Hey Guys,

I recently put new rear calipers on to my 66 and within about 50 miles of driving my driver side wheel started to wobble. I pulled the wheel off and took a look at the rotor and noticed that there has been a grove cut into as well as the fact that when I grab hold of the rotor I can wobble it in all directions. Would it be possible that what every holds the rotor on is loose? I don't think that it is the camber as it can be moved in all directions.

Also, if anyone has an extra rear rotor to sell please let me know as I am guessing that this is going to need to be replaced.

Thanks in advance for all the help.

As they come from the factory, the brake rotors are riveted on. A replacement rotor can, but doesn't have to be,riveted back on as the lug nuts will hold the rotor in place. If you take the wheel off and the rotor hasn't been riveted back on, it is perfectly normal for it to "wobble in all directions."

Replacement rotors are relatively inexpensive and easy to find.

Put your wheel back on and while it is still jacked up, grab the top and bottom of the tire and move it in and out-check for wheel bearing play. Also, is your caliper properly mounted?

Run a couple lug nuts down (backwards) against the rotor to hold it tight against the spindle. Then you can wiggle it to see if your wheel bearings are loose/worn out.

Edit: Ken and I think alike.

Groove? Did you have braking problems? Is that why you looked at the rotor? Make sure the calipers are correct and installed correctly. On the front area of the rear rotor sometimes the parking brake cable can contact the rotor at the swing arm.

Thanks for all the help; I am going to check it out again tonight. The reason why I pulled the wheel off was that it had a ton of movment on my drive home. I have knock-offs but they were mounted tight. It sounds like wheel bearings so I am guessing that I should bring it to the mechanic.

Sounds to me like another case of the knock off wheel being mounted over the lug nuts instead of on the drive pins of the adaptor. They'll come loose in just a few miles.

A score around the rotor is not reason enough to do anything to the rotor unless it is deep enough to weaken the rotor..

Is there an update?

Thaddeus

So, I final got the diagnoses back from the mechanic today. He’s saying that my driver’s rear training arm / wheel bearings have gone bad and it looks like it will cost me a couple of bucks to fix. Has anyone used the rebuild services out there, I am going to call vette brakes in FL tomorrow morning to see if they rebuild them as I was happy with their service of rebuilding the calipers.

Bair's rebuilt the ones on my 65 while the car was still owned by some friends of mine.

Thanks for directing me to that post. Looks like I am going to use Blairs.

Are the trailing arms coded? and if so, does anyone know what the code should be for a 66 and where it is located?

Thanks again for all the help.

Make sure you do both sides.

The trailing arms aren't coded, but the spindle supports have casting dates (not visible on the car). Just call Bair's and they'll send you boxes to ship them in - they'll come back just like new.

Thaddeus

I did not realize that I should do both sides at the same time but I guess that it makes sense. I am going to attempt to install them myself so if anyone has advice, tricks or can tell me if there are any special tools need it would be very helpful.

Start with a big hammer....

Then grap the bigger one.

Any place here in Houston that rebuilds trailing arms and bearing assemblies?

Chuck Gongloff

Definitely do both sides, and PLEASE do not attempt to do it yourself.


It's a horrible, miserable job to do. You need special tools. You need a press, etc. Send it to the pros.

It's bad enough just getting them off the car.

As John Z said, Bair's in Linesville will do a great job.
