with this install and the problem is by the sound of it kallen has already removed the old hubs and now has a car with no front brakes or hubs on it at all..... so taking it now to a mechanic is not possible unless he gets a mobile bloke.

kallen, take the hub/ disk off. remove the bearings from the hubs your trying to install. Check the metal cups that the outer part of the bearings run off. If they are new hub's then make sure that you have not doubled up on the cups. Also make sure the front and rear cups ( pretty much metal rings) are " seated" inside the hub. Place the bearings inside the hub and then carefully slide the hub onto the axle's. You might get them almost perfect just by this, but sometimes it takes a minor amount of force to push it that last little bit in. Also when your doing the nut up make sure you rotate the hub ( like it says in your manual) while tightening the nut. this will help seat the bearing in. Dont worry about making sure you do an exact amount of rotations when turning the hub, just keep turning it while doing up the nut. If you turned it for half a day it wont matter.
