1970 mopar e body.
i learned the hard way that there are 2 types of green bearings: an older, 'bad' RP400 model and a newer, 'good' MO400 model (snap ring). unknowingly, i had previous installed the older RP400 style on my car and it would growl loud and nasty every time i drove 50+ mph and then slowed down and started making turns. wouldn't stop growling until i turned off the car and let it cool down. after much forum discussion, i learned of this newer 'snap ring' style as presented here. i purchased from quick performance and installed immediately. sure enough, it's been quiet and smooth ever since. i highly suggest the green bearings, just make sure it's this one!
full details about the difference in styles can be found why searching for Dr. Diff's "Why Green Bearings?" blog |
