RE: IML: 70 rear axle

In my experience anyway, MOST Chrysler cars came with 3.23s as the standard rear-end gear set. Our '64 Crown has them, and so does our '72 Cuda. I would think the 2.94s would just make you have to push the peddle a little further to the floor (more gas) to get things moving. With the 3.23s, it will get going a little better (up hill too), but of of course your top-end speed will be down a bit, is that ok?

Setting up the axel is not "difficult", but it does require attention to detail, particularly when setting the ring gear backlash and the pinion depth. Read up on it, and make check of required tools. What may (or maybe not) shock you is the price of a new limited-slip differential for that axle. It won't make you move down the highway any better, but may help in the snow, sand, or mud.

Subject: IML: 70 rear axle

Hey everyone, I have an issue with my rear axle that is tearing me up. I need to replace the bearings ( sounds like a church choir in my trunk ) and I would like to install taller gears and a limited-slip diff while I am in there. Here is my problem: I would like to go from the current 2.94 to a 3.23 for a little extra "go" and better towing capabilities. If my calculations are correct, that would be an increase of approximately 200 rpm at 65 mph. Will that increase make my highway hauler not so highway. My main goal with this car is road trips. And one last question: Is rebuilding an axle difficult? I rebuilt my transmission myself ( with a little help from my brother ) and that was easy.

P. S. I want to thank everyone for their support. I was asking a few weeks ago if I should keep her or set her up for adoption. As you can see, I am keeping the little @!&^%$(&^...........
