well guys I got good news and bad news. Good news is I found out what is causing my rear to vibrate, my damn driveshaft is bent. Not in the middle but one or both ends of the shaft where the u joints fit into the driveshaft itself is slightly bent inward or outward. How I do not know but im having a hard time finding a place that is able to fix the aluminum shaft back to perfect. SOOOO my question is, what years have the aluminum driveshaft. I found out that only 4x4 supercab ones will fit, and im pretty sure auto and manual dont matter because on 4x4 it bolts into the transfer case. So what year rangers have the aluminum 1 piece that will fit my 06 supercab 4x4 one? also someone suggested that I should just try and get a steel one like the old design but I figure this wouldnt be a good option but idk maybe it could work, any thoughts???
