Sorry for the long description, my pervious post was ereased and hate to rewrite it all, so i copied something i sent to someone already.

This fall i put on the LS1 brakes to my LT1 car. I had no problem with the install but just a couple of weeks ago i tried to take it out around the neighborhood for the first time since the upgrade and when i went down the drive way i felt a weird feeling from the front pass. wheel. I got on to the road and coasted about 10 yards and felt the weird feeling again. It felt like there was a bump on the tire and when the tire rotated it would hit this point and it would feel like the tire was rubbing again something for a split second, with that the steering wheel would turn to the left. It felt like the wheel wasn't on tight and it was slipping off.

I pulled it back into the garage and jacked it up. I turned the wheel and nothing felt out of line and the tire rotated smoothly. I just backed it out of the garage and took the wheel off and could not see anything wrong. Now when I backed it out i did not feel the weird bump like it did in the first time, but the only thing i can see is that when one wheel is straight the other is a little off. Would this be normal after the upgrade. I know i need an alignment, but would you point out anything that i could have done wrong. I check the ball joint and its nice and stiff, the pads are new, the wheel turns fine when the car is in the air. I reused my hubs and i made extra care not to mess them up cause the ones that came with the spindles were cracked were the sensor is. What would a bad bearing be like? Please could you suggest any thing for me to check again

 

Sounds like warped rotors.

 

I put 98+ brakes on my 96. YOU NEED AN ALIGNMENT AFTER THE SWAP. A friend of mine tore up a front tire just driving ~20 miles to get his aligned. Get the car aligned, that is the problem.

 

Thanks for the replys. I didn't think it was the rotor cause when the car was in the air the wheel spun fine.

I was just curious if the alignment could be that far off. Or might it be something worse?

I think i might have the car towed and get the alignment.

 

Yes, the alignment can be that bad. Because the wheels are pointing in different directions (even slightly), the car will handle poorly and the tires/suspension will make a lot of noise.
