Thanks MJ,
I will double check 2, 4 and 5. 1 and 3 have been eliminated.
I replaced the rear bearings when I did the Wilwood conversion, but I could have mucked it up somehow. Will double check the parking brake too.
Does the rack need to come out to check everything?
The pull felt like it was from the front, but this is only because steering wheel was "yanked" out of my hand when it happened. I guess the front would follow the rear if it was locking up in the back.
Thanks,
John
