Thanks Malc...... I like the spool in my car but I had to much chatter when the wheels are turned>> Maybe that will help.
Your not going to believe this.... I put the pro spec alum. diff in front last winter about a mouth before carpet was over and have not touched it sense. I think I can get the whole summer in with it, I put the POM pro spec in back last month and it's as smooth now as it was when I put it in and nether one slips at all. (use the stick on Shields) I run mod and drive at lest 2 times a week on asphalt !!!!
