3L73 diff tag then. lol. You'll like the 3.73's. It'll really put some pep in the truck and it'll drive awesome and still pull some really killer mpg numbers. My brothers truck is geared to 4.10(3.73 gears and 25" tires) and he pulls 35 on the highway out of his 2.5 5spd.

The mpg would be a nice bonus. I was more concerned about being able to pull my utility trailer with the truck if I need too and better traction in wet and snow conditions. After reading the Owner's manual on what it had to say about the 3.45 rear end and towing, I couldn't believe they would do that to a truck. "towing not recommended" - WTF?!?!

LOL.....Hell....I wouldn't tow with that 2.5 with even a 4.10 ratio! gutless wonder WHEN EMPTY!!!! I can't imagine a 3.45 with a loaded tailer! LOL

The 3.45:1 rear end must be too high of a ratio for towing. A 3.73:1 has a max towing rating of 1580 or there abouts (pulling the number off the top of my head).

Anyway, My 4' X 8' utility trailer is full of camping equipment, more than what will fit in my 6' bed. The trailer is longer and the sides are taller. Plus, with the high boy cap, stringing a canoe on top doesn't work well (I saw the previous owner do it and it was dicey to say the least). My trailer has a rack for hauling the boat as well.

Also, I have plans to get a motorcycle next year and I don't think it will fit in the bed even with the cap off. The utility trailer sides are removable and the bed tilts. It would be much better to load the bike on that if I need to trailer it.

As far as the comment on trailering with a 2.5L, true enough, it is a gutless wonder but if my CR-V with a 2.0L can do it and do it well, the Ranger should be able to do a decent job. Now the CR-V has 146 hp vs. the Ranger's 119 but the torque is the same. Four bangers, especially with a stick are much more capable than people give them credit for.

There are a few rear ends available in 7.5" and 8.8" available for the Ranger depending on the year your Ranger was made for the 2.5L engine.

From what I've seen, there is the 3.45:1 (high way gear, meaning it's a tall gear and is supposed to be the most fuel efficient) available on the manual transmission only, the 3.73:1 which is available on the manual or the automatic transmission and is a compromise between the tall gearing of the 3.45/3.55 and the low gearing of the 4.10, and the 4.10:1 which is available on the automatic only and is a low gear.

The 4.10:1 rear end allows more "grunt" at the rear wheels but there is a penalty in fuel efficiency and more rapid shifting. I've known people who have had the 4.10 rear end in full size trucks that almost never use first gear because of the rear end with their manual transmissions.

The cheapest source would be a junk yard. I expect that the Explorer rear ends will be similar to the Rangers but I'm not sure.

You can get a limited slip differential in either 3.73 or 4.10 if I remember correctly. I'm not sure about a full locking rear end, at least not without some additional equipment. I think locking rear ends have an additional electronic mechanism in the differential but I could be wrong.

I hope this clears things up for you some.

You'll have to look on your door jam for the axle code or crawl underneath ad look at the metal tag that should be on one of the differential cover bolts. There is a thread on here that will tell you what you have. Or you can call a dealer and give them your VIN.

Limited slip is just that, limited slip (it still slips, just not as much). Most LSDs will distribute up 50% of the power to the wheel that isn't slipping. In most on road situations, that is all you need.

A locking differential fully locks both wheels together so there is no slippage. These should only be engaged if there is snow on the road or if you are off road or you will eventually break something since there is no give in the differential.

As far as conversion, the easiest way is to swap rear axles but it is not the cheapest. Buying a LSD for your differential is cheaper but much more labor intensive and it is much easier to mess something up.

That is why I'm opting for the whole axle route. While I'm pretty sure that I'm perfectly capable of doing a differential change, since I'm looking at changing the gearing as well as getting an LSD, it makes more sense for me to go that route in my mind. It will be a hell of a lot easier.

The easiest way is to locate an axle at the junk yard with the ratio you want and LSD. It will probably be the cheapest route as well. You will probably want to stick with whatever gear size you have now (7.5" or 8.8"). That's the route I'm going. You'll be looking in the neighborhood of $400 +/- going that route.

Disconnect the the drive shaft, the brake line, the parking brake cables, the ABS sensor connections, and the u-bolts for the springs. You will have to see what the salvage yard leaves on or cuts off the "new" axle and swap whatever they cut. Everything should be the same except for what is in the differential.

It might be a good idea to change the differential oil and don't forget to put some additive for the LSD in there as well. I can't remember how much additive is needed, I think the owner's manual or the service schedule available on the ford web site said how many ounces were needed. If the "new" axle cover is like mine, you'll need some RTV for the differential cover since there is no drain plug on the cover; the whole thing will need to come off.

You may also need to replace the u-bolts and the brake lines on the "new" axle depending on what kind of condition they are in.

Edit: Another member mentioned that the yoke might be different, so you might have to swap that over. The nut that holds it in place is either 3/4" or 1".
