My '86 Comanche was a V6 automatic. The engine is dead, may it rest in peace. I'm trying to ID the axle ratio. I turned the back wheel and it comes up to approximately 3.5 revolutions of the driveshaft for every 2 wheel revolutions. Apparently that rules out all the ratios that are 3.31 and down and 3.73 and up.
But in my reading, I've seen 3.54 and 3.55 axle ratios as factory options for that year. But I've seen more 3.55's. Is the 3.54 a misprint, or were both axle ratios actually available for that year? If they were both available, is there a way to distinguish the two besides pulling the differential cover? When I was under there counting revolutions, I didn't think to look for a tag...
I'm contemplating an axle swap from a Ford Explorer in the hopes that it will stand up to the 5.7 liter LS1 I'm prepping to transplant into it. Anybody know if 3.54 and 3.55 ratios fairly common in those Fords?
