What was in it before? If a 4.10, then you are probably doing 60, not 50. If the rear is howling you need to adjust it. Get the swipe pattern right, or you may be changing the rear again before you know it. Many guys here have done it, so there will be a lot of advice available. The rear set-up is on of those things you have to get right, close doesn't cut it.
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
