Axle question?

What year(s) explorer 8.8 axle will fit without modification under a YJ? How can I tell what gear ratio is in my axles without removing the rear cover? Thanks. Hope everyone had a good Thanksgiving.

These are all really common questions which have been answered thousands of times before. I, respectfully, suggest you try the search.

I'm lazy and find it easier to just ask. LOL. Point taken. I'm new to the forum And have searched. I am looking for confirmation and thought I would throw the axle question in while asking the ratio question.

If there is no tag on the diff cover anymore then I would do the following.

Jack up the rear end, transmission in neutral, rotate the tire one rotation and count how many times the driveshaft rotates.

The number of driveahaft rotations to one wheel rotation is your gear ratio.

OR

Count the ring gear and pinion gear teeth. Divide to get gear ratio.

And the 8.8 will need you to reweld the perches to do it right. They aren't bolt in. Lots of threads on this topic. Should be able to find all the info ya need in a couple min. It's definitely a pretty easy swap. 95+ is the desireable years because of disk brakes

Exploder 8.8's aren't bolt in. There are companies that weld on new perches and stuff, but otherwise stock 8.8's aren't bolt in.

All about that unibody life.

If I get a older axle with drums, is it as simple as remounting perches?

Well, there have been guys that simply bolted them in, but I wouldn't go that route. Perches are cheap, grind the stock stuff off and weld new ones on were they need to be, plus shock tabs, that about covers the welding, everything else from there is pretty easy. The differences in brakes really have no bearing on install.

Use the search box at the upper left of the screen. Using the search tool located on the middle-right just doesn't give as much info. When I figured that out I got better results.
