Just an update with even more gear issues
Not sure if I stated before but bought a R&P setup from Lucky8. 4.12 Ashcroft. Looks good and had it installed into one of the open Rover diffs I had around.
Put the 3rd in the front last week and then thought I was good - so checked the tire rotation with 2 side tire up in the air. Figured they would be rotating the same but nope.
Recount front - just over 4 rotations with 2 turns of the front wheel.
Count back and low and behold 3 3/4 turns of the output flange. WTF? In my rush, I must have counted the rear wrong when I went to put that ARB in.
I pulled the rear shaft this time and drove the truck locally over the weekend. Finally pulled the rear 3rd today and counted gears - 41R x 11P - yup 3.72 ratio.
This is either getting funny or pathetic. It's definitely getting expensive. 2 diffs bought being told they had 4.1 gearing and both with different actual ratios. I feel like an asshole that I didn't count teeth while they were on the floor and now I am paying. Looks like Toy R&P's are cheaper than Rover but by the time I get the R&P, and bearing kit and installed it will be more than what I payed for the diff itself (this isn't taking into account all the BS work I have had to do swapping things around and the expense of buying gaskets and gear oil).
Anyway - I'm super bummed out on this whole thing. I want to grenade my truck and go ride bikes - much cheaper and less headaches.
