rpm

There are a few charts out there showing the RPM’s that you run with certain axle gears with certain tires at a given speed. I used one of these such charts from one of the posts I stumbled across on this website a long while back. Sorry, I don’t remember where I found it on here. I got tired...

Hey guys, I'm looking for some help and this is a strange one... Recently I did a bit of work to the cooling system on my 1997 Ford Ranger 3.0 XL, and after the work I now have a vibration/shudder/rumble that occurs at 3k rpm and up. What's weird about it is that prior to doing this work, I...
