Hi there. Long time lurker first time posting. Have a 59 3100 apache fleet 4 speed all stock. Nice daily driver for around town. Bought Patrick's 3.38 kit with the bearing kit and got it all in yesterday. Everything went fine but now at rpm it sounds noticeably louder. Idle sounds the same and everything seems OK but I was just wondering if these 3.38 ring and pinion kits have changed the rpm noise in your guys truck? Just want to make sure its the way it is and not something I screwed up. Thanks in advance for any info you can offer..
