Hey All,
As you may have seen in another thread, I finally found my van!
2003 E350 7.3L
While I don't intend to do any rock crawling with the rig, I do plan on mobbing through snow, dirt roads, fire trails, and just generally being bad ***. To accomplish these goals, I've set my eyes on a 4" lift and 4x4 conversion from UJOR!
To that end, I started shopping around for a front axle, and that is when question number one arose.
What is my gear ratio? So far, the only indication I have found is the new vehicle sales receipt that lists a 3.55 ratio Regular Axle as an option. Since this is from 8 years ago, I want to double check. Is the best way to do this by jacking up the car and spinning the wheels?
If it does turn out that my rear end is 3.55 where does that leave me? The axles the UJOR kit is designed for all seem to be 3.73 or 4.10.
Is it possible to change the gear ratio on the axle, or does the entire axle need to be swapped?
If I am going to have to swap the entire axle, should I go for 4.10?
Does changing gear ratios at the axle affect the transmission?
Sorry if these are dumb questions. I'm really new to all this and trying to get my bearings.
